@orchid hamlet i dont have the exact code right now but its something like that (as i remember it lol)

----- flask code -------
@app.route("/start")

this executes func1()

def start():
func1(param1, param2)
return render_template("index.html")

@app.route("/download")

this is for downloading a file when the button is clicked

def download():
file = func2()
return send_file(file)

-------python code (backend) -----
global_var = ""
def func1(k8s, name):
global global_var
global_var = f'{name}{date.now()}.pcap'

def func2():
global global_var
file = global_var
return file

[orchid hamlet]

ok so you want to get the value of the global variable?

i.e download the file

[bleak adder]

Yes ... if i call func2() in the /start route it works fine but this doesnt work in separate routes

[orchid hamlet]

did you declare the global_var

variable

ok yes you did

[bleak adder]

Yes # global_var = ""

indeed, func2() returns a blank global_var

is there a way to store the value returned by func1() for later use when i call func2()?

[orchid hamlet]

yes it is

though i think you need to use sql

for string the val of func2() you might require sql

if you cannot manage with the global var

sqlite3 comes preinstalled with python so yes you can

[bleak adder]

i'll try it if it doesnt complicate things 😅

[orchid hamlet]

yes i will just give you the formatted code

[hexed current]

Hello

guys

I need help with something

I'm using selenium and python and i want to submit a captcha token

but I can do so because there is no submit button

I tried making a button

but it didn't really do anythig

[orchid hamlet]

hey i figured out another way

this will only use 2 lines

[bleak adder]

Without sql ?

[orchid hamlet]

@app.route("/start")
func_1_val = str()
# this executes func1()
def start():
    global func_1_val
    func_1_val = func1(param1, param2)
    return render_template("index.html")

@app.route("/download")
# this is for downloading a file when the button is clicked
def download():
    file = func2()
    return send_file(file)

-------python code (backend) -----
global_var = ""
def func1(k8s, name):
    global global_var
    global_var = f'{name}{date.now()}.pcap'
    return global_var

def func2():
    global global_var
    file = global_var
    return file```

yes that is done

@bleak adder

@bleak adder

[bleak adder]

Thank you @orchid hamlet i will try it

[orchid hamlet]

I just stored the value by returning func1 to func_1_val

[bleak adder]

i hope it will work when i call func2() 🤞

[orchid hamlet]

oh yes the value is stored in func_1_val, so edit your code accordingly

[bleak adder]

Alright ... thank you 😋

I'm building a form in Flask using Flask-WTF and wtforms. Everything works except for my BooleanFields, which always return false -even when checked on the front end.

In my form class, I just have them listed as:

field_name = BooleanField('field_label')

Am I missing something?

[orchid hamlet]

why the extra ' in field label for?

[main kayak]

Typo

[orchid hamlet]

can you send the code?

[main kayak]

Standby

Sorry, its too long - one sec.

Ugh lol, nevermind. I figured it out. Copying the relevant jinja code made me spot the issue.

[orchid hamlet]

no problem.

[main kayak]

Thats the problem with coding at 2 in the morning.

[orchid hamlet]

whats the issue btw

was*

[main kayak]

I had value = "" as an attribute of each boolean field in my jinja template.

So I guess it was forcing them all to be false.

removed that, and now it works as expected.

Not sure why I put that in there to begin with.

[orchid hamlet]

oh so the value kind of reseted

[main kayak]

¯_(ツ)_/¯

[mystic wyvern]

It's Impossible in the model bcz you have to migrate everytime anyone logged in or logout, then the solution should be in the view, your author field should be updated everytime you go to this form page by enter the logged in user

[stable bear]

{% extends "layout.html" %} 
{% block title %}About{% endblock %}
{% block body %} 
<img src="about.jpg" alt="About" width="500" height="600">
{% endblock %}

This is my HTML code to display an image. However, the image does not show, and instead the alt text does.

[obtuse robin]

the image src is incorrect then

Hi, I am integrating mysql and flask and I'm trying to search for a matching substring in a mysql row in my flask web api.

I got this code in another file listing.py

 def getTravelPackageBySubstring(cls,substring):
     try:
         dbConn = DatabasePool.getConnection()
         db_Info = dbConn.connection_id
         print(f"Connected to {db_Info}");
         cursor = dbConn.cursor(dictionary=True)
         sql = "SELECT * from `travel listing` where description or country LIKE '%",(substring),'%"'
         substring=cursor.execute(sql,(substring,))
         substring = cursor.fetchall()
         return substring
     finally: 
         dbConn.close()
         print ("release connection")

How can I get it to run in app.py?

I tried

@app.route('/listing/<string:substring>')
def getTravelPackageBySubstring(substring):
    try:
        jsonListing=TravelPackage.getTravelPackageBySubstring(substring)
        jsonListing={"Travel Listing":jsonListing}
        return jsonify(jsonListing)
    except Exception as err:
        print (err)
        return {},500

and it gives an error ''tuple' object has no attribute 'encode'

[prisma oracle]

have u figured this out?
i was doing the same thing rn

[native tide]

Could be what you're passing to cursor.execute - Is the first argument (the variable sql) the type string or tuple?

@tribal onyx

Looks like the variable sql is of type tuple - I don't know if it should be.

>>> substring='foobar'
>>> sql = "SELECT * from `travel listing` where description or country LIKE '%",(substring),'%"'
>>> print(sql)
("SELECT * from `travel listing` where description or country LIKE '%", 'foobar', '%"')

The reason it probably errors with the message tuple object has no attribute 'encode' is the method cursor.execute calls encode(...) on the first argument you pass it, which is of type tuple and not type string

That line should use the + operator to concatenate those strings (Actually this is vulnerable to SQL Injection, so...you may want to use prepared statements) instead of using , to make sure the type is string and not tuple

is this as simple as adding django_app to ALLOWED_HOSTS lol

that did not seem to work

https://stackoverflow.com/questions/33097700/django-error-external-ip-invalid-http-host-header-domain-com this might help

nah, not really i already had all that stuff set

the nginx config is working, it django that seems to not like this.

I wish that django had built in configs to understand, "This is a staging server. Just go with it."

[boreal minnow]

hey, could someone please explain unit testing mocking to me?
im learning nestjs rn, and one thing i noted is that most tests in the most popular test repo (https://github.com/jmcdo29/testing-nestjs) use mock functions for testing
isn't that approach objectively wrong? since we always know what mock function returns, the test is always gonna pass, while the actual controller logic is not tested at all

let's say we have mock func of findall returning array 1, 2, 3
then we test this function for element at index 2 being 3, and ofc, test passes
but actual logic used in controller is not tested at all this way
what's the point of mocking then?

[worthy lake]

the solution to my problem if anyone cares? remove underscores in nginx.conf... django_app becomes djangoapp; then it has to be added to ALLOWED_HOSTS

i created a news model that admin can create news and show it on pages now each user can comment on posts so i created comment form inherited the modelForm
now if i display my form it shows the user_id and news_id which is supposedly filled up automatically depending on the post selected and currently logged in user

or should i use forms.Form?

how to solve this errror

[native tide]

The kms_driven key does not exist.

https://www.toptal.com/developers/hastebin/laxilumiju.py

Use the .get(key, default) method instead to provide a default value when the key is not found. And if you're sure the key must exist, then it's probably missing. Debug the part where you're adding parameters to your GET request

[sudden sierra]

Filling form fields automatically should be handled by the views. You can access the current user using request.user and you should get the news instance using

news_obj = News.objects.get(id=id)

If you pass the id as a path parameter

Hi, I built my project using Angular, Django and PostgreSQL
I have never deployed my projects before
I want to deploy on Heroku or AWS
Any tutorials or documentations please?

[lapis spear]

something like this?

and in my template i just remove the 2 fields as it will be filled on the views.py ?

