在Django管理界面中只读模型？ [英] Readonly models in Django admin interface?

问题描述

如何在管理界面中使模型完全只读？这是一种日志表，我使用管理功能进行搜索，排序，过滤等功能，但无需修改日志。

这个例子看起来像一个重复的，这里是不是我想要做的：

• 我不是寻找只读字段（即使使每个字段只读仍然可以让您创建新记录）


• 我不是想创建一个只读用户：每个用户都应该是只读的。

解决方案

只是观看（你不会找到视图权限）。为了达到你想要的目的，你必须禁止添加，删除和使所有字段只读：

  class MyAdmin 
 
 def has_add_permission（self，request，obj = None）：
 return False 
 
 def has_delete_permission（self，request，obj = None）：
 return False 
  

（如果您禁止更改，甚至不会看到对象）

对于一些未经测试的代码，尝试自动设置所有字段为只读请参阅我的答案整个模型为只读

编辑：还未经过测试，但只是看看我的LogEntryAdmin和它有

  readonly_fields = MyModel._meta.get_all_field_names（）
  / pre> 
 
 
不知道是否可以在所有情况下工作。
 
 
 
编辑：QuerySet.delete（ ）可能会批量删除对象。要解决这个问题，请提供您自己的对象管理器和相应的QuerySet子类，不会删除 - 请参阅在Django中覆盖QuerySet.delete（） 
 
How can I make a model completely read-only in the admin interface? It's for a kind of log table, where I'm using the admin features to search, sort, filter etc, but there is no need to modify the log.

In case this looks like a duplicate, here's not what I'm trying to do:


I'm not looking for readonly fields (even making every field readonly would still let you create new records)
I'm not looking to create a readonly user: every user should be readonly.

解决方案
The admin is for editing, not just viewing (you won't find a "view" permission). In order to achieve what you want you'll have to forbid adding, deleting, and make all fields readonly:
class MyAdmin(ModelAdmin):

    def has_add_permission(self, request, obj=None):
        return False

    def has_delete_permission(self, request, obj=None):
        return False
(if you forbid changing you won't even get to see the objects)

For some untested code that tries to automate setting all fields read-only see my answer to Whole model as read-only

EDIT: also untested but just had a look at my LogEntryAdmin and it has
readonly_fields = MyModel._meta.get_all_field_names()
Don't know if that will work in all cases.

EDIT: QuerySet.delete() may still bulk delete objects. To get around this, provide your own "objects" manager and corresponding QuerySet subclass which doesn't delete - see Overriding QuerySet.delete() in Django
