[Boulder-Denver Ruby Group] re-inventing components

[David Clements]

Not sure if I am totally following the issue here. I totally agree  
with the premise that the support for widgetizing our apps is really  
ugly. And I use components regularly to widgetize various portions of  
our apps.

Are we talking about syntax or functionality?

We could re-write your example today using render_component_as_string:

class FooController < ApplicationController
   def bar
     # get a handle on, and parameterize, a bar controller
     bar_controller = component_for(:controller => 'bar') do
       @foo = 42
       @bar = 'forty-two'
     end

     # call two actions on the bar controller, potentially reusing  
the entire model+view+controller stack
     foo = bar_controller.content_for :action => 'foo'
     bar = bar_controller.content_for :action => 'bar'

     render :text => [foo, bar].inspect #=> [42, "forty-two"]
   end
end


With this:

class FooController < ApplicationController
   def bar
     params_hash = {:foo => 42, :bar => 'forty_two'}

     # call two actions on the bar controller, potentially reusing  
the entire model+view+controller stack
     foo = render_component_as_string( params_hash.merge(:controller  
=> "bar", :action => "foo" )

     bar = render_component_as_string( params_hash.merge(:controller  
=> "bar", :action => "bar" )

     render :text => [foo, bar].inspect #=> [42, "forty-two"]
   end
end


Not sure if I am missing something,  as I didn't here Bruce's talk  
last week,

Dave

Ara, this stuff looks pretty good.  Like you, I tend to gravitate  
towards OOP,
and it's disappointing that with Rails, MVC is only 1/3 OO.  I'm  
wondering if
it's time to rethink ActionController and ActionView a bit.
