from django . contrib import admin
from django . db . models import Q , Field , TextField
from admin_site_search . views import AdminSiteSearchView

"""Extends super() to add TextField support to site search"""
if isinstance ( field , TextField ):
return Q ( ** { f" { field . name } __icontains" : query })
return super (). filter_field ( query , field )
Beachten Sie, dass dies aus Leistungsgründen nicht standardmäßig erfolgt: __icontains
ist bei einer großen Anzahl von Texteinträgen nicht optimal.
