迁移与forms.py冲突 [英] Migration clashes with forms.py

问题描述

由于 forms.py ，命令 python manage.py makemigrations 大部分时间失败，其中新增模型或新字段在类定义级别引用。

The command python manage.py makemigrations fails most of time due to the forms.py, in which new models or new fields are referenced at class definition level.

所以我必须评论每个这样的定义以便迁移进行操作。这是一个痛苦的任务。

So I have to comment each such definitions for the migration to operate. It's a painfull task.

我不明白为什么迁移过程导入 forms.py 模块。我认为导入模块模块应该是足够的。

I don't understand why the migration process import the forms.py module. I think that importing models modules should be sufficient.

有没有办法避免这些错误？

Is there a way to avoid those errors ?

推荐答案

感谢@alasdair我明白了我的问题，找到了一个解决方法：我更换了 views.py 文件

Thanks to @alasdair I understood my problem and found a workaround: I replace the original code in the views.py file

from MyApp import forms

与

import sys
if 'makemigrations' not in sys.argv and 'migrate' not in sys.argv:
    from MyApp import forms

在我的情况下工作正常，但我想有一个更好的方式来知道当前进程是否是迁移。如果是这样，请指教。

It works fine in my case, but I suppose there is a better way to know if the current process is a migration or not. If so, please advise.
