Merb Slice and Resources, wrong number of arguments

merb : worker (port 4000) ~ Started request handling: Mon Feb 23 01:08:49 +0100 2009
merb : worker (port 4000) ~ Routed to: {"format"=>nil, "submit"=>"Create Page", "action"=>"create", "controller"=>"webbastic/pages", "page"=>{"name"=>"home", "site_id"=>"1"}}
merb : worker (port 4000) ~ Params: {"format"=>nil, "submit"=>"Create Page", "action"=>"create", "controller"=>"webbastic/pages", "page"=>{"name"=>"home", "site_id"=>"1"}}
merb : worker (port 4000) ~ wrong number of arguments (0 for 1) - (ArgumentError)

When using resources in a Merb Slice, you can get this kind of error.
I still don’t know the core of the problem, but I’ve found how to solve it.

It begins with the signature of the resource contoller method:

  # POST /pages
  def create(page)
    @page = Webbastic::Page.new(page)
	.....

Someway, the page object doesn’t pass through – number of argument equals 0 – but you can still access to your parameters with params object, modifying the method this way:

  # POST /pages
  def create
    @page = Webbastic::Page.new(params[:page])
	.....

I’ve post a ticket on Merb dashboard, so this might have another official solution soon: ticket #1225
