Django in production doesn't serve static files, it's only in development when debug=True, have you accounted for that?

[lavish ferry]

Anychance I can get a hand here, no matter what I do this validation always fails:

class Cipher147Form(FlaskForm):
    encrypt = SubmitField('encrypt', validators=[Optional()])
    decrypt = SubmitField('decrypt', validators=[Optional()])
    nonce_options=["hybrid", "random", "time"]
    encoding_options=["base85", "base64", "base32", "base16"]
    key = StringField('key', validators=[InputRequired()])
    text = TextAreaField('text', validators=[InputRequired()])
    nonce = SelectField('nounce', validators=[InputRequired()], choices=nonce_options)
    encoding = SelectField('encoding', validators=[InputRequired()], choices=encoding_options)

@app.route("/encryption/147cipher", methods=['GET', 'POST'])
def cipher147():
    form = Cipher147Form()
    if request.method == "POST":
        if form.validate_on_submit():
            key = form.key.data
            text = form.text.data
            nonce = form.nonce.data
            encoding = form.encoding.data
            if form.encrypt.data:
                output = encrypt_147(key, text, encoding, nonce)
            elif form.decrypt.data:
                output = decrypt_147(key, text, encoding)
            data = [key, text, encoding, nonce, output]
            return render_template('encryption/147cipher.html', title="147Cipher", form=form, data=data)
    else:
        return render_template('encryption/147cipher.html', title="147Cipher", form=None)

Here are my imports:

from flask import Flask, render_template, send_from_directory, request
from flask_wtf import FlaskForm
from wtforms import form, StringField, TextAreaField, SelectField ,SubmitField
from wtforms.validators import InputRequired, Optional, length

Here is the HTML bit:

<form method="POST">
    {{ form.csrf_token }}

And I do set the key:

# Pull secret key.
app.config['SECRET_KEY'] = os.getenv('CSRF_KEY')

[opaque rivet]

have you checked form.errors to see which fields are failing?

[lavish ferry]

No I don't know how to get that to print somewhere

[lavish ferry]

How can I do that?

[opaque rivet]

print(form.errors)

[lavish ferry]

I did try that and it didn't print...

[opaque rivet]

show code

btw, if request.method == "POST": is irrelevant, form.validate_on_submit(): checks that the request method is POST iirc

[lavish ferry]

Oh nice

Thanks

I tried this and I get no print in the terminal

@app.route("/encryption/147cipher", methods=['GET', 'POST'])
def cipher147():
    form = Cipher147Form()
    if request.method == "POST":
        if form.validate_on_submit():
            key = form.key.data
            text = form.text.data
            nonce = form.nonce.data
            encoding = form.encoding.data
            if form.encrypt.data:
                output = encrypt_147(key, text, encoding, nonce)
            elif form.decrypt.data:
                output = decrypt_147(key, text, encoding)
            data = [key, text, encoding, nonce, output]
            return render_template('encryption/147cipher.html', title="147Cipher", form=form, data=data)
        print(form.errors)
    else:
        return render_template('encryption/147cipher.html', title="147Cipher", form=None)

does errors need imported?

[edgy anvil]

its set to deub = false and that wasn't the problem

[opaque rivet]

yeah when debug=False django does not serve staticfiles, another server is meant to serve staticfiles. maybe amazon s3 bucket I've heard, but I don't have any experience doing it

[lavish ferry]

I removed the if POST, though yeah I still don't know how to actually print the errors

[edgy anvil]

apparently i had many other things wrong with my stuff and when i was testing everything locally so i thought i didn't have any errors with my django stuff but i did and that became evident when i tested it on the aws server

[opaque rivet]

if form.validate_on_submit():
  # form stuff
else:
  print(form.errors)

see if that gets anything in your console

[lavish ferry]

Without the else returning the rendered_template, I can't render the template to test if with inputs in the form.

One sec...

Oh weird

It thinks the token is missing

{'csrf_token': ['The CSRF token is missing.']}

[opaque rivet]

did you set your env variable CSRF_KEY?

os.getenv('CSRF_KEY')

[lavish ferry]

Yes

# Pull secret key.
app.config['SECRET_KEY'] = os.getenv('CSRF_KEY')

[opaque rivet]

that's retrieving the env variable, did you actually set it?

[lavish ferry]

Yes CSRF_KEY=key

That isn't the actual key but you get it

in the .env

[opaque rivet]

hmmm... inspect the page source and see if there's a hidden field with the csrf key

[lavish ferry]

I am not sure how to do that

Though I can try...

[opaque rivet]

right click on the page in the browser, inspect element, check the html code for your form. see if there is a hidden input for your csrf key

[lavish ferry]

Oh

Well there is a gap where the key should be...

<form method="POST">
    
    <div class="card">
        <div class="card-body">
            <div class="row">

This is what should be there:

    {{ form.csrf_token }}

Yes, localhost

There is this weird thing called wtx-context everywhere

Also a weird dashlane thing... which is odd.

[opaque rivet]

hmm, I don't use flask so it's hard to say, but if you don't see any hidden inputs for your CSRF token in the form that's the problem...
are there no errors in your flask server?
might want to check that the SECRET_KEY is actually populated

[lavish ferry]

To be fair I have no idea what I am looking for when it comes to hidden inputs

How would I check it is populated

[opaque rivet]

it'll be something like:
<input type="hidden" name="CSRF_TOKEN" value="csrf_token_here"></input>

[opaque rivet]

by printing it

[lavish ferry]

Printing it says it is none

Fixed it

Needed this right before the </form>

<input type="hidden" name="csrf_token" value="{{ csrf_token() }}">

Also needed this at the start:

csrf = CSRFProtect()
app = Flask(__name__)
app.config['SECRET_KEY'] = os.getenv('CSRF_KEY')
csrf.init_app(app)

What a nightmare lol

Thanks for your help Nicky, I was going crazy. Glad you were here to talk me through where I should focus, was a massive help.

   return render_template("User/Homepage.html",student=current_student,form=form)
```py

this getting kinda ugly somehow a lot of code and stuff but anyway
im struggling to make this code cleaner anyone please

[native tide]

what would cause a request body to be formatted like this in my packet sniffer

[raw compass]

encryption, a binary file, or a text file with a non default encoding.

When is it ok for a csrf_token not to expire with a wtf_form

Since it disappears with session end anyway.

I'm building a simple API using the Flask module, does anyone know how to add an image to it?

[lavish ferry]

Hello!

[knotty musk]

Hi!

[lavish ferry]

You will need to elaborate on what you mean by add an image to it

[knotty musk]

im gonna send the code

`import time
import tkinter
import flask
from flask import Flask
from flask import request, jsonify
import flask

app = flask.Flask(name)

app.config["DEBUG"] = False

@app.route('/')
def home():
return "<font color='#00ff00'><h1>Hi baba</h1></font><marquee><font color='#00fa9a'><p>I hope you become better!</p></font></marquee><p>If you viewed this click this button</p><button><a href='http://192.168.100.2:5000/hello'>Click this!</a></button>"

@app.route('/hello')
def hello():
return "<font color='#00ff00'<h2>I hope you get well soon!</h></font><button><a href='http://192.168.100.2:5000/p3'</a></src></button>"

@app.route('/p3')
defp3():
return '3rd page lol'

app.run(host='0.0.0.0')` So basically i want the "p3" to return the code for an image to be displayed on http://192.168.100.2:5000/p3

So basically i want the "p3" to return the code for an image to be displayed on http://192.168.100.2:5000/p3

Im pretty new lol

[lavish ferry]

Do this around your code:

[knotty musk]

ok thank you!

[lavish ferry]

When showing it on Discord I should add

As far as returning an image, could just add it to the html to my knowledge. Also probably nicer if you use render_template()

[knotty musk]

ok tysm

Hey guys, I have a form in Django and I want to redirect the user to the newly created object after submission, but I get this error:

The view hrm.views.volunteer_create_view didn't return an HttpResponse object. It returned None instead.
Here is my code:

def volunteer_create_view(request):
    form = VolunteerCreateForm(request.POST or None)
    if form.is_valid():
        new_vol = form.save()
        messages.success(request, 'Volunteer created sucessfully')
        return HttpResponseRedirect(reverse('hrm:person', args=(new_vol.id)))

[uneven mango]

I have learned python

Now i wanna start

Web development

So which one will be good

Flask or django

I know difference between flask and django but i just cant get myself to decide

[versed python]

You're not handling the case when form is invalid

[versed python]

Some people would say flask. I personally started with Django and really enjoyed it.

Just choose one and go

You'll probably end up learning both

[native tide]

so I have to enter an else?

[uneven mango]

I guess i will go with django to

[versed python]

yes

[obsidian steeple]

im starting with quart (flask but async)

[uneven mango]

Oh ok

[knotty musk]

I installed Django but when i want to start a project it says that the command "django-admin startproject mysite" is unknown

[mint siren]

you have to make a virtualevnviroment

[stark tartan]

try pip freeze

[mint siren]

pip freeze will tell you which modules you have installed and am certain django will be one of those models but you can't run the cmd like that. Just use virtualenv https://docs.python.org/3/library/venv.html

[mint siren]

Django is better and smoother and more organized

[uneven mango]

I see ok

Thanks

[mint siren]

i'd suggest flask for apis tho

[elder nebula]

Why is this starting week on wednesday? Appointment(date__week_day=date.weekday())

[glossy scroll]

Using django 3.2
should i do this or not?

or should i just pass my object in the view logic as context

[elder nebula]

You should do as much on views.py as you can

[glossy scroll]

Any reasons besides readability

Not to sound ignorant but is there any hits on performance ?

[elder nebula]

Django is designed in a way on purpose that you have to do most of the stuff on views.py because it makes the app more secure

Templates are served for everyone so it's more vunerable

[glossy scroll]

oh

so how much flexibility do i have with the request object in the template context

[elder nebula]

you have all the same request things that template has

[glossy scroll]

i cant understand what you're trying to say

[next comet]

He means that its better to put that thing in the context so the template doesn't involve the logic to call it

I guess

[elder nebula]

Yes, because html templates are unsecure and views.py is made to do the logic for you

[glossy scroll]

oh i get it now

thanks

[hardy laurel]

Hello. I'm using Wagtail and I want to create a page with custom parametrized route

Like /something/4

currently I do this :

def Success(request, year):
    name = {
                'resp': year,
            }
    return render(request,"response/response_page.html",name)

With

urlpatterns = [
    path('resp/<int:year>', views.Success),
]

which works, shows the page but doesn't show the wagtail page with content modified from the CMS, just an empty HTML

because the Slug is equal to resp in wagtail

[dusk portal]

def login(request):
    if request.method=='POST':
        username=request.POST.get('username')
        password=request.POST.get('password')
        user=authenticate(username=username,password=password)
        if user is not None:
            return HttpResponseRedirect('/')
        else:
            return render(request,'users/login.html')
    return render (request,'users/login.html')``` idk why but when i'm using the login panel and enter correct password (of any user ) so it  do not works but if i enter id password of admin there that works

from django.contrib.auth import authenticate
from django.shortcuts import render
from django.http import HttpResponseRedirect
from django.contrib.auth.models import User 
``` ig error can be in 1st import cez idk authenticate

