Which of the following is the correct way to define a FilterSet class for a model named Book with a filter on the author field?

Aclass BookFilter(FilterSet):\n class Meta:\n model = Book\n fields = ['author']

Bclass BookFilter(FilterSet):\n model = Book\n fields = ['author']

Cclass BookFilter(FilterSet):\n class Meta:\n fields = ['author']

Dclass BookFilter(FilterSet):\n class Meta:\n model = Book\n filter_fields = ['author']

Step-by-Step Solution

Solution:

Step 1: Recall FilterSet Meta class structure
The Meta class must specify the model and the fields list for filtering.
Step 2: Check each option
class BookFilter(FilterSet):\n class Meta:\n model = Book\n fields = ['author'] correctly defines Meta with model and fields. class BookFilter(FilterSet):\n model = Book\n fields = ['author'] misses Meta class. class BookFilter(FilterSet):\n class Meta:\n fields = ['author'] misses model. class BookFilter(FilterSet):\n class Meta:\n model = Book\n filter_fields = ['author'] uses incorrect attribute 'filter_fields'.
Final Answer:
class BookFilter(FilterSet):\n class Meta:\n model = Book\n fields = ['author'] -> Option A
Quick Check:
FilterSet Meta needs model and fields [OK]

Quick Trick: FilterSet Meta needs model and fields list [OK]
