Djangoで親のfilter_horizo​​ntalに追加admin

Question

ModelAdmin.get_fields()と同様に、サブクラスに項目を追加できるような他のヘルパー関数もありますが、これはfilter_horizo​​ntalに対して可能ですか？現時点では私は、それぞれの子adminクラスに手動で再書き込みリストにあります

BaseAdminClass(admin.ModelAdmin): 
    ... 
    fields = ['some_field', 'many_to_many_field'] 
    filter_horizontal = ['many_to_many_field'] 


ChildAdminClassOne(admin.ModelAdmin): 
    def get_fields(self, request, obj=None): 
     fields = super(ChildAdminClass, self).get_fields(request, obj) 
     return fields + ['another_field'] 

    # Something like get_filter_horizontal()? 
    filter_horizontal = ['many_to_many_field' + 'another_field'] 


ChildAdminClassTwo(admin.ModelAdmin): 
    def get_fields(self, request, obj=None): 
     fields = super(ChildAdminClass, self).get_fields(request, obj) 
     return fields + ['other_field'] 

    filter_horizontal = ['many_to_many_field' + 'other_field'] 

Answer 1

あなたも、より便利fieldsよりもそれを行うことができます。クラス属性をプロパティで上書きするだけです。私はちょうど私が単に各サブクラスでこれを行うことができます実現

class BaseAdminClass(admin.ModelAdmin): 
    fields = ['some_field', 'many_to_many_field'] 
    default_filter_horizontal = ['many_to_many_field'] 
    additional_filter_horizontal = [] 

    @property 
    def filter_horizontal(self): 
     return self.default_filter_horizontal + self.additional_filter_horizontal 

class ChildAdminClass(BaseAdminClass): 
    fields = ['some_field', 'many_to_many_field'] 
    additional_filter_horizontal = ['other_field'] 

Answer 2

：

BaseAdminClass(admin.ModelAdmin): 
    fields = ['some_field', 'many_to_many_field'] 
    filter_horizontal = ['many_to_many_field'] 

ChildAdminClassOne(admin.ModelAdmin): 
def get_fields(self, request, obj=None): 
     fields = super(ChildAdminClass, self).get_fields(request, obj) 
     return fields + ['another_field'] 

    # Something like get_filter_horizontal()? 
    filter_horizontal = BaseAdminClass.filter_horizontal + ['another_field']
