Assign Foreign Key Value After Creating ( Logged In User )

I have a createview using CBV class StudentCreate(LoginRequiredMixin, CreateView): login_url = '/signin/' model = Student fields = ['first_name', 'last_name' ] su

Solution 1:

Look here for the various methods of a CreateView that you can override.

In your case, you want to override the form_valid() method, which is called when the new Student will be saved.

from django.shortcuts import get_object_or_404

defform_valid(self, form):
    self.object = form.save(commit=False)
    self.object.classteacher = get_object_or_404(Class_teacher, email=self.request.user.email)
    self.object.save()
    returnsuper().form_valid(form)

Solution 2:

You need to define your own form_valid(). I assume the Teacher as a one to one Relationship with your User model.

defform_valid(self, form):
    student = form.save(commit=False)
    #retrieve the current logged_in teacher, of course you have to be sure this view is only accesible for teachers (in dispatch for exemple)
    self.object.classteacher = self.request.user.teacher
    self.object.save()
    returnsuper(StudentCreate, self).form_vaild(form)

#bonus the dispatchdefdispatch(self, request, *args, **kwargs):
        #get the loged in userif request.user.teacher:
            returnsuper(StudentCreate, self).dispatch(request, *args, **kwargs)
        else:
            raise Http404
