a new admin is created

ik

[native root]

This creates a lot of things, the database, some migrations, and a new admin user

right

later, you add code that tells django "whenever a user is edited or created make sure they have a profile"

[late gale]

yup that what i am trying to do

[native root]

Right, and you've done so successfully

there's one little hole

that first user has not been created or edited since, it already exists

and it never had a profile assigned

[late gale]

and how to fix that

[native root]

Simplest way is probably to just edit the user in the admin screen

[late gale]

so i make him the super user?

[native root]

He already is?

[late gale]

nope he is just active

[native root]

request.user is the current logged in user

what user are you logged in as?

[late gale]

I'm loggedin as the active user not the super one

[native root]

did you create that user before adding the post_save code?

[late gale]

nope

I create the user after i add it

[native root]

You can log into django admin right?

try something for me?

[late gale]

sure

what do u want me to try?

[native root]

Logging out and back in, I guess

[late gale]

that won't change anything

[native root]

Since User stores last login time, logging out and in should call User.save()

That should call your post_save handler

and fix things

[late gale]

why should i add User.save() when django saved the user once registered

[native root]

You shouldn't

Internally django will call user.save() for the logging in user whenever you do a login

ah, I missed a thing

@receiver(post_save, sender=User)
def create_profile(sender, instance, created, **kwargs):
    if created:
        Profile.objects.create(user=instance)

[late gale]

so anyways can't i make the profile be made for any user who just registered I don't want all of my users have the access to admin page plus I won't have the time to do a profile for more than 50 users

[native root]

Yes, lets do that

whenever a user logs in, django calls user.save() to record their last login time

that calls this code here that you've attached to the post_save signal

However, some users appear to have been created without a profile attached

[late gale]

true

[native root]

so created is True, but you still need to add a profile

You need to ensure that the user object has a profile attached

[late gale]

so do u mean is i need to check if the user have a profile if not create one for this user

but isn't this code do the same?

[native root]

No, it checks if the user is being created, and if so adds a profile

[late gale]

ooh

[native root]

Actually I'm going to give you an easier solution, sorry about not thinking about it earlier

[late gale]

np

[native root]

you're presumably running manage.py with python manage.py runserver [whatever] right?

[late gale]

ofc

[native root]

you can enter a django shell via python manage.py shell

Inside there you can manually clean up all the users that don't have profiles yet

You wont have to do so for any new users, thankfully

[late gale]

can't i just remove them from the admin page?

[native root]

You could, but the original admin user is one of them

and that could get awkward

[late gale]

i wont delete the admin user

just the others

[native root]

from appname.models import Model
from django.core.exceptions import ObjectDoesNotExist
for model in Model.objects.all():
  try:
    u = model.profile
  except ObjectDoesNotExist:
    model.profile = Profile.objects.create(user=model)

something like this, if you get it?

@uncut yarrow see #❓｜how-to-get-help

[late gale]

i can add this to the views

[native root]

You could, but it's written to apply to all models of course

[late gale]

so i can say

try:
profile = user.profile
except ObjectDoesNotExit:
profile = Profile.objects.create(user=user)

Do u mean like this?

oh wait

i got it

let me try

wait u are saying for model in Model.objects.all or do u mean from?

oh srry i got what u are trying to say

[native root]

👍

[late gale]

OMG!!

DUde i am literally crying happily

xDDDDDDDDDD

THANK YOUUUU

MWAAAAH!!

[severe mica]

hey all, was wondering if anybody could help me with an issue im having trying to autogenerate urls from url mappings (Link Building)

evrything shows up besides the links which I am trying to generate in the list titles scheduled meetings

[native root]

Well, first thing I notice is that the template is only given one meeting, but you're looping ove ra nonexistant variable Meetings

I'd also suggest djangos {% url %} template tag:

{% url 'view_name' arg %}

[severe mica]

what do you mean by the template is only given one meeting?

sorry I am very new to django

[native root]

return render(request, 'template_name_snip', {'meeting': meeting})

the {'meeting': meeting} is the variables passed to the templates

[severe mica]

yes but can wouldnt that create a dictionary as I add more meeting objects into the Meetings table i created in my models.py

which is why i thought it should loop through

[native root]

No, because meeting is a singular meeting you got via get object or 404

If you want to have access to all meetings in the template, you'll have to get them manually and hand them to the template just like you did the singular matching 'meeting'

actually

sorry

wait

You're using detail and list views

but you haven't posted the list view

[severe mica]

wdym by that?

[native root]

Your template is using the variable num_meetings but I don't see that being defined anywhere

it's not defined by default, so where's the code that comes from?

[severe mica]

oh yea thats beacuse thats in another views.py file

should i maybe move my detail function to that same file?

[native root]

No, the detail function isn't what's applying here so no reason to touch it

the list view is important

Django templates only have access to explicitly what you give it and a few default items

'Meetings' is not defined in the template, so its not listing any

you need to pass it within you list view

[severe mica]

ok will try to fix based off information you gave me thx

[cosmic cove]

Hey, what would you guys reccomend as a good authentication as a service provider for a website?

[cosmic cove]

ok, thanks

[valid crane]

im getting this error when trying to save an object to my model:

django.db.utils.IntegrityError: FOREIGN KEY constraint failed

am i using the ForeignKey method wrong? do i remove verbose_name or edit the value for the on_delete argument? for additional context, im learning this: https://www.youtube.com/watch?v=Rju5qdU0e58&list=PLnVyTqAVic7M4_pUJQ-KyxyL6ZLy4EM87&index=21

[dense slate]

Ok I am confusion. With google's OAuth2, I have the auth token/credentials and correct scopes for my needs, I just can't seem to find out where I get the actual user information from. Where is the response that provides the user email/username/etc.?

[frozen widget]

how can i change the post request data before the post request is submitted

for eg i want to add a token to the end of the post request but i want to do this on my backend

how can i do that

[verbal obsidian]

You can pass that token when rendering the template in context

and then put it in a <input type="hidden" name="myspecialkey" value={{ mykey }}>

@frozen widget

In that way, you won't be 'changing' the post request data per se, but adding that key to it

[limber laurel]

Can I using flask_login see if a view has a decorstor like login_required?

[verbal obsidian]

Why do you need that @limber laurel

[limber laurel]

I am making a navigation bar using url_map, so it is dynamic when I change a functions name, and right now my only problem is that some views require you to be pogfed in yet the header still displays it

[inland stirrup]

i am getting error when i am running this can someone help me

[fickle fox]

u didnt closed name in app route

[inland stirrup]

oh yeah got it

btw can i run two different files with flask functionality in one venv

cause after running the first file and changing the Flask_app to the second file and running flask it executes 1st file

[native tide]

I am trying to follow along with a django tutorial

i one of the videos he is going to \admin route and logging in with a user

then clicks on save and continue and works perfectly fine for him

but not for me

i use Django version 3.0 and sqlite3 version 3.29.0

Hi!

Does anyone speak Russian?

[hardy gazelle]

Hello everyone

is it Flask a good learning path for someone who never did a thing about web development?

