Django admin - 使所有字段只读
问题描述
我正在尝试将所有字段设为只读而不明确列出它们.
I'm trying to make all fields readonly without listing them explicitly.
类似:
class CustomAdmin(admin.ModelAdmin):
def get_readonly_fields(self, request, obj=None):
if request.user.is_superuser:
return self.readonly_fields
return self.fields
问题是CustomAdmin.fields此时没有设置.
有什么想法吗?
解决方案
注意，self.model._meta.fields 不一定是 CustomAdmin 的同一个字段！
Careful, self.model._meta.fields are not necessarily the same fields that CustomAdmin has!
Admin 的所有字段"看起来更像这样:
"All fields of the Admin" would look more like this:
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]
))
