migrate and upgrade error about aerich

[long2ice]

是执行哪一步的时候出错了？

是执行哪一步的时候出错了？

就是执行迁移的时候出错了, 迁移的时候产生的路径是migrations\models\old_models这样的, 乌龟没有识别, 他要识别migrations.models.old_models这样的, 上面我提到的修改乌龟的init文件355行可以解决目前的问题,我的乌龟版本是tortoise 0.1.1,

[long2ice]

是aerich的版本吧？你升级最新的0.2.0试试

是aerich的版本吧？你升级最新的0.2.0试试

好的, 我目前的是0.1.9, 由于替换了源装不上0.2.0, 我把源改回去试试

[long2ice]

从最新的dev分支安装

[mosheduminer]

I cannot upgrade with either aerich 0.2.0 nor the latest dev branch. With 0.2.0 the error is

ModuleNotFoundError: No module named 'migrations\\models\\old_models'

On the latest dev, the error is

ModuleNotFoundError: No module named '/migrations'

Can you please help/advise?

I'm using windows 10, python 3.8.

@mosheduminer Can I see your aerich.ini?

[mosheduminer]

@long2ice my aerich.ini file is as follows:

[aerich]
tortoise_orm = app.settings.TORTOISE_ORM
location = ./migrations

Sorry I can't point you towards a repo, the code is private.

[long2ice]

Since you use windows，your location maybe .\migrations

[mosheduminer]

@long2ice that fixed it! Thanks! Only now I have another issue, my models are defined in multiple files, with relative imports between them. Would it be correct to say that aerich cannot handle relative imports?

[long2ice]

You can give a try.

[mosheduminer]

Ah, I was asking because I get the following error:

ModuleNotFoundError: No module named 'migrations.models.user'

Which appears to happen due to a relative import...

It seems that all the models are put in a single old_models file, without the imports being removed. For example, this is taken from the __init__.py file:

from .user import User
from .building import Building
from .apartment import Apartment
from .package import Package

with further imports between files. I changed the imports to be absolute, and everything works now. Thanks you so much for your help!

[long2ice]

You are welcome.

@long2ice Hello, regarding Module "\migrations\models\old_models" not found, I used your method above and still failed to solve my problem. Is there any other way to deal with it?
