  • 然后，国家/地区选择的“自动完成”视图将类似于“下一步”

    fromdalimportautocompletefromyour_countries_app.modelsimportCountryclassCountryAutocomplete(autocomplete.Select2QuerySetView):defget_queryset(self):# Don't forget to filter out results depending on the visitor !ifnotself.request.user.is_authenticated():returnCountry.objects.none()qs=Country.objects.all()ifself.q:qs=qs.filter(name__istartswith=self.q)returnqs

• 在url.py中注册视图

  fromyour_countries_app.viewsimportCountryAutocompleteurlpatterns=[url(r'^country-autocomplete/$',CountryAutocomplete.as_view(),name='country-autocomplete',),url(r'^admin/',admin.site.urls),]

• 在admin.py中使用filter

  fromdjango.contribimportadminfromyour_countries_app.modelsimportCountry,Personfromdal_admin_filtersimportAutocompleteFilter@admin.register(Country)classCountryAdmin(admin.ModelAdmin):passclassCountryFilter(AutocompleteFilter):title='Country from'# filter's titlefield_name='from_country'# field name - ForeignKey to Country modelautocomplete_url='country-autocomplete'# url name of Country autocomplete viewclassCountryPlaceholderFilter(AutocompleteFilter):title='Country from'# filter's titlefield_name='from_country'# field name - ForeignKey to Country modelautocomplete_url='country-autocomplete'# url name of Country autocomplete viewis_placeholder_title=True# filter title will be shown as placeholderclassCountryCustomPlaceholderFilter(AutocompleteFilter):title='Country from'# filter's titleparameter_name='from_country'# field name - ForeignKey to Country modelautocomplete_url='country-autocomplete'# url name of Country autocomplete viewwidget_attrs={'data-placeholder':'Filter by country name'}@admin.register(Person)classPersonAdmin(admin.ModelAdmin):classMedia:# Empty media class is required if you are using autocomplete filterpass# If you know better solution for altering admin.media from filter instance#   - please contact me or make a pull requestlist_filter=[CountryFilter]
