Calling class view inside of another class view in Django
I have JobCreateViewV1 (old one) view class which works with model in one way, and after upgrade, i created JobCreateViewV2 (new one) class that adds another entry to another model entry of first call. What is the best way to get response form first class and pass it to the second one? Here are my classes: JobCreateView class JobCreateView(AuthenticatedView, generics.GenericAPIView): #some seralizer serializer_class = JobSerializerForUser def post(self, request): #....yada yada yada... job='model is here' return Response(status=status.HTTP_201_CREATED, data=self.serializer_class(job, many=False).data) and JobCreateViewV2 class JobCreateViewV2(AuthenticatedView, generics.ListAPIView): serializer_class = ResponsibleTechnicianSerializer def post(self, request): JobCreateViewV1Response = JobCreateViewV1.post(self, request) # ...yada yadayada... #and here JobCreateViewV1Response equals to {} Old url works perfect, but when i call V2 one, data portion of response from V1 calls equals to {}. Might this problem occur because i call JobCreateView in improper way and serializer is not working the way it should? I've tried to use ShowAppsView.as_view()(self.request) approach, but it seems is not what i need. -
Django: ImageField sets wrong url
I am new to django and set up my first project with one app in the beginning. Some time later I figured out that I need a custom user model so I've created a second app with the custom user model as I've read somewhere that you need the user model as first migration (I'm telling this, because I believe my project structure is causing my problem). Right now I am working on an avatar upload for the user model. I am able to upload an image via DRF and then open the image in my browser, but not with the saved url in my database. Django saves the image like this in the database: http://localhost:8000/api/users/<user_id>/media/avatars/image.jpg. But the correct url would be: http://localhost:8000/media/avatars/image.jpg How do I make django save the correct url? I've set MEDIA_ROOT and MEDIA_URL like this: MEDIA_ROOT = BASE_DIR + 'media' MEDIA_URL = 'media/' My project structure: my project - backend (first app) - - manage.py - - settings.py - users (second app) - - models.py # here is my custom user model Any help is appreciated -
Trying to Package a DRF project with PyInstaller but getting TemplateDoesNotExist at /
I'm trying to package a DRF app as an executable with the PyInstaller library. I haven't coded much other than some basic API before testing out PyInstaller (first time working with it). What I Have Done So Far: I created hook-rest_framework.py with the following code: from PyInstaller.utils.hooks import collect_submodules hiddenimports = collect_submodules('rest_framework') I specified hiddenimports in the .spec file hiddenimports=['rest_framework.urls', 'rest_framework.apps', 'rest_framework', 'app.urls'] However, I get the following error when I initialise the executable TemplateDoesNotExist at / rest_framework/api.html I added "rest_framework" under INSTALLED_APPS in settings.py (please find it below).

From file import function (django)
I'm learning django and following a tutorial, the thing is that when I try to import a function in the file urls.py from views.py and when I run the server the cmd throws the error no module named "views", and the guy in the tutorial doesn´t get that error and doesn´t talk anything about it.

GET and POST requests in testing/ Django
Guy, I need your help. Since I'm newbie and I'm making my first app in Django I came to an issue while testing my app. There is problem with testing views, and since tested manually everything works fine problem occurs while testing automatition. I think the issue may be related to POST / GET requests because I made things in way that, most things are based on GET, even those which change things in DB. POST request is reserved only to forms. When I start tests, every action that is made seems lacking-effect like those GET requests don't work. Ok here comes the code: Views: @login_required def new(request): if request.method == "POST": player = Player.objects.get(name=request.user) hosted = Game(host=player.nick) form = CreateGame(instance=hosted, data=request.POST) if form.is_valid(): form.save() return redirect("home", name="new_room") @login_required def delete_room(request, id): game = Game.objects.get(id=id) player = Player.objects.get(name=request.user) if player.nick == game.host and game.how_many_players_ready == 0: if not game.is_played: game.delete() return redirect("home", name="game_deleted") else: return redirect('detail', id=game.id) else: return redirect('detail', id=game.id) Tests: class TestViews(TestCase): def setUp(self): self.client = Client() self.user = User.objects.create_user(username='testuser', password='12345') self.user2 = User.objects.create_user(username='testuser2', password='12345') usr = self.user self.client.login(username='testuser', password='12345') self.player = Player.objects.create(name=usr, parent = usr.username, nick = 'nie') def test_create_many_rooms(self): #this one works -> POST self.new_room=reverse('new_room') self.client.post(self.new_room, … -

Hello i am using ReactJs as my frontend for my django project. Im encountering this issue because i wish to separate my login page from my main layout.

