Django Python:为特定用户添加自定义权限 [英] Django Python : adding custom permissions to specific users

问题描述

Models.py

  class Meta:权限=(("can_add_data"，可以添加新数据")，) 

这是我在Models.py中创建的自定义权限，并且我还创建了这些用户.

然后，找到所需的权限( ref-1 )(在您的情况下， app_name | model_name |可以添加新数据)，然后单击( ref-2 和 ref-3 )，然后保存

注意:权限分配过程是一次性的，因此您不必每次都进行更新，除非您需要更改/重新分配权限.

如何在API中使用此权限
在您的 views.py 中，定义一个这样的视图，

来自django.contrib.auth.decorators的

 导入Permission_required@permission_required('app_name.can_add_data')def my_view(要求):# 做一点事返回HttpResponse("response") 

Models.py

class Meta:
    permissions = (
        ("can_add_data","can add a new data"),
        )

This is the custom permission I've created in Models.py and I've also created these users.

Users in Django Admin ie., http://localhost:8000/admin

How do I give permission to specific users so that I can use @permission_required('myapp.can_add_data') in views.py and also where do I write the snippet? (in which file)

I'm a beginner at this so if there are any mistakes please let me know.

解决方案

You can assign permission to user through either Django Admin or Django shell
through django-shell
open your django shell by python manage.py shell and run the following statements

In [1] from django.contrib.auth.models import Permission,User
In [2] permission = Permission.objects.get(name='can add a new data')
In [3] user = User.objects.get(id=user_id)
In [4] user.user_permissions.add(permission)

through django-admin
open your django-admin page and head to Users section and select your desired user.
There you can see User permissions section as in below image,



Then, find your desired permission (ref-1) (in your case app_name|model_name|can add a new data) and click (ref-2 and ref-3), then save

NOTE: Permission assigning process is a one-time thing, so you dont have to update it every time unless you need to change/re-assign the permissions.

How to use this permission in API
in you views.py, define a view like this,

from django.contrib.auth.decorators import permission_required


@permission_required('app_name.can_add_data')
def my_view(request):
    # do something
    return HttpResponse("response")
