Using autocomplete feature in Django admin without showing related model in the left sidebar
My main model ObjetArchi has several related models, connected through foreign keys. To avoid loading a long list of values and scrolling infinitely through it, I'm using the autocomplete feature in the ObjetArchi admin interface. Related models have to be registered for the autocomplete to work, but I'd like them not to be shown in the left sidebar. Is there a way to hide them while still being able to edit them through the main model if needed? -

How to use Django Nginx Application with both HTTP and HTTPS requests?
I have a Web Application that uses Django as backend and Nginx along with Gunicorn for the reverse proxy. I have already set up the Nginx configuration and it works perfectly when requests are sent over HTTPS. But it fails when HTTP requests are made. I want the application to work for both HTTP and HTTPS requests. Some of my Django Views contain internal requests that are made over HTTP as they have to be compatible with the Development as well as Production Server class LoginView(APIView): ... http_host = request.META["HTTP_HOST"] url = f"http://{http_host}/o/token/" headers = {'Content-Type': 'application/x-www-form-urlencoded'} data = { 'username': req_data['username'], 'password': req_data['password'], } response = requests.post(url, headers=headers, data=data) ...

DjangoRestFramework ModelSerializer ignores required extra data
I have some ModelSerializer like: class MySerializer(serializers.ModelSerializer): x = serializer.IntegerField(required=True, write_only=True) class Meta: model = MyModel fields = (...some MyModel fields..., 'x') x is not a MyModel field. Problem: when I send request without x in form_data, drf doesn't raise "required" error. Expected: 400 response with message of missed 'x' is required.

Add new entries to the model incrementing the latest value with three digits
I have a model, with a column named reference. Each reference has values like this: 106739D/4115110 106739D/4115111 106739D/4115112 and so on... From my view, I send a count of previous projects to the template, like this (truncated): def add_new_project(request, pk): context = {} projects = Project.objects.all().filter(project_id=pk).count() context['projects'] = projects Then in my template, I retrieve some value like 106739D/41151 + 1 (from count) = 106739D/411511 Template: <div class="col-sm"> <input type="text" name="reference" class="form-control" value="{{ some_given_value }}{{ projects }}" required> </div> It actually does the job, it increments the value one by one each time I create a new project, but I've been requested to do it with this format 00X: 106739D/4115110 --> 106739D/411511000 106739D/4115111 --> 106739D/411511001 106739D/4115112 --> 106739D/411511002 So basically I need to add 00X instead of X. Is there any efficient - pythonic way to do that? -

How to run Celery container without starting multiple Django servers
My docker-compose setup has several services. The ones I am concerned about are: celery, celery_beat, and backend (django). Every tutorial I have found online has the celery container using the same image as backend. The problem is that it is forcing 3 django containers to fire up (which can't be the optimal way of deploying my app). I currently use an ENTRYPOINT bash script at the end of my Dockerfile which waits for the database to be ready, then it handles migrations, then runs the development server: Dockerfile FROM python:3.9.5-alpine WORKDIR /backend ENV PYTHONDONTWRITEBYTECODE 1 ENV PYTHONUNBUFFERED 1 RUN apk update RUN apk add gcc musl-dev python3-dev libffi-dev openssl-dev postgresql-dev COPY ./requirements.txt /requirements.txt RUN pip install --upgrade pip RUN pip install -r /requirements.txt COPY ./entrypoint.dev.sh /entrypoint.dev.sh COPY . /backend/ ENTRYPOINT [ "/entrypoint.dev.sh" ] entrypoint.dev.sh #!/bin/sh if [ "$POSTGRES_DB" = "digibrain_db" ] then echo "-------------- Waiting for postgres... -------------------" while ! nc -z $POSTGRES_HOST $POSTGRES_PORT; do sleep 0.1 done echo "-------------- Postgres database started! ----------------" fi python3 manage.py makemigrations python3 manage.py migrate python3 manage.py collectstatic --no-input --clear python3 manage.py runserver 0.0.0.0:8000 exec "$@" Since the ENTRYPOINT file/command is causing all 3 containers to run django I tried to change it to … -