umm

[opaque rivet]

@dusk portal are your users stored in the User model?

@glossy scroll just for readability sake, keep most if not all of the logic in the view.

[glossy scroll]

so its only readability?

[opaque rivet]

Yeah - whether you're accessing data from the request in the view then passing it to your template or accessing request directly from the template, there is no difference. It's just readability, and to debug an issue it helps having it all in one place

It's not "more vunerable" as someone said.

[compact glacier]

hello guys, working on Django project and sending to template dict that have 1 item - list of dicts, trying to parse it in template and get info but nothing works (

how i send to template:

    # db_worker.write_to_db()
    data = db_worker.read_db(1)
    dic = {'data': data}
    return render(request, 'main/blocks.html', dic)```

what contains *data*:

part of HTML template:
```<table>
        <tr>
            <th>height</th>
            <th>hash</th>
            <th>timestamp</th>
            <th>miner</th>
            <th>transactionsCount</th>
        </tr>
        {% for val in dic.data %}

            {% endfor %}
        {% endfor %}
    </table>```

but it not work

tried couple of methods

[opaque rivet]

{% for val in dic.data %}

dic is the context. You can't access the objectdic within dic, only the keys within dic.
so this should be:

{% for val in data %}

[compact glacier]

still not works

[opaque rivet]

well that's not the only thing you have to change, your logic here is incorrect, try to fix it:

{% for i in val.values %}
                <tr>
                    {{height}}
                </tr>
                <tr class="even">
                    {{hash}}
                </tr>
                <tr>
                    {{timestamp}}
                </tr>
                <tr class="even">
                    {{miner}}
                </tr>
                <tr>
                    {{transactioncount}}
                </tr>

[compact glacier]

you mean troubles in html?

[opaque rivet]

syntax and logic

[compact glacier]

im pretty new in thes sphere

[opaque rivet]

Ok you're looping through each value in the dictionary:
{% for i in val.values %}
but then you're trying to access variables that were never defined?

<tr class="even">
                    {{hash}}
                </tr>
                <tr>
                    {{timestamp}}
                </tr>
                <tr class="even">
                    {{miner}}
                </tr>
                <tr>
                    {{transactioncount}}
                </tr>

[compact glacier]

{{hash}} for example isnt key that im just call ?

[opaque rivet]

If you simply want to loop through the values:

{% for i in val.values %}
  <tr>
    {{i}}
  </tr>
{% endfor %}

[opaque rivet]

no, what you're doing there is trying to get the hash variable from context...

also, how can you even access keys? You're looping through val.values, which are the values not the keys of the dict

[compact glacier]

    try:
        info = api_requests.req_info()
        return render(request, 'main/index.html', info)
    except:
        return HttpResponse("Something went wrong")```


```    <ul><h3>
        <a href="/admin" ><h1>Admin page</h1></a>
        <a href="/blocks" ><h1>Blocks page</h1></a>
        <br><br>
        <li>height: {{height}}</li>
        <li>supply: {{supply}}</li>
        <li>circulatingSupply: {{circulatingSupply}}</li>
        <li>netStakeWeight: {{netStakeWeight}}</li>
        <li>feeRate: {{feeRate}}</li>
        <li>dgpInfo: {{dgpInfo}}</li>
    </h3></ul>```

Here im not defining anything, just sending dict and then pulling keys

[compact glacier]

            <tr>
                {{height}}
            </tr>
            <tr class="even">
                {{hash}}
            </tr>
            <tr>
                {{timestamp}}
            </tr>
            <tr class="even">
                {{miner}}
            </tr>
            <tr>
                {{transactioncount}}
            </tr>
        {% endfor %}```

changed to this


and as i think val should contain these keys

[opaque rivet]

okay, so does this work?

[compact glacier]

nope

[compact glacier]

as u can see here, it doesnt

thats why im really confused, why it not works

[opaque rivet]

no, the code which I am replying to

does that work?

[compact glacier]

yesm it works

but in that case im sending only the dict as JSON

[sudden gulch]

hey i have a questio
django default db is sqlite and all its authentication tables uses it so if i change my db to mongo can i still able use default authentication tables

[compact glacier]

i changed to PostgreSQL

and made model

    hash = models.CharField(max_length=100)
    height = models.CharField(max_length=9)
    timestamp = models.CharField(max_length=50)
    miner = models.CharField(max_length=100)
    transactioncount = models.CharField(max_length=3)```

[sudden gulch]

ok so all things remain same just like in sqlite

[opaque rivet]

Ok, I'll explain why:

With the code that works, you're passing the context info, let's say it's this:

info = {
  height: x,
  supply: y,
  circulatingSupply: z
}```

In your template, when you do `{{height}}` you are accessing the key `height` in your context, so that will work. It will show `x` in the template.

