django 1.7 migrate获取错误“表已存在” [英] django 1.7 migrate gets error "table already exists"

问题描述

django.db.utils.OperationalError：（1050，表'customers_customer'
已经存在）

我通过发出以下命令得到这个：

  python manage.py migrate 
  

我的客户表已经存在，所以我该怎么做让移民知道这一点，而不是出错，并将我的修改运行到我的模型？

我跑了在我的本地环境中与本地数据库没有任何问题。当我指向我的数据库进行生产并运行 migrate 以上时，我收到这个错误。

解决方案

如果您在数据库中创建了表，则可以运行

  python manage.py migrate  - -fake< appname> 
  

将迁移标记为运行而不实际运行

或者如果您想避免迁移中的某些操作，可以编辑app / migrations目录下的迁移文件，并对迁移执行中不想执行的操作进行注释。 / p>

文档： https：/ /docs.djangoproject.com/en/1.8/topics/migrations/#upgrading-from-south
或 python manage.py帮助迁移

I am trying to apply a migration but am getting the error:

django.db.utils.OperationalError: (1050, "Table 'customers_customer' already exists")

I get this by issuing the following command:

python manage.py migrate

My customer table already exists, so what do I do to let the migration know this, not error out, and run my modification to my model?

I ran this on my local environment with local database with no problem. It is when I pointed my database to production and ran migrate above that I get this error.

解决方案

If you have the table created in the database, you can run

python manage.py migrate --fake <appname>

Mark migrations as run without actually running them

Or if you want to avoid some actions in your migration, you can edit the migration file under the app/migrations directory and comment the operations you don't want to do in the migrate execution.
