I have an app were I'm trying to make a course with modules in it, and inside the course page I want to link a page with the modules of the course in it but I get "TypeError at /modules modules_page() missing 1 required positional argument: 'id'".

request.user returning AnonymousUser in ModelViewSet, but working properly in APIView
I am trying to customize get_queryset() in my DocumentViewSet so the GET method will return all Document objects created by request.user (currently logged in user). However, I am stuck in this error:django.core.exceptions.ValidationError: ['“AnonymousUser” is not a valid UUID.'] I assume this is caused by getting AnonymousUser as my self.request.user. The weird part is that my other APIView that deals with request.user are working flawlessly; The only difference I could find between the two is type of viewset: ModelViewSet vs APIView. Would appreciate any help! document.views class DocumentViewSet(viewsets.ModelViewSet): model = Document serializer_class = DocumentSerializer list_serializer_class = DocumentListSerializer permission_classes = (AllowAny,) # for testing, will change later def get_queryset(self): user = self.request.user return Document.objects.filter(user=user) def perform_create(self, serializer): print(self.request.user) serializer.save(user=self.request.user) document.models class Document(models.Model): id = HashidAutoField(primary_key=True) user = models.ForeignKey(User, on_delete=models.CASCADE, blank=True, null=True) title = models.CharField(max_length=100, default="Untitled") template = models.CharField(max_length=100, default="") editorState = models.JSONField(default=[]) updated = models.DateTimeField(auto_now=True) created = models.DateTimeField(auto_now_add=True) def __str__(self): return self.title user.models class User(AbstractUser): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) username = None first_name = models.CharField(max_length=100, default="unknown") last_name = models.CharField(max_length=100, default="unknown") profile_pic = models.CharField(max_length=200, default="unknown") email = models.EmailField(unique=True, db_index=True) secret_key = models.CharField(max_length=255, default=get_random_secret_key) USERNAME_FIELD = "email" REQUIRED_FIELDS = [] class Meta: swappable = "AUTH_USER_MODEL" users.api & selectors This is the APIView which … -
Cannot assign 3, must be a model instance while bulk create in django rest
I am trying to do a bulk create and update in a view. But however, when I bulk create the following error. ValueError: Cannot assign "3": "LmsGrade.exam" must be a "LmsExamModel" instance. I have done bulk_create several times before but none of the time it ask for a instance instead of id.

Django app with Plotly/Dash callback and Celery/Redis
I have a Django project where one of my apps provides interactive data visualization using Dash/Plotly and is deployed to Heroku. As my database grew bigger, the time it takes to collect the relevant data, normalize it, and plot it, is now often larger than 30s, therefore the requests are timing out and my plots are not showing up anymore, which is sad, because they were working great :/ What I'm trying to do now is to use Celery so that the data collection and normalization is dispatched to a worker and run asynchronously having Redis as a broker, but this is getting extremely confusing as I don't have any experience with these frameworks and I couldn't find an example of such an application. I'm posting below a simplified and analogous app without any Celery stuff, that works exactly how I want (the user provides a seed and the app plots a scatter plot with random numbers generated from that seed). The project tree is: djcel/ djcel/ worker/ dash_apps/ test_apps/ plot.py templates/ worker/ scatter_plot.html urls.py views.py And the main files are: plot.py from dash import dcc from dash import html from dash.dependencies import Input, Output from django_plotly_dash import DjangoDash import … -

Django Custom user model, the model saved in a separated file inside folder
I am new to Django and working on a project that needs a custom user. I created folders for models, views, URLs, and serializers. Each feature has its own file in these folders.

How to combine multiple models into one view template in django

Django Rest Framework with shortuuid, generics.RetrieveUpdateDestroyAPIView returning 404 {"detail": "Not found."}
I was remaking a social media site as a revision of Django and the rest framework, I didn't want to use the django default linear id count and didn't like how long the uuid library's ids was, so I used the shortuuid library. I've used them on the posts and the comments just to keep the anonymity of the count of both posts and comments. On the posts side everything works for the CRUD stuff (which should be proof that the issue isn't from the shortuuid library, as far as I know), although with the comments the Create Retrieve works perfectly but the Update Destroy doesn't. so here is the code we are working with: starting with the models to know what kind of data we are working with (models.py): from shortuuid.django_fields import ShortUUIDField ... # posts likes etc class Comment(models.Model): id = ShortUUIDField(primary_key=True, length=8, max_length=10) user = models.ForeignKey(User, on_delete=models.CASCADE) post = models.ForeignKey(Post, on_delete=models.CASCADE) body = models.TextField(max_length=350) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) active = models.BooleanField(default=True) class Meta: ordering = ['created'] def __str__(self): return f'on {self.post} by {self.user}' objects = models.Manager() serializers.py: class CommentSerializer(ModelSerializer): username = SerializerMethodField() def get_username(self, comment): return str(comment.user) class Meta: model = Comment fields = ['id', … -

