Defining Models outside models.py

[Sam Taiwo]

Hi everyone,

I know there are currently 3 ways to define a model in Django
1) Define it directly in the models.py file
2) Define it directly in a models package in the same directory as your 
other app files
3) Define it somewhere completely different and just import the models into 
the models.py

My question is, is there a way to write a model in any arbitrary file in 
you directory and link it to your app without having to use models.py file 
or directory.
For example is there a way to write a model directly in the views file and 
then add some config to the settings or elsewhere to enable Django to know 
of it's existence and pick up any changes that happen to it.
I don't mind if it's a complete hack
Thanks

Re: Minimum Hardware requirement - reg

[Sam Taiwo]

I think think the first advice is way off base in two ways.

1) It's not clumsy to have 8 apps if that is the the structure of the
project that makes each part encapsulated and reusable.

2) 30 concurrent users in one app can be more demanding than 1000 in
another. It really depends on what each user is doing. Though it if your
site is like 99% of others you shouldn't't need to worry about hardware.

Re: Any open source project for beginner to start with ?

[Sam Taiwo]

Hi,

If you believe you are ready for open-source contribution, a good start
would be just contributing back to Django.
https://code.djangoproject.com/query?status=!closed=1=Accepted=priority

Here you can find "easy" ways to contribute. If you don't feel like you are
still up to the task, then continue to stretch yourself by building bigger
applications till you feel comfortable to come back and contribute.
I feel like Django is the best place to start, considering it will be the
framework you will have the most experience with till date.

Kind Regards
Sam

Re: Channels & WebSocket - failed: Error during WebSocket handshake: Unexpected response code: 403

[Sam Taiwo]

I'm not sure, but it looks like you are trying to connect to a localhost
which is fine locally but not in production. You probably need to change
your frontend code to route properly. This is all speculation as you have
not shown your application code, I don't think you'll get many good
answers...

Re: how to create a Django project without using an IDE, but using the django-admin startproject command

[Sam Taiwo]

Make sure your virtual environment is activated, you have to activate it
each time you create a new terminal.

Also contrary to what someone else said, you can use django-admin anywhere,
while you must be in the correct directory to run the manage.py file

Re: Django credit card redaction app - - MultiValueDictKeyError

[Sam Taiwo]

I would be careful how you pass the data on get, somewhere in your front
end code you are probably not passing the data through as you expected.
Instead of using .GET, use .GET.get to get your data. This will either
return the value you want, or none. I think you have made the error of not
passing your data to the get header as you didn't explicitly write this on
the form element. Check the URL and log the get object in Django to make
sure the data is actually appearing in both.

ChannelsLiveServerTestCase Apps are not loaded error

[Sam Taiwo]

I am trying to follow the 4 part channels tutorial, however I am getting an 
error on the last part where we run selenium to test against a live server. 
It's not the end of the world as I can still run the server with no 
problems, however it limits my ability to test which is a shame.
I have the full details in the closed issue below (to avoid repetition)
https://github.com/django/channels/issues/1207

I have somehow also managed to get these tests to run and pass with 
channels version 2.0.2 since opening the issue, however versions 2.1.6 
still fails.
I'm unfortunately not experienced enough with the packages in the error 
trace to diagnose the problem myself.
Thanks in advance, hopefully this is enough information.
I can provide more on request.
