解决方法
您可以覆盖ModelAdmin的get_fieldsets方法.
默认实现如下所示：
def get_fieldsets(self,request,obj=None):
"Hook for specifying fieldsets for the add form."
if self.declared_fieldsets:
return self.declared_fieldsets
form = self.get_form(request,obj)
fields = form.base_fields.keys() + list(self.get_readonly_fields(request,obj))
return [(None,{'fields': fields})]
所以你可以覆盖它,例如：
class MyCustomAdmin(ModelAdmin):
def get_fieldsets(self,obj=None):
fs = super(MyCustomAdmin,self).get_fieldsets(request,obj)
# fs now contains [(None,{'fields': fields})],do with it whatever you want
all_fields = fs[0][1]['fields']
return fs
