MegaProtoUser login

[Ján Raska]

Hi everybody,
I have a small site running on Lift using MegaProtoUser for user management. I included User.menus into my sitemap and everything runs perfectly fine. My page consists of a header containing a logo, narrow left panel with menu and wide right panel for a content. All is done through "default" template using <lift:surround>

All pages require user to be logged in and it works perfectly with Lift, however, the login page is displayed within the "default" template at content panel. I would like the login form to be displayed at the separate page, using different template (let's say "login-tmp"), so that there is just the login form displayed in a centered panel and nothing else, no header, no menu panel, just plain login form. I tried to override MetaMegaProtoUser's loginXhtml method, but it didn't allow me to put there <lift:surround with="login_tmp" at="content">. Is it possible to somehow separate the login form from the "default" template?

Also I'm wondering, is it possible, that user logs in using a nickname (or login name) instead of an email?

Thanks

Rusho

  override protected def loginMenuLocParams: List[LocParam[Unit]] =

Not today, but next week (once issue 684 which is currently on review board) makes it into the codebase.  http://reviewboard.liftweb.net/r/465/

Once 684 makes it into master, you'll be able to do:

 
  /**
   * Given an email address, find the user
   */
  override protected def findUserByEmail(email: String): Box[TheUserType] = find(By(myusernamecolumn, email))

I'm new with lift myself, but I think you may have answered your own
question -- you say "using a different template (let's say "login-
tmp")".
So it seems like you could at the very least copy "default.html" over
to "login-tmp.html" and within "login-tmp.html" take out everything
that
you don't need (titles, footers, etc) and then use that for your
"lift:surround". (Of course you would need a "content" div in there
as the binding point).
I don't think you need to modify loginXhtml to do any of this. In
whatever html file you use to display your initial login page, just
put the
<lift:surround with="login_tmp" at="content"> at the top instead of
"<lift:surround with="default" at="content">
But again, I'm new myself. Hope I've not misunderstood your question.

As for logging in with a login name instead of email -- yes you can do
this.
For my app, I just copied the "def login ..." from the protouser.scala
code and modified to use the "loginid" in my database
instead of the email, like so (this in in my "User.scala" model file)

override def login = {
if (S.post_?) {
S.param("username").
flatMap(username => getSingleton.find(By(loginid, username)))
match {
.....

Thanks David,

overriding loginMenuLocParams managed to display my own login template (though I don't know why it didn't allow me to use S.??("already.logged.in"), complaining that () => LiftResponse is required). However, I might have missed how to specify a login form in such template, because though I do have there a form with action set to "/user_mgt/login" and fields with names such as "username" and "password", the actual login doesn't work and it displays login form again

Thanks David,

Because S ?? "already.logged.in" returns a String.  A String is not a LiftResponse.
 

complaining that () => LiftResponse is required). However, I might have missed how to specify a login form in such template, because though I do have there a form with action set to "/user_mgt/login" and fields with names such as "username" and "password", the actual login doesn't work and it displays login form again

Please post your code in a compilable, runnable (either via Maven or SBT) as a GitHub project and I'll look at it.

Hi David,

I know that S ?? "already.logged.in" returns a String, however, I found in ProtoUser.scala definition:

  /**

   * The LocParams for the menu item for login.

   * Overwrite in order to add custom LocParams. Attention: Not calling super will change the default behavior!

   */

  protected def loginMenuLocParams: List[LocParam[Unit]] =

    If(notLoggedIn_? _, S.??("already.logged.in")) ::

    Template(() => wrapIt(login)) ::

    Nil

That's why I was suprised, that I couldn't us it same way in the overriden method.

I posted my code to GitHub as you asked, I'll be much thankful if you can have a look: git://github.com/rusho/cmstest.git

Thanks

You have to import net.liftweb.sitemap.Loc._ to get the implicit conversion from => String to FailMsg.
