问题描述

我正在尝试从 Django 1.6 迁移到 Django 1.8 。我正在使用 South 来管理Django 1.6中的迁移。我已经通过 python manage.py makemigrations 成功创建了新的迁移文件。在运行 python manage.py migrate -fake-initial 时，我收到这个错误

I am trying to migrate from Django 1.6 to Django 1.8. I was using South for managing migrations in Django 1.6. I have successfully created new migration files by python manage.py makemigrations. while running python manage.py migrate --fake-initial, I am getting this error

 Traceback (most recent call last):
  File "manage.py", line 39, in <module>

其中一个迁移文件 0001_initial.py 说：

One of the migration file 0001_initial.py says:

dependencies = [
    ('auth', '0006_require_contenttypes_0002'),
    ('clients', '0002_auto_20150428_1551'),
    ('players', '0001_initial'),
]

我猜是特别的问题，什么可以解决这个问题，任何帮助将不胜感激。

which I guess is particularly the problem. What could be the workaround this problem. Any help will be appreciated.

推荐答案

根据 ContentType.name 有关。 com / django / django / commit / b4ac23290772e0c11379eb2dfb81c750b7052b66>这个，但不知何故，它不起作用。

I think this has something to do with "The removal of ContentType.name", according to this. But somehow it doesnt work.

通过手动删除列名称 from'django_content_type'table。例如

By manually removing the column name from 'django_content_type' table. Eg.

'ALTER TABLE django_content_type DROP COLUMN name'

我能够o应用迁移，也许这可以让你有点进一步。

I was able to apply the migrations. Maybe this can get you a little bit further at least.
