If I am in controller A and I want to show the index of controller B,  
how would I do that?

Wouldn’t you just do a simple redirect?

def create  
@scenario = Scenario.new(params[:scenario])  
if @scenario.save  
flash[:notice] = ‘Scenario was successfully created.’  
# where do we return to?  
case params[:from\_type]  
when ‘project’  
redirect\_to projectview\_path(params[:from\_id])  
else  
redirect\_to scenarioviews\_path  
end  
else  
render :action =\> “new”  
end  
end

No, I dont want to redirect to another controller. I want to stay in my  
current controller.

Here is what I did:

from my controller A I ran an RJS file.  
The RJS file replaces my content area with a partial.  
My partial uses one line of code

\<%= render\_file “CONTROLLER\_B\_NAME/index.html.erb” %\>

If anybody else knows a better why, I’d be appreciative to hear it.

In controller A:

render :controller\_b, :action =\> “your\_action”

I believe it’s:

render(:controller =\> “controller\_name”, :action =\> “your\_action”)

I haven’t tried it, but that’s the syntax for redirect\_to

HTH.
