UpdateView using foreignkey in Django

Question

Is there a way that instead of pk i will select the model data by foreign key in UpdateView? It is no doubt it works on the id of the data but what if i will select the data object in the model using foreign key condition? How would i do that?

Here is my UpdateView class:

class SettingsProfileView(UpdateView):
    model               = UserInfoModel
    template_name       = 'site/views/settingsprofile.html'
    form_class          = UserInfoForm

I try to put:

def getquery_set(self):
   return self.model.objects.filter(users_id = self.kwargs['pk'])

but still its refering to get the data by primary key.

Answer 1

The method is .get_queryset(..) [Django-doc] not getquery_set, but nevertheless, this will not work, since the filtering is done in the .get_object(..) method [Django-doc].

You thus can work with:

from django.shortcuts import get_object_or_404

class SettingsProfileView(UpdateView):
    model = UserInfoModel
    template_name = 'site/views/settingsprofile.html'
    form_class = UserInfoForm

    def get_object(self, queryset=None):
        if queryset is None:
            queryset = self.get_queryset()
        return get_object_or_404(queryset, user_id=self.kwargs['pk'])
