Django 管理员 - 更改权限列表 [英] Django admin - change permissions list

问题描述

是否有可能更改用户编辑页面中的权限列表?我不想显示所有权限，例如管理员日志条目或身份验证组等.如何修改主查询集以排除其中的一些?

Is there any possibility to change permissions list in user edit page? I don't wan't to show all of permissions for example admin log entry or auth group etc. How can I modify a main queryset to exclude some of it?

推荐答案

我的想法来自 这个话题，也回答了你的问题，但不是很清楚.

I got the idea from this topic, which also answer your question, but it's not that clear.

您必须覆盖用于可视化的 UserAdmin 表单中的用户权限查询集.

You have to overwrite the queryset of user permissions in the UserAdmin form used for visualization.

为此，最简单的方法是创建 UserAdmin 的子类并覆盖 get_form 方法:

To do this, the easiest way is to create a subclass of UserAdmin and overwrite the get_form method:

from django.contrib.auth.models import User
from django.contrib.auth.admin import UserAdmin

class MyUserAdmin(UserAdmin):
    def get_form(self, request, obj=None, **kwargs):
        # Get form from original UserAdmin.
        form = super(MyUserAdmin, self).get_form(request, obj, **kwargs)
        if 'user_permissions' in form.base_fields:
            permissions = form.base_fields['user_permissions']
            permissions.queryset = permissions.queryset.filter(content_type__name='log entry')
        return form

您可以根据需要更改查询集的过滤器:例子:

You can change the filter of your queryset for whatever you want: Examples:

# Exclude admin and auth.    
permissions.queryset = permissions.queryset.exclude(content_type__app_label__in=['admin', 'auth'])

# Only view permissions of desired models (Can be your models or Django's)
permissions.queryset = permissions.queryset.filter(content_type__model__in=['blog', 'post', 'user', 'group'])

创建类后，您必须向新创建的管理员注册用户模型:

After you create your class, you have to register your User model with your newly created Admin:

admin.site.unregister(User)  # You must unregister first
admin.site.register(User, MyUserAdmin)

我添加了 Maik Hoepfel 的评论，因为这段代码让 django 在创建新用户时崩溃了.

I added comment from Maik Hoepfel, because this code made django crashed when creating new user.

您可以对组编辑页面中的权限列表执行相同的操作，但您必须创建另一个从 GroupAdmin 扩展的管理员，并将 form.base_fields['user_permissions'] 更改为 >form.base_fields['permissions']

You can do the same with the permission list in your Group edit page, but you have to create another Admin that extends from GroupAdmin, and change form.base_fields['user_permissions'] with form.base_fields['permissions']