In your non-working code, your context is now this:

```py
{
  data: {
    height: x,
    supply: y
  }
}```

so doing `{{height}}` is no longer valid. You have to do `{{data['height']}}`

[compact glacier]

then pulling and pushing with these code:

from . import api_requests
import json


def write_to_db():
    blocks = api_requests.req_block()
    conn = None
    try:
        conn = psycopg2.connect(host="localhost", database="crypto", user="postgres", password="admin")
        cur = conn.cursor()
        for element in blocks:
            cur.execute(f"INSERT INTO main_block (hash, height, timestamp, miner, transactioncount) VALUES"
                        f" ('{element['hash']}', '{element['height']}', {element['timestamp']},"
                        f" '{element['miner']}', '{element['transactionCount']}');")
        conn.commit()
    except (Exception, psycopg2.DatabaseError) as error:
        print(error)
    finally:
        if conn is not None:
            conn.close()


def read_db(offset):
    conn = None
    try:
        conn = psycopg2.connect(host="localhost", database="crypto", user="postgres", password="admin")
        cur = conn.cursor(cursor_factory=psycopg2.extras.RealDictCursor)

        cur.execute(f'SELECT * FROM main_block OFFSET {offset} LIMIT 5;')
        fetch = cur.fetchall()
        dic = {}
        data = []
        for i in fetch:
            dic['hash'] = i['hash']
            dic['height'] = i['height']
            dic['timestamp'] = i['timestamp']
            dic['miner'] = i['miner']
            dic['transactioncount'] = i['transactioncount']
            data.append(dic.copy())

        return data

    except (Exception, psycopg2.DatabaseError) as error:
        print(error)
    finally:
        if conn is not None:
            conn.close()

[sudden gulch]

modelforms

all the things work same?

[opaque rivet]

yes, but to change db server there's some setup

[compact glacier]

in my case its

{'smth': data}

data:

[{...}, {...}]

[sudden gulch]

that i know i was just worried that if i change it will i able to use django auth.

[opaque rivet]

I know... I'm telling you why this doesn't work, you can change it so it starts to work. I'm not trying to give too many hints here...

{% for val in data %}
            <tr>
                {{height}}
            </tr>
            <tr class="even">
                {{hash}}
            </tr>
            <tr>
                {{timestamp}}
            </tr>
            <tr class="even">
                {{miner}}
            </tr>
            <tr>
                {{transactioncount}}
            </tr>
        {% endfor %}

[opaque rivet]

you'll still be able to use it.

[sudden gulch]

thnx for the help bro

[opaque rivet]

@compact glacier in this code, I want you to understand you are trying to access the height key in your context, instead of the height key of an item in your dict. You see that?

[compact glacier]

yeah

[opaque rivet]

Ok, so you just need to change it so you're accessing the height key of each item. Here's an example:

{% for key, value in data.items() %}
            <tr>
                {{key}}: {{value}}
            </tr>

[compact glacier]

            <tr>
                {{data['height']}}```

tried this one, and got error
```django.template.exceptions.TemplateSyntaxError: Could not parse the remainder: '['height']' from 'data['height']'

oh

with {% for val in data %} <tr> {{val['height']}} </tr>
these one not same

[compact glacier]

as this

got error

django.template.exceptions.TemplateSyntaxError: Could not parse the remainder: '["height"]' from 'val["height"]'```

[opaque rivet]

what is your context again?

[compact glacier]

the thing is that even when im trying just to print val it shows nothing

[compact glacier]

tried to make code as u said like this:

            <tr>
                {{val["height"]}}```
and got error above

[opaque rivet]

yeah, so what is the context you are passing to your template?

[compact glacier]

[{"hash":"384f3e42b8e26443bc1087a0387827146a41f9d3ef663a7d7eda82c927e78bf2","height":"315012","timestamp":"1624372128","miner":"BTJi34JG4dmL5GbTYgDdp8Nyb7Mhpsd1az","transactioncount":"2"},{"hash":"bcf54ece598e7def8fedfea23c2f4cce7bd2d1ec35351fe9f4d8523ac2fa26de","height":"315011","timestamp":"1624372016","miner":"BTJi34JG4dmL5GbTYgDdp8Nyb7Mhpsd1az","transactioncount":"2"},{"hash":"aef7e142303e54c08f885965877199f6af6ee4da8687eed8505e6a4fb41ef446","height":"315010","timestamp":"1624371920","miner":"BTJi34JG4dmL5GbTYgDdp8Nyb7Mhpsd1az","transactioncount":"2"},{"hash":"50ca063a86f434ce08e7e8537808662a0e782935eb5e72bdb506c5e32b5a3391","height":"315009","timestamp":"1624371808","miner":"BTJi34JG4dmL5GbTYgDdp8Nyb7Mhpsd1az","transactioncount":"2"},{"hash":"f592d181a1bec34566509152d1e0e5ac8531ae23b5a91e6bec27ade3001e69bf","height":"315008","timestamp":"1624371648","miner":"BTJi34JG4dmL5GbTYgDdp8Nyb7Mhpsd1az","transactioncount":"2"}] list of dicts

[compact glacier]

as u can see here

and all this stuff is packed in a dictionary

Maybe theres some easier methods to send this stuff to page instead as one of params of render

but i dont know

[opaque rivet]

well you can try:

{% for item in data %}
  {% for value in item.values() %}
    <tr> {{ value }} </tr>
  {% endfor %}
{% endfor %}

the previous example should work, print the type of your data to ensure it's a list and not str

[compact glacier]

<class 'list'>

[opaque rivet]

ok, try above example

[compact glacier]

            {% for value in item.values %}
                <tr>
                    {{value}}
                </tr>
                <tr class="even">
                    {{value}}
                </tr>
                <tr>
                    {{value}}
                </tr>
                <tr class="even">
                    {{value}}
                </tr>
                <tr>
                    {{value}}
                </tr>
            {% endfor %}}
        {% endfor %}```

made this one, not shows anything

[opaque rivet]

{% for value in item.values() %}

[compact glacier]

it not works

Keep in mind that for the dot operator, dictionary key lookup takes precedence over method lookup. Therefore if the data dictionary contains a key named 'items', data.items will return data['items'] instead of data.items(). Avoid adding keys that are named like dictionary methods if you want to use those methods in a template (items, values, keys, etc.). Read more about the lookup order of the dot operator in the documentation of template variables.

https://docs.djangoproject.com/en/3.2/ref/templates/builtins/

from official documentation

[opaque rivet]

ah ok

weird... that should work.
maybe just list what's in your data key?

{% for item in data %}
  {{ item}} 
{% endfor %}

[compact glacier]

nothing, it shows nothing

[opaque rivet]

implies that your context is empty?
try:

{{ data }}

see what that gives.

[compact glacier]

well found an mistake

and fixed it

    data = db_worker.read_db(1)
    sdata = {'first': data}
    return render(request, 'main/blocks.html', sdata)```

i was changing name of key in dict, so the screenshot above is the result of this code:

     ```   {% for item in first %}
            {{item}}
         {% endfor %}```

[near bison]

I am trying to implement a system where i have a FastApi backend. And It's needs to perform some operation outside the request response process.

Ex :

• I have an endpoint that accepts some data
• I need to add that data into some list (persistent)
• As long as the queue is not empty i need a particular process to run (separate thread?). This process may also contain websockets to update the front_end with what is going on
• if the list gets empty the process should stop, but should start running again if anything gets added to list

How do i implement this in a uvicorn and fasapi compatible way ?
Thank you

[compact glacier]

ok, we have a promotion,

item.hashshows what i need, but in weird place

now HTML code looks like:

                <tr>
                    {{item.height}}
                </tr>
                <tr class="even">
                    {{item.hash}}
                </tr>
                <tr>
                    {{value}}
                </tr>
                <tr class="even">
                    {{value}}
                </tr>
                <tr>
                    {{value}}
                </tr>
        {% endfor %}```

@opaque rivet thanks a lot for your help.

I changed a bit code. Now it looks like that:

        <tr>
            <th>height</th>
            <th>hash</th>
            <th>timestamp</th>
            <th>miner</th>
            <th>transactionsCount</th>
        </tr>

        {% for item in first %}
                <tr>
                    <td>{{item.height}}</td>
                    <td>{{item.hash}}</td>
                    <td>{{item.timestamp}}</td>
                    <td>{{item.miner}}</td>
                    <td>{{item.transactioncount}}</td>
                </tr>
        {% endfor %}
    </table>```

and it works.

ffs is there any way that i can make forms.RadioSelect widget to appear as checkbox and not that ugly circular buttons?

[whole crow]

Leaving them their default look will help people understand how they will work.

[next comet]

yeah didn't think of that, but my problem is that I have a images, that have a category, but i can't make an image have a more than one category and have to work with only 1 category per image, so my idea was to use a widget and appear as checkbox

[whole crow]

you want it to work like a radio button, so why not present it as a radio button?

[next comet]

i can make it work with checkboxes if i override the CheckboxSelectMultiple but it will be buggy af probably

well best case is if I can make an image have 1 or more categories and be able to choose this in the form when posting the image

[whole crow]

you haven't said why you want it to look like a checkbox

[next comet]

well i like it better, but if we put that aside, i just wanna learn if there is any way I can make it to look

[whole crow]

sorry, i don't know if there's a way

[next comet]

it's okay

[opaque rivet]

you can apply custom classes to it, to modify its look. Generally though when using premade modules from django you don't get a lot of customization. It's best to DIY.

[ivory bolt]

hey everyone! Been a while and I'm back with another problem!!

class Poll(models.Model):
  question = models.CharField(max_length=250)
  creator = models.CharField(max_length=100)
  pub_date = models.DateTimeField(auto_now_add=True)
  description = models.CharField(max_length=120)
  #options --> point to options database table
  #option_votes --> point to options database table

  def recent(self):
    return self.pub_date >= timezone.now() - datetime.timedelta(days=1)
  

  def __str__(self):
    return self.question

  def get_absolute_url(self):

  option = models.CharField(max_length=200)
  option_votes = models.IntegerField(default=0)

  def __str__(self):
    return self.option

Seeing that each question, or, Poll object has a choice_set, I want to order the results for any object by option_votes

Uh-oh! It looks like your message got zapped by our spam filter. We currently don't allow .txt attachments, so here are some tips to help you travel safely:

• If you attempted to send a message longer than 2000 characters, try shortening your message to fit within the character limit or use a pasting service (see below)

Hi there. I am not sure if this is directly related to web dev, but it's worth a shot asking.

