I do not see major pros and cons... it is a matter of precerences...
1) setting username=True in auth.define_tables(), define_tables will add a
field on the table (username) and if that field is present, authentication
will be done using username. Personally I prefer to use emails rather than
usernames, and as I am using BOTH web2py auth and facebook at the same time
for authentication (two different links for different logins), I didn't want
to force my application to use usernames.... so I've used the second option
2) in this case I'm adding an email created by the facebook username +
@facebook and therefore auth will keep using email for authentication...
no web2py code has been touched, although I'm extending Auth and
overriding navbar to display a second login link (facebook) and hide
change_password when it is logged in via facebook.
if session.login_method_used is None:
if not 'change_password' in self.settings.actions_disabled:
bar.insert(-1, ' | ')
bar.insert(-1, password)
and in my controller:
def user():
if auth.user_id:
if request.args[0] == 'logout':
session.login_method_used=None
else:
if request.args[0] == 'login':
session.login_method_used=None
elif request.args[0] == 'login_fb':
session.login_method_used="facebook"
request.args[0]='login'
if session.login_method_used=="facebook":
auth.settings.login_form=FaceBookAccount(globals())
return dict(form=auth())