[fierce sapphire]

what's best? django or flask?

[hardy gazelle]

@fierce sapphire as far as i know

there are good frameworks...flask more on the microservice side

and django on the full fledge side

this is the best blog i found about vs

[distant trout]

def delete_account(id):
    if current_user.is_authenticated:
        user = User.query.filter_by(id=1).first()
        db.session.delete(user)
        db.session.commit()
        return redirect(url_for('main.home'))```

    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(16), unique=True, nullable=False)
    email = db.Column(db.String(120), unique=True, nullable=False)
    image_file = db.Column(db.String(20), nullable=False, 
default='default.jpg')
    password = db.Column(db.String(60), nullable=False)
    posts = db.relationship('Post', backref='author', lazy=True)```

can someone tell me why this is not working? i get a NULL constraint error when I try to commit the delete of user.

https://i.imgur.com/QvTSecB.png

[verbal obsidian]

neither username or email can be null

have you check that none of those are null?

[distant trout]

yeah, i have email and username filled in

https://i.imgur.com/1U2p3Fg.png

the user id also works https://i.imgur.com/XwNfwm3.png

[hidden pier]

do you have any posts linked to this user?

it looks like deleting user breaks constraint on some post

maybe delete cascade is needed?

[distant trout]

hmm not sure what that is but i show u my post model

[hidden pier]

ok

[distant trout]

    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String(100), nullable=False)
    date_posted = db.Column(db.DateTime, nullable=False, default=datetime.utcnow)
    content = db.Column(db.Text, nullable=False)
    user_id = db.Column(db.Integer, db.ForeignKey('user.id'), nullable=False)

    def __repr__(self):
        return f"Post('{self.title}', {self.date_posted}')"```

https://i.imgur.com/5GOsO0X.png

this is a post i made

[hidden pier]

user_id = db.Column(db.Integer, db.ForeignKey('user.id'), nullable=False)

Here we go

so you have basically 2 options here:

• change user_id on Post model to nullable
• delete cascade -> deletign user deletes all related objects, like user posts

[distant trout]

oh

so right now the error shows because it is only deleting the user but it cant delete the post linked the user

is that right

so it shows an error

[hidden pier]

close, deleting the user makes Post relation to that user invalid, because relation is set to nullable=False

[distant trout]

OH

[hidden pier]

so it has to point to some user

[distant trout]

i see

[hidden pier]

you can make a guardian user "deleted" and always switch post owner to this

[distant trout]

wait is deleting cascade part of sqlalchemy

[hidden pier]

it is even part of SQL itself

[distant trout]

oh, that seems to be the best choice for me. I am going to research more into that right now

[real hare]

Using a Class based view in Django to display blog posts on my site. It is split across two directories on the site namely /posts and profile/posts. I want to filter the profile/posts to show the authenticated users posts only. How can I achieve this? Could someone share documentation that would demonstrate this?

[distant trout]

Thank you!!

[hidden pier]

https://docs.sqlalchemy.org/en/13/orm/cascades.html#delete

np! 🙂

[verbal obsidian]

Thank you!!
@distant trout in the view you can use, if request.user.is_authenticated

[distant trout]

@verbal obsidian inside the delete_account route?

[verbal obsidian]

what?

No

wait

Sorry mate, I pinged the wrong guy

[distant trout]

oh lol, its okay

@real hare in the view you can use, if request.user.is_authenticated

[real hare]

Thank you very much, I did not think it would be that simple

[verbal obsidian]

also, If you need that for the entire view

you can use the @login_requred decorator

[real hare]

Awesome, thank you 🙂

[native pasture]

Is it just me, or developing user interfaces in js/css is very time consuming?

[hidden pier]

nah, it just is 🙂 some frameworks make it a little easier sometimes if they let you put prepeared pieces together

you can use the @login_requred decorator
yep, django is awesome, you always have that request.user object and it's the logged in user or AnonymousUser by default and the have all this crazy methods is_authenticated / is_active etc.

[mint umbra]

does anyone know how I can make my submit button for my form take the user to another page?

<form method="POST" class="formone" >
    <input style="font-size:55px !important; font-family: 'Ubuntu', Helvetica, Arial, sans-serif; text-align: center; margin: 10px;" type='text' name='name' placeholder='Your name' /><br/>
    <input style="font-size:55px !important; font-family: 'Ubuntu', Helvetica, Arial, sans-serif; text-align: center; margin: 10px;" type='text' name='message' placeholder='Your message'/><br/>
    <input type='submit' id="feedbackbutton" value='submit' />
</form>

@app.route("/contact.html", methods=["GET", "POST"])
def contact():
    sender = request.form.get('name')
    message = request.form.get('message')
    client.messages.create(to="+1XXXXXXXXXX",
                           from_="+1XXXXXXXXXX",
                           body=f"From [{sender}]: {message}")
    return render_template('/contact.html')

using this right now. If I try to change the "action" in my html here, I my python ends up sending a blank message, and I get a method not allowed.

if I try return render_template("/formcomplete.html"), I get an internal server error.

I'm not completely sure what to do- help would be greatly appreciated!

Hi

Is there anyone here who uses Django?

[bleak bobcat]

This is the #web-development channel of a python discord, of course there are people who use django

[native tide]

@bleak bobcat anyone using python here?

[bleak bobcat]

Hmm. I'd have to check, not sure.

[opaque sail]

Can someone point me in the right direction for learning Django i tried the bloody tutorial 2 times from scratch and i Fail miserably...?

[lyric meadow]

Two scoops of django is pretty great and they just released their new version

[opaque sail]

Ok thank you :)

Django seems overwhelming rn

[lyric meadow]

I feel you

[opaque sail]

I wish ;)

[lyric meadow]

I tried learning django about two years ago but i'm not a dev

haha easy there partner

[opaque sail]

Shit

Ok

Im gonna give it a try

Ill let you kids know if I fail again

[lyric meadow]

Learning dash might be a good place to start if you have some python experience

depending on what your end goal is

[opaque sail]

I have some Flask and some PyQt expirience

[lyric meadow]

I would give Dash a look as you would know your needs better than me

[opaque sail]

I would like to build up an web service from ground up

[lyric meadow]

maybe django might be better

[native tide]

@opaque sail maybe try a video?
https://www.youtube.com/watch?v=F5mRW0jo-U4

I tend to learn best that way myself

[opaque sail]

Thank you guys I really wanna go trough this bush of code and find out what the heck is going on

Yea I like videos the most as well...

[coarse bay]

hi, im new to django and am making a website as part a challenge against my friends but im currently struggling with getting my css files to load. I'm trying to use the staticfiles to make it work but django isn't able to find it somehow?

i've set up my STATIC_ stuff in my settings.py like this ```python
STATIC_URL = '/static/'

#this tells django which files to find static=======#
STATICFILES_DIR=[os.path.join(BASE_DIR, 'assets'),] #
#===================================================#

STATIC_ROOT= os.path.join(BASE_DIR, 'static')

my file tree for my project looks like this

├───assets
│   └───css
├───blog

and in my assets folder i have```

but whenever i run in the cmd C:\Users\...> py manage.py findstatic css/styles.css it tells me that styles can't be found. Consequently when i run the collectstatic it can't add styles.css to my static files. I've tried just copying and pasting the file over but it still isn't able to find it? Do you guys have any tips or solutions to this issue? If so it would greatly apprecieted!

