Add "Remember Me?" checkbox for extended sessions?

[Kenneth McDonald]

Following the instructions on Assembla, I've successfully added Extended Session (remember me on this computer) functionality to my project. However, the instructions I was following didn't give any way of adding a "Remember me on this computer" checkbox to the login screen. Before I go in and try to add this myself, I was wondering if code had already been written to do this.

Thanks,

Ken

It'd be great if you could share what you find: I'll need to do this before May 2012 for UK legislation changes regarding how cookies are used. 

Or: I'm happy to help out if you need any assistance.

The instructions for Extended Session on Assembla was GREAT! It was
such an easy thing to add. Thanks!

Regarding your question;

I don't think there is such a thing ready-made, but it would be rather
simple to do. Instead of just doing:

onLogIn = List(MyExtendedSession.userDidLogin _)
onLogOut = List(MyExtendedSession.userDidLogout _)

in your User Meta, you would probably want to add the checkbox to your
login-form and then only call MyExtendedSession.userDidLogin if it was
checked.

You could of course trait-ify this with a self-type of ProtoUser that:

* adds a boolean field on the model (doesn't need to be mapped, right?)
* overrides def loginXhtml to include the checkbox and save it to the model
* puts a hook in onLogIn: List[TheUserType => Unit] to call
MyExtendedSession.userDidLogin _ if the field was set

but it feels rather crappy to add an extra field on the user model
just for this since it shouldn't really be part of the model, but
should have a life time just tied to the login-form. I don't see any
other simple way though since the hooks are defined on the model.

Hm, I think I would just make my a custom login-page instead.

Cheers,

Could you open a ticket on this feature referencing this thread.  I'll see what I can do to get it into Lift so it'll be easier to comply with UK laws.

Thanks David: http://www.assembla.com/spaces/liftweb/tickets/1103

I'd assumed it'd be a bit of hacking on the web app itself, but if there's something you can do in Lift to make it easy, that'd be wonderful. Thank you.

Ken - you might want to check that ticket to make sure we're both taking about the same thing.

Yes, that's exactly what I was talking about. Thanks, David, for looking into adding this.
