Registration e-mail verification

I want to implement a mechanism where someone can register for an
account on a Seaside web site by providing an e-mail address.  In order
for the registration to be completed, Seaside will send them an e-mail
containing a link which they have to click on to return to the web site
to continue the registration process.

Sending the e-mail isn't a problem.  How can I generate the URL in
advance to put into the e-mail that the user can click on to complete
the registration process?

Thanks
David Buck

Dave,

It sounds like you're thinking about generating a URL to a callback that
will activate an account, but a safer thing to do would be to disconnect
the email from your session by doing something like,

1. On account store unique activation key
2. On your root component implement

initialRequest: aRequest
 super initialRequest: aRequest.
 aRequest
  at: 'activate'
  ifPresent: [:acc |
      aRequest
       at: 'with'
       ifPresent: [:key | "activate acc with key"].

3. Then email URLs of form,

http://www.myapp.com/online?activate=1234&with=567890

Hope this helps,

-Boris

Extracted from code used in industry:

        | account |
        account := self collectAccountInformation.
        Continuation currentDo: [ :cc |
                self sendOutMailWithUrl: (self session actionUrlForContinuation: cc)
                ^ self displayInstructionToCheckMail: account ].
        self displayConfirmation: account activate

Cute.

Does this work if the session expires (e.g. if the user does not have
his e-mail handy because of firewalls, and didn't expect having to check
his e-mail)?

No, the URL is invalid after the session expires. One thing what you
could do, is to temporarily increase the session timeout to a couple
of days, while waiting for the confirmation.

Cheers,
