R helper only looks at the number of arguments

[mdaines]

I'm not sure if this is going to be found much in the wild, but it seems useful to have the R helper also see if the url it choses matches what's generated. If you had a controller like this:

class Number < R '/name/([a-z]+)', '/number/(\d+)'
  def get(n)
    @number = n
    render :number
  end
end

And you ask for, say, R(:Number, 2), you'll always get /name/2 instead of /number/2.

Let's see if we can wheedle it down a bit tinier.

Replying to why:

I will take a look! A little while after I posted this I just completely forgot about it.

As a point of interest I was also working on something slightly related -- Rails-style "REST" resource controllers. In one or two Camping apps I have started I have done stuff like this:

module Controllers

  class ReportsCollection < R '/reports'
    # ...
  end

  class NewReportsMember < R '/reports/new'
    # ...
  end

  class ReportsMember < R '/reports/(\d+)'
    # ...
  end
  
end

Instead I would like this:

module Controllers

  class Reports < ZZZ
    # ...
  end
  
end

Maybe that is too much magic though.

How's this? (And by the way, attachments don't seem to be working)

Thanks, I used you patch as an inspiration for change set [236].
