LoginManager.token_loader removed from flask-login. #17

Open nostneji opened 7 years ago

nostneji commented 7 years ago

When trying to run freshly installed server, several errors will appear:

Traceback (most recent call last): File "__init__.py", line 7, in <module> from flask_login import LoginManager, UserMixin, login_required, login_user, logout_user, current_user, wraps ImportError: cannot import name 'wraps'

and after removing 'wraps' from list

Traceback (most recent call last): File "__init__.py", line 14, in <module> from common_login import * File "/home/jentson/Wrk/omw_env/OMW/omw/common_login.py", line 100, in <module> @login_manager.token_loader AttributeError: 'LoginManager' object has no attribute 'token_loader'

Seems that flask-login has new version which is incompatible with old version (look also https://github.com/maxcountryman/flask-login/blob/master/CHANGES).

Thanks for pointing this out. Any chance you could propose a solution? Currently we are running it on Ubuntu 16.04.2 LTS, which has an older version of flask and thus no problem, which makes it hard for me to debug.

Sorry, but I do not have a ready solution for that problem. I am not familiar with flask and flask-login, too.

But I do know how You can reproduce and debug the problem - You can install virtualenv (https://virtualenv.pypa.io/en/stable/installation/) and create 'a sandbox' for new installation of OMW. In that virtual environment You can install all the latest Python packages with PIP and then make the necessary changes. And there was more dependencies than is written into INSTALL description. In my computer the list of dependencies was following:

$ pip freeze
click==6.7
Flask==0.12
Flask-Login==0.4.0
itsdangerous==0.24
Jinja2==2.9.5
lxml==3.7.3
MarkupSafe==1.0
nltk==3.2.2
requests==2.13.0
six==1.10.0
Werkzeug==0.12.1

Thanks. I think getting it run with a newer flask is a low priority now, but we will definitely keep it in mind (and it is very useful to know more about the dependencies).
