# Django Admin Search

Haystack comes with a base class to support searching via Haystack in the Django admin. To use Haystack to search, inherit from `haystack.admin.SearchModelAdmin` instead of `django.contrib.admin.ModelAdmin`.

For example:

    from haystack.admin import SearchModelAdmin
    from .models import MockModel

    class MockModelAdmin(SearchModelAdmin):
        haystack_connection = 'solr'
        date_hierarchy = 'pub_date'
        list_display = ('author', 'pub_date')

    admin.site.register(MockModel, MockModelAdmin)

You can also specify the Haystack connection used by the search with the `haystack_connection` property on the model admin class. If not specified, the default connection will be used.

If you already have a base model admin class you use, there is also a mixin you can use instead:

    from django.contrib import admin
    from haystack.admin import SearchModelAdminMixin
    from .models import MockModel

    class MyCustomModelAdmin(admin.ModelAdmin):
        pass

    class MockModelAdmin(SearchModelAdminMixin, MyCustomModelAdmin):
        haystack_connection = 'solr'
        date_hierarchy = 'pub_date'
        list_display = ('author', 'pub_date')

    admin.site.register(MockModel, MockModelAdmin)
