How to allow an empty foreign key in Django?
I'm very new to Django so this may be the dumbest question ever. I have 2 models set up in django; 'Class' and 'Profile'. The 'Profile' class has a foreign key that references 'Class'. When creating a profile on the front end I am unable to leave the form blank as ("Profile.group" must be a "Class" instance.). I want to be able to create a profile that doesn't have to belong to a class. class Class(models.Model): class_name = models.CharField(max_length=5) # a few other things that don't matter def __str__(self): return self.class_name class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) # a few other things that don't matter group = models.ForeignKey(Class, on_delete=models.SET_NULL, null=True, blank=True) and in form.py class ProfileRegisterForm(forms.ModelForm): # a few other things group = forms.CharField(max_length=5, required=False) If there is anything important that I've missed out please let me know, it's my first time posting here so I don't know what the standard is. -

Django Form Wizard - Using an image formset for a related post model
So I'm using the Django Form Wizard to split a simplified PostForm. In one of the steps, visitors can upload different images related to the Post.

Unable to implement a floating button in Django template
I am trying to create a floating button as shown in this video. However I am unable to implement the same. I am basically tying to add this to one my django templates.

How do I add TypeScript files in a Django project made with Visual Studio 2019
Is it possible to use TypeScript instead of JavaScript in a Django project developed using Visual Studio? At the moment I just tried to add a .ts file and import it to a HTML file. It fails when finding non-Javascript syntax though. I was wondering what I was missing. Do I have to configuration Visual Studio for it? (TypeScript sdk is already installed). Is it going to compile the .ts files into JavaScript by itself or do I have to go through extra steps? -

django admin.autodiscover() import order on urls file
I cloned a sample app for django and run code inspection and found that admin.autodiscover is called before importing the views file, that's used for the patterns later: from django.contrib import admin from django.urls import path admin.autodiscover() import hello.views urlpatterns = [ path("", hello.views.index, name="index"), ... ] This triggers a PEP8 code style warning as the imports are not all on the top of the file. I'm afraid that moving it may have unintended side effects. Is that the case? -
