Has anyone used Flask-Security extension for authentication? How do I get register view to work?
http://packages.python.org/Flask-Security/customizing.html
I have not really used Flask-Security but the Builderror is referring to the fact that flask cannot bind the security.register view to a URL. security is the name of the blueprint. So may I suggest you try to call the view as follows. Instead of app.route, use security.route.
@security.route('/register', methods=['GET'])
def register():
return render_template('security/register_user.html')
