Launch Flask app factory (with create_app()) from external file-CodePudding

Following this tutorial to dockerize a Flask stack, I am trying to lauch an existing application from an external manage.py file

My app structure goes like:

└── services
    └── web
        ├── manage.py
        └── myapp
            └── requirements.txt
            └── myserver
                └──__init__.py

The manage.py file:

import os
os.chdir('myapp')
from flask.cli import FlaskGroup
from myapp.myserver import create_app

app = create_app()

cli = FlaskGroup(app)


if __name__ == "__main__":
    cli()

and finally, the myapp/myserver/__init__.py file (simplified):

from myserver.config.config import Config # this file exists and imports work when i launch from pycharm 

def create_app():
    app = Flask(__name__)
    ...other stuff here
    return app

So when I try to run: python3 manage.py run, the ouput goes:

  File "manage.py", line 4, in <module>
    from myapp.myserver import create_app
  File "/var/www/html/flask-docker/services/web/myapp/myserver/__init__.py", line 12, in <module>
    from myserver.config.config import Config

The config import from __init__.py cannot be resolved. I tried to solve this with the chdir visible in manage.py.

My env variables are the one I got from a working Pycharm flask setup :

FLASK_APP="myserver:create_app()"

I managed to sucessfully pass the import instruction by replacing :

from myserver.config.config import Config

from .config.config import Config

but the whole project contains imports beginning by from myserver

So the final question is: why the init file inside myserver does not recognize myserver folder/module ? This setup works just fine when I laucnh it via PyCharm

CodePudding user response：

Looking at the tutorial, it seems that the config is in myapp/myserver/config.py

So can you try to modify the import

from myserver.config.config import Config

from myserver.config import Config

CodePudding user response：

It can't find the module because it doesn't know what directory to search to find the file manage.py.

try to add manage.py information to init file. from web import manage
