I have two rails application.  
On clicking a link on Application 1’s index.html.rb page I wish to do  
some processing like retreiving info about the selected record from DB.  
and then make a call to a different rails application.  
Do I need to write code in my view using helper functions or I can do  
this in controller.  
I wish to do this in controller… as it will mean a cleaner code in  
view.  
Is there some dispatch mechanism available in Rails controller.

What exactly does “make a call to a different rails application” mean?

For example  
I wish to call [www.google.com](http://www.google.com) with some parameters from my rails  
application then what should I do.  
I am firing some soap requests to get those input parameters for google.  
Hence I need to write some code in my controller.  
Something like I am calling show function of scaffold generated project  
and there I am calling [google.com](http://google.com) iso default show.html created by  
scaffold

Then you can use ‘net/http’ to send a regular http request, like so:

require ‘net/http’

connection = Net::HTTP.new(“[www.google.com](http://www.google.com)”)  
response = “”  
connection.start do |http|  
req =  
Net::HTTP::Get.new(“/#hl=en&source=hp&q=ruby+on+rails&fp=c26c79a56c95bda8”)  
response = http.request(req)  
end  
#do something with response

This can of course be put in the controller, but also the model if that  
suits you better.

I see. Can’t you just put :popup =\> true on the link in the view, and  
then use a redirect\_to in the controller?

Basically I wish to open the 2nd page by specifying its url and  
parameters in a different window by clicking a link in first application  
this link will call the controller function where soap requests will be  
sent to server and based on that reponse I open a new website with  
parameters.