[lapis spear]

or should i just not use modelForms for this? its just the comment model

[sudden sierra]

Maybe you should use the initial argument when creating the form instance, and the pass the user and news like this

user_id = request.user
news_id = id # or maybe you need the object, not the id

form = CommentForm(initial={"user_id": user_id, "news_id": news_id})

[sudden sierra]

It's fine to use ModelForm

i have made a webpage which shows the youtube videos based on the query result using the youtube data api

how can i implement that in django?

Dumb way: Client side javascript REST API calls in a loop to your Django Rest Framework endpoint
Smart way: Web sockets (Feel free to check Django Channels in addition for Django with web sockets flavour)

[frank shoal]

I'm adopting lodash into my project. Would this be the correct way to convert this function? ```ts
const rows = {} as Record<string, string[]>;
for (const item of selectedItems) {
const [name, rack] = splitLabRow(item);
if (!(name in rows)) {
rows[name] = [];
}
rows[name].push(rack);
}
return Object.entries(rows);

to
```ts
  return _.chain(selectedItems)
    .map(splitLabRow)
    .groupBy(0)
    .mapValues((v) => _.map(v, 1))
    .toPairs()
    .value();

[agile pier]

which one is the easy way cause i m on a deadline here

also pls share any yt video or resource if any..

[inland oak]

dumb way is easiest

though it will require from you some level of Javascript understanding how to do it 🤔

[nova vessel]

Hey I’m on windows 10. And vscode isn’t recognizing pipenv

Working on a project using Django and I can’t get venv setup

[frank shoal]

Is pipenv installed via pip install --user pipenv?

maybe you're using pipx?

[nova vessel]

Yup did that and went in manually and into environment variables and set it up

Still not working

[nova vessel]

Possibly, how can I switch?

[frank shoal]

set your path and restarted your shell?

[nova vessel]

Yup did that too

[frank shoal]

just log off and back in

[nova vessel]

Did that too 😂

[frank shoal]

are you using cmd bash or powershell?

[nova vessel]

Power shell

[frank shoal]

run get-command pipenv

[nova vessel]

Okay

Will do after lunch

[frank shoal]

if it can't find it, double check the path via $Env:Path

If all else fails, use pipx. https://pypa.github.io/pipx/

It installs your applications to ~/.local/bin

[nova vessel]

Then source /bin/local/activate to set venv right?

[frank shoal]

no, that's handled by pipenv

[nova vessel]

Oh

[frank shoal]

It's been a while since I used pipenv (I use poetry now), but I think it's just pipenv install <package> then pipenv run yourcommand

there may also be a pipenv shell command.

[nova vessel]

Okay bet I’ll try that

[agile pier]

do u have a example code?

[nova vessel]

@frank shoal hey got pipenv to work, do you have the documentation site for it>

[frank shoal]

https://docs.pipenv.org/

.. why is the site in cursive?

[nova vessel]

its normal for me...

[frank shoal]

This isn't cursive for you?

[nova vessel]

Nope

You broke the website

[frank shoal]

I wonder why it's different in firefox

btw, this is the actual docs page.

The old one was from when it wasn't part of pypa

It is for me

firefox?

I think I had two models instead

Question: let's say I have 3 models: user, country, and region.

Each user has a region and a country, and each region has a country.

How can I make it so that when either I'm in my admin panel and adding new users, or users are registering on the website, I/they only get to see the regions depending on the country they've selected(Since I wouldn't want to show them regions belong to other countries)?

[glacial wigeon]

Exactly when does heroku delete user uploaded files from its ephemeral storage? I'm new to webdev,
making a django webapp that takes user uploaded files(text files; pdf,docx,epub etc) and does some processing on it and shows an output in the form of a plotly graph. I am fine with heroku deleting the file after I'm done displaying the graph to the end user. Will heroku fit these specifications?

[native tide]

    href="{{ url_for('static', path='styles/index.css') }}"
  File "Z:\Code\Friends Computer\lib\site-packages\starlette\templating.py", line 72, in url_for

    raise KeyError(key)
KeyError: 'request'```

jinja2 giving this err

fastapi

[agile pier]

i think Heroku doesn't deal with user uploaded files
for that u need to integrate AWS

https://devcenter.heroku.com/articles/s3-upload-node

[glacial wigeon]

Oh? I was under the impression that it does
https://stackoverflow.com/questions/15637018/uploading-files-on-heroku

[glacial wigeon]

I think this is for people who want to store the files long term

I don't care if it gets deleted in 5mins or whenever the dyno restarts

https://devcenter.heroku.com/articles/dynos#isolation-and-security according to this the dyno restarts when we push new changes or in a fixed time every day whichever is earlier

Does anyone here use FastAPI and the companion SQLModel? I've done an app with them and it's all fine and great until I need to delete lots of rows. I can't figure out how to do a "delete from x where something something".

I can select all the objects that should be deleted and could probably do a session.delete(obj) in a loop, but that sounds beyond daft.

how do I change the format of 2022-06-28T05:44:45Z in the django template?

hey

i was wondering if there were any quick web libraries to display some statistics?

i have a project which tracks individual stocks and being able to show their current prices, charts, etc on a simple list web UI would be helpful

[iron magnet]

I asked here because my searches turned up nothing. The session object doesn’t work like the one in SQLAlchemy.

[novel stream]

But did you installed it in your virtualenv?

[novel stream]

I think this is what you need: https://docs.djangoproject.com/en/4.0/ref/templates/builtins/#date

[novel stream]

well I did a quick search here and found this that might help you https://stackoverflow.com/a/53501451/3716354

[manic crane]

im not using virtualenv

[inland oak]

It sounds like regular used Data Science tools

panda is used together with plot something libs
They will draw result in picture format, which you can show in web
You could check advices from people in #data-science-and-ml , or just checking stuff used by people in tutorials at https://kaggle.com
Or actually it can be googled as panda plot, https://pandas.pydata.org/docs/user_guide/visualization.html, there are libs for 2D and for 3D visualizations

[novel stream]

Docker then?

[manic crane]

no just normal terminal

[novel stream]

well I would strongly advise you to use a virtualenv then. Create one with python -m venv .venv it will create a directory called .venv where you can activate by source .venv/bin/activate then inside that env you can install all your packages. The problem your facing is really common when you're installing packages globally

[manic crane]

hmmm ill try thanks

[iron magnet]

But that’s raw SQLAlchemy. I have an SQLModel session.

[manic crane]

i got this error => ```Error: Command '['/Users//Desktop/occupy/backend/.venv/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.````

i tried installing venv with sudo and got this => sudo: apt-get: command not found

[novel stream]

Because it seems that you're already inside a .venv

[manic crane]

oh really

[novel stream]

If you have python3 you don't need to install venv, it already comes with Python

[manic crane]

oh wondeful

[novel stream]

run the following: which python

[manic crane]

/usr/bin/python

im using python3 because for every command i have to run python3 like python3 manage.py runserver

[novel stream]

That's weird. What is your python version? and which OS you're using (windows I suppose)

[manic crane]

macbook

Python 2.7.16

[novel stream]

You might also have python3 installed. Try the following: python3 -m venv .venv - if my assumption is correct this would create the .venv folder inside the directory you're in

[manic crane]

this is what i get when i install simplejwt

[novel stream]

because this is installed in your global

after creating the .venv you need to activate it and then install your dependencies

[manic crane]

hmmm i do have venv folder but still got the same error

[lapis spear]

yo ive been stuck here help me 😅
i am getting the "form is invalid" output on my terminal meaning i failed the form.is_valid check how to debug that?

[novel stream]

did you activate it? and then installed there your dependencies?

[lapis spear]

how do it know why is my form.is_valid() failed?

[manic crane]

no ive not activated it ill check how to do it

[novel stream]

Might be good to have an else where you do form = CommentForm() so that if your form fail for some reason it will get back to your templates and then your templates should render the errors

[novel stream]

You can run source .venv/bin/activate

[lapis spear]

like this?
but how do i print errors? is in on templates? or terminal?

[novel stream]

No, the else should be in the same level as the first if

the if request.method == 'POST'

[manic crane]

bash: .venv/bin/activate: No such file or directory

[novel stream]

can we go to a video room so that you can share your screen?

I'm in Live-Coding

[lapis spear]

this?
but it will only run if i dont have request.method = 'POST' right?