Inlineformset with multiple children
I have a use case in which I put challenges in a model. Each challenge has 1-* vars and 1-* rounds. I want to have CRUD forms for inserting new challenges with their vars and rounds in my db. The model looks the following: class Challenge(models.Model): pass class Var(models.Model): challenge = models.ForeignKey(Challenge, on_delete=models.CASCADE) name = models.CharField(max_length=30) def __str__(self): return self.name class Round(models.Model): challenge = models.ForeignKey(Challenge, on_delete=models.CASCADE) index = models.IntegerField() description = models.CharField(max_length=100) def __str__(self): return f"[{self.index},{self.description}]" I currently use the following inlineformset to update a challenge through its pk: def updates_challenge(request,challenge_id): challenge = Challenge.objects.get(pk=challenge_id) RoundFormset = inlineformset_factory(Challenge, Round, fields=('index','description')) if request.method == 'POST': formset = RoundFormset(request.POST, instance=challenge) if formset.is_valid(): formset.save() return redirect('update_challenges', challenge_id=challenge.id) formset = RoundFormset(instance=challenge) return render(request, 'drinking_game/update_challenge', {'formset': formset}) However, this does not allow me to change the vars at the same time. I could just make a new form for the vars but that means that I have to create a seperate form for the vars and I can not save both rounds and vars at the same time. On saving I first want to apply some logic to check if the amount of vars is equal to the amount of rounds. I hope that anyone can … -

Why isn't django serving my SPA static files correctly?
I'm building a website using a Django backend and Vuejs frontend. In development I started the backend and the frontend separately with python manage.py runserver and yarn serve respectively.

However, when I run it: docker-compose exec app python manage.py shell_plus --notebook I am getting the following error: Traceback (most recent call last): File "manage.py", line 21, in <module> main() File "manage.py", line 17, in main execute_from_command_line(sys.argv) File "/usr/local/lib/python3.8/site-packages/django/core/management/__init__.py", line 401, in execute_from_command_line utility.execute() File "/usr/local/lib/python3.8/site-packages/django/core/management/__init__.py", line 395, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/usr/local/lib/python3.8/site-packages/django_extensions/management/commands/shell_plus.py", line 125, in run_from_argv return super(Command, self).run_from_argv(argv) File "/usr/local/lib/python3.8/site-packages/django/core/management/base.py", line 328, in run_from_argv self.execute(*args, **cmd_options) File "/usr/local/lib/python3.8/site-packages/django/core/management/base.py", line 369, in execute output = self.handle(*args, **options) File "/usr/local/lib/python3.8/site-packages/django_extensions/management/utils.py", line 62, in inner ret = func(self, *args, **kwargs) File "/usr/local/lib/python3.8/site-packages/django_extensions/management/commands/shell_plus.py", line 517, in handle shell() File "/usr/local/lib/python3.8/site-packages/django_extensions/management/commands/shell_plus.py", line 253, in run_notebook app.initialize(notebook_arguments) File "<decorator-gen-117>", line 2, in initialize File "/usr/local/lib/python3.8/site-packages/traitlets/config/application.py", line 87, in catch_config_error return method(app, *args, **kwargs) File "/usr/local/lib/python3.8/site-packages/notebook/notebookapp.py", line 1769, in initialize self.init_webapp() File "/usr/local/lib/python3.8/site-packages/notebook/notebookapp.py", line 1490, in init_webapp self.http_server.listen(port, self.ip) File "/usr/local/lib/python3.8/site-packages/tornado/tcpserver.py", line 151, in listen sockets = bind_sockets(port, address=address) File "/usr/local/lib/python3.8/site-packages/tornado/netutil.py", line 174, in bind_sockets sock.bind(sockaddr) OSError: [Errno 99] Cannot assign requested address -
Django If statement in HTML not responding
I am trying to show in a nav bar an option where if the user is the designer it appears to him to direct him to user-posts. I know that the link is working because in the post list and post detail when I click the user name it directs me to the user-posts, I am trying to do the same in the nav bar Here is is the template <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink"> {% if object.designer == user %} <a class="dropdown-item" href=" {% url 'score:user-posts' post.designer.username %} ">Submitted Posts</a> {% endif %} Here is the post-detail link that I am trying to imitate <a class="post_name" href="{% url 'score:user-posts' object.designer.username %}"> {{ object.designer }} </a> Here is the list view as well link to users post: <a href="{% url 'score:user-posts' post.designer.username %}">{{ post.designer }}</a> Here is the User list view class UserPostListView(ListView): model = Post template_name = "user_posts.html" context_object_name = 'posts' paginate_by = 5 def get_queryset(self): user = get_object_or_404(User, username=self.kwargs.get('username')) return Post.objects.filter(designer=user).order_by('-date_posted')