I'm making a Django website for people to bulk OCR apps, So They can have multiple OCR "Jobs" which is the task of OCRing a folder contaning documents. An user can have multiple OCRs together too. Now, I have a file which does python3 ocr.py <folder-path> and I need to run it as another task whenever any user asks for it.

My questions are,

1. How to I spawn a new process to run it everytime whenever user makes a new task from the website?
2. How do I control each separate task as needed, such as kill, stop or restart whenever the user clicks on those buttons on the website
3. How do I get the logs from the process and display to the user on the site?
4. How do I keep a bound on max number of tasks that can be created in total?

Please guide me, I'm really confused about these, but I want to make this to help people do bulk OCR easily through a Intuitive web UI. Here's a image of code for the Job model for django that I made. I need to initiate tasks, control them, get logs as needed and display on website.

Is there any localstorage i can use in Django

I'm not using render(request,...)

User navigates to raw URL

But I need to retrieve data from previous view

[dusk portal]

so i'm making a e-commerce store and i want to give user option to add thier own products if they r logged in (as a a user) so how know which user added a new product to shop

noone replied

@opaque rivet

[opaque rivet]

@hardy laurel http requests are meant to be stateless, so they should contain all of the information required within the request without relying on any previous requests.

Data can be transferred as cookies, e.g.:
You can save the user's token in a cookie, then use that to retrieve account information.

You can also save formdata within the body of the request.

You can also include data within the query string of the URL.

"Local storage" is clientside only

[dense slate]

Maybe query the number of users that exist after a certain date? This is a bit more complicated since you have to tell the database what you want - unless you use some outside service.

[opaque rivet]

@dusk portal a OneToMany relationship is probably better... so one user can make multiple products

[dusk portal]

umm this time i have made whole project on my own

without any reference

i have to apply some stuff in this like

search bar with searches in whole models ( all models all types )

[terse vapor]

so like a date filter with a for loop, and use kind of like slice[i:i+30]

[dense slate]

This in Django?

[terse vapor]

flask

[dense slate]

Not sure what the query looks like in Flask, but basically just get all users, filtering for anything beyond the specific date.

[knotty musk]

ok

[lavish prism]

Hey @knotty musk!

It looks like you tried to attach a Python file - please use a code-pasting service such as https://paste.pythondiscord.com

[dense slate]

just the urls part

[knotty musk]

from django.urls import path

from . import views

urlpatters = [
path("", views.index, name="index"),
]

here

im new so keeping stuff simple lol

[dense slate]

Are you following a tutorial?

[knotty musk]

yeah

[dense slate]

instead of patterns

[knotty musk]

OH XD thank you lmaoooo

guys do you have any idea why media queries using css doesn't apply ? is there any problem django rendering them

weird thing is i made it work just as i want and then just added an mt-4 class from bootstrap and now it doesn't render im talking specifically about the column-count: 1; css property, not being read correctly

any insight will be helpful

[thorn igloo]

let me ask, are you applying column-count: 1; directly into a css file?

[next comet]

yes in static file with .css extension

[thorn igloo]

can i ask what you expect this to do or change?

[next comet]

I have 3 columns with pictures in some fancy grid display for desktop and when it's for little screens like 480 i want to make it display only 1 column

i mean i have other css as well but i think this is what doesn't display

im not sure if its a cache problem, even though i have disabled it

[thorn igloo]

you're using bootstrap to apply the grids i'm guessing?

[next comet]

yeah i have a template that is using the bootstrap but i think mainly it uses the custom css

idk how can i show you the css code in here ? if i put it in `` will it show it as a code

im new to this discord thingy 😄

[thorn igloo]

bootsrap uses css grid and flexbox for their layouts. basically they have their own set of properties you can use to change how content is structured. column-count doesn't really affect that

[violet briar]

what's the difference between WebRTC and Websockets? and why did discord choose webRTC? and when it is better to use webRTC for a chat app?

[next comet]

ooh yeah i didn't think of that haha

[faint aspen]

whats the best web framework if i wanted asp.net like class controller?

[finite ledge]

But here is some issue how can I call views function from plugin

@opaque rivet

[native tide]

Does anyone know why i can only chat numbers and not letters anymore?```php
<?php

session_start();

$text = $_POST['text'];

if(isset($_SESSION['username'])){
if (strlen($_POST['text'] == 0)){
//$_SESSION['error'] = "title is emtpy!";
echo 'Please enter text!';
die();
}
else{
$text_message = "<div class='msgln'><span class='chat-time'>".date("g:i A")."</span> <b class='user-name'>".$_SESSION['username']."</b> ".stripslashes(htmlspecialchars($text))."<br></div>";
file_put_contents("log.html", $text_message, FILE_APPEND | LOCK_EX);
}
}
?>```

[sharp basin]

I am trying to learn CSS and HTML can anybody be of any help?

[next comet]

guys do you have any good resources for django signals, im trying to understand the flow mainly pre_save and post_save how do they work and so on

[split steeple]

I can help out a bit, what do you want to know?

[sharp basin]

@split steeple

thank you for getting back to me : )

[inland oak]

brohoof

[sharp basin]

anyway i am looking to learn the basics and later advance HTML and CSS for website building

currently i have figma templates and i have to export them

and i have 0 knowledge of HTML or CSS

and i have a 10 day deadline

[inland oak]

a bit nuts

[inland oak]

https://www.oreilly.com/library/view/head-first-html/9781449324469/
this could be of help

literally from zero... you would have to walk really fast though

[sharp basin]

Thanks

anyway what about figma exportation?

[inland oak]

what about it? 😉 I saw figma only from afar

I think you can export pictures out of it

and font styles

[sharp basin]

ok

and is there a diffrence in coding or learning material

or does the book cover it all

[inland oak]

not clear question

[sharp basin]

elaborate

[inland oak]

rephrase your question in a more meaningful one

[sharp basin]

Understood

[broken mulch]

@app.route("/db")
def webdb():
  ip_address = request.remote_addr

would this give me their requesting IP address or do I have to write

def webdb(request):

[inland oak]

second

[broken mulch]

thanks

[sharp basin]

If i were to understand and grasp the knowledge to which that materialized confinment of knowledge (a book) witholds will i face any difficulty exporting a figma (or should i say ligma ) webite template.

@inland oak

[broken mulch]

btw what are cookies?

i don't understand why people need it

[inland oak]

exporting from figma is a basic skill to navigate any program, it is not related to the book.

[sharp basin]

@broken mulch a cookie file is saved to your PC, Mac, phone or tablet. It stores the website's name, and also a unique ID that represents you as a user. That way, if you go back to that website again, the website knows you've already been there before.

@inland oak

[broken mulch]

oh

[sharp basin]

how am i to grasp said skill

[opaque rivet]

Pretty sure figma gives you the css for what you've created, you just need to sort out the html then copy/paste

[split steeple]

https://htmlcheatsheet.com/css/
This can help a bit

[inland oak]

really? cool

It makes things much easier if it is so

[sharp basin]

Thanks @opaque rivet @split steeple @inland oak for your input, and assitance it is very much appreciated :))))))

[inland oak]

just use computer from day to day life, it already increases this skill
Anyway, google "exporting from figma" or something like that to find some tutorial how to do that

[sharp basin]

ok thanks

[broken mulch]

it doesn't work

TypeError: home() missing 1 required positional argument: 'request'

[inland oak]

not enough code provided to know.
you have somewhere second url with function def home perhaps

[broken mulch]

this is the start:

@app.route("/")
def home(request):

[opaque rivet]

Iirc with flask request is accessible in the function due to the decorator, it's not required as a arg

[broken mulch]

but the IP address doesn't match

[opaque rivet]

What's the issue again?

[inland oak]

oh yeah

[broken mulch]

im trying to fetch request.remote_addr

[inland oak]

request is not needed in function args

[broken mulch]

but it's the same every time

[inland oak]

from flask import request

is used instead

[broken mulch]

i request the website

im trying to return 429

[opaque rivet]

@broken mulch google is your best friend

https://stackoverflow.com/questions/12770950/flask-request-remote-addr-is-wrong-on-webfaction-and-not-showing-real-user-ip

[broken mulch]

when an ip address reached their limit

ok

does anyone know if I can connect to my website DNS using flask

or do I have to use django

[opaque rivet]

This is probably another moment where google is your best friend...