how will the else statement be triggered? was it if my form is not valid?

[manic crane]

yes is der not an extension for that

i think u can only do that for html and css

[novel stream]

if your form is not valid it won't pass to the else and will go directly be passed to the context variable

[novel stream]

can you run then ls -la in your current dir and show here the results?

[manic crane]

ill send in private chat

[lapis spear]

then what is the reason for the else statement? 😅 sorry i just dont get the flow of what i am doing now im confused hahaha

[novel stream]

the else statement is basically saying: if this is not a POST method, let's instantiate an empty form and send it to the context to be rendered in the template

[lapis spear]

oh right i get it now i see

but i still got my main problem my form is invalid

this is my model

and this is my modelform

since user and news_id should be automaticall filled based on the id and currently logged in user i filled it on view by the initial={} argument and the only thing i am getting on the form is the comment field

i feel like this is a simple problem with simple solution but i still cant figure it out im at dark with this django hahaha😅

[novel stream]

I think then the problem is that you're creating two different forms at once. The correct approach would be: form = CommentForm(request.POST, initials={"user_id": user.id, "news_id": news.id})

[lapis spear]

yeah youre right
i did your revision but i still get the form is invalid output on my terminal means i failed the form.is_valid() check

[novel stream]

Try adding a breakpoint() before the form.is_valid() line. When the code hits this point it will stop the server there. Then you will be able to see what is happening by printing the values

[lapis spear]

i used the first answer here and now i am seeing this error messages on my terminal https://stackoverflow.com/questions/20723646/form-is-valid-returns-false-django

[novel stream]

When the server stops there you can do the following:

[lapis spear]

its seems my form is empty

[lapis spear]

yes how can i check form values?

[novel stream]

print(form.is_valid())
print(form.errors)

it will show you what are the errors in your forms

[lapis spear]

there it is my form are empty

but when i print the news and user variables i got values of them

or do i need the ids? because they are foriegn keys?

[novel stream]

yes you don't pass the object, you need to pass the IDs

[lapis spear]

its the same even i pass the ids on the forms same form.errors

this is how the code looks like now

btw how do i stop that breakpoint()?

[novel stream]

to stop it or just go you press c and enter

[lapis spear]

oh i got it nice this is a handy tool e h

anyways back to my horror story

why is my forms becoming empty? the code shows that they have values but they are infact empty

[novel stream]

yeah I'm a little bit confused 🤔

can you run again and then print the value of request.POST?

[main sorrel]

const getData = new XMLHttpRequest
getData.open("GET","https://api.ipify.org?format=json");
getData.send();
ipData = getData.responseType = 'json';
document.getElementById("tag1").innerHTML = ipData

umm anyone know why this wont work

im a bit new to requests in javascript so

[lapis spear]

i am getting the comment value on post
haha what is happening here am i hunted?

[frank shoal]

You need to read the response in a callback.

and call the constructor. new XMLHttpRequest()

https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/Using_XMLHttpRequest

though you should prefer using the fetch api

function onSuccess() {
  document.getElementById("tag1").innerHTML = this.responseText
}
const xhr = new XMLHttpRequest()
xhr.addEventListener("load", onSuccess);
xhr.open("GET", ...)
xhr.send()

// vs

fetch(...)
  .then((data) => data.text())
  .then((data) => {
    document.getElementById("tag1").innerHTML = data
  })

[novel stream]

can you also show your templates as well?

[novel stream]

actually that now I'm seeing your model you really should pass the objects not the ids form = CommentForm(request.POST, initials={"user_id": user, "news_id": news})

[lapis spear]

here is my template simple render of the form

[novel stream]

I think you should have something like {{ commentForm.as_p }} because the way it is right now you're only rendering one field: the comment

[lapis spear]

but it shows the fields that should be hidden and filled automatically

[novel stream]

Hmmm so I think you should update your model form to make those fields rendered and then continue to pass the initial to then. Check here: https://stackoverflow.com/a/23463004/3716354

[lapis spear]

you mean the widgets?
btw is this a correct approach? or there is a better way to get this comment from user?

[novel stream]

if you have fields that you don't want to show to the user in the form, you have either two options:

1. override these fields in your ModelForm and make them not required. Then pass the values from the initial option (you might need to also override the ModelForm __init__ to set these values. With this when you submit the form again your form won't complain saying that some fields are missing
2. In your form you use the widget approach to make them hidden so that only the comment field will appear in the frontend and then set the initial values in your form

[frank shoal]

In lodash, is there a shorthand for this? ```js
_.map(x, (id) => object[id])

I managed to do _.partial(_.get, object)

[lapis spear]

do have link for example on option 1?
also on option 2 is it safe like the hidden fields are hidden even on htmL? you know thos inspect element stuff

[novel stream]

You can see some examples here: https://docs.djangoproject.com/en/4.0/ref/forms/fields/#core-field-arguments for option 1

Following with something like this https://stackoverflow.com/a/604325/3716354 and something like this to set the default values: https://stackoverflow.com/a/51162353/3716354

[lapis spear]

i think this option 1 is a more appropriate way of doing things?

[novel stream]

Probably, yes

[lapis spear]

widget thing can be altered on html by browser

but i dont understand this option one haha imma rest for now see you again next time sir thank you @novel stream

How to make migrations in Django after deleting the migrations and pycache dirs and after flushing the db? Tried migrate and makemigrations and it keeps saying nothing to do

Goddamnit, why it has to be always so rtarded in django with all the migrations stuff

[golden bone]

hmm, so you did everything described in Scenario 1 here?: https://simpleisbetterthancomplex.com/tutorial/2016/07/26/how-to-reset-migrations.html

[copper juniper]

Yeah, and I'm back to where I was before deleting those dirs, now i got this annoying err ```
File "C:\Users\ansga\Desktop\SHOP2\django\env\lib\site-packages\django\db\backends\sqlite3\base.py", line 477, in execute
return Database.Cursor.execute(self, query, params)
django.db.utils.OperationalError: no such column: store_product.safe_name

So its like I got this in my models, but migrations are not following it, and there is no such record in db yet, weird thing

Oh, my model was bad, I've noticed it after fixing manually the migrations that I'm putting the raw bytes into a CharField, I'm dumb, move along nothing happened here

hi guys, I'm using SQLAlchemy and I'm trying to delete a row after it's been updated like so:

@event.listens_for(Emails, 'after_update')
def delete_retrieved_email(mapper, connection, target):
    # If email row has been retrieved, it has been saved in the client's local storage. We now delete it off the server.
    if target.retrieved:
        with Session(engine) as session_:
            session_.delete(target)
            session_.commit()

The issue is that the row is not being deleted. Any help please?

[native tide]

What's the difference between:

class customUser(AbstractUser):
pass

and

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)

?

[proper hinge]

The former is meant to be a replacement of the user model, so that setting needs to be updated, and it will require a potentially difficult migration if you're not doing this at the start of your project.

The latter creates a separate table with a FK to the user table

At a higher level, I think the choice comes down to a semantic difference.

Like, if you have data associated with a user that's only relevant/useful in certain contexts, then the OneToOne approach may be more suited to that.

Though when you start your project, it's good practice anyway to subclass AbstractUser and create a custom user model (in case you need it in the future)

     headers: {
         'X-CSRFToken': csrftoken
     },
     ...

[hushed crow]

is django just a debugger or full website builder? i mean i need to know html/css or just python?

[novel stream]

probably yes. the project that serves the css from the CDN usually also serves it with a key by the end so that when a new one is created the browser will invalidate the cache and retrieve the new CSS file instead of the old one

[novel stream]

Yes, Django is a full web framework to build websites and full websystems. You will need to know some HTML/CSS for sure if you plan to work with Django. Now if you plan to work with APIs you kinda can skip HTML/CSS but some basic knowledge about it is totally worth it

Django Question:

I want to pass a search via a search bar of: dog, blue, tall

