Immutable tuple URL sqlachemy

[DeclercqM]

In the following commit has sqlalchemy decided to make it a tuple.

When executing flask db migration is this the result.

This is a Flask-SQLAlchemy error, it does not appear to be related to this package. Does your application work? If you think it is this package, then please provide an example application that I can use to reproduce the error.

[DeclercqM]

My apologies for posting this issue on the wrong package. On this link you can find an example application to re produce the error. After installing the venv and the setup.py the next command to reproduce the error is flask db init and flask migrate -m "message migration"

@DeclercqM Going back to my question, I asked if the application runs fine. I installed your repo and can't do flask run, I get weird errors. Your __init__.py file has an from app import routes yet there is no app package. There is nothing here that points to errors in this package, I think you need to review your basic application structure and make sure all the pieces are working well together.

@DeclercqM I was getting the same error, I fixed it by changing SQLAlchemy version to 1.3.18.