[dusty plaza]

Hey guys, good evening, I'm also new to django. Rn I'm working on a REST API using django-rest-framework. Whenever I want to write business logic I don't know if there is a proper or standard way to structure my files. I don't feel like business logic belong to models/views/serializers. Any thoughts on that matter? Can you share/explain if you have a file structure template and why you use it?

[molten quarry]

@coarse bay

STATICFILES_DIRS = [
os.path.join(BASE_DIR, 'static')
]```

From there you can just use the relative path in your templates

{% static 'admin/css/stylesheet.css' %}```

[coarse bay]

oh ok! i've changed it but im still getting this when i try to load my webpage

[molten quarry]

What's the line of the template look like?

[coarse bay]

what do you mean? like the views.py or the actual html file?

(sorry im really new to this)

[molten quarry]

Template refers to the .html

[coarse bay]

Oh ok!

oh sorry that cut a little short here

[molten quarry]

Okay, and you're DIRS right? In your code you have it as DIR

[coarse bay]

I did not. Im gonna try changing that

er i mean i did have DIR not DIRS

OK i changed and i am now getting this now.

[molten quarry]

Hmm. Might have mixed it up with STATIC_ROOT, though that's what you already had.

[coarse bay]

so should i change the 'static' in STATIC_DIRS to my original assets folder?

[molten quarry]

Try it

I always just have a single atatic folder with child folders.

static*

And then use the relative path in the template

[coarse bay]

what do you mean by child folders?

also it got rid of the static_files error when i changed it to asset instead of the static

[native tide]

Hi friends I'm new in Django can you put me on the right track

[molten quarry]

Subfolders.

[coarse bay]

Oh ok!

@molten quarry It works now! Thank you so much!

so after i changed the to the assets folder, this time the collectstatic actually got the styles.css from my assets folders and added it to static!

@native tide hello! what do you need? Im also kinda new to django but im willing to help!

[native tide]

@coarse bay I need to know how to start

[coarse bay]

Oh ok so the django website has a really nice tutorial that i used

@native tide https://docs.djangoproject.com/en/3.0/intro/tutorial01/

this one runs you through making a poll/voting app but it touches base on everything. As a consequence tho it is split into 7 parts then goes onto an advanced tutorial

which is a different project

is this the kinda stuff you were looking for? @native tide

[native tide]

@coarse bay Not exactly, but it's okay

@coarse bay Do you have the resources to learn?

[coarse bay]

like some youtube videos?

hmm.. do you have an idea for a specific thing in mind?

[native tide]

like some youtube videos?
@coarse bay
And books, Sites

[coarse bay]

ok! so i dont know about books but lemme go look through my bookmarks

heres one: djangocentral.com

https://djangocentral.com/

This one is pretty helpful. There's alot of guides to specific features or issues that you might implement or run into

Are you familiar with any frontend stuff like html,css, or javascript? @native tide

[native tide]

@coarse bay yes I've learned html & css but i'll never in Javascript

[coarse bay]

thats fine i haven't had to use javascript yet i just know its kinda important

[molten quarry]

I highly recommend the book "Django 3 by Example".

[coarse bay]

tbh besides django central i didn't use many other resources besides just googling issues on stack overflow or quora

or going through the django documentation on their website

i have to go rn but if i find any other resources ill be sure to send them your way @native tide

[native tide]

Oh yes thank you

=^_^=

[coarse bay]

np

[molten quarry]

9/10 resources will teach you what you want to learn, you just need to stick with it long enough. Don't let yourself get carried away by the vastness of the internet. Pick one and run with it!

[native tide]

Okay yes thank you Pro

Anyone use flask with vue.js? I'm trying to figure out how to turn my .vue files into static .html files to serve via backend routes.

[limpid comet]

I actually use Vue CLI to compile to HTML first.

And, mustache templating is possible, if you need SSR, or server to HTML communication. https://github.com/defunkt/pystache

[inland stirrup]

guys i am new to flask please help me out

i am using vs code and i've set up a venv in a folder of mine
i have 2 py files in it which are using flask
i used the app.py first(i did all that setting of FLASK_APP=app.py thing) and gave the command python -m run flask
it was successful but when i tried doing it for the 2nd py file which was using flask it ran app.py i've changed the FLASK_APP=app.py to FLASK_APP=application.py still its not running application.py

[vocal crag]

hello if im using flask and twilio is sending a post to a designated url how do i get that data twilio is sending me?

nevermind got it!

[tranquil steeple]

@verbal obsidian All I'm trying to accomplish it go get information from forms. So I'd like a way for flask to possible save them to some type of database.

[fickle fox]

yea thats possible

[verbal obsidian]

I mean

that's the way of doing it

you usually either have forms to save that information or to forward it to some other call

[native pasture]

Is there a way to pin the address bar in mobile browsers, ie. prevent it from hiding when scrolling? The solutions I've found online (setting overflow: hidden to html, body) don't seem to actually work.

[mint umbra]

hello, I'm currently trying to use this code

@app.route("/contact.html", methods=["GET", "POST"])
def contact():
    sender = request.form.get('name')
    message = request.form.get('message')
    client.messages.create(to="+1",
                           from_="+1",
                           body=f"From [{sender}]: {message}")
    return render_template('/contact.html')
    flask.redirect(url_for("formcomplete"))

but it simply doesn't redirect to formcomplete

[native pasture]

You're returning before redirecting. That statement never gets executed

I'm not quite sure what you're trying to do, but you probably want to check if the contact() function is being called due to a GET request (=> render page) or a POST request (=> form data received + redirect).

[mint umbra]

@native pasture POST I believe, I removed GET and it still works

[native pasture]

Well, normal http browser requests are GET. POST is usually used when sending data from a form. If your intent is to render a page when the user goes to /contact.html, that is gonna be handled with a GET request (with no form data). If you have a form in that page that submits to /contact.html itself, your contact() function is gonna be called in the context of a POST request.
One thing you could do is this within the function:

if request.method == 'POST':  # received form data
    # process form data and do stuff
    return flask.redirect(...)
else:  # render page
    return render_template(...)

Also, check the docs: https://flask.palletsprojects.com/en/1.1.x/api/#incoming-request-data

N.B. flask.redirect() generates a response object, and it's not gonna do anything if you don't return it from the route function (that is, send it to the client)

[mint umbra]

@native pasture sorry for the super late response. This solved my issue! thank you so much

[knotty eagle]

hello, i'm trying to create a simple web app that fetches lyrics from azlyrics.com
this code here:

@app.route('/lyric-request', methods=['POST'])
def lyric_request():
    song = request.form['song']
    artist = request.form['artist']
    lyrics = Lyrics(artist, song)
    return render_template('lyrics.html', title='Lyrics', song=song, artist=artist, lyrictext=lyrics)```
and here:
```html
<header>
    <link rel= "stylesheet" type= "text/css" href= "{{ url_for('static',filename='lyrics.css') }}">
    <h2>Song: <span>{{song}}</span></h2>
    <h2>Artist: <span>{{artist}}</span></h2>
    <p>
        Lyrics: 
        <br>
        {{lyrictext}}
    </p>
</header>```
is the code in question. However, for some odd reason, the lyrictext is not displaying on the webpage, even though Lyrics() returns a string. I've tested displaing multiline strings by setting
```python
lyrics = """multiline
    comment""" ```
and it still displays, so I'm not sure what the problem is.