That will look up all tall, blue dogs in my database.

qs = qs.filter(dog__icontains=dog_contains_query)

only allows me to look up one parameter at a time, and will return all results with dog, bu tif I have dog, blue, will look for a match of dog,blue, and will return nothing.

So far ive given heavy consideration to AND as well as OR, and have even considered UNION, but I dont know if union would work, or even how to get it to work, and Im not sure what security flaws it may introduce, but Im pretty sure its not as bad as: raw() Execute a raw SQL statement

http://localhost:3000/?title_contains=with&author&id_exact=&title_or_author=&view_count_min=&view_count_max=&date_min=&date_max=&category=Choose...

i also tried this, which it shows very promising results, but I had to add this to the URL directly, vs using the search bar

Is it smart to use any python backend framework with an javascript frontend framework for example react with flask?

anyone know what the default timeout length for a flask request is?

Flask by itself doesn't have a timeout length. I think that's handled by the web server layer, one/two layers up

Hey can someone please help me in #help-bagel, it has to do with Flask and a Chat Apps formatting issues.

[native tide]

@pallid hill For some reason I can't type in the help channel. I didnt read your code because I'm on mobile at the moment but based on what your asking for i think overflow-x or overflow-y would solve your problem. Heres a good reference: https://www.w3schools.com/CSSref/css3_pr_overflow-x.asp

[ionic raft]

I've seen a number of web devs speak highly of Django and React. I haven't gone there yet, but the reasons-for presented have made sense.

And so, as for how smart this practice is likely a case-by-case situation. I haven't used React because the problems I've focused on have been functional-centric. However, I hear very good things in terms of managing front-end behaviour. React also appears to have a decent collection of libraries and an active community.

What I wonder about is that Flask is a fairly straightforward web dev framework. You can build out a lot of functionality, but one doesn't have to wander too far along the spectrum before Django presents good reasons to be used over Flask. I would be curious to learn about use-cases for Flask+React.

[ionic raft]

That's a HUGE question 😄 But I understand. I'll offer reflections from 10 minutes quickly scanning the github:

• **bike **is an interesting project name for a web app selling cars 🙂
• settings.py > brush up on environment variables, and secure all KEYS. SECRET_KEY should be changed, and hidden within an env var.
  -** use of sqlite3 **> If you're serious about Django, read up on other DBs, such as PostgreSQL.
• **MEDIA **on a django server is fine for small projects. If you plan to go production with a web app storing uploaded media files I'd brush up on other ways to do that. When you include Media on your Django app it is no longer stateless (Load balancing issues if project takes off) and there are security risks that come with file uploads
• naming of home app > I've not taken that approach. I name my apps based on their functional focus. The functional focus of home is...the home page? Looking at home.views.py very quickly reveals that this is the main car app. Perhaps car_sales_engine or something like that might be more descriptive. This is a minor detail, but when you're expanding your coding chops with projects containing more than 3 to 4 apps how you name apps is going to make a difference long term...

I'll stop there. That was the first 10 minutes. I hope that helps. Good luck. Love the energy and the movement towards full-stack dev.

Book I recommend: https://www.feldroy.com/books/two-scoops-of-django-3-x

[pallid hill]

I tried to add that in css but for some reason it does nothing, maybe some deeper implementation is needed, although I’m really not all to sure.

[proper hinge]

HTML Jinja templates are great for what they are, so it depends on your requirements. If you want to build an SPA or in general a very dynamic front-end, then I would a say a framework like React is the smart thing to do.

[native tide]

Thanks man for honest feedback!

Is there any way to get better logging from FastAPI? I have an endpoint that receives a fairly complex JSON object (a push webhook from GitHub) and sometimes my server just logs 422 Unprocessable Entity and nothing else. This would indicate that the data could not be deserialized into an instance of my Python class, but the error isn't exactly helpful in tracking down what it is.

Oh darn. I've googled this several times in the past, but now I stumbled upon the docs for how to handle errors. Never seen them before, so no wonder it's been a bit hard.

Basically I seem to want:

@app.exception_handler(RequestValidationError)
async def validation_exception_handler(request: Request, exc: RequestValidationError):
    exc_str = f'{exc}'.replace('\n', ' ').replace('   ', ' ')
    logging.error(f"{request}: {exc_str}")
    content = {'status_code': 10422, 'message': exc_str, 'data': None}
    return JSONResponse(content=content, status_code=status.HTTP_422_UNPROCESSABLE_ENTITY)

Let's deploy that and see.

TLDR; If you have time it won't hurt. Learning WP on your journey into web development can give you access to a *swiss army knife * web dev toolkit.

On my journey of becoming a web dev I started with WP. It has solid use cases, and some great solutions can emerge. It has a really broad community and plug in options to extend functionality. Is it beneficial to learn WP? That really depends on the use cases you're developing for.

However, WP comes down to how big the compromise needs to be to deliver on use cases and requirements. The three most pressing limitations for me were: 1. it is based on a framework that can make changes that can break your solution (WP Core - beyond your control). 2: It comes with performance overhead because it trying to be many things to many people. 3: Any changes to plugin functionality can also break the application (beyond your control). These limitations come down to a trade off of pros and cons. And perhaps the greatest one is that because WP is so popular as a CMS (Content Mgmt System) it comes with known vulnerabilities, attack vectors, that are rampantly exploited.

I found myself drawn to Python-Django because I wanted a much greater level of control for developing web applications on all three layers (DB, Application and Front-end). Understanding both WP and Django helps me qualify which use cases are better suited to which stack.

Good luck.

[ionic raft]

Interesting. I'd start by getting really clear on what I want to accomplish:

• It sounds like you will need user account functionality. Users will make their predictions and be scored based on the variance between their prediction and what happens. You want data related to users to persist and always be available. Needs will evolve as you delve into the user's experience and what you're trying to accomplish (such as leaderboards for world cups every 4 years)
• You will need login, logout and password reset functionality.
• You need to design a data model along with what the web application will do (application logic)
• You will also need to determine how you want to front end (the web pages themselves) to present and support this experience.
• That then informs how to design the data model, application logic and web page layout

On one hand, Flask is simpler to get started (for your first project). But based on the real need for account login, Django may end up saving you time overall (it's more complex to learn, but it has built in tools for things like administration and user-authentication).

Advice on where to learn how to do this really depends on how technically comfortable you are with Python and coding in general. I recommend Corey Schafer's YouTube tutorials for both Flask and Django. I spent about 1.5 months learning Flask before I shifted to Django because the projects I build are complex. However, that time with Flask introduced me to web development fundamentals that served me well when stepping up to Django (where I got the bells and whistles). I only code Django web apps now.

[jade dawn]

this is very helpful.
thank you so much

ill get started with tutorials then

[ionic raft]

Welcome to the journey into web application development. I started with an idea to build a web app to store information and automation steps for the process improvement methodology I train businesses on. Having a clear idea to drive your development is VERY helpful. Do you have much experience with Python?

[jade dawn]

mainly my experience comes initially being a mechanical engineer and working with matlab mostly. once i started learning about ai and machine learning i got interested in data science so i got started with python. this world cup prediction website i wanna try to build is just a fun project i thought of but hopefully can develop into experience in django or flask

[ionic raft]

that will be helpful. You likely have a number of programming concepts down in Python. However, you might be well served by taking a deeper dive into something like a python web dev boot camp. You will use libraries with Django (as you have with matlab for example). And you will lean heavily into many Python programming concepts. Your grasp of programming logic patterns will be helpful too.

