Question

Using Lift, I would like to display a notice to a user after they sign up with something like:

S.notice("Thank you for signing up")

Where would I put this code, or is there another way I should I go about this?

Answer 1

You should be able to put it anywhere in your code to be output on the current page. However, if your code handles the form submission and then redirects to a separate page – you would probably need something like this:

S.redirectTo("/confirm", () => S.notice("Thank you for signing up"))

This will issue the redirect with state. The above executes the function after the redirect – causing the message to be displayed.

In the case of ProtoUser, there are a few places in the API (http://scala-tools.org/mvnsites/liftweb-2.4/#net.liftweb.mapper.MegaProtoUser) that seem like they would work:

 user.toForm("Create User", 
   (u:UserType) => S.notice("Thank you for signing up"))

or you could try calling (or overriding if you want it permanently) this method:

  doPostCommit(() => S.notice("Thank you for signing up")