Here is the log: 2022-01-14T04:51:29.245939+00:00 heroku[web.1]: Starting process with command `python manage.py runserver 0.0.0.0:42836` 2022-01-14T04:51:30.238629+00:00 app[web.1]: Traceback (most recent call last): 2022-01-14T04:51:30.238658+00:00 app[web.1]: File "manage.py", line 11, in main 2022-01-14T04:51:30.238659+00:00 app[web.1]: from django.core.management import execute_from_command_line 2022-01-14T04:51:30.238659+00:00 app[web.1]: ModuleNotFoundError: No module named 'django' 2022-01-14T04:51:30.238660+00:00 app[web.1]: 2022-01-14T04:51:30.238660+00:00 app[web.1]: The above exception was the direct cause of the following exception: 2022-01-14T04:51:30.238660+00:00 app[web.1]: 2022-01-14T04:51:30.238660+00:00 app[web.1]: Traceback (most recent call last): 2022-01-14T04:51:30.238661+00:00 app[web.1]: File "manage.py", line 22, in <module> 2022-01-14T04:51:30.238661+00:00 app[web.1]: main() 2022-01-14T04:51:30.238661+00:00 app[web.1]: File "manage.py", line 13, in main 2022-01-14T04:51:30.238662+00:00 app[web.1]: raise ImportError( 2022-01-14T04:51:30.238672+00:00 app[web.1]: ImportError: Couldn't import Django.

Django redirection errors
I currently have an issue using my button as I need to open a modal which is successful but when clicking from other pages it needs to redirect back to the page it was clicked on. <button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#editProfile">+</button> I have tried return redirect(request.META.get('HTTP_REFERER')) which does stay on url but I need to use context['is_post'] in case it fails to reopen up the modal which should be passed. So currently if I used mine it'll reopen on false data but won't hold the page url. context['nmenu'] is what is used to make sure the a tag is currently active. views.py: def index(request): context={} context['is_post']= False editProfileForm = UserProfileForm() if request.method == "POST": if 'editProfileForm' in request.POST: editProfileForm = UserProfileForm(request.POST or None, request.FILES or None,instance=request.user) if editProfileForm.is_valid(): editProfileForm.save() editProfileForm = UserProfileForm() context['editProfileForm'] = editProfileForm return render(request, "home.html", context) else: context['is_post'] = True context['editProfileForm'] = editProfileForm return render(request, "home.html", context) else: # Checks if user is logged out or in and passes to form if request.user.is_authenticated: Inbox = Messages.objects.filter(Q(sender=request.user) | Q(receiver=request.user)).order_by("-time", "read") context['Inbox'] = Inbox unreadMessagesCount = Messages.objects.filter(Q(receiver=request.user) & Q(read=False)).count() context['unreadMessagesCount']=unreadMessagesCount editProfileForm = UserProfileForm(instance=request.user) context['editProfileForm'] = editProfileForm context['nmenu']='home' return render(request, "home.html", context) html: {% block content %} <div class="col-md-3" … -
Why do I need to call (Django's)object before I link it to another object in Windows powershell?
I intuitively feel that, but I don't understand it step by step. Example: In Windows Powershell I open my main folder with manage.py and open the shell with: python manage.py shell. Then I need to write something like: Product.objects.get(id=1), so later I can link this to an object: obj = Product.objects.get(id=1). My question is, why does the shell need to have it in this fashion. Why I can't to type just obj = Product.objects.get(id=1)? Without this part before: Product.objects.get(id=1). I wonder about it, because the second part of this code points out to class and method. -
How to test a URL in Django?
I wrote this detail view: def blog_detail(request, pk): blog = get_object_or_404(Blog, pk=pk) comment = blog.comment_set.all() paginator = Paginator(comment, 2) page_number = request.GET.get('page') page_obj = paginator.get_page(page_number) context = { 'blog': blog, 'page_obj': page_obj, } return render(request, 'blog/blog_detail.html', context=context) Here's the url: urlpatterns = [ path('blog/<int:pk>/', views.blog_detail, name='blog-detail') ] Here my test for the view: class BlogDetailViewTest(TestCase): def setUp(self): user = User.objects.create(username='user01', password='123456') author = Author.objects.create( user=user, date_of_birth='1998-09-08', bio='I am user01') topic = Topic.objects.create(name='Testing') blog = Blog.objects.create(title='My blog', content="It's my blog") blog.author.add(author) blog.topic.add(topic) for c in range(3): Comment.objects.create(blog=blog, user=user, comment='I am testing') self.blog_instance = Blog.objects.get(id=1) def test_url(self): response = self.client.get(f'/blog/blog/{self.blog_instance.pk}') self.assertEqual(response.status_code, 200) def test_url_name(self): response = self.client.get(reverse('blog-detail', kwargs={'pk': self.blog_instance.pk})) self.assertEqual(response.status_code, 200) The test_url function are returning this assertion error: AssertionError: 301 != 200 Why the test_url function are returning the status code 301 if the test_url_name function are returing the status code 200? Both are the same url, I don't understand.