And yes, I'm on my third deployed project now (my profile has a couple of links). Building a fun project on an idea you really get is a fantastic way to get experience.

At a guess you're going to find Django very compelling to meet your requirements thoroughly. User authentication in Django is top-notch. In Flask you have to do a lot more heavy lifting.

Disclaimer: I am a HUGE fanboi of Django. I think it's an astonishingly good framework to build a web app on.

[jade dawn]

hopefully i can easily understand some of the new concepts that django might bring haha

how would it compare to js?

[ionic raft]

Django is built on Python.
You'll use Python to build the data model (tables and relationships in the DB), and the application logic (the views that get things done). You'll use html to structure web pages, css to style web pages and Django's implementation of Jinja to build those web pages by the web server. And you'll find js will help you with managing web page behaviour. I use js sparingly (because browser based computation is slower than back-end server computation). You will have the option to delve into using a js framework (such as React) to make the most of sophisticated behaviour functionality built to solve front-end requirements.

[jade dawn]

this is very informative and good to keep in mind going forward
thank you for sharing

[ionic raft]

Good luck bruh. I LOVE developing web apps in Django. I've had a LOT of fun over the past year or so

[dapper vigil]

authentification_classes is not an iterator. (TokenAuthentication) is not a tuple, the parenthesis are just removed. If you want to make a 1-element tuple you need to add a coma after the value, like so: (TokenAuthentication,)

Hi everyone,

We are planning on developing an app which will have a facial recognition aspect and some machine learning aspects. This is a senior design project for our class so none of us are exactly experts. But we are trying!

I have done many ML projects but never an app using python. Our professor suggested using Flutter as its cross platform. But from what I am reading it may not be the best option for python APIs.

Could you let me know what your thoughts are for mobile development what should we use if we are decided on python APIs already?

You probably need to switch your IDE from working with global env to your local venv

[inland oak]

Windows paths aren't meant to work in html, use Linux like paths... And give a reading to Head First CSS book, it will teach you the way

[inland oak]

It will not matter for your Backend what u will choose for frontend.
Backend will just give away data in Json format / or web sockets in same way as any other backend

Choosing Frontend (mobile one) is usually best in the most compatible option with provided ecosystem. If u use Kotlin for Android, and Swift for iOS, u should be fine.
About framework details I don't know

Is it possible to reuse html filenames when using multiple blueprints?
Eg. I have Homepage blueprint and admin page blueprint, with their appropriate /templates directories. Is it possible to have index.html in both directories?
Right now, for some reason the admin blueprint always loads in the index from homepage

app/
├─ ui/
│ ├─ admin/
│ │ ├─ templates/
│ │ │ ├─ index.html
│ │ ├─ admin.py
│ ├─ home/
│ │ ├─ templates/
│ │ │ ├─ index.html
│ │ ├─ home.py

[worn aurora]

are u sure your view for the admin is correct ?

because both app are different

[zenith hound]

Should be. Lemme link u it

In the main file i got

app = Flask(__name__)
app.register_blueprint(main_bp)
app.register_blueprint(login_bp)
app.register_blueprint(admin_bp, url_prefix='/admin')

The home BP is:

main_bp = Blueprint('main_bp', __name__, static_folder=Paths.main_static, template_folder='templates')
@main_bp.route('/home')
@main_bp.route('/')
def home_page():
    try:
        return render_template('index.html')
    except TemplateNotFound:
        abort(404)

The admin BP is:

admin_bp = Blueprint('admin_bp', __name__, static_folder=Paths.main_static, template_folder='templates')
@admin_bp.route('/home')
@admin_bp.route('/')
def admin_page():
    try:
        return render_template('index.html')
    except TemplateNotFound:
        abort(404)

When i go to http://127.0.0.1:5000/ i get the usual homepage, and when i go to http://127.0.0.1:5000/admin/ i still get the same home page

[worn aurora]

where is /admin route ?

[zenith hound]

Wdym by that?

[worn aurora]

is
@admin_bp.route('/admin') not required ?

[zenith hound]

Its from the url prefix right?

When you register the blueprint

[zenith hound]

If i change the admin index to index2 or whatever else, it works fine.

Thank you 🙏

[olive hazel]

guys literally tell me what are the things and skills needed for making and publishing a portfolio website
i know the html and css part

do i need aws or heruko?

do i beed mango dbl

or sql

[inland oak]

Firstly decide if you wish being frontend, backend dev or devops engineer, then we can answer that

[olive hazel]

whole stuff mate

it certainly doesn't need Javascript i know that for sure

[inland oak]

https://roadmap.sh/ check the roads there, and decide for yourself

the backend road is awfully missing a lot of things though

[olive hazel]

no i need .com domian

[olive hazel]

portfolio doesn't take backend work

[inland oak]

https://github.com/darklab8/darklab_backend_roadmap
i tried to draw how backend road looks like better... all the additional green SWE stuff

[inland oak]

so, if you build portfolio web site, you are supposedly going into direction of being frontend (or even worse, full stack xD)
besides html and css, you are supposed to know javascript first then, and frontend framework like react or vue.js or angular

[inland oak]

you will need something to host it definitely. Anything that you wish fill it. Even github pages can host a staticly built website. So kind of you can go without aws/heroku

[inland oak]

mongo db is for backend path. if you wish to build a cool server side stuff, and having frontend is just secondary/non important thing for you, then mongo can be important, otherwise not. Although as average tool, we all use SQL database first. fifty shades of NoSQL databases come later after that, once you understood what for SQL and when could be needed no SQL

[olive hazel]

yeah realated database and un related database

so what i need is angular and Javascript

i didn't get the part where u said github

can it host a website?

what will the domain in that case

[frank shoal]

github can host static sites. The domain will be yourname.github.io

[inland oak]

If the website is without backend. Only having html/CSS/js. Then it can be hosted on GitHub. It will auto generate domain for u

[frank shoal]

You can also configure a CNAME to use your own domain

[olive hazel]

can i change the domain and do i need to pay for service

[frank shoal]

note: changing the domain means you won't get free ssl/tls

[olive hazel]

like .com?

[frank shoal]

yes, but you have to own it

[olive hazel]

10 cents lol

[olive hazel]

own the website that i make

[inland oak]

SSL will be free anyway, if he would use Cloudflare.... Or letsencrypt

[frank shoal]

own the domain from a broker.

[inland oak]

No point in paid certs

[frank shoal]

free as in effort

[inland oak]

Cloudflare is no effort

[rigid laurel]

You don't need Cloudflare for TLS on Github pages

and there's not really any reason to use it

at that point - just use Cloudflare pages

[olive hazel]

man when a average person visits a website first thing they notice is the domain

[rigid laurel]

This is wrong. https://docs.github.com/en/pages/getting-started-with-github-pages/securing-your-github-pages-site-with-https

[olive hazel]

so google domain is a good broker ?

[frank shoal]

Yeah. I use amazon

[olive hazel]

aws

is there any extra skil required for Github

why go daddy isn't good?

git is a lang?

[inland oak]

Cloudflare for the win

[inland oak]

Domain and cert are different things

[olive hazel]

doesn't matter who provides the domain right we just need that .com

[inland oak]

Domain matters
Certs are auto provided for free

[olive hazel]

namecheap isn't?

how much does that cost

what your website melio lemme check it

yup empty

did u do any backend work on that

wow

u didn't do any html or css or any front end at all right

i bet u can't do like 3d stuff and like that

with it

so theres no point in freelancing

anyone can do that right

what do u call this aws and heruko and github server side?

hugo?

aah

alr lets just hope right

what makes me compete with a website generator is that i can think. shortly that will be done as well

i mean client can't think creativity and thats why im there

anyways thank you all very much

Hey! could someone help me out here? Please direct me to the right channel if I'm not in the right place.

I've built an application in flask, and it works perfectly fine in the production flask server.
I'm trying to deploy it using gunicorn. I've setup a gunicorn_config.py file, and I'm running with the command bash sudo gunicorn -w 4 'app.main:create_app(testing = False)
But here it suddenly tells that worker failed to boot, and it appears the reason is ```line 3, in <module>
from flask import Flask, request, render_template, send_file
ModuleNotFoundError: No module named 'flask'