I've made sure Lyrics() actually does find the correct lyrics, which it does, and if I call on Lyrics() from outside the function it will print out the correct lyrics too.

@limpid comet thanks! Is templating necessary when you can make API calls instead? I assume JS is compiled with the HTML.

also, my project isn't too big, so it won't be a problem.

@next tree If you don't need Jinja2 templating, just throw everything into static folder, and it should be fine.

[midnight needle]

how can i deploy my flask server to an different address than localhost(127.0.0.1) ?

[lilac belfry]

Don’t quote me on this but if I remember correctly you would do this:

app.run(host= '0.0.0.0')

So just edit the run argument

To run the flask server on your machines IP

(Locally)

[crisp saddle]

@midnight needle use something like Gunicorn, or Uvicorn.

gunicorn --bind 0.0.0.0:5000 app:APP

if your Flask aplication is called APP inside app.py

then you would use an edge router like Nginx, Apache or Traefik to actually map port 5000 to a domain if you have one of those :-)

[acoustic oyster]

hello friends: I have a discord.py bot that I would like to interface with my Django app. I would like to start by using my django app to save data from the bot to mysql database so that I can manage it from the admin site on django.

After hours of googling it appears no one else online has done something similar. Any thoughts on how to accomplish this?

[zealous siren]

Build a rest API that bot can post to

[acoustic oyster]

that is what I was thinking, but it felt silly

[zealous siren]

why? That's perfectly normal method

That's how @lavish prism works

[acoustic oyster]

It seems like a bit much since both the django server and the script are running on the same machine... But I am fairly new to this side of python lel

[zealous siren]

other option is have bot pull data from MySQL database

depending on what you are doing, that might work

it's not considered best practice

[acoustic oyster]

I was just gonna write the queries myself, but I figured it might make more sense to do it through django in the first place.

I am very new to django.

[zealous siren]

best practice is REST API from Django because proper microservice is Django should be only one to mess with it's database

[acoustic oyster]

would it be reasonable to do all the DB stuff through the discord bot, but still be able to manage it though django?

[zealous siren]

doing MySQL queries is probably easier

[acoustic oyster]

ok, I am very interested in best practice though

[zealous siren]

Best Practice, REST API the bot reads/writes to

what are you hopingt o change on the bot from Django?

[acoustic oyster]

It is basically just data for an RPG game I made for the bot that is currently just locally stored in JSON

[zealous siren]

What will Django provide?

stat site?

[acoustic oyster]

I would need to change values, delete data, sometimes create.

I was mostly just hoping to use the neat front end interface of the admin page with all the models.

Eventually I will display everyone's character data on the site I have.

[zealous siren]

ok

[acoustic oyster]

And allow users to create/delete/modify their characters through the site

[zealous siren]

BTW, PostGres is considered better Database Engine at this point to go with

then I would have REST API the bot can read/write from

[acoustic oyster]

I was aware of that when I decided to use MySQL thank you LOL

[zealous siren]

make sure you use aiohttp on discord.py side to prevent blocking

[acoustic oyster]

But setting up postgress failed for me like 5 times on ubuntu so I gave up lol

[zealous siren]

but yea, REST API, gold standard in moving data between applications

[acoustic oyster]

alright, awesome. Thank you so much for your help.

My other friend also recommended this, but I was hesitant.

I am also too scared to move over to posgres since I have nuked a database or two in the past by accident

[zealous siren]

it was suggestion, MySQL/MariaDB isn't terrible and depending on your size, it may not matter

[acoustic oyster]

I do not need crazy performance just yet, but I really do need to switch over. My site is getting more traffic than expected haha

[zealous siren]

performance is really more proper SQL queries

and building right tables

[acoustic oyster]

well luckily Django means I can remain ignorant of that

Anyone have experience with django ? I'm having trouble trying to figure out this model setup for a cart + pizza model. Cart should be able to contain multiple pizzas. I tried to do many 2 many but it was only allowing for 1 pizza of each kind

[quasi ridge]

many to many sounds wrong; can one pizza live in two carts?

[native tide]

I thought so but was recommended to swap to foreign key (1 to many). My reasoning was multiple carts can order the same item.

With FK though theres no add method, so how can I add a pizza to a cart?

[celest torrent]

Quick question regarding Django, is there a preferred way to write views? Classes or functions? Finding classes hard to do what I want them to do but it's probably because I don't understand how Django uses them fully

i.e.

def home(request):
    context = {
        "posts": Post.objects.all()
    }
    return render(request, "blog/home.html", context)```

