Rails 'render' question

Is it possible to render a template for an action not within the current controller?

e.g.,

Code:

render :controller => 'different', :action => 'index'

If there is both controller_name.rhtml and application.rhtml within the layouts directory, can I specify which layout to use (or alternatively render them within eachother)?

You can access any actionview using

Code:

render :template => 'different/action', :layout => 'mylayout'

The layout is optional. Normally the current layout is used.

Usually you create a partial view, when you want to reuse some of your code in different actions. It is a much cleaner approach.

Code:

# render $RAILSROOT/app/views/lib/_adminheader.rhtml
# using layout 'layouts/thelayout.rhtml'
# through :locals we provide the variables used in the partial
render :partial => 'lib/adminheader',
       :locals => { :page => @page, :somevar => @variable },
       :layout => 'thelayout'

Take a look here for further documentation.

OK, one more question:

If I call

Code:

render :template => 'different/action'

This will not execute the controller code for the called action, but will only render the view of that action (using locals, etc. from the currently executing action).

OTOH, if I call

Code:

render_component :controller=> 'different', :action => 'action', :params => params

This both executes the controller action for 'different/action' and renders the view of that action (using locals, etc. from the 'different/action' action.)

Is that correct?