I've run pip list and Flask is available in the environment, pip install flask is showing requirement already satisfied, and I've rechecked to make sure it works on it's own without gunicorn.

Could someone help me figure out how to debug the issue here?

like i have a video upload endpoint, it does

• receives multiple video files and iterates through them
• inside the iteration it checks to see if Redis has cached it
• checks to see if the video exists in the db
• saves the file
• compresses the video (takes 5-10 seconds)
• writes to db
• then it dispatches the video to another processing endpoint
  and repeat until there are no more videos received from THAT request.

is that too convoluted? or is that okay

What db are you guys using for your stack ?
Django / React.

I usually use jawsdb over postgres for regular django . There’s 101 videos arguing benefits for all of them though

[opaque rivet]

so, JWTs are often used because they are stateless and don't need storing on the db. But, refresh tokens have to be stored on the db no? so JWTs are not really stateless?

[inland oak]

It depends on your implemention

If u use JWT with validating it by secret key and not using dB request. Then it is without dB

JWT can contain additional token that is stored in dB, that can be deleted

Then it will require dB

We have a free reign for everything

Although in second case usually JWT is not used I think. We can transmit directly token in cookie without JWT that we will verify in dB

I think it is called Session token/Auth or something

The point of JWT is technically zero, if we already use session token

So let's consider JWT as thing only without db

Or wait

We can combine both

Let's have JWT storing session token

If JWT is not expired, then allowing request

If time expired or more sensitive request, then verifying session token

[opaque rivet]

sure, but if I'm wrong, people look to use JWTs over sessions so they don't have to store the tokens in the db. There would be no reason to use JWTs + session cookies for that reason

but learning about JWTs and refresh tokens I thought that the refresh tokens had to be stored in the database

but I suppose they do not have to be

can make the refresh tokens JWTs made from my secret key, and some user info (e.g. user_uuid) to make the refresh token specific to that user

so no tokens have to be stored in the db, that's great 👍

[opaque rivet]

so a refresh token is just a JWT with a longer expiry date?

I want to be able to use the inputed phone number text as a variable in my python code when it is submitted. How do I do that?

[frank shoal]

you need to make a POST route

i.e. @app.route("/", methods=["POST"]) then use the request.form variable to get the post data

actually, you're already using get, so you can just do request.form

Also, use the tel type for the input.

but that's a pervert way. Better linking in a normal way

[agile gyro]

sheesh

ok i dont even know how to link

[inland oak]

Imagine nginx web server

[agile gyro]

im not good with websites jsut fyi

[inland oak]

It just gives away your statically compiled vue.js web site to user

It is at his client side in browser

There(from user browser) u can make http requests with Axios, in GET/POST and etc way to your hosted Django application

Django application in a simple Rest API way accepts JSON inputs and answers results in JSON too

[agile gyro]

ok i get it

makes sense

have u hearda webflow

[obtuse robin]

does react work well with django?

[carmine cipher]

Hello guys, assume I am a web developer for 2 years , how long can take me to learn WordPress?

[inland oak]

No difference

Except learning curve of react more complicated than Vue.js

[native tide]

Thanks for answering. I have 2 more questions.

1. Once I make a new user class(using abstractuser), does it automatically override the existing user class to be considered as the user class for the project?
2. Is there a big difference between the extending the pre-defined user class or creating our own user class in terms of practicality? What's the benefit of one over the other on a website?

[worn aurora]

When u make a new user class (abstract user) u must specify it in settings (base)
Hmm,
As for the difference subclassing user is done when you are in the middle of the project and want to extend the current user,
Abstract is used when you are starting a new project and want to control everything about the user

Hi, im tryna deploy my app however im getting a ValueError: Required parameter not ste for the following:

<img src="{{ request.user.profile.picture.url }}" class="rounded-circle" alt="Profile Picture">

i dont understand why im getting this since i have all the environment variables set properly

[versed ivy]

It's not clear enough! Show the full error.
and maybe the url is returning different result to be ValueError.

[dusk sonnet]

the website currently works fine on my local machine however the deployed version doesnt work due to the above error

[versed ivy]

maybe try user.profile... instead of request.user.profile... 😐

[dusk sonnet]

the original was user.profile.... and i was getting the error

i changed it to request.user... to see if it worked but same thing

[versed ivy]

the user object gave no error! because the user.is_authenticated works fine.
so, the problem should lie inside the user.profile or user.profile.picture or the url of the profile class.
try checking the attributes of the user in your terminal.
before rendering, print the user.profile.picture.url and see if the error is coming from the user.profile attributes.

[dusk sonnet]

yes the error is coming from user.profile. I checked it before.

[versed ivy]

so you need to check the User model. and link the profile model with it, is that part ok?

[dusk sonnet]

ye that part works. When i check the admin dashboard everything works fine except my profile model. When i click on a user in the admin dashboard inside the profile model i get the ValueError: Required parameter not set error

im gonna delete all the environment variables and set them again once again lol

Flask. Paths, Saving files.

def write_sample_file(save_to_path):

On route:

But stackoverflow (https://stackoverflow.com/questions/36649703/get-root-path-of-flask-application/36651006#36651006 )insist people use instance path instead of root. WHY? HOW?

root_path: /home/[PCNAME]/Coding/flask_path

instance_path: /home/[PCNAME]/Coding/flask_path/instance

flask docs have:
UPLOAD_FOLDER = '/path/to/the/uploads'

which is not useful and seems like hard-coding path to config.

Anyone have any links on best practices to interface Discord with Django?

[worn aurora]

column name should not be enclosed in "

[worn aurora]

using webhooks ?

[viscid valley]

I'm not quite sure, I've done it before just using the Discord library living inside an app called discordbot, was a mess.

[worn aurora]

as django does not fully support async its not generally used to bridge, it would be much better/eaiser if u use FASTApi and such

[viscid valley]

@worn aurora Thanks, could you provide some material so I can start on the right path? Thanks for the help 🙂

[worn aurora]

its pretty easy tbh
here is a bot i made a few days back that uses the same thing
https://github.com/battlefield-portal-community/ranger/blob/main/bot/dashboard/dashboard.py

so u do this on global level

        app = FastAPI()
        discord_client = DiscordOAuthClient(client_id, client_secret, redirect_uri,
                                            scopes=("email", "identify", "guilds"))

        dashboard_root = project_base_path / "dashboard"
        static_path = dashboard_root / "static"
        app.mount(str(static_path), StaticFiles(directory=static_path), name="static")
        templates = Jinja2Templates(directory=dashboard_root / "templates")

        from bot.bot import Ranger

        if os.getenv('DEBUG_SERVER', '').lower() != 'true':
            bot = Ranger(debug_guilds=[
                int(os.getenv('GUILD_ID'))
            ])
            ensure_defaults()  # blocking call
            bot.load_custom_cogs()

then

        @app.on_event("startup")
        async def startup():
            logger.debug("Starting Bot....")
            if os.getenv('DEBUG_SERVER', '').lower() != 'true':
                asyncio.create_task(bot.start(os.getenv("DISCORD_TOKEN")))
            else:
                logger.debug("Server Debugging turned on... skipping starting bot")

this also has code for Oauth, so u can skip it if u like

template serving in fastapi is a bit slower than django but it makes up for it by making it easy to develop

btw what is your end goal ?

what does it means ?

like this is wrong, look at the where clause

Hey

Does someone know how to get form information with Flask?

I am trying this

    <form>
        <input type="text" placeholder="Nombre">
        <input type="text" placeholder="Apellido/s">
        <input type="text" placeholder="DNI/NIE/NIF">
        <input type="email" placeholder="Correo electrónico">
        <input type="password" placeholder="Contraseña">
        <input type="password" placeholder="Confirmar contraseña">
        <button>REGISTRARSE</button>
    </form>

@app.route("/cliente")
def clientes():
    return render_template("cliente.html")

@app.route("/cliente", methods=["POST"])
def clientes_post():
    print("ASD")

[obtuse robin]

you need a submit input in the form

and put the attribute method=“POST” on the form tag

