Django - DRF Advanced Features

You wrote this FilterSet but the filtering has no effect:

class UserFilter(FilterSet):
    class Meta:
        model = User
        fields = ['username', 'email']

filter = UserFilter({'user': 'john'}, queryset=User.objects.all())

What is the issue?

AFilterSet must inherit from django_filters.FilterSet

BMissing import of FilterSet

CUsing 'user' instead of 'username' in filter parameters

DQueryset is not passed correctly

Step-by-Step Solution

Solution:

Step 1: Check filter parameter keys
The FilterSet fields are 'username' and 'email', but filter uses 'user' which is invalid.
Step 2: Identify the mismatch
The parameter 'user' does not match any declared field, so django-filter ignores it and returns the unfiltered queryset.
Final Answer:
Using 'user' instead of 'username' in filter parameters -> Option C
Quick Check:
Filter keys must match FilterSet fields [OK]

Quick Trick: Filter keys must match FilterSet fields exactly [OK]