[untold hull]

can someone help me get set up with flask? i installed it and made the starter code but "flask run" says could not locate a flask application

[stable coral]

nvm could you just send your code

[untold hull]

me?

[stable coral]

Yes @untold hull

[untold hull]

from flask import Flask

app = Flask(__name__)

@app.route("/")
def hello_world():
    return "<p>Hello, world!</p>"

then on the console "set FLASK_APP=hello.py" and "flask run"

but it won't run

says "could not locate Flask application" anyone know the fix?

[elder nebula]

how do I change from django.utils import timezone to my timezone? I've added my local timezone in the settings.py, but still it shows time in UTC. in Django

oww....

[bitter thunder]

hey guys hows it going I was wondering if anyone has experience with flask-appbuilder and if I can pick their brain about it

for context I need to extend their security model to make a custom authentication function and I can't seem to find the right way to do it in the docs

[ember adder]

Django: What's the proper way to hash imported passwords with Django-import-export? I'm trying to use make_password, but it says Invalid password format or unknown hashing algorithm.

[mortal mango]

I'm getting this error in Django.

Internal Server Error: /app/oauth2/login/redirect
Traceback (most recent call last):
  File "C:\Users\Internet\AppData\Local\Programs\Python\Python38\lib\site-packages\django\core\handlers\exception.py", line 47, in inner

[19/Jul/2021 14:20:18] "GET /app/oauth2/login/redirect?code=code HTTP/1.1" 500 79016

This is the code

def discord_login_redirect(request, *args, **kwargs):
    code = request.GET.get("code")
    exchange_user = exchange_code(code)
    discord_user_auth = DiscordAuthenticationBackend.authenticate(request=request, user=exchange_user)
    login(request, discord_user_auth)
    return redirect("/app")

I believe the error is originating from login(request, discord_user_auth). Does anyone know what this error means?

[next comet]

login takes as a 2nd parameter the user

try with login(request, request.user)

[mortal mango]

discord_user_auth is the user

[next comet]

ah sorry idk the Backends yet

[mortal mango]

I have a custom authentication backend so instead of request.user I have to use discord_user_auth

[next comet]

sorry i cant be of any help ;/

unless could it be something from the redirect()

[split steeple]

that's what i'm thinking too

that or GET.get could be GET.filter

[untold hull]

"could not locate Flask application" anyone know the fix? i tried FLASK_APP=hello and flask run

[bitter thunder]

if you run it inside the folder that has the app.py file it should work

[untold hull]

there's no app.py, my file is named hello.py

that's the only file in the folder

[bitter thunder]

if its set up right you might be able to get away with python ./hello.py I guess

[untold hull]

what's weird is i got it working a moment ago

restarted the ide and back to square one

[untold hull]

does nothing

[bitter thunder]

can you show what is in the file

[dusk portal]

anyone's up

[native tide]

Hi, hope I'm not disturbing but I'm trying to put some logo credits under some details and summaries tags to be used on github readme profile but for some reason the summary doesn't end up being the summary and then it gets linked to an a tag up top

[untold hull]

from flask import Flask

app = Flask(__name__)

@app.route("/")
def hello():
    return "<p>This is the homepage.</p>"

@bitter thunder

[dusk portal]

any django dev i mean

[bitter thunder]

checking 1 sec

[native tide]

nope. Do you mind helping me though?

[dusk portal]

umm sure

[native tide]

thanks

[native tide]

This is my question

Right now the preview for my github readme looks like this

[dusk portal]

umm

[native tide]

but I want "icons sources" to be in the place of "details" as expected but it became a bullet point

[dusk portal]

ohh

umm name doens't matter btw

[native tide]

<!--- A tag with the link --->

<a href="https://www.youtube.com/channel/UC" target="_blank"><img align="center" alt="Youtube" width="48px" src="https://img.icons8.com/color/48/000000/youtube-play.png" />
</p>

<details>
  <summary>Icons sources</summary>
  <ul>
   <li><a href="https://icons8.com/icon/13441/python">Python icon by Icons8</a></li>
   <li><a href="https://icons8.com/icon/20909/html-5">Html 5 icon by Icons8</a></li>
   <li><a href="https://icons8.com/icon/21278/css3">CSS3 icon by Icons8</a></li>
   <li><a href="https://icons8.com/icon/108784/javascript">JavaScript icon by Icons8</a></li>
   <li><a href="https://icons8.com/icon/20906/git">Git icon by Icons8</a></li>
   <li><a href="https://icons8.com/icon/9OGIyU8hrxW5/- visual-studio-code-2019">Visual Studio Code 2019 icon by Icons8</a></li>
   <li><a href="https://upload.wikimedia.org/wikipedia/commons/4/4f/Icon-Vim.svg">Wikipedia</a></li>
   <li><a href="https://icons8.com/icon/19318/youtube-play-button">YouTube Play Button icon by Icons8</a></li>
   <li><a href="https://icons8.com/icon/63807/website">Website icon by Icons8</a></li>
  </ul>
</details>

[native tide]

name?

[native tide]

But yeah right here, what happens is that Icon sources will take the link from the a tag for some dang reason

No idea why

[dusk portal]

just replace details with icon sources

drom all the places

simple

oh

[native tide]

Yeah I tried that

But then

it's no longer a toggle thing

it just becomes bullet points

So I need the detail I think

If I remove all the a tags though that links to my youtube channel, or other websites, then it works fine

But then I'll only be left with the sources ofc :/

[opaque rivet]

<li><a href="https://icons8.com/icon/13441/python">Python icon by Icons8</a></li>

This creates a bullet point, and the anchor tag will redirect the user to the href link... isn't that expected behavior?

[native tide]

Yes you're right but as you can see in this image

[native tide]

this one

Icon sources is not the title of the toggle thing

[opaque rivet]

toggle thing?

[native tide]

and what happens is that it will grab the most bottom a tag that contains a link

[dusk portal]

oh bro i need a help kind of tricky

[native tide]

?

This is the full preview rn

So rn, icon sources which is the summary

[opaque rivet]

hmmm... I'm not really sure, is it possible to build your .md file solely with html?

[native tide]

will be linked to my youtube channel and if I remove the youtube icon + the youtube a tag then it'll be the website

[bitter thunder]

literally changing the name of the file from hello.py to app.py makes it work

the default for flask is app.py

[native tide]

I think so yeah

I thought it was only markdown

[untold hull]

yeah i knew that, but the problem was vscode was using powershell rather than cmd, i figured it out when i tried it on cmd and it worked, i switched vscode's terminal to cmd and now it works, thanks

[native tide]

But it seems to support html

[bitter thunder]

fair enough yeah

[opaque rivet]

maybe get rid of the <details>/<summary> tags?

[native tide]

Oh but I kinda want to hide sources

like I added it so that if someone wants to use those icon

They can just toggle the button beside "details" and see the icons

rather than have it in plain sight

Raw passwords are not stored, so there is no way to see this user’s password, but you can change the password using this form.

Personal info```

[dusk portal]

@opaque rivet haha whole para

it's saving to user db but while im doing login so it's not working but when i create user by django admin and then do login

it's workin

issh

my mind

explodes !

[opaque rivet]

well, print what the password is and inspect its format

[dusk portal]

ohh

[dusk portal]

or html

[opaque rivet]

have you googled your error

[dusk portal]

yes

ofc ihave

[untold hull]

for backend web, should i go for nodejs instead of python?

[calm plume]

You can use whichever you prefer

Both are great options

[untold hull]

i heard python isn't great for employment regarding webdev

[calm plume]

Not really

A bunch of really big companies use Netflix for their backends, such as Instagram and Netflix

[untold hull]

do they use flask or django?

[calm plume]

And I've heard that Python web dev jobs are rising, but it depends on your location

[calm plume]

Instagram uses Django with a fork of CPython called Cinder (https://github.com/facebookincubator/cinder), dunno about Netflix

[untold hull]

it probably is but it's still noticeably lower than its peers

[untold hull]

hmm

[calm plume]

But I doubt Netflix uses Flask

Hi, I'm trying to do something with django and ran into a problem ... I can't fire up my local server ...

In the end for programming jobs, companies look for people able to learn things. Yes specific positions will ask for specific stack, but I've often seen companies hiring people for their talent and willing to pay you to learn technologies (like a senior I know who was hired for a Kubernetes architect, but never did kubernetes but they know he could learn it and pay very well)

[compact glacier]

hey guys, working on django project,
in db(postgresql) i need to sync with api(), and im calling to 5000 objects in api, then adding to db.