you also need to put an id on the form tag to later distinguish it in python

[solar heath]

how do I get form answers by form id?

[obtuse robin]

on the function do

if request.method == "POST":
  form_information = request.form['form_id']

@app.route("/cliente")
def clientes():
  if request.method == "POST":
    form_information = request.form['form_id']
  return render_template("cliente.html")

@app.route("/cliente", methods=["POST"])
def clientes_post():
    print("ASD")

should be here

also youre using the same app routes

that wouldnt work

they all go through the same one

[solar heath]

like this?

[obtuse robin]

sure

but if you want information to be pulled from the post youd need to use request and access the form

[solar heath]

I get an error

[obtuse robin]

what is it

[worn aurora]

u need to add type hint

[solar heath]

Like this?

[worn aurora]

ohh flask, i though we were on fastapi

and

you should close the help channel if your asking for help here

[obtuse robin]

is the form on index.html?

[solar heath]

yeah

no

[obtuse robin]

you need to move everything and put your if request.method == post there

[solar heath]

it's in cliente.html

[obtuse robin]

oh

[solar heath]

(I am accessing through /cliente)

[solar heath]

👌

[worn aurora]

How much django would one need to know to be able to build a website similar to this? https://www.erepublik.com/ (basically a social network disguised as a "game")

I have the basics of django down(models, fields, databases) but I don't know stuff like property decorators, signals etc. Should I learn those before trying to build a website like this? or can I build it with just knowing the fundamentals

[obtuse robin]

ive done request.method and it works

[worn aurora]

u can remove the param from the function def

[solar heath]

kk

now it works

[obtuse robin]

arent what you did flipped? shouldnt it show the cliente html if you did not get a post request

hm

[native tide]

@worn aurora thoughts?

[obtuse robin]

okay glad it works

[solar heath]

yeah

now it works

now how to get form inputs

id from form is "register"

[worn aurora]

hmmm i can't login to the game, so not sure what all is there,
but bare-bones will be
django, db, user management, websockets

as i cant see the acctual game cant really say much

[native tide]

well there's different countries and you join a country, you can start a business, fight in battles where all citizens from one country fight vs all citizens from other country and u just have to press one button to "fight". the whole game is pretty much text-based.

the main thing would just be the same functionality as a social network website(like a really watered down facebook)

[worn aurora]

ahh then i guess above mentioned things will be enough

[solar heath]

How do I get the form inputs?

[worn aurora]

https://www.google.com/search?client=firefox-b-d&q=flask+form+input

Let's say I have a currency model for my application(shown below). the application will have multiple currencies.

How would I go about implementing it so that each user can have a certain quantity of some currencies? and with methods that can increase/decrease currency in someone's account

This is what I've written so far:

class Currency(models.Model):
    name = models.CharField(max_length=100)
    symbol = models.CharField(max_length=100)
    country = models.ForeignKey(Country, on_delete=models.CASCADE, default='')

Should I create a foreignkey field within the user profile? but how would I implement quantity of currency then?

Its also perhap scaled a bit too large for mobile

ye im not sure what to do about that, i thought it's because of heroku.

ah fair enough, ill lower the sizes more

it might be slow because of the pictures because i dont resize the pictures since i dont know how to create a lambda function for it

[spring oriole]

I think if you use a program called fiddler you c a actually generate Python code for a given request

It’s been a while since I used it but I think it’s possible to right click and ask for Python code. It’s basically a proxy that sits between the backend and your browser when you use websites. That could probably help you learn. Also curl

If you read about http verbs that should get you started. The most common are create, read, update, delete (CRUD) The get request is the read one. You can see this in the network tab by clicking Fetch/XHR this filters the list of requests to only show http requests.

So im making a little flask project where i enter a city name in a stringfield and then click on the submit button and then it shows me the weather of that particular city in a html card
the problem im facing is that i am unable to find a way to display the card once the form has been submitted.
i think i shud be using an if statement using jinja templating but i am having a hard time figuring out how to get it working

<body style="background-color:rgb(91, 94, 166);">

    <div style="text-align: center">
      <div class="col-auto">
        <form method="post" action='{{url_for("index")}}'>
          {{form.hidden_tag()}}
          <h1 class="display-6">Enter City Name</h1>

      <div style="width:70%;margin:auto;padding-bottom:10px;">
        {{form.city(class="form-control")}}
      </div>
      <div class="col-auto">
        {{form.submit(class="btn btn-outline-secondary")}}
        <!--<button type="submit" class="btn btn-outline-secondary">Search</button>-->
      </div>
      </form>
    </div>
  </div>
  {% if form.city.data is not none%}
  <div class="card" style="width: 18rem;">
    <img src="..." class="card-img-top" alt="...">
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
      <a href="#" class="btn btn-primary">Go somewhere</a>

heres the html

@app.route("/",methods=['GET','POST'])
def index():
    form = CityForm()
    if form.validate_on_submit():
        print(form.city.data)

How do I deply a Flask app (ubuntu server)

I have it deployed but it might be causing conflict with my other website

[rigid laurel]

You probably need to put it behind a reverse proxy such as Nginx or Caddy - or if you already have one, you might need to reconfigure it

[solar heath]

I am using nginx

@rigid laurel

[rigid laurel]

It looks like you're running it with the flask dev server - that's usually a bad idea - here's a DigitalOcean article walking you through the whole setup of using Nginx + Gunicorn which I'd suggest trying to apply to your specific app. https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-gunicorn-and-nginx-on-ubuntu-18-04

[solar heath]

ik

I am already looking a video tutorial

before continuing I want to know how to host two websites at the time

[rigid laurel]

once you've set up one app, adding another is fairly easy. I haven't used Nginx in years, I've used Caddy instead, but iirc you just add another location section to your Nginx config

umm

how do i do this ?

@echo cloak

[echo cloak]

download chromedriver source code, modify chromedriver and re-compile $cdc_ under different name. @autumn veldt

i get an error

look

OSError: [WinError 216] This version of %1 is not compatible with the version of Windows you're running. Check your computer's system information and then contact the software publisher

but it worked before the change

[echo cloak]

with what name did you changed the $cdc_ ?

[autumn veldt]

abc

$abc_

[echo cloak]

you have to make sure that the replacement string (e.g., dog_) has the same number of characters as the search string

[echo cloak]

ohh

its the same no. of char

[autumn veldt]

$abc_asdjflasutopfhvcZLmcfl_

Hey All, I am trying to re-direct a url from a function in views.py, but upon running the api
I get "function at 0xxx14" some mem Location .
I am using return redirect (url) . Can anyone suggest something here .(Django)

[inland oak]

https://docs.djangoproject.com/en/4.0/topics/http/shortcuts/#examples this looks like full of examples for django 4.0🤔

[versed ivy]

Ummm... can't explain properly in text! but you may take a look at this video which I followed for my django tutorial (https://youtu.be/5zNR3E6WRLE?list=PL4cUxeGkcC9ib4HsrXEYpQnTOTZE1x0uc&t=50).

Then it is highly recommended that you read through the docs for sometime and if you have any specific problem understanding some parts, ask here again.
Don't be discouraged to ask.

Django Models Docs: https://docs.djangoproject.com/en/4.0/topics/db/models/

[muted walrus]

@inland oak Thanks Buddy, I did refer this, wanted to know if we can also call a function in redirect? 🤔

[inland oak]

sure, why not? 🤔

I would recommend using reverse url function though

it is always better to reidrect by view name or by
transforming url name into its url https://docs.djangoproject.com/en/4.0/ref/urlresolvers/

[muted walrus]

Alright , haven't used reverse url, gonna check out the link which you sent. Thanks again

[remote pendant]

is there a way to change the name of object list inside the admin page of django instead of just object 1, object 2, etc?

[tight pike]

Kinda late but this is how Django documentation recommends to do things

It's simply a standard set by Django community and Django framework, made to avoid confusion and some type of future problems

try to add this in your models.py file in your class:

def __str__(self):
        return self.****

swap the 4 'stars' with a variable which contains the name of your object

