我有一个模型，其中布尔字段可见并隐藏在使用admin.py我认为可以在页面上添加默认过滤器/ admin / articles / article /所以它有过滤器by visible = True和hidden = True
class ArticleAdmin(admin.ModelAdmin):
list filter = [...]
...
def changelist_view(self, request, extra_context=None):
if not request.GET: #No filter
#Perform filter to queryset for visible and hidden = True
return super(ArticleAdmin,self).changelist_view(request, extra_context=extra_context)
答案 0 :(得分：0)
