params[:some_data] ||= [] #what does that mean?

While on that question...

Is there any reason I can set up config/routes.rb to had all of the URL
except for the domain, no matter how many slashes or named parameters, to
one 'FigureOutTheUrl' controller?

In that case, how do I deal with a variable number of slashes in the URL?

One step beyond' tressle'.

A wiki with the syntax can be

      /web/topic

No "controller", no "action".
Defaults to "show"
I would think that is what most users might expect.

Only when you need to edit

  /web/topic?edit

Some wiki have a topic that is the index page, like TWiki,
so
  /web/index
is a case of
        /web/topic
and not
  /web action => 'index'
Which means you can write different styles of index pages - not need to hack
the code. isn't that what a wiki is about?

Yes, just make sure it is *the* last url in routes.rb