So, what i need, compare last item in db (row in special column) with parsed items in json, OR
maybe other ways to do it by built-in methods.

i tried this:

    query = requests.get(f'https://bcschain.info/api/recent-blocks?count=3')
    checkedQuery = compareItems(query.json())
    for i in range(len(checkedQuery)):
        objects = Block.objects.create(height=checkedQuery[i]['height'],
                                       hash=checkedQuery[i]['hash'],
                                       timestamp=checkedQuery[i]['timestamp'],
                                       miner=checkedQuery[i]['miner'],
                                       transactioncount=checkedQuery[i]['transactionCount'],
                                       interval=checkedQuery[i]['interval'],
                                       size=checkedQuery[i]['size'],
                                       reward=checkedQuery[i]['reward'])


def compareItems(obj):
    try:
        last = str(Block.objects.latest('height'))
        for i in obj:
            if i['height'] == last:
                return obj[i:]
        return obj
    except:
        return obj```

but `last` is `Block object (333413)` and when comparing with `i['height']` `str(333413)` it shows FALSE.

what contains `query`
```[{'hash': 'a0642ba14658fc50a093450b2f149a1d589cd3df76414b5661fd8cb08f6727d9', 'height': 333420, 'timestamp': 1626727600, 'interval': 80, 'size': 2283, 'transactionCoun

anyone a big brain flask-appbuilder user?

[bright nimbus]

any1 have any tips on making a skill tree in html/css/js?
Im thinking of just making an image of arrows and using divs for the tree leaves

[sharp basin]

Does anybody know a website, or source where i can learn more about HTML and CSS, website building, figma exportation.

i have little to no experience in HTML or CSS, and i am willing to learn

currently i have a figma template to which i am to format it into an actual website

can anybody help me?

[opaque rivet]

codecademy for html / css, you learn by doing

[bright nimbus]

yeah i just broke another roadblock i depend on bootstrap for basically 90% of everything though

i recommend just using react or some npm way to install the stuff

[proud night]

so im working with quart and discord ipc to make a dashboard for my bot

im getting this weird error where it says the key is missing but the key is clearly there

Im on the part where im getting the guilds

This is my bot code:

@ipc.server.route()
async def get_guild(data):
    guild = bot.get_guild(data.guild_id)
    if guild is None: return None

    guild_data = {
        "name": guild.name,
        "id": guild.id,
        "prefix" : "?"
    }

    return guild_data

This is my webserver code:

@app.route("/dashboard/<int:guild_id>")
async def dashboard_server(guild_id):
    if not await discord.authorized:
        return redirect(url_for("login")) 

    guild_data = await ipc_client.request("get_guild", guild_id=guild_id)
    if guild_data is None:
        return redirect(f'https://discord.com/oauth2/authorize?&client_id={app.config["DISCORD_CLIENT_ID"]}&scope=bot&permissions=8&guild_id={guild_id}&response_type=code&redirect_uri={app.config["DISCORD_REDIRECT_URI"]}')
    return guild_data["name"]```
This is my error:

``` File "C:\Users\jacob\AppData\Local\Programs\Python\Python39\lib\site-packages\quart\app.py", line 1933, in dispatch_request

I think the dict is returning as null

If I delete a certain user or an object by using flask admin, how would I be able to add that action into the daily log(This action will be written into a .txt file)?

Like if I deleted someone with flask admin, and hoping to see this action like "user" got deleted by the admin message

[hollow minnow]

@native tide you can try to do it like this:

                <?php
                while($row = mysql_fetch_array($query)) { ?>
                 <tr class="entry">
                     <tr>
                     <td style="width: 60px;" class="text-center">'.$row['id'].'</td>
                     <td style="width: 270px;"><a style="color: red; font-weight: bold;" href="/user" target="_blank">'.$row['username'].'</a></td>
                     <td style="width: 90px;" class="text-center">0</td>
                     <td class="text-center">0</td>
                     <td class="text-center" title="Not Done">Today</td>
                 </tr>
                <?php } ?>

[native tide]

this does the same thing

[hollow minnow]

check the page source if uyou have any weird stuff maybe?

[native tide]

nothing weird

and console has no errors

[hollow minnow]

errors won't show in the console, that's only for javascript errors

Can you check the page source on the place where you'd expect the php stuff?

[native tide]

Hi, I am learning Django. And I create my own model for users(based on models.Model), I have password field, I encrypt it. And I tried to use check_password(). Idk why, but it always returns False. How to fix it? If you understand Russian language, here is StackOverFlow : https://ru.stackoverflow.com/questions/1306410/Не-работает-django-contrib-auth-hashers-check-password-всегда-возвращает-false.

[next comet]

i think you should use the form.cleaned_data['password'] instead of post['password']

[vernal moat]

#help-burrito please

[chilly mesa]

hi lads!!

for the post request i couldnt find the form-data in the chrome developer tools . you guys got any idea??

im stuck in this for a long time

[lean sentinel]

hello

may i ask somethin?

what i should do with this?

[vernal moat]

#help-cake pls

[versed python]

Looks like you have the wrong credentials setup for database access.

[lean sentinel]

if i work it on xampp its not get an error, but after i upload it to a hosting its gonna like that

[versed python]

Don't have any experience working with php, so I won't be any help

[lean sentinel]

but thank you somuch you want to answer me

[trail pebble]

Hey guys

how do you take input from a html form and save the data in mysql database using django?

[versed python]

Please do the Django tutorial, this is a part of. The basics

[trail pebble]

can u please let me know real quick i just started django two days ago

[versed python]

No, it's too long to let you know "real quick"

[elder rover]

anyone can help this

[trail pebble]

like a calendar in booking form?

[elder rover]

yup, i try to setup seem like this

[dense niche]

I'm having a hard time to come up with a catch-all function for my containerized Flask server. I've got React in another container. When I have React and server running on the same system I can go with:

@app.route("/", defaults={"path": ""})
@app.route("/<path:path>")
def index(path)
    return send_from_directory(app.static_folder, "index.html")

but ^ this is useless if my front-end is running in separate container. The app is docker-compose-managed.
Any suggestions ?

[trail pebble]

I used a calendar in booking form once I'll dm you the code hold up

[vernal moat]

Hi

how could i center text in html?

<p align="center" >Paragraph_1 Explained</p >

like this?

or with <center><p>Paragraph_1 Explained</p ><center>

[trail pebble]

this way

[vernal moat]

Okay ty

[trail pebble]

i think "<center>" tag was removed from html in an update

[vernal moat]

Ah okay

[thorn igloo]

why would you need a catch all if you're not serving the react frontend from flask?

[dense niche]

Because of Cypress automated testing. Cypress asserts "/" fine but throws 404 on all other routes. Cypress core developer told me that the catch-all function needs to be added.

[gritty cloud]

were you using ajax or html/django forms?

[dusk portal]

def search(request):
    if request.method=='POST':
        searched=request.POST.get('searched')
        x1=Product.objects.filter(title__contains=searched)
    return render(request,'index/search.html',{'x1':x1,'searched':searched})``` this works fine it works when it contains anything but i want to add more filters

like

startswith

[vernal moat]

    <nav>
        <ul>
            <li><a href="index.html">Home</a></li>
            <li><a href="skills.html">Skills</a></li>
        </ul>
    </nav>

Could someone please help?

When i go normally to the main link, i dont have /filename.html

[dense slate]

Anyone had success deploying a React and Django app to production?

I'm just looking for some advice in what things to look out for when doing so, how to structure the project, etc.

[chilly mesa]

Html django forms mate

[dense slate]

Seems that some people use django as the root where others prefer React as the root.

[gritty cloud]

In your form did you include the {% csrf_token %} tag?

[dusk portal]

help!

[dense slate]

@dusk portal You can chain filters.

objects.filter(user=user).filter(email=email).order_by('created_date') etc.

[opaque rivet]

@dense slate I use django as root with the react app in a dir called frontend. Django apps are microservices

[minor island]

In form put {% csrf_token %}.

[opaque rivet]

And for the frontend I use next.js to be able to do SSR

[dense slate]

@opaque rivet Why did you decide to have Django as the root instead of React? Since React has a build process, it feels like that should take precendence.

I have an app with django as a subfolder of Next.js.

Does it really matter in the end?

[opaque rivet]

@dense slate Don't think it matters. In my mind, the django app takes precendence because it has to render a page, so having that page in a frontend folder just makes sense...

Probably the least of your worries though

[elder nebula]

How do I make toggle between weeks and years in django urls. When no more weeks in a year, switch to another year ect.
my url patterns looks like this: path('<int:year>/<int:week_num>/', Index, name="index"),.

[opaque rivet]

I can't design frontend I'm so unimaginative

[dreamy anvil]

Has anyone here succeeded in getting a pymc3 installation to work recently? Tearing my hair out here

[elder nebula]

I tried adding 1 but I need to add some logic to it.

[dense slate]

Hmm, interesting. Since the browser hits the front end first, and the front end just need information from teh backend, that was my reasoning.

[elder nebula]

Are you a fullstack?