The field oldapp.MyModel.related was declared with a lazy reference to 'oldapp.related', but app 'oldapp' doesn't provide model 'related'
Similar questions have been asked before, but none are applicable to my situation as far as I can tell. I followed this answer to move the model Related out of oldapp and into newapp. I created the following migration in oldapp: class Migration(migrations.Migration): dependencies = [ ("oldapp", "0019_merge_20220626_1439"), ] database_operations = [ migrations.AlterModelTable("Related", "newapp_related"), migrations.AlterModelTable("AnotherRelated", "anothernewapp_AnotherRelated"), ] state_operations = [ migrations.DeleteModel("Related"), migrations.DeleteModel("AnotherRelated"), ] operations = [ migrations.SeparateDatabaseAndState( database_operations=database_operations, state_operations=state_operations, ) ] Note that I'm actually moving two models into two new apps. However, MyModel only has a foreign key to Related, so I'm only going to include example code for the Related model. Also, MyModel is still in oldapp and still has a foreign key to Related. In newapp, I added this migration (0001_initial): class Migration(migrations.Migration): initial = True dependencies = [ ("oldapp", "0020_move_related_and_anotherrelated_to_own_apps"), ] state_operations = [ migrations.CreateModel( name='Related', fields=[ # ... ], # etc. ), ] operations = [ migrations.SeparateDatabaseAndState(state_operations=state_operations) ] Running migrations, I get this error: ValueError: The field oldapp.MyModel.related was declared with a lazy reference to 'oldapp.related', but app 'oldapp' doesn't provide model 'related'. I thought I could just add this to oldapp.migrations.0020_move_related_and_anotherrelated_to_own_apps: operations = [ migrations.SeparateDatabaseAndState( database_operations=database_operations, state_operations=state_operations, ), migrations.AlterField( model_name='mymodel', name='related', field=models.ForeignKey(blank=True, null=True, on_delete=django.db.models.deletion.SET_NULL, … -

Is there a preferred way to serialize external objects to json format in python

Embrassing question. I cannot seem to be able to add new models. I have list of models in my models.py file which appear in admin panel. However, the new model I am trying to add does not appear. What makes it embarrassing is that it was showing earlier this afternoon. I made some changes to the code and clearly something went wrong. I deleted the code, hoping this might resolve the problem, but no. Just in case it would be related to the actual model I was creating, I completly change the code to something simple (see below) but again no change. I am not too sure what I clicked, deleted to make this happen. Any clues? (PS: I did do the migrations.) from django.db import models from django.contrib.auth.models import User from decimal import Decimal import locale import logging ... class Event(models.Model): name = models.CharField('Venue Name', max_length=120) def __str__(self): return self.name -
Show in template fields labels names instead of fields names - Django
I use to display errors from the forms.py in template using the code below: {% for key, value in form.errors.items %} <div class="alert alert-danger alert-dismissible fade show" role="alert"> <strong>Error:</strong> {% if key != '__all__' %}{{ key|title }} {% endif %} - {{ value|striptags }} </div> {% endfor %} But my project is in a different language so I don't want to show the field name but the label name. I need something like taht {{ key.label|title }} {% for key, value in form.errors.items %} <div class="alert alert-danger alert-dismissible fade show" role="alert"> <strong>Error:</strong> {% if key != '__all__' %}{{ key.label|title }} {% endif %} - {{ value|striptags }} </div> {% endfor %} How to show label names instead of field names? -
django not using custom adapter?
Project structure myproject -- app1 -- views.py etc., myoroject -- settings (folder) -- base.py (this is the settings file django uses) -- wsgi.py -- adapter.py This is my project directory structure the issue I'm facing is the custom adapter that I created is not used by django all-auth. Not sure why this is making me so tired. I have specified the module path also still django does not call save_user method in the adapter.py file. This is my code as follows from allauth.account.adapter import DefaultAccountAdapter class UserAccountAdapter(DefaultAccountAdapter): print("class loading ") def get_login_redirect_url(self, request): print(f"GET request dict is {request.GET}") return reverse('users:home') def save_user(self, request, user, form): print("working in save user", form) user = super(UserAccountAdapter, self).save(request, user, form) return user while server reloads the print statement works but the method is not called. Django does not recognizes it. In my settings folder I have a settings file called base.py where I have mentioned the path. base.py ACCOUNT_FORMS = { 'signup': 'users.forms.UserRegistrationForm' } ACCOUNT_ADAPTER = "spotify.adapter.UserAccountAdapter" I have also placed the adapter.py file inside users app too and tried changing the path but it does not work. Would be glad if someone has encountered the same and found the solution. -
Django: URL dispatcher doesn't convert DateField to '%Y-%m-%d'
I'm a newbie with Django and I'm faced with a problem — can't convert string to datetime object and back with register_converter. I have a date as Jan 1, 2000 and I need to convert to 2000-01-01. I created converter, registered it, but in the template, I see the date as Jan 1, 2000. How could I fix it? That's urls.py: from django.urls import path, register_converter from datetime import datetime class PubDateConverter: regex = r'[0-9]{4}-[0-9]{2}-[0-9]{2}' format = '%Y-%m-%d' def to_python(self, value): return datetime.strptime(value, self.format) def to_url(self, value): return value.strftime(self.format) register_converter(PubDateConverter, 'date') urlpatterns = [ path('books/<date:pub_date>/', book_view, name='book_view'), ] That's models.py: class Book(models.Model): name = models.CharField('Name', max_length=64) author = models.CharField('Author', max_length=64) pub_date = models.DateField('Pub_date') def __str__(self): return self.name + " " + self.author That's views.py: def book_list(request): return render(request, 'books/book_list.html', {'book_list': Book.objects.all()}) And in template I substitute the value as: {% for book in book_list %} <p>Date: {{ book.pub_date }}</p> {% endfor %} I use Django version is Django==4.0.5 -
