I have this models and the view for user profile.

def userprofile(request, pk):
user = User.objects.get(username=pk)
#groups = user.room_set.all()
groups = Room.objects.filter(admin=user)
all_groups = Room.objects.filter(members=user)
return render(request, 'base/profile.html', {'user':user, 'groups':groups, 'all_groups':all_groups})
Please explain how _set.all method filter method are doing the same job.
I don't understand where the room is coming from (there is only (Room) model.
explain the mechanism of user.room_set.all line respect to filter;

Im Try to Catch any data from database with table name is 'UserUsulan'.
I have two field, 'Ketua' and 'Anggota'.
In Ketua Field is ForeignKey from User, and Anggota is ManyToMany Field with relationship from User.
I want to render the data.
if in Ketua Field equal current.user render the data.
and also if current.user in Anggota field i want it render too.
So,
If the current.user is not able in Ketua Field, but able in Anggota Field. Render the Data
If the current.user is not able in Anggota Field, buat able in Ketua Field. Render the Data Too.
How To Solve this problem.
Im read with this documentation Spanning multi-valued relationships . But the Queryset is empty[].

queryset = super(UserUsulanPenelitianCreateAndListView, self).get_queryset()
queryset = queryset.filter(ketua=self.request.user,).filter(anggota=self.request.user,)
print(queryset)
return queryset
I Found The Answer, Using Q for the queryset
Import Q
from django.db.models import Q
Using Q in Queryset
def get_queryset(self):
queryset = super(UserUsulanPenelitianCreateAndListView, self).get_queryset()
queryset = queryset.filter(Q(ketua=self.request.user)|Q(anggota=self.request.user)).distinct()
print(queryset)
return queryset
Following this link and documentation, somehow it still can't save an Object with 2 Foreinkeys.
