您可以创建一个自定义SimpleListFilter来在您的管理上生成动态过滤器。在SimpleListFilter中，如果lookups方法返回一个空的元组/列表，则过滤器被禁用（也从视图中隐藏）。这可用于控制某些过滤器何时出现。
这里有一个基本的过滤器：

class CountryFilter(admin.SimpleListFilter):

    title = 'Country'
    parameter_name = 'country'

    def lookups(self, request, model_admin):
        """ Return a list of (country_id, country_name) tuples """
        countries = Country.objects.all()
        return [(c.id, c.name) for c in countries]

    def queryset(self, request, queryset):
        ...

下面是一个过滤器，其中选项基于上面的过滤器受到限制：

class StateFilter(admin.SimpleListFilter):

     title = 'State'
     parameter_name = 'state'

     def lookups(self, request, model_admin):
         """ 
         Return a list of (state_id, state_name) tuples based on 
         country selected 
         """

         # retrieve the current country the user has selected
         country_id = request.GET.get('country')
         if country_id is None:
             # state filter will be hidden
             return []

         # only return states which belong in the country
         states = State.objects.filter(country_id=country_id)
         return [(s.id, s.name) for s in states]

     def queryset(self, request, queryset):
         ...

一般的想法是在过滤器类上使用lookups来限制后续过滤器上的选项。这些过滤器可以通过list_filter参数应用于管理员。

class MyAdmin(admin.ModelAdmin):

     list_filter = [CountryFilter, StateFilter, CityFilter, ...]
