Changing admin site codes to another app in Django
I am learning django I would like to move admin to another app that I created but I couldn't do and don't know how to do it. How can I move all admin site codes to another app? Simply moving or creating admin codes in that app didn't work. -
Getting a "Django can only handle ASGI/HTTP connections, not websocket." error when hosting ASGI on heroku?

How to share validation and schemas between a DRF FilterBackend and a Serializer
I am implementing some APIs using Django Rest Framework, and using the generateschema command to generate the OpenApi 3.0 specs afterwards. While working on getting the schema to generate correctly, I realized that my code seemed to be duplicating a fair bit of logic between the FilterBackend and Serializer I was using. Both of them were accessing and validating the query parameters from the request. I like the way of specifying the fields in the Serializer (NotesViewSetGetRequestSerializer in my case), and I would like to use that in my FilterBackend (NoteFilterBackend in my case). It would be nice to have access to the validated_data within the filter, and also be able to use the serializer to implement the filtering schemas. Are there good solutions out there for only needing to specify your request query params once, and re-using with the filter and serializer? I've reproduced a simplified version of my code below. I'm happy to provide more info on ResourceURNRelatedField if it's needed (it extends RelatedField and uses URNs instead of primary keys), but I think this would apply to any kind of field. class NotesViewSet(generics.ListCreateAPIView, mixins.UpdateModelMixin): allowed_methods = ("GET") queryset = Note.objects.all() filter_backends = [NoteFilterBackend] serializer_class = NotesViewSetResponseSerializer def … -
Passing a callable to the default option of a model field fails
I have a model named Package. It has fields named, diagnosis, treatment, patient_type, mf and tp. The fields diagnosis, treatment and patient_type have foreign keys defined in separate individual classes, making diagnosis, treatment and patient_type choice fields. Now, what I intend to achieve is that whenever the user chooses the treatment and patient_type from the choices, I want certain figure to appear in mf as a default value. It should be dependant on both the above fields. I have defined a function that takes treatment and patient_type as its arguments, applies the suitable conditions and returns the relevant figure. But when I assign the function to the default option to the mf field, run the migrations and open the webpage and fill in the details in treatment and patient_type, the mf does not return the desired value. What is going on here, is there something that I am doing wrongly? The models: class Diagnosis(models.Model): diagnosis=models.CharField(max_length=30, blank=True) def __str__(self): return self.diagnosis class Treatment(models.Model): treatment=models.CharField(max_length=15, blank=True) def __str__(self): return self.treatment class PatientType(models.Model): patient_type=models.CharField(max_length=15, blank=True) def __str__(self): return self.patient_type class Package(models.Model): rt_number=ForeignKey(Patient, on_delete=CASCADE) diagnosis=models.ForeignKey(Diagnosis, on_delete=CASCADE) treatment=ForeignKey(Treatment, on_delete=CASCADE) patient_type=ForeignKey(PatientType, on_delete=CASCADE) max_fractions=models.IntegerField(default=max_fraction(treatment, patient_type)) total_package=models.DecimalField(max_digits=10, decimal_places=2) The function that is added to the default option in … -

Django - Page redirect showing as empty page after saving?
I'm working through a Wiki project for CS50's web course and I'm having an issue with my edit entry implementation. I'm able to edit an entry and it saves properly but for some reason, redirecting the user to the newly edited entry is only showing an empty entry page like this: here's my views. py: def edit(request, title): content = util.get_entry(title) if request.method == "GET": return render(request, "encyclopedia/edit.html", { "title": title, "content": content }) elif request.method == "POST": title = request.POST.get("title") content = request.POST.get("content") util.save_entry(title, content) html = md_converter(util.get_entry(title)) return render(request, "encyclopedia/entry.html", { "title": title, "content": html }) else: return render(request, "encyclopedia/edit.html", { "title": title, }) and my urls.py: from . import views app_name = "encyclopedia" urlpatterns = [ path("", views.index, name="index"), path("wiki/<str:entry>", views.entry_page, name="entry"), path("wiki/edit/<str:title>", views.edit, name="edit"), path("search", views.search, name="search"), path("random", views.random_page, name="random"), path("create_landing",views.create_landing_page, name="create_landing"), path("create_entry",views.create_entry, name="create_entry") ] Is there something wrong with my redirect?

pytest fixture to make an AIPClient that I have information for
I am trying to make a fixture that returns an APIClient object that is authenticated for a user that I can pass a parameter to if I need. I have a DjangoModelFactory object called CustomerFactory that can create a customer and a user, the user of which is created with a UserFactory factory.

Accessing profile info through user model Django
Hello I am a beginner with the django python framework. I need to display a user's image and bio on a file named user_posts.html in my blog app. I have it where I can access the user's image and bio by looping over the posts for the user. However, I need it so it only displays the bio and the image once. I have a separate profile.html in a users app. In that file, I can do just src="{{ user.profile.image.url }}" and {{ user.profile.bio }} to access the users information but that does not seem to work in my user_posts.html because of the structure of my project.
