How do I put django cms plugins classes inside multiple files instead of just putting it all inside cms_plugins.py?
So I have a project where I am using Django CMS as the root of my project. First of all I'm new to Django CMS, and I now want to code some plugins to put into my pages. I searched for the solution but everywhere it says that I should put it inside cms_plugins.py. I tried creating a folder named cms_plugins and created an __init__.py file inside it. Then I created the plugin inside a file named ThePlugin.py and coded my plugin the same way I did it in cms_plugins.py. Unfortunately it's not working. If someone can help me I'd be really gratefull. Thanks. -
Is Django only good for web applications where a user logs in? [closed]
Is Django only good for web applications where a user logs in? The reason I ask is because I recently learned Django and built a website where a user could sign up, input their measurements, and the website tells them how many calories they should eat. Is there a way to build this website in a way where the user doesn't need to sign up or log in? I've seen Javascript-based exampled where data is carried from page to page using cookies but using Python / Django the only way I know how to do this is by using a database. -
How to generate newsfeed / timeline consisting of different types of contents?
I have to implement a newsfeed for an application where I need to show different types of content. And in the future, some new types of content may come. I have the following idea in my mind at a high level. At this point of time, I'm not concerned about ranking, caching, etc. My focus is to generate newsfeeds having different types of content. class ContentType1(models.Model): pass class ContentType2(models.Model): pass class ContentType3(models.Model): pass class Content(models.Model): c_type = models.CharField( max_length=6, choices=[ ('TYPE1', 'Type 1 content'), ('TYPE2', 'Type 2 content'), ('TYPE3', 'Type 3 content') ] ) type_1 = models.ForeignKey(ContentType1, null=True, blank=True) type_2 = models.ForeignKey(ContentType2, null=True, blank=True) type_3 = models.ForeignKey(ContentType3, null=True, blank=True) The idea is to have a general Content model having separate fields for every type of content and a field named c_type which determines the type of the content and guides to access the corresponding field. And responding to users' requests from the Content queryset. I'm not fully satisfied with the approach, looking for a better approach maybe something with polymorphism or any better approach using Django. -

WebSocket dosn't work with postman (django channels)

Django. Asynchronous requests are executed in only one async event loop
I'm trying to find out how to use Django 4.0 asynchronous request support. There is one very strange thing I can't understand: Django (uvicorn or asgi.py) creates only one event loop for two different views, despite the fact that I specified max_workers=8 in uvicorn settings. This can lead to a case, when we have a lot of views (ex. 100) and in this views there are a lot of CPU-bound logic (ex: conditions, loops, calculations, etc) and a lot of IO-bound logic. Using async/await we speed up and optimize all IO-bound operations, but our CPU-bound logic is slowing down our event-loop. Instead of using event-loop for every process (worker), it uses only one loop, while other workers (7) stand still. I think, it isn't a normal behavior. What do you think? Check the code below to see more details: views.py import asyncio import os import random import time from django.http import HttpResponse from django.utils.decorators import classonlymethod from django.views import View class AsyncBaseView(View): @classonlymethod def as_view(cls, **initkwargs): view = super().as_view(**initkwargs) view._is_coroutine = asyncio.coroutines._is_coroutine return view class AsyncTestView(AsyncBaseView): async def get(self, request, *args, **kwargs): r = random.randint(1,4) print('Recieved', r) print('PID = ', os.getpid()) # Simulate long code-inside operations (conditions, loops, calculations, ets) … -

Here is the configuration of my static_root variable: STATIC_ROOT = [os.path.join(BASE_DIR,'vol/web/static')] My templates are at the root of the project. TEMPLATES={ ... 'DIRS':[os.path.join(BASE_DIR, 'templates')], ... } This is how I call my bootstrap.min.css file in a project template: <link rel="stylesheet" href="{% static 'assets/plugins/bootstrap/css/bootstrap.min.css' %}"> But it doesn't work because the file is not loaded. What's the right way to do it?
