Querying a User Profile model - django

Question

I'm having trouble with this query.
Users application
models.py
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
current_story = models.PositiveSmallIntegerField(null=True)
return f'{self.user.username} Profile'
To avoid confusion, the 'current_story' will eventually be a foreign key for the Books.story model (excluded here) once I learn how to do use a foreign key across apps.
Books application
models.py
class character(models.Model):
fk_user = models.ForeignKey(User, default='1', on_delete=models.CASCADE)
fk_story = models.ForeignKey(story, default='1', on_delete=models.CASCADE)
name = models.CharField(max_length=100, default='', null=True)
def __str__(self):
return self.name
class Meta:
ordering = ('name', )
views.py
from django.contrib.auth.mixins import LoginRequiredMixin, UserPassesTestMixin
from users.models import Profile
from .models import (character)
class listof_characters(LoginRequiredMixin, ListView):
model = character
template_name = '/list_characters.html'
context_object_name = 'characters'
ordering = ['name']
def get_queryset(self):
?
This is where i'm stuck. I need character.fk_story = User.profile.current_story.
I don't how to phrase this query, I've tried several different things based on other answers and I've tried User.current_story, User.userprofile.current_story as well.
I just need to filter the list of characters by current user's 'current_story' value.

Answer 1

Try to use this:
fk_story = Profile.objects.filter(owner=request.user).order_by('current_story')

Answer 2

Do what Lars said but use self.request.user instead of request.user
UPDATE
urls.py
urlpatterns = [
# other urls
path('characters/<int:pk>/', views.CharactersView.as_view(), name='characters'),
]
views.py
class CharactersView(LoginRequiredMixin, DetailView)
model = story
template_name = '/list_characters.html'
def get_queryset(self):
story = story.objects.get(pk=self.kwargs['pk']) # you need to pass a pk of the story you need the characters for in your url
characters = character.objects.filter(fk_story=story)
return characters
(here i replaced ListView with DetailView so we can query by the story model)
then in your template:
{% for character in characters %}
{{ character.name }}
{% endfor %}
P.S. Always start your Model names and ClassBasedViews with uppercase letters for better readability

Answer 3

def get_queryset(self):
profile = Profile.objects.get(user=self.request.user)
# or better use
# profile = get_object_or_404(Profile, user=self.request.user)
queryset = character.objects.filter(fk_story =profile.current_story)
return queryset
In order for this to work, you also need to change your Profile model.
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
current_story = models.ForeignKey(story, on_delete=models.CASCADE)
return f'{self.user.username} Profile'
Note here I am jusing foreignkey rather than integerfield.