[dense slate]

Yea, I'm configuring the entire app.

[elder nebula]

Cool!

I do serverside and backend, also html and css, but never really learned react or any frontend framework

[opaque rivet]

@dense slate yeah just a matter of perspective

How you handling design?

[elder nebula]

me?

[opaque rivet]

Ive been using figma for some components

It's decent

[elder nebula]

I use adobe xd and figma

gimp or figma if I am on linux

I like adobe xd over figma idk why

[minor island]

If you are not web designer, it`s ok.

[dense slate]

Yea, I love the whole process.

Plus if you want to make your own software, you need to do it all.

I do prefer the front-end though.

@opaque rivet Design in what sense?

[worn hatch]

How to unite different queries results from pandas?

[elder nebula]

Totally agree. I also enjoy doing my own designs and also the backend.

I have not ever needed to use react, but what's the benefits of using react as frontend?

[dense slate]

I think mainly it is for separation of development, making it easier to have a front-end team and backend team.

But I use Next.js and some other libraries for even more benefit, like SEO, caching, etc.

Really focusing on site speed.

[elder nebula]

Can you do some extra css / element tricks with react that can't be done without?

[dense slate]

I don't know about tricks, but it's very easy to make a component and then reuse it everywhere.

That really helps.

[cedar tree]

hi does some know about trio python ?

[opaque rivet]

@dense slate design in the sense of UX and the visuals of the site

I prefer the technical side

[thorn igloo]

dude

it's displaying them alphabetically,it doesn't even affect anything

idk

isn't this something you are defining yourself?

you don't need to specify it if it's a primary key, it will auto increment when you insert the data

[terse vapor]

why is my datepicker results not saving into the sql db?

i set it to DateTime column in models

[dense slate]

@opaque rivet I'm just creating components and styling them manually to reduce any bloat in the material side of things.

It really doesn't take that much time and I feel like I have a lot more control from the beginning this way.

[opaque rivet]

Hmm, mainly color schemes I struggle with. I'll send some designs later maybe

[dense slate]

There are some good sites that basically come up with schemes for you.

Like combinations of colors that go well together.

e.g. https://coolors.co/

[lyric mason]

Im new at web dev so does anybody recommend a good course that I can use to get started?

[dense slate]

What do you want to do?

Learning Flask or Django is your best first step.

[jovial cloud]

Learn Flask first even whether you wanna use Flask or Django later cos it'll help you understand how web development works

[jovial cloud]

Flask mega-tutorial (book) by Miguel Grinberg is a good starting resource. Make sure you're familiar with the basics of python and some html before starting it

[dense slate]

What are you learning in Flask that you don't get starting with Django?

@jovial cloud

[violet briar]

what is the best db system for a graphQL api (graphene) based on your experience?

[jovial cloud]

Nothing. However, for a beginner the learning curve for flask is easier. And it helps to not get overwhelmed with information when one is just starting out

[lyric mason]

yea

[lyric mason]

i was doing django before but ill do flask instead

[dense slate]

@violet briar I think that's more a question about what kind of DB you want/need for your project. I don't think it matters much which one you choose from a graphene perspective.

[violet briar]

ah, okay, was just wondering which one handles expensive queries better

[next comet]

what ide do you use for django development

or prefer*

[dense slate]

One vote for VS Code here.

[sharp basin]

Hello everyone, today i have switched from webstorm [ a jetbrains application ] to visual studio code, i am a web developer and am need of your assitsance. What extensions should i get, any suggestions?

for html and css

[terse vapor]

@app.route("/login-admin")
def login_admin():
    auth = request.authorization 
    admin1 = db.session.query(Admin.password) 
    if auth and auth.password == admin1: 
        token = jwt.encode({'user' : 'admin'}, app.config['SECRET_KEY'])
        toknen = jsonify({'token' : token.decode('UTF-8')})
        return redirect(url_for('add_doctor', token=token))

    return make_response('Invalid!', 401, {'WWW-Authenticate' : 'Basic realm="Login Required"'})```
I'm trying to use the admin password to login to jwt auth, since, I wanted the admin can change their password when ever they want in frontend, however, after running the code, when I submit the input, it redirect me back to the same page, like it just refreshed it. So is there any where i did wrong? 😅

[dense slate]

What's the form look like on the frontend?

[terse vapor]

its like a littly pop-up window that vallow me to enter username and password

[ruby turtle]

hello guys
i have a problem

i can't import speedtest

any can u help me 😄

[inner badge]

Did you install it?

pip install speedtest-cli

[ruby turtle]

i don't know how install it

[inner badge]

[ruby turtle]

look

[terse vapor]

no

type "pip install speedtest-cli" in terminal

like behind the >

[terse vapor]

but im still not sure why it isnt working

[dense slate]

Was asking you to share the code.

Is there javascript involved?

[terse vapor]

no java script involved

def token_required(f):
    @wraps(f)
    def decorated(*args, **kwargs):
        token = request.args.get('token') 

        if not token:
            return jsonify({'message' : 'Token is missing!'}), 403

        try: 
            data = jwt.decode(token, app.config['SECRET_KEY'])
        except:
            return jsonify({'message' : 'Token is invalid!'}), 403

        return f(*args, **kwargs)

    return decorated

this is all the code for the jwt auth

[dense slate]

Where is your frontend code.

The actual form on the site.

[terse vapor]

I dont have a frontend code for this

I inputed the link address and this is what came up to me

so the only front end is for the admin model which transfer its data from a flask form than to route.py and too database

[next comet]

"live server" i think it was called, also activate auto save, "prettier" (for formatting the code but its just visual stuff and personal preference); also learn the shortcuts like div.somename will make div tag with class='somename' or ul > li * 3 will make ul tag with 3 li inside it

[dusk portal]

oh

[native tide]

does anyone know how to do somehting like this

with

<select>
<option> aaa bb c </option>
</select>

aka have "subsections" of each option element

[thorn igloo]

use column-count in css

[native tide]

would the column-count property go in select or option? and how would i use it?

[thorn igloo]

right, i saw that you wrote

<option> aaa bb c </option>

so if it's all on one line column-count will devide the element and spread the content into even columns, but that might not be what you want so you can instead use flexbox or grid

i'm not familiar with grid but i'll show you an idea of how you can achieve it with flexbox

actually, option wont work for this

that's not how it works

that will only produce a drop down list

[native tide]

?

i got my current html to look like this

[thorn igloo]

define another option and you'll see what i mean

[native tide]

but want it to be like this

is there no way?

[thorn igloo]

let me check something

[native tide]

