How to Refactor Module using python rope?

Question

I have my project structure as following

├── app
│   ├── Country
│   │   └── views.py
│   ├── Customer
│   │   └── views.py

Where the module 'Country' folder is what I tried to rename it to 'Countries' and every occurrence it is used, and it is also imported in Customer/views.py as well.

from app.Country.views   import *
....

According to this tutorial Refactoring Python Applications for Simplicity, I tried it as below:

>>> from rope.base.project import Project
>>> 
>>> proj = Project('app')
>>> 
>>> Country = proj.get_folder('Country')
>>> 
>>> from rope.refactor.rename import Rename
>>> 
>>> change = Rename(proj, Country).get_changes('Countries')
>>> proj.do(change)

After executing the script, the module folder 'Country' was changed to 'Countries' but its instance where it is used in Customer/views.py does not change accordingly, the import statement in Customer/views.py is still

from app.Country.views   import *

I expected it should change to from app.Countries.views import * after refactoring, but it did not.

Is there anything else I should do to refactor this successfully? Thanks.

You could use proj.get_module('app.Country').get_resource() to rename module.

from rope.base.project import Project
from rope.refactor.rename import Rename

proj = Project('app')
country = proj.get_module('app.Country').get_resource()
change = Rename(proj, country).get_changes('Countries')
print(change.get_description())
