小心，self.model._Meta.fields不一定与CustomAdmin具有相同的字段！
“管理员的所有字段”看起来像这样：
from django.contrib import admin
from django.contrib.admin.utils import flatten_fieldsets
class CustomAdmin(admin.ModelAdmin):
def get_readonly_fields(self, request, obj=None):
if request.user.is_superuser:
return self.readonly_fields
if self.declared_fieldsets:
return flatten_fieldsets(self.declared_fieldsets)
else:
return list(set(
[field.name for field in self.opts.local_fields] +
[field.name for field in self.opts.local_many_to_many]
))