Hello so I did a post request using js and the post works just fine

function deleteApplication(application) {
    fetch("/deleteapp", {
        method: "POST", 
        body: JSON.stringify(application)
      }).then(res => {
        console.log("Request complete! response:", res, application);
      });
}```
but I am struggling to get it on the python side I am trying to get rid of the b'' surrounding it when printing
```py
@app.route("/deleteapp", methods = ['POST'])
async def deleteapp():
    text = await request.get_data()
    print(text)
    return text```
Console: `b'"TEST"'`
I am using quart for the web development.

No errors I just need to get rid of the b''

what do I need to do?

[thorn igloo]

so i guess it is possible, let me show you with flexbo

[native tide]

try a text.decode("utf-8")

aight

[thorn igloo]

so you'll have a structure like this:

<option>
  <div class="options">
      <span>a</span>
      <span>b</span>
      <span>c</span>
  </div>
</option>

then in your css

.options {
  display: flex;
  flex-direction: row:
  justify-content: space-between;
}

[native tide]

iirc you can't put extra tags in <opion> tags

[thorn igloo]

i tested it and the extra tags worked

[native tide]

hmm let me test

<style>
.options {
  display: flex;
  flex-direction: row:
  justify-content: space-between;
}
</style>

<select multiple="" size="20" style="width: 300px">
    <option>
        <div class="options">
            <span>a</span>
            <span>b</span>
            <span>c</span>
        </div>
    </option>
</select>```

when i copy/paste this into the browser i get

<html><head><style>
.options {
  display: flex;
  flex-direction: row:
  justify-content: space-between;
}
</style>

</head><body><select multiple="" size="20" style="width: 300px">
    <option>
        
            a
            b
            c
        
    </option>
</select>
</body></html>```

completely removing the inner tags :I

[thorn igloo]

right, just saw it

i guess it's impossible

[native tide]

yh rip

[thorn igloo]

to do it that way

Hi
how can i set a gradient background?
<style>
.my_bg {
height: 100%;
background-color: blue; /* For browsers that do not support gradients */
background-image: linear-gradient(45deg, #FFFFFF, rgb(0, 157, 255));
}
</style>
I tried this
im not sure what to do to show it as the background
<div class="my_bg"></div>

[opaque rivet]

hey guys, was reading a blog and came across this:

A queryset in Django represents a number of rows in the database, optionally filtered by a query. For example, the following code represents all people in the database whose first name is ‘Dave’:

person_set = Person.objects.filter(first_name="Dave")

The above code doesn’t run any database queries. You can can take the person_set and apply additional filters, or pass it to a function, and nothing will be sent to the database.

How does that code not run any database queries? Doesn't this run something like this in SQL under the hood?

SELECT * FROM Person
WHERE first_name = 'Dave';

[inland oak]

yes, you can essentially even see the SQL code under the hood

person_set = Person.objects.filter(first_name="Dave")
print(str(person_set.query))

[opaque rivet]

oh cool - that will come in handy. But then doesn't that contradict the statement "The above code doesn’t run any database queries"?

I'm unsure what's meant by that.

[inland oak]

well... I think they mean that...

when you just write
Person.objects.filter(first_name="Dave") it is not running query immediately
because it allows you to chain your ORM code in this way
Person.objects.filter(first_name="Dave").filter(second_name="Lalala").filter(third_param="lalala")

only when the phrase is finished

then it runs

combining all functions you requested in chain into one SQL query

[opaque rivet]

oh... I misread, well then it does run a database query once its called

[inland oak]

well yeah

[gaunt charm]

is someone here good at django? i need help

[versed python]

. it does run a database query once its evaluated

[dusk portal]

anyone's up

ohk im stuck

[dusk portal]

@opaque rivet hey

def search(request):
    if request.method=='POST':
        searched=request.POST.get('searched')
        x1=Product.objects.filter(title__icontains=searched)
        if not x1:
            x2=User.objects.get(username__icontains=searched)  
    return render(request,'index/search.html',{'searched':searched,'x1':x1,'x2':x2})```

{% if searched %}
<center>
<p>You searched {{searched}}..</p>
</center>
{% else %}
<p> U didn't searched anything..</p>
{% endif %}```

{% if x1 %}
#all the stuff
{% else %}
<p> No result found for {{searched}}</p>
{% endif %}```

{% if x2 %}
<strong>Users</strong>
<ul>
  <li>{{x2.username}}</li>
</ul>
{% endif %}```

so here i want that it should search by title and if not any post come by that title and if any User is with that related username (like a restuarent have named as pizza hut so when i write pizza , so item pizza also comes + the restuarent (username)

so i want to filter that

so my user function is working fine

by 1 my product is SPACE

works fine!!!

so i have item called space and i wanted to render it it comes

when i enter xyz (with is not in both user and title)

[dense slate]

So what's your question.

Btw I would probably instead pass each variable individually to the function and just use them as you need them. Something like:

def search(request, **kwargs):
  if request.method=='POST':
    if kwargs['title']:
      result=Product.objects.filter(title__icontains=title)
    else if kwargs['username']:
      result=Product.objects.filter(username__icontains=username)
  
  return render(request,'index/search.html',{'result': result})

there's probably an even more efficient way

or else you'll have a separate context returned for each condition which can get messy quickly. @dusk portal

Hello guys. I badly need help, I need to do a webscraping. To give you details, They gave me a zip folder to extract a file, inside that extracted file was 3 folders with python codes, they told me to use beautifulsoup and pip. so after extracting it, I dont know the next thing to do. here is the screenshot. the notepad was the extracted file with codes then the other side is a jupyter notebook which I prefer to use. Unfortunately, it is not working

[dense slate]

From the error, you need run_Geofence in your environment.

I don't know if it's a library or just another file.

What's get_services look like?

@login_required
def order(request):

    zipcode=models.IntegerField(default=0)

    def __str__(self):
        return  self.name``` am i going correct?

how can i render that user on html umm

[gentle jasper]

Hi, can you tell me if it is ok the way I did it?https://github.com/SoundB1/ToDo-Django

[opaque rivet]

<div class=verticalnav> the classname has to be in quotation marks

[opaque rivet]

looks good to me...

[next comet]

if you want to have a property or something from the view order you need to put that in a context = {'name':variable_you_want} and pass it as a third argument to the render function; thus way you can access that variable_you_want with the DTL syntax like {{name}} in the html template

im not sure if thats what you are looking for but, at first look that is what is missing in your order view

[opaque rivet]

also:

name=request.POST.get('name')
        email=request.POST.get('email')
        author=request.user
        phone_no=request.POST.get('phone_no')
        address=request.POST.get('address')
        zipcode=request.POST.get('zipcode')
        entry=Order(name=name,email=email,author=author,phone_no=phone_no,address=address,zipcode=zipcode)

all of this can be simplified into

entry=Order(**request.POST)

@dusk portal

[dense slate]

does the ** just apply all the variables?

like ...rest or ...props in js?

[outer apex]

Similar! JS's spread operator works for almost all iterable objects. Python however has two unpacking keywords: * and **. The latter is for dict whereas the former is for non-dict iterable of objects (e.g. lists, sets).

so.....i am working on porting my desktop GUI apps over to web apps. right now i am just building my design but am starting to look at frameworks. I am looking at Django and flask. any others i should look at?

background: I have done some flask work but it always seems unintuitive to have it served in a production level. I have mainly written scripts and desktop gui apps in python, but, due to some circumstances (thanks COVID), so many remote working people has caused my pyinstaller'd apps to take WAY too long to open (30+ minutes). I am also working on consolidating m apps so you only have to go to one site to get to all of my apps.

Queston: What framework would you recommend?

[eternal blade]

I would recommend Django

It may be hard at first but it will become easier as you use it

[dusk portal]

        author=request.user
``` why this and this is not using post request

@opaque rivet

[eternal blade]

What do you mean?

It returns the logged in user who is making the request

[real crest]

git config --global user.name "Emma Paris" $ git config --global user.email "[e-mail]"

[deft shore]

how can I generate html forms from the admin panel? I want to be able to add custom fields and things like that.

[late creek]

look at Pyramid https://trypyramid.com

[barren pagoda]

hey everyone i'm new to django and i'm trying to wrap my head around the apps business

i get that each app is sort of meant to be a delegate for one business domain or context

but i'm not sure i understand how it's meant to be used in practice

because, as far as i googled, you can't start django and have multiple apps running simultaneously

so i'm very confused how you're supposed to manage this

[late creek]

You can, you need to use gunicorn and preferably for me nginx for the reverse proxy to Django, then you can specify multiple domains that point to different apps in nginx

[barren pagoda]

i was given a small spec of a project with two apps and they want me to run each app as its own microservice, each on a particular port. initially i just worked on each app individually and made sure they work, now i'm struggling to find how i can run them both since one app's model contains a foreign key for the other app's model

[barren pagoda]

ok this helps, now i have a starting point to work with

thanks

Hey, im having problem with the Static folder. i always get errros like "Not found" or "HTTP 404 "

[next comet]

do you load static in your html

and have you put the STATICFILES_DIRS = ['BASE_DIR / 'static'] in your settings

also you need to load it with the {% load static %} in your html template and in the <link> tag the href should look like this {% static %}

and the url to the file you want to load from the static folder

[next comet]

i wrote this by memory so there could be mistakes in the variable names, so check it in the django doc to be sure

[wise igloo]

How do I build a button that on click sends data to my Postgres database? This is after the page has received a POST Form with a url that is used to scrape a certain website

I would rather not use a second (hidden) form or ajax/jquery for this, as these seem a bit hacky approaches

I wrote this question more extensively in #help-coconut but the channel was closed before someone could answer my question

[versed python]

You can catch the click event on the button, and then execute the post request inside it

[wise igloo]

but this would make for a second post request on the same page

and I already have an if request == POST section in this particular view for the scraping part

[versed python]

How exactly do you plan to save data to postgres?

Do exactly that inside the function

[wise igloo]

but would this be a js function?

[versed python]

Yeah

Can't be done without

[wise igloo]

Ok

[versed python]

Since you want non browser behavior

[wise igloo]

So then I have to connect to my database from both Python and JavaScript in this project

[versed python]

That sounds like a bad idea

[wise igloo]

That's what I thought

[versed python]

If your backend already connects to the database, send the request there

And the backend can do the rest

[wise igloo]

yeah but this is where I'm stuck

How do I do that in the backend then

[versed python]

What is your backend?

Django?

[wise igloo]

Django

I know how to add data to my db from Django

[versed python]

Create a new function to handle this

[wise igloo]

but not in this particular case

how would I call that function?

[versed python]

I meant

Just create a view

An api view

And send a request using window.fetch in the Javascript part

[wise igloo]

Hm

Ok that sounds like a new approach, I'll take a look into that

Thank you very much!

[mint hedge]

heard of that one too. you have any experience with it? does it come packaged with a production ready way to serve the site?
