everyone! I'm using Flask to build a website. But when I open 127.0.0.1:5000, it returns AttributeError: 'Anonymousidentity' object has no attribute 'name'. Anonymousidentity is defined in flask.ext.principal. I have read the flask-principal/init.py where anonymousidentity defined, there is no attribute 'name',neither in class 'Identity'.
I am a beginner and have no idea where the problem is. May someone could help me, any suggestion is also appreciated! :)
Here are the account/service.py . The error occurs in def current_user(identity=None), return models.User.query.get(identity.name)