VS

```python
class PostListView(ListView):
    model = Post
    template_name = "blog/home.html"
    context_object_name = "posts"
    ordering = ["-date_posted"]
    paginate_by = 10```

[marsh canyon]

I always prefer class based views as they are more organised and you also get many built in ones

but i guess it comes down to ur preference

you can implement the home view using class based views in the following way:

from django.views import View

class Home(View):
    def get(self, request):
    context = {
        "posts": Post.objects.all()
    }
    return render(request, "blog/home.html", context)

you can also use template view and then modify the context

@celest torrent

[noble wren]

how can I get the value of this form in my views.py class

type_of_place = request.POST.get('typeform') Trying that gives me a value of none

[snow dragon]

What value are you trying to get? You just have submission buttons but no form inputs. Try looking through: https://docs.djangoproject.com/en/3.0/topics/forms/#building-a-form

Keep in mind that you don't have to use Django's built-in Form class, you can always write the HTML yourself too as you've done above.

[noble wren]

@snow dragon im trying to get the value that the button is

like value='parks' or w/e it is

I dont want any user input, they can only choose through the buttons

[snow dragon]

Usually that would be something like a dropdown or checkboxes. Notice the type=submit means those are buttons to submit the form, not usually the value itself. Although I guess you may be able to get that value out somehow. Never tried it.

@noble wren

[noble wren]

I see

[main dirge]

This is probably a rather naïve question, but how homogeneous are element names/divs for different websites that serve the same function (generally speaking)? IE, would it be foolhardy to crawl 50 different websites' HTML, figure out what the elements were which directly corresponded with a login portal, and expect to have any predictive understanding for the next 50 websites' HTML?

[snow dragon]

@main dirge Unlikely. Most of the web is held together by duct tape and 50 is a small sample. Source: I work for a major corporation that owns dozens of websites and I have live ML products on a handful of them.

[main dirge]

At what point do you think the sample size would be large to see any payoff, 10,000?

enough to*

[snow dragon]

Depends on what you mean by "predictive understanding"

[lavish prism]

Rules

5. Do not provide or request help on projects that may break laws, breach terms of services, be considered malicious/inappropriate or be for graded coursework/exams.

[main dirge]

@snow dragon ? https://towardsdatascience.com/web-scraping-is-now-legal-6bf0e5730a78

Can companies use TOS to stop people from scraping data that isn't private or proprietary (data would be public), especially if there is no gate-keeping of the information itself? Seems doubtful if there is no ill intent.

[snow dragon]

@main dirge If you're looking for login pages, that argument is defunct since that data is not publicly available, it's behind a login.

[main dirge]

But just the login itself wouldn't be off limits, right? I'm not looking to login to scrape data.

just to figure out if a page has a login, that's all.

To be clear - the pre-login, login page.

[snow dragon]

In your now-deleted messages it was pretty clear that was not the intent and so I'm going to maintain my position that I'm uncomfortable in helping any further.

[main dirge]

No worries.

I should've expressed my intent better, but it wasn't to scrape data behind paywalls.

or logins, for that matter.

Just to determine whether the page had a login for volunteers who would be following up.

Regardless, I appreciate your response.

[snow dragon]

If we're only looking for login pages, it should be relatively trivial, no ML involved. Just look for <input type="password" tags in the HTML

That obviously won't be perfect since many sites can use that tag for other private input fields that are not necessarily passwords, it would give you a good starting point of pages to follow up on.

[main dirge]

Thanks. I didn't mean to put you in an uncomfortable position. I'll try that.

Sorry that I did.

i tried backdrop-filter: blur and it's working fine with google chrome but not with firefox

[native root]

backdrop-filter is only supported in nightly firefox at the moment

the going trick for this effect is to have the same bacground image on blur and to have a "below" background layer with blur applied to it

[autumn plank]

@native root that would be 2 blurred layers if I did that!

No, just one, since you don't blur the upper layer anymore

@spark frigate you want to add the code and the state as parameters to your endpoint?

[spark frigate]

yes

@candid whale

[candid whale]

so the code is a string and the the state is an int?

[spark frigate]

yes

[candid whale]

im not very familiar with 2 parameters in an endpoint but try something like this:
@app.route("/login/string:codeint:state", methods=['GET'])

and you also need to define them so def login(code, state)

Asking good questions will yield a much higher chance of a quick response:

• Don't ask to ask your question, just go ahead and tell us your problem.
• Don't ask if anyone is knowledgeable in some area, filtering serves no purpose.
• Try to solve the problem on your own first, we're not going to write code for you.
• Show us the code you've tried and any errors or unexpected results it's giving.
• Be patient while we're helping you.

[rigid laurel]

Hm - I haven't ever actually used this part of Django myself. All I can do is try and suggest debugging strategies

but first

you don't have that in yours

yours is slightly different

oh wait - different thing

[native tide]

I'm am also a complete beginner at Django😁

[rigid laurel]

Do any filters work for you?

[native tide]

i get an error

when i go to that url where the search btn actually is

[simple sentinel]

What does your Order model look like?

[native tide]

class Order(models.Model):
    STATUS = (
        ('Pending', 'Pending'),
        ('Out for delivery', 'Out for delivery'),
        ('Delivered', 'Delivered'),
    )
    customer = models.ForeignKey(Customer, null=True, on_delete=models.SET_NULL)
    product = models.ForeignKey(Product, null=True, on_delete=models.SET_NULL)
    date_created = models.DateTimeField(auto_now_add=True, null=True)
    status = models.CharField(max_length=200, null=True, choices=STATUS)

    def __str__(self):
        return f'the {self.status} {self.product} that {self.customer} ordered'```

[rigid laurel]

looks like you're missing that?

you don't pass in the queryset into your filter

    content = {
        'customer': current_customer,
        'orders': orders,
        'total_orders': orders.count(),
        'myFilter': OrderSearch(request.GET, queryset=orders),
    }

oh wait

it's a little more than that

but it seems like you're not quite following the tutorial all the way

[native tide]

no i got stuck when i got the error

    content = {
        'customer': current_customer,
        'orders': orders,
        'total_orders': orders.count(),
        'myFilter': OrderSearch(request.GET, queryset=orders),
    }

@rigid laurel it looks like that now yeah but now the whole form doesn't show up

[simple sentinel]

To double check, you do have a customer/2 right?

[native tide]

yes

i also changed the customer template to this

[rigid laurel]

def customer(request, pk_test):
    current_customer = Customer.objects.get(id=pk_test)
    orders = current_customer.order_set.all()
    filter = OrderSearch(request.GET, queryset=orders)
    orders = myFilter.qs
    content = {
        'customer': current_customer,
        'orders': orders,
        'total_orders': orders.count(),
        'myFilter': filter ,
    }
    return render(request, 'accounts/customer.html', content)```

try that maybe?

[native tide]

<div class="row">
    <div class="col">
        <div class="card card-body">
            <form method="get">
                {{ myFilter.form}}
                <button class="btn btn-primary" type="submit">Search</button>
            </form>
        </div>
    </div>

</div>```

still no form

def customer(request, pk_test):
    current_customer = Customer.objects.get(id=pk_test)
    orders = current_customer.order_set.all()
    filter = OrderSearch(request.GET, queryset=orders)
    orders = myFilter.qs
    content = {
        'customer': current_customer,
        'orders': orders,
        'total_orders': orders.count(),
        'myFilter': filter ,
