What I do in this case is add the related object into the context data. It would be something like this:
class UserProfileDetailView(DetailView):
model = get_user_model()
slug_field = "username"
template_name = "perfil.html"
def get_context_data(self, **kwargs):
# xxx will be available in the template as the related objects
context = super(UserProfileDetailView, self).get_context_data(**kwargs)
context['xxx'] = AnotherModel.objects.filter(var=self.get_object())
return context

Another approach is to extend DetailView
with MultipleObjectMixin
, as in this example:
from django.views.generic import DetailView
from django.views.generic.list import MultipleObjectMixin
from django.contrib.auth import get_user_model
class DetailListView(MultipleObjectMixin, DetailView):
related_model_name = None
def get_queryset(self):
# a bit of safety checks
if not hasattr(self, "related_model_name"):
raise AttributeError(
"%s.related_model_name is missing." % (
self.__class__.__name,))
if not self.related_object_name:
raise NotImplementedError(
"%s.related_model_name must not be None." % (
self.__class__.__name,))
# get the object
obj = self.get_object()
# get the related model attached to the object
related_model = getattr(obj, "%s_set" % self.related_model_name, None)
# safety check if related model doesn't exist
if not related_model:
raise AttributeError(
"%s instance has no attribute \"%s_set\"" % (
obj.__class__.__name__, self.related_model_name)
# return the related model queryset
return related_model.all()
def get(self, request, *args, **kwargs):
self.object_list = self.get_queryset()
return super(DetailListView, self).get(request, *args, **kwargs)
class UserProfileDetailView(DetailListView):
template_name = "perfil.html"
model = get_user_model()
slug_field = "username"
related_model_name = "anothermodel"
def get_object(self, queryset=None):
user = super(UserProfileDetailView, self).get_object(queryset)
UserProfile.objects.get_or_create(user=user)
return user
In my opinion this approach is a little less cleaner and understandable, but it has a huge advantage in reusability. It definitely has one downside: if you are using the class variable context_object_name
, it will refer to the related objects list and not to the object itself (this has to do with how the inheritance chain is set up when constructing the class).
