Update

Thanks to Michael I was able to get this to work perfectly in my CreateView, but not in the UpdateView. When I try to set a form_class it spits out an improperly configured error.

How can I go about filtering the ForeignKey in the updateview?

I have a feeling I'm missing something small here but I've been working on it for a while and can't figure it out.

I have an app called story universe where the user creates one with a name and description.

I then have a character creator class where the user can create a character within that universe. This all works fine, except when the user goes to create their character they see a list of all universes created by all users.

Then there are other apps that will also mimic what I'm trying to do with the character creator.

I need to limit the Story Universes to only those created by the currently logged in user.

I've tried a few different ways and had the most success with the following, but with this code, no Universe appears when trying to create a new character.

models.py:

class Universe(models.Model):user = models.ForeignKey(User,related_name='universe',on_delete=models.CASCADE)name = models.CharField(max_length=100, unique=True)description = models.TextField(max_length=2000,blank=True,default="")    def __str__(self):return self.namedef get_absolute_url(self):return reverse('universe:singleuniverse',kwargs={'pk': self.pk})class Meta:ordering = ['name']unique_together = ['user','name']class Character(models.Model):user = models.ForeignKey(User,related_name='characters',on_delete=models.CASCADE)universe = models.ForeignKey("story_universe.Universe", on_delete=models.CASCADE)name = models.CharField(max_length=255,unique=True)def __str__(self):return self.namedef get_absolute_url(self):return reverse('character_developer:singlecharacter',kwargs={'pk': self.pk})class Meta():ordering = ['name']unique_together=['user','name']

views.py:

class CreateCharacter(LoginRequiredMixin,generic.CreateView):template_name ='character_developer/character_create.html'form_class = CreateFormdef get_form_kwargs(self):kwargs = super(CreateCharacter,self).get_form_kwargs()kwargs['user'] = self.request.userreturn kwargsdef form_valid(self,form):self.object = form.save(commit=False)self.object.user = self.request.userself.object.savereturn super().form_valid(form)

forms.py:

class CreateForm(forms.ModelForm):def __init__(self,*args,**kwargs):user = kwargs.pop('user')super(CreateForm,self).__init__(*args,**kwargs)self.fields['universe'].queryset = Character.objects.filter(user=user)class Meta:model = Characterfields = ('universe','name')

You need to make a slight change to the CreateForm class in your forms.py:

class CreateForm(forms.ModelForm):def __init__(self,*args,**kwargs):user = kwargs.pop('user')super(CreateForm,self).__init__(*args,**kwargs)self.fields['universe'].queryset = Universe.objects.filter(user=user)class Meta:model = Characterfields = ('universe','name')

That will then pull through the returned Universe objects into the universe field, but only for the currently logged in user.