    }
    return render(request, 'accounts/customer.html', content)```

@rigid laurel isn't it the same

[rigid laurel]

Sorry - I don't think I can really help. My best suggestion is to take a step back and try from scratch. I haven't worked with the Django filters at all myself really

[native tide]

😫

[rigid laurel]

Honestly, this seems like a bad tutorial. The guy jumps about too much and doesn't explain things too clearly. You're on part 12, so you probably don't want to swtich - but if you do, I'd recommend checking out Corey Schafer's videos (linked to in !resources)

[native tide]

oh

i actually moved from corey schafer's to this one cuz i encountered an error on his tutorial which i've been posting to this python server for two days so i moved to this tutorial @rigid laurel

i'll start all over then

[rigid laurel]

I'm surprised you had such poor luck with the Corey Schafer stuff

I've heard he's very good

[native tide]

Corey Schafer does explain better tbh.

[rigid laurel]

either way - keep at it if you can. It might feel like you're making no progress, but even this stuff where you're running into walls, you probably are learning things

[native tide]

ye i know there was a problem on my end no one could help me with so i moved on to a different course.

[simple sentinel]

What error did you get with Corey Schafers? I'm running through parts of it now and it's been fine

[native tide]

admin page error

i couldn't add new users to the db

[simple sentinel]

What error did you get with adding new users?

[native tide]

i forgot i'll go check

i get this error @simple sentinel

OperationalError at /admin/auth/user/add/
no such table: main.auth_user__old```

when i try to add a new user

[ocean sigil]

Which version of django you use ?

[native tide]

[native tide]

can you help me with my problem?

[real hare]

What's the issue @native tide

[native tide]

it's up there it got overwritten

[nimble epoch]

From Stackoverflow:

Quick note for people still finding this old issue: This case can also be caused by a ForeignKey/ManyToMany/OnetoOne that uses a string as reference that is invalid (eg: not correctly pointing to a model).

I was updating/refactoring a project and ran into this. Turned out it was just a typo.

Kinda weird django doesn't notify clearly it cannot resolve the string, could be because other apps confused it.

And here an example:

image = models.ForeignKey('core.image', related_name='post', blank=True, null=True)

image = models.ForeignKey('core.Image', related_name='post', blank=True, null=True)

Maybe something is wrong in your code like:
core.image, core.Image exactly like example above.

[native tide]

i have no idea where this error comes from

no

maybe yur right it points to something wrong or something

[nimble epoch]

It can be related to the relationships in your models

MAYBE

[native tide]

https://repl.it/@Beefykenny/DjangoViews

It all becomes very unclear sinds i am a noob a Django

I have a question. I am creating a store where users can sign up, and sell digital products. Now all the payments are processed with Stripe, although I do plan on adding crypto currency and paypal eventually. Right now I have it setup so the user has to enter their Stripe API Keys.

My question is; do you think I should think of another way to do this? Even though I have instructions on how to obtain your API keys, I feel like some users won't be the brightest and may have trouble.

https://gyazo.com/6f8c52de6fc28398c88f32ee332f140f?token=f00d09e39d11f9c8e465b505ba3f59b5

[cold anchor]

have a link to a helpdoc article on how to do it

[past cipher]

I actually just decided to scrap this

and instead use Stripe connected accounts instead

[past cipher]

@seller_bp.route('/dashboard', defaults={'token': None, 'account_id' : None}, methods=['GET'])
@seller_bp.route('/dashboard?code=<account_id>&state=<token>', methods=['GET'])
@login_required
def seller_dashboard(account_id, token):
    if account_id != None:
        print(account_id)

when the url is /dashboard?code=<account_id>&state=<token> its not printing the account_id

[07/Jun/2020 22:28:51] "GET /dashboard?code=ac_HQMmNm43YNSx67v45hZzDUdpl5lAOoZa&state=Ktdz9C0UfJhxsPBrF0nn46u8a02kvLqi03 HTTP/1.1" 200 -

I am not sure how to achieve what I want. Does anyone here work with Flask?

[cold anchor]

never seen a flask route include query params in it, I usually do flask.request.args.get('code') if I want to get code out of the query params

[warm igloo]

Right, so @cold anchor has it right. You either need to do it as a route /dashboard/<account_id>/<state> which is weird in this context since your params are filters really (though this format is appropriate for certain routes obviously when designing say REST APIs).

So @past cipher Flask won't count anything after the ? as part of the route signature so those are functionally identical (so really they're both just /dashboard and you get them with request.args like @cold anchor shows above.

@seller_bp.route('/dashboard', defaults={'token': None, 'account_id' : None}, methods=['GET'])
@login_required
def seller_dashboard():
    account_id = flask.request.args.get('account_id')
    token = flask.request.args.get('state')
    if account_id != None:
        print(account_id)

[celest torrent]

I can't get an easy answer from the docs. What's the purpose of instance in django forms like this?

[cold anchor]

could you post the code of one of those two form classes? it might not be from the Django itself, but could be custom code?

[celest torrent]

@cold anchor Sure.

class ProfileUpdateForm(forms.ModelForm):
    class Meta:
        model = Profile
        fields = ["avatar"]

[cold anchor]

where does forms.ModelForm come from? is that a django import?

[celest torrent]

Yeah, that just comes from

from django import forms```

[cold anchor]

ah, found the answer

looks like model forms pull data out of the model instance and pass it to the form https://github.com/django/django/blob/master/django/forms/models.py#L288-L294

the base form then gets passed that data as initial_data which gets assigned to self.initial and gets pulled out here https://github.com/django/django/blob/38a21f2d9ed4f556af934498ec6a242f6a20418a/django/forms/forms.py#L482-L490

(I'm guessing) to populate the initial form values on page load

I don't use django though so I'm not too sure

[celest torrent]

(I'm guessing) to populate the initial form values on page load
@cold anchor I think you're right. Both of these forms are used to update existing information

Add a where clause where your current user id == Post.user_id?

[native tide]

thanks @warm igloo I have a channel now. once ive typed a few things - what do I do next?

[distant trout]

OH, didnt think of that. ill try and figure that out, thanks @warm igloo

[warm igloo]

@native tide wait and hopefully someone will be along to help you -- which channel is yours, I'll give it a look but the help channels are routinely looked at and that's why the system is set up. So much noise in topic chats that requests for help can be overlooked so the help channels help elevate those.

@distant trout Roughly db.session.query(Post).delete().where(Post.user_id==current_user.id)? Sorry, I don't use SQLAlchemy often and write my own SQL.

I should probably practice with SQLAlchemy honestly if only to help more people as it comes up so often haha.

[native tide]

and then you can parse

@warm igloo thanks for your reply. The problem I am having is I get redirected from stripe, and the url is /dashboard/connect/?code=ac_HQbTLu7ek5Teodzh30378vVjTZz6Dvqg&state=JG30QDALasNHt0LsFbwzEBQBDWy3NkNy0U

But flask won't work with the ? inside the url

@seller_bp.route('/dashboard/connect/code=<account_id>&state=<state>', methods=['GET']) works fine
but
@seller_bp.route('/dashboard/connect/?code=<account_id>&state=<state>', methods=['GET']) does not

nevermind I fixed it by doing /dashboard/connect and then using request.args

anything after query ? is ignored as part of route and only accessible via request.args

I have a flask app and I want to make it scalable. other than switching to django/other frameworks, how can I make it scale horizontally? and do flask blueprints help with scalability? to me, they just look like a way to organize code better

scale how?

[jaunty zinc]

when I say scale horizontally I mean many concurrent users

[zealous siren]

generally by multiple instances behind a load balancer

Hello everyone. Anyone is familiar with some good Tutorial with Django Rest Framework and imageField? I have a model Called Image and one called Product, and i have created a one-to-many relations

