[FIXED] Django - How to access prefetch_related fields?

Issue

students = Student.objects.prefetch_related('user__applications').all()

students.user__applications # Error

So a student has a foreign key to a User object which is associated with a list of applications. But how do I access the list of applications from the Student object?

Solution

Neither prefetch_related nor select_related change the way you access the related data; you do it via the fields or reverse relations, just as you would if you didn't use those methods.

In this case, you have a queryset composed of students; each one of those will have a user attribute, which gives a User object which in turn has an applications field which gives another queryset. So, for example:

students[0].user.applications.all()[0]
