Iowa documentation

Does anyone know where I can find some documentation or code examples
for Iowa besides on the http://beta4.com/iowa/ website. The tutorial on
the Iowa website isn’t complete yet, and I was hoping to find some
examples of how sessions work, and how to move between pages. A
complete API reference would be nice too.

The only other documentation I know of is in the book published by
Michael Neumann and co. (Ruby Developer’s Guide, was it?). However,
to answer your immediate questions:

  • the session object can be accessed from any component as @session.
    If you create a subclass of Iowa::Session it will be used instead of
    the standard session class. There’s an example of this in the
    guestbook example, which uses a session subclass to track the number
    of hits.

  • To create a new page, use the pageNamed method, passing it the name
    of a component class. This will return a new instance of that class,
    which you can configure as you want; then yield it to have it be the
    next page shown. Again, there’s an example of this in guestbook/, in
    viewGuest of Main.html.

Cheers,

Not yet. :frowning: I’m working on this. We’ve been moving the last couple of
weeks, though, so I’m way behind on my Iowa work and on other work.
Email me at khaines@enigo.com and I can probably answer your questions.

Avi,

Thanks! I came across the Ruby Developer’s Guide a couple days ago, and
noticed IOWA in the index. I’ve already ordered it, and I’m waiting for
it to arrive. I’ll take a closer look at the guestbook example.