example: if you got a class Post which contains many posts, you'll definitely have a 'title' variable, so you simply return self.title. Obviously after having modified your models.py file, then you gotta do python manage.py migrate & python manage.py makemigrations

[tight pike]

explanation above

[remote pendant]

Thanks!

[formal swift]

Anyone know what a 'OPTIONS' request is?

I am sending an API on iPhone and instead of a POST like my desktop does, it is sending OPTIONS

[rigid laurel]

typically used for a CORS preflight

it gets sent out ahead of CORS enabled requests by your browser

if you control the server - you probably want to handle it

not necessarily writing code to handle it - just respond to the preflight at the reverse proxy level, or with some middleware type thing like Flask-Cors

[formal swift]

Okay thank you

Just figured out why it is sending the CORS preflight. It is because I was on HTTP and sending the request to the HTTPS version of my website

damn that sucks haha I gotta learn js then

[remote pendant]

i mean django, what i want is when my user login, they can only view certtain pages.

[native tide]

oh I wouldn't have a clue then xd

[rigid laurel]

JS isn't too difficult to pick up. You can either just jump into it with trial and error, or work through a tutorial. The Mozilla tutorial is a little dry but fairly good if you go that way https://developer.mozilla.org/en-US/docs/Learn/JavaScript/First_steps

(I'm not actually 100% sure that's the right Mozilla tutorial, but Mozilla is definitely the place to go to)

[native tide]

so this will basically allow me to add logic based stuff to my website?

if u know what I mean

not just text and pics etc

[rigid laurel]

Yeah

[remote pendant]

for now, i just do an if statement in the html file that says you cant view this page.

[late stone]

hello friend, can i dm you?

[daring isle]

im not ready for that level of commitment lol, whats your question?

[late stone]

understandable, Ok so heres my question:

[late stone]

I am building an employer admin program.

Within my user management app, in my models.py file, I have a Profile class pointing to Company class using models.OneToOneField. The company class points to an Employee class via models.ForeignKey.

When I create a company profile and I create a company along with and it works just fine, but when i make more than one employee in relation to the company and works fine, but when I retrieve that employee, I get a just one employee. How can i make it to like whenever i call the employees by doing: obj.company.employee i get all the employees instead of the latest employees saved in the db

heres the models.py file with the models describe above: https://github.com/AngelM512/hr_program/blob/master/userMgt/models.py

i am very new to django so i am very thankful for your help

[daring isle]

class Company(models.Model):
    name    = models.CharField(blank=True, max_length=45)
    address = models.CharField(blank=True, max_length=255)
    employee = models.ForeignKey(Employee, 
                                on_delete=models.CASCADE,
                                blank=True,
                                null=True)

in your company obj you have an employee field, that will have one employee per company or a list of identically named companies with one employee each

is this intentional?

[late stone]

no, i want the company to have many employees but each employee can only work for a company

[daring isle]

class Employee(models.Model):
    first_name    = models.CharField(max_length=20,blank=False)
    last_name     = models.CharField(max_length=20,blank=False)
    prefered_name = models.CharField(max_length=20,blank=True)
    birth_date    = models.DateField()
    gender        = models.CharField(max_length=1)
    salary        = models.IntegerField()
    hired_date    = models.DateField()
    department    = models.CharField(max_length=45)
    company = models.Foreignkey(Company, on_delete=models.Cascade, blank=True,     null=True)

    def __str__(self) -> str:

        return (self.first_name +' '+ self.last_name)

add the company as a foreignkey to the employee model

remove the employee field from the company

obj = Employee.objects.filter(company='put company id here').all()

then you can query your employees like this

then obj will be an array of all employees with specific company

[late stone]

dude you are the best thank you so much. program is working the way i want it now

Hi,
What library do you recommend for rest api?
Exactly what framework is usually used for large commercial projects?
I would like to learn a framework that I can use in the future at work

[versed ivy]

I prefer Express.js for that. To me it's easily learnable, adaptable and it is widely used. [only my opinion]

[inland oak]

Fast API (considered best)
Django Rest Framework (considered best/or good... ergh it has its own strengths to provide uniform enviroment for any dev and blazingly fast development)

I am trying to work out task management with flask. So, say on a dashboard they submit a form and the form sends an rest API to another part of my server to do a task. If the page is refreshed will the task still happen?

Or if at the same time, another task is sent, does flask automatically handle it all?

[chrome belfry]

you mean like a todo?

or like a lambda?

[spare iris]

does anyone know?

[golden bone]

I doubt anyone will follow what you're trying to ask here without seeing some code

[spare iris]

i am so lost

[patent glade]

Does anyone know how I can see the actual implementation of the DOM?

The actual classes for Node, EventTarget, Document, and so on, in code form?

[proper hinge]

You'd have to pick a browser and look at its source code

[patent glade]

Guhhhhhhhh

Chromium is massive

[proper hinge]

Yes the major browsers are all big code bases

[patent glade]

I've tried to find the relevant parts a few times, but its all distributed

My task is to write a faithful implementation of the dom protocol (since technically its an interface designed to be implemented in any language) in python

[proper hinge]

You could try to search a browser engine's bug tracker for the classes you're interested in

Usually the issues link to diffs for fixes and whatnot

That should give you an idea of where things are located

[patent glade]

There's this document

https://dom.spec.whatwg.org/

Which I think is basically the recipe. But the tendrils of the DOM extend minutely, in every direction, throughout the mechanics of the browser itself that it's hard to know what I need to emulate

What I think I need is a base EventTarget class and a base Node class

[wise nest]

Hello!

I have a question. So I am trying to return a different html template with flask but when I click the button to do it, it doesn't work

[patent glade]

I need a bunch of node subclasses which act as mixins, and those are mixed together in various combinations to create elements, documents, document fragments, concrete text node classes of various types

[wise nest]

import os
import openai

openai.api_key = os.getenv("API KEY")

app = Flask(__name__) # Create an Instance

@app.route('/') # Route the Function
def main(): # Run the function
    return render_template('index.html') # Render the template

@app.route('/generate', methods=["POST", "GET"])
def generate():
  return render_template("generate.html")
    
if __name__ == '__main__':
    app.run(host='0.0.0.0', port=8080, debug=True) # Run the Application (in debug mode)```

     <input type="button" name="submit" value="Run Script">
    </form>```
I don't have anything in the generate html for the button

[patent glade]

In Javascript

What is a "namespace"?

[proper hinge]

Are you referring to when you do an import like import * as namespace from "module"?

[patent glade]

No, no, I'm talking about javascript

[proper hinge]

Yes, that is JavaScript code.

[patent glade]

1.4. Namespaces
To validate a qualifiedName, throw an "InvalidCharacterError" DOMException if qualifiedName does not match the QName production.

To validate and extract a namespace and qualifiedName, run these steps:

If namespace is the empty string, then set it to null.

Validate qualifiedName.

...```

[proper hinge]

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import

[patent glade]

Oh

Cool, okay

I guess I am...?

[proper hinge]

Is your question in the context of the JS language itself or in the context of the DOM standard?

Seems to be the latter

[patent glade]

Yeah, the DOM standard

[proper hinge]

I'm not sure then

Perhaps related to XML namespaces? I dunno

Yes, that actually seems to be the case after looking at the DOM standard

Here is where you can read about them https://www.w3.org/TR/REC-xml-names/

[ionic raft]

That's quite good for a single-page exploration of a number of well laid-out design elements. I like the overall design language. My personal preference is for more white space. Given the focus of the landing page, maybe greater padding for elements while continuing to use a screen-width container.

[ionic raft]

Are you coding in Django or Flask?

[modern wharf]

Thanks greate feedback! Have a nice day

[ionic raft]

I definitely appreciate the depth of research thru your comp sci degree, along with techniques you must be exposed to. For example, the loading rocket that then gets used for the top of page icon...

...that's sweet design language. Definitely talent there 🙂

Creative 🙂
