How can I create custom filters in Django Filter?

To create custom filters in Django Filter, you can define a new filter class that inherits from filters.FilterSet. You can then add your custom filter methods.

Can you show me an example of a custom filter?

Sure! Here's a simple example:

import django_filters
from .models import MyModel

class MyModelFilter(django_filters.FilterSet):
    custom_field = django_filters.CharFilter(method='filter_custom_field')

    class Meta:
        model = MyModel
        fields = []

    def filter_custom_field(self, queryset, name, value):
        return queryset.filter(my_field__icontains=value)

What if I want to filter by a date range?

You can use DateFromToRangeFilter from django_filters. Here's how:

from django_filters import DateFromToRangeFilter

class MyModelFilter(django_filters.FilterSet):
    date_range = DateFromToRangeFilter(field_name='date_field')

    class Meta:
        model = MyModel
        fields = []

Is it possible to combine multiple filters?

Yes, you can combine multiple filters in the same FilterSet. Just add them as attributes in your filter class.
