drf-haystack-search-filter

A simple package to implement a django-haystack search filter in Django Rest Framework.

Installation

pip install drf-haystack-search-filter

Usage

Simply import the HaystackSearchFilter and use it in your API views:

from drf_haystack_search_filter.filters import HaystackSearchFilter

...

class MyAPIView(...):
    ...
    filter_backends = [HaystackSearchFilter, ...]
    ...

You can customize the search behavior by overriding the _search method.

from typing import TypeVar

from drf_haystack_search_filter import HaystackSearchFilter

T = TypeVar("T")


class MyHaystackSearchFilter(HaystackSearchFilter):
    def _search(self, request: Request, queryset: QuerySet[T], view: APIView, query: str) -> QuerySet[T]:
        # Customize the search behavior here
        return queryset.filter(
            pk__in=(
                SearchQuerySet()
                .models(queryset.model)
                .filter(content__startswith=query)
                .values_list("pk", flat=True)
            )
        )

class MyAPIView(...):
    ...
    filter_backends = [MyHaystackSearchFilter, ...]
    ...
