django：数据迁移权限 [英] django: data migrate permissions

问题描述

我有一堆我需要迁移的新权限。我尝试通过数据迁移进行，但抱怨 ContentType不可用。

快速研究我发现

我甚至尝试使用 update_all_contenttypes（ ）从django.contrib.contenttypes.management导入update_all_contenttypes
的导致迁移加载与固定装置不一致的数据。

在Django中迁移权限数据的最佳方式是什么？

解决方案

p>有两种解决方法：

1）丑陋的方式：

运行 manage.py migration auth 在您想要的迁移之前

2）推荐方法：

  from django.contrib.auth.management import create_permissions 
 
 def add_permissions（apps，schema_editor）：
 apps.models_module = True 
 
 create_permissions（apps，verbosity = 0）
 apps.models_module =无
 
＃其余的代码在这里.... 
  

I have a bunch of new permissions which I need to migrate. I tried doing it through data migration but complains about ContentType not being available.

Doing quick research I found out that ContentType table is populated after all the migrations applied.

I even tried using update_all_contenttypes() from from django.contrib.contenttypes.management import update_all_contenttypes which causes migration to load data which is not consistent to the fixture.

What is the best way to migrate permission data in Django?

解决方案

There are 2 ways to solve this:

1) The ugly way:

Run manage.py migrate auth before your wanted migration

2) Recommended way:

from django.contrib.auth.management import create_permissions

def add_permissions(apps, schema_editor):
    apps.models_module = True

    create_permissions(apps, verbosity=0)
    apps.models_module = None

    # rest of code here....
