I have created a Django project but I am using Apache as the webserver.

Django: BootstrapCDN or
I am trying to make my first website. I am using Django for it. I have a question related to inclusion of css/js from Bootstrap. What is the difference between installing it and linking it using BootstrapCDN? What happens if that link is no longer accessible ? Will it affect the website? Can't I just include those files in statics directory? I have this in base.hml file of my app: <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css"> <link rel="stylesheet" href="{% static 'flatly.css' %}"> <link rel="stylesheet" href="{% static 'main.css' %}"> <link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css"> <script src="https://code.jquery.com/jquery-1.11.3.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/js/bootstrap.min.js"></script> I am a beginner, sorry if it is too naive to ask such a question.

Django: filtering on `DecimalField` doesn't work well?
This is my model: class Tick(BaseModel): . . trade_coin_volume = models.DecimalField( max_digits=15, decimal_places=8, ) trade_price = models.DecimalField( max_digits=15, decimal_places=8, ) . .

Error in Django 2.0 tutorial, part 7 -- is this a bug
When I follow the 2.0 tutorial, on part 7, I noticed there is an error symbol under "PUBLISHED RECENTLY" in this screenshot: The "was_published_attribute" was set to True in the tutorial. But if set it to False, it can show "False" correctly. Is this a bug? Any suggestion of fixing or workaround? Many thanks! I apologize that I describe this question poorly in the title. I appreciate it if anyone can suggest me a better title. -
Why is Django's authenticate taking too long to resolve?
I have a Django project that uses Django Rest Framework and its @list_route among others to make api calls from my front-end. The very first api call I make is: website.com/api/staffs/authenticate The endpoint code that catches that is: @list_route(permission_classes=(AllowAny,)) def authenticate(self, request): if request.user.is_authenticated: if is_staff_or_admin(request.user): return Response(StaffSerializer(request.user).data) data = {'detail': AuthenticationFailed.default_detail} return Response(status=status.HTTP_401_UNAUTHORIZED, data=data) That block of code takes a whopping 30-42 seconds to resolve! Any idea what might be causing this slowdown? -

What is the advantage of using a Django bootstrap module over linking to bootstrap files directly?
I see there are Django bootstrap modules (e.g. crispy_forms, django_bootstrap). I am trying to decide whether to use a module or link directly to bootstrap files in a base html file like the following: <!-- jQuery library --> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <!-- Latest compiled JavaScript --> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script I have an understanding that with the modules I would do the styling in the code. With using bootstrap directly, I am thinking I have to style it in the template files. I am trying to see reasons why I should be using a module. Also, with the bootstrap modules would I be able to use all bootstrap features? -

Publish Messages to Exchanges in RabbitMQ with Celery
I have written a Django-Project which cues different tasks async via my_task.delay(). The problem is as the project is getting bigger it is really difficult to route the tasks properly - I started to write tasks which only purpose is to combine different tasks, which makes the code messy after some time. As I was reading some RabbitMQ documentation I came around a solution which could structure my project a lot better which relies on Exchanges. Exchanges can publish messages to multiple queues on which a Cosumer can consume it, in short: The RabbitMQ-Documentation describes a solution with Pika, which is a more low-level Client for RabbitMQ than Celery. The Celery-Documentation describes this scenario in its Documentation but doesn't describe how to create a Producer which produces Messages which are sent to an Exchange which distributes it to various Queues as seen in the Picture above. It only describes how to message Queues and send tasks - but I want this handeled by the Exchange. I found that Kombu, on which celery relies under the hood, has a function to send messages to an Exchange via a Producer but I can't find any documentation how to use this in celery-django. … -

How to reference a ForeignKey using a population script with Django

Why am I unable to serialize my query via DRF?

Making a Django form appear on click

Retrieve a script variable in all apps - Django
I've been searching and trying several solutions for a what it seems a simple problem for data retrieval of an externally executed script in Django. Now, I've figured out how to execute a script once through the Django's "AppConfig" (Execute code when Django starts ONCE only?), but I also need to retrieve at least once the data this script gathers across all Django's applications. Since it is a "sensorial" data, It shouldn't be included in a database or stored in any other way. What is the best way to do this? What am I missing? Thanks in advance for any heads up.