but i don't know how to serialize it

I have looked at the Documentation, but there is no serialization field for images

[cursive dirge]

@opaque vigil django-rest-framework.org/api-guide/fields/#imagefield you're welcome 😉

[opaque vigil]

Yes, I am using that, but I don't know how to use it in my serializer as a related object.

https://github.com/eonbre/DogApi/blob/master/MyfinalProject/Breed/serializers.py

Here is what i have tried

In my admin panel everything works fine. On a dog instance you can upload multiple images, and a name, but i need it to work with serializers

So i could create a details page

I have tried something like this: https://www.django-rest-framework.org/api-guide/relations/

[cursive dirge]

I don't know your code but it seems that your serializer needs you to override functions to do what you want to do

it's to specific to be handled by the generic model serializer

[opaque vigil]

Are you familiar maybe with some tutorial with django rest framework and images?

[native tide]

Yes I'm now @native tide . Shouldn't you use the jinja syntax to enter values in the HTML template?

[hidden pier]

logic mostly to views.py

[native tide]

Basicly your logic is in the views.py

[hidden pier]

aka controllers

[native tide]

Can you make py classes?

[hidden pier]

sure

[native tide]

Ok good

[hidden pier]

there are Class Based Views

love them

[native tide]

I would want it to example do the following

[hidden pier]

I personally recomend this site: https://ccbv.co.uk/

[native tide]

/launch/set

/launch/get

etc...

[hidden pier]

nice sum up of class based views

you can make class based view and implement methods for each HTTP method

e.g. def get()... will handle HTTP GET etc, all can be done

[native tide]

can i get a HTTPResponse Route

like example get path would be /launch/starlink 7

[hidden pier]

request.path or something

[native tide]

Alright Awesome

Im guessing its more simple than laravel

[hidden pier]

but you would probably want to look at urls.py

there is all routing magic

you type paths and give views which ought to handle the logic https://docs.djangoproject.com/en/3.0/topics/http/urls/#example

[native tide]

path('articles/int:year/', views.year_archive),

so basicly int:year is the ID

[hidden pier]

like example get path would be /launch/starlink 7
@native tide path('starlink/<int:id>/', views.some_starlink_view),

[native tide]

so i'd need to do string:launch

[hidden pier]

yep

[native tide]

cause starlink 7 is not a int

[hidden pier]

I was already typing that for ya 😉

oh

https://docs.djangoproject.com/en/3.0/topics/http/urls/#path-converters

[native tide]

look at https://automatedtek.net/launch/Starlink 7

[hidden pier]

<str:id>

[native tide]

for example

[hidden pier]

python string type is str 🙂

[native tide]

True

🤣

I still get mixed up

[hidden pier]

no worries, I do python + JS

hard time

true vs True

[native tide]

Hopefully i can fully migrate my site to Python

I really love the programming language

It seems faster to code

[hidden pier]

Oh yeah, Django does a lot for you

anyway, good luck 😉

[late gale]

Hey I am using django i was making an Arabic version for my website I installed gettext and i ran the code django-admin startmessages -l ar so it created the folder for me I translated the words that i want and after i finished i ran django-admin compilemessages and I changed the language code in the settings.py from en-us to ar this should work and the translation should come in action but the problem it doesn't no translation take an action and thanks for your help
@late gale I don't think this would work. Did you define LANGUAGES in settings.py?

[native tide]

Made it work 😄

[hidden pier]

👏 🙂

[celest torrent]

How do I access this in a Django view?

[late gale]

@hidden pier Nope , should I and shall it be defined as a list like this

LANGUAGES = [ 'ar , 'en' ]

or ?

[late gale]

@celest torrent That's pagination you can access its view by the from the post view in your views.py

@hidden pier I fixed it

You know what was the problem

Single quotes instead of double quotes

LMAO!!!

[native tide]

Im Operational 😄

Our main website just got pushed a git and we're now running 100% Python

[arctic fog]

Hello, I am using pythonanywhere to host my flask website. My websites runs a separate python file (the file is 500 lines long) perfectly on localhost. When I host my website on pythonanywhere, I get a 500 internal server error. I'm guessing it's from overloading. Is there any way to fix this issue? Any help would be greatly appreciated.

[late gale]

try to make ur DEBUG = True so you can see the issue

@arctic fog

[native tide]

I am trying to access a user page here```python

@login_required(login_url='login')
@allowed_users(allowed_roles=['customer'])
def user_page(request):
orders = request.user.customer.order_set.all()
total_orders = orders.count()
delivered = orders.filter(status='Delivered').count()
pending = orders.filter(status='Pending').count()
content = {'orders': orders,
'total_orders': total_orders,
'delivered': delivered,
'pending': pending
}
return render(request, 'accounts/user.html', content)

[arctic fog]

I already have my debug enabled in my flask app, but doesn't seem to be working. @late gale

[native tide]

this is the user or customer model

class Customer(models.Model):
    user = models.OneToOneField(User, null=True, on_delete=models.CASCADE)
    name = models.CharField(max_length=200, null=True)
    phone = models.CharField(max_length=200, null=True)
    email = models.CharField(max_length=200, null=True)
    date_created = models.DateTimeField(auto_now_add=True, null=True)

    def __str__(self):
        return self.name```

[late gale]

@arctic fog Try to see this
https://stackoverflow.com/questions/14993318/catching-a-500-server-error-in-flask

[native tide]

and here i have a decorator

def admin_only(view_func):
    def wrapper_func(request, *args, **kwargs):
        group = None
        if request.user.groups.exists():
            group = request.user.groups.all()[0].name
        if group == 'customer':
            return redirect('user_page')
        if group == 'admin':
            return view_func(request, *args, **kwargs)
    return wrapper_func```

this is the user template

{% extends 'accounts/base.html' %}

{%block content %}
{%  include 'accounts/status.html' %}

<div class="row">
    <div class="col-md">
        <div class="card card-body">
            <table class="table table-sm">
                <tr>

                    <th>Category</th>
                    <th>Date Orderd</th>
                    <th>Status</th>
                </tr>

                {% for order in orders %}
                <tr>
                    <td>{{order.product}}</td>
                    <td>{{order.product.category}}</td>
                    <td>{{order.date_created}}</td>
                    <td>{{order.status}}</td>
                </tr>
                {% endfor %}
            </table>
        </div>
    </div>
</div>
{%endblock%}```

and when i try to log in with the new user

and try to access the user page

i get this error:

RelatedObjectDoesNotExist at /user/
User has no customer.

[late gale]

Catch the error try to say in ur views if user dont have a customer then catch the error and create it

@native tide

[native tide]

i am following along with a tutorial

and i am doing the same stuff as the course teache

so i don't know why it won't work for me

[late gale]

I think i mentioned that u can catch the error and create it if he is not exist

here
from django.core.exceptions import ObjectDoesNotExist

try to catch it

gonna give an example

[native tide]

i tried deleting with which i tried to log in at the admin URL

[arctic fog]

Thanks, I will look into it! @late gale

[native tide]

but now get this error

__str__ returned non-string (type NoneType)```

but where should i catch

it

[late gale]

it has nothing to do with that

[native tide]

i'm not even sure where the erro comes from

[late gale]

am i invisible to you

[native tide]

i see you as bright as day

yes

i did what you said alright

i figured out that the user didn't actually register

thx

I created two by accident

one blank and one filled with user

and logged in with the blank one

Sorry if i mad you mad or anything👍🏼@late gale

[late gale]

np its okay

glad it works

[mint umbra]

I apologize if this question is a bit too general, but I have a textarea that the user types in on my website. I want to implement a "WPM" counter, but I am not completely sure how I would do this. Any help would be greatly appreciated!

[cold anchor]

if you had a stopwatch, a pen, and a piece of paper how would you do it?

like, without code, what are the steps?

[mint umbra]

@cold anchor sorry for the late response. Probably record the number of words I typed and divide by the number of minutes typed, or the number of letters typed divided by 5, divided by the amount of minutes typed. However, I'm not sure how I would get this to work on my site.

[cold anchor]

ah, okay, well it might help to know that you can set a timed function in javascript

const countWPM = () => { ... }
setTimeout(countWPM, 1000 * 60 * NUM_MINUTES)

then you can use JS to grab the textarea's contents and count the words (or letters divided by 5) and divide that by the time that passed

[cosmic kraken]

Does anyone if it's possible to make a Chrome extension in Python?

[mint umbra]

@cold anchor ok thanks! will keep that in mind. Sorry for asking multiple questions, but what are the 1000 and 60 numbers there?

[cold anchor]

no worries, the second argument is the number of MS to wait to call the function https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/setTimeout so 1000 * 60 makes one minute

the frontend for all browser extensions are written in JS, but the backend can be in python

[mint umbra]

I see

I'm very new to JS

thank you for all your help!

[cold anchor]

no problem!

[distant trout]

https://i.imgur.com/ozKJeDz.png

someone know why this is happening?

class ContactForm(FlaskForm):
    name = StringField('Name', validators=[DataRequired()])
    email = StringField('Email', validators=[DataRequired(), Email()])
    message = TextAreaField('Message', validators=[DataRequired()])
    submit = SubmitField('Send Message')

[cold anchor]

what's the view function code?

[distant trout]

what you mean? the route?

@main.route('/contact')
def contact():
    form = ContactForm
    return render_template('contact.html', title='Contact Me', form=form)

[cold anchor]

you're not instantiating your form

ContactForm()

not ContactForm

[distant trout]

oh wow..

didnt even see that

[cold anchor]

in fact, you want to use form = ContactForm(flask.request.form)

to allow values to repopulate when submitted with values that don't validate

[distant trout]

ahhh okay

thanks a lot!! @cold anchor

[cold anchor]

no problem!

there's a couple more things you want to do actually, let me just pull up a quick example

[distant trout]

oh alright

[cold anchor]

@blueprint.route('/formpage', methods=['GET', 'POST'], strict_slashes=False)
def myformpage():
    form = LoginForm(request.form)
    if request.method == 'POST':
        if form.validate_on_submit():
            return redirect(url_for('app.render'))
        else:
            flash_errors(form)
    return render_template('showform.html', form=form)

flash_errors is a custom function that helps to display wtform errors

[distant trout]

oh

so it would display error if the user puts in something invalid?

[cold anchor]

from flask import flash

def flash_errors(form, category='warning'):
    """Flash all errors for a form."""
    for field, errors in form.errors.items():
        for error in errors:
            flash('{0} - {1}'.format(getattr(form, field).label.text, error),
                  category)

yeah

and flask has some builtin stuff to flash a message that you can put in a template

[distant trout]

oh

could u explain to me what this is doing if request.method == 'POST':

when the user sends the msg it is using POST?

[cold anchor]

when a <form> element gets submitted, the default HTTP method is POST

[distant trout]

ahh

awesome, im going to experiment with those code! again, thank you

[cold anchor]

no problem, last thing to put in the template to show the flashed messages:

{% with messages = get_flashed_messages(with_categories=true) %}
    {% if messages %}
    <div class="row">
      <div class="col-md-12">
        {% for category, message in messages %}
        <div class="alert alert-{{ category }}">
          <a class="close" title="Close" href="#" data-dismiss="alert">&times;</a>
         {{message}}
        </div><!-- end .alert -->
        {% endfor %}
      </div><!-- end col-md -->
    </div><!-- end row -->
        {% endif %}
    {% endwith %}

[distant trout]

this goes in the layout template, am i correct

or does it go on the template of the page itself

[cold anchor]

customize the HTML as you want but the key is get_flashed_messages which you can use in the jinja context

any one you want the messages in, I usually put it in the layout

[distant trout]

oh, ill do just that. thanks

[mint umbra]

hello, I have a quick question. I have two divs that are being updated very quickly on my site. My code makes them show numbers. However, I am also trying to get them to show something like "seconds" after the number. Sorry if my explanation is a bit unclear

if I just try

<div class="timer" id="timer">0</div>seconds

the "seconds" goes on the next line and (because it isn't in the div) isn't affected by my "timer" css.

does anyone know of any way that I might include an extra word like this?

[cold anchor]

<div class="timer"><span id="timer">0</span> 
 seconds</div>

div's default display is "block"

so you can either change that (to inline, or inline-block)

or you can add an element inside that is default inline-block styled (like a span)

[mint umbra]

this solved my issue, thanks!

Hi I was working on flask docker uwsgi nginx application, I am getting this error, work fine for small apis like return string in response but gives error for one api
*1 upstream prematurely closed connection while reading response header from upstream

new to uwsgi nginx deployment

Is it because of nginx timeout or uwsgi timeout?

Does anyone know any good courses to learn rest apis with django?

[native tide]

I can recommend the manga guide to databases

But that's a book

Only if you enjoy reading manga obviously, but the Manga Guide series is really nice as an introduction to many subjects

[quick cargo]

that sounds like an amazing idea for tutorials

Manga + Comp sci stuff

[native tide]

Those that I've read were all pretty decent

I've got the Databases, Calculus and Linear Regression Analysis

They all do a good job at introducing the topics to you and teaching you the basics

which reminds me I should figure out where I put the calculus one and reread it

Or find a better book, cause the script from my lecture is really not suitable for learning

[verbal obsidian]

You have plenty of tutorials

any will do

database normalization is generally a 'begginers topic'

not that complex

[sudden crest]

so I have a slightly strange plan

I want to see if it's possible to conduct Single Sign On over HTTP, not HTTPS

between a local application and a remote server, without a domain

so the current plan is that the local application triggers the Google (for example) login flow, and obtains an ID token

it then signs a JWT with that token (the JWT payload is a message which the user wants to send to the server, as well as the user id that the user wants to authenticate as)

the idea is then that the server figures out what the client token should be based on the transmitted user id, then verifies the JWT against that token

the issue is that normally the oauth flow is that you can verify a user token, but not necessarily arbitrarily determine the valid SSO token without knowing it

[distant trout]

can someone help me with bootstrap cards? I want to make it so the cards are side by side instead of being in a line

https://i.imgur.com/UooGtMf.png

this is how its right now

i want the bottom card to the right of the first card

here is the code https://i.imgur.com/4nBe1oZ.png

[warm igloo]

You need to put them in the grid then.

Using bootstraps row/col classes.

[distant trout]

so I have to put all the cards inside a div with the rows/col?

[warm igloo]

Not necessarily a div but yes.

Since you’re already using bootstrap might as well use their grid classes. And then you can drop that online style too.

Unless you still need it.

[distant trout]

ahhh i see

thank you 👍

[thorny geyser]

what are the best open source flask projects?

[native tide]

Awesome am i doing it correctly?

Cause idk it seems weird to do a sys.path.append

Basicly im making my own library

[native root]

Since this seems to be django, I'd strongly suggest looking into django's "import_path" functionality, and importantly importing when the server starts and not on every request like you're doing there
