hey there,

i have a group\_controller

in there is an action called run\_reports  
in the \_run\_reports.rhml view, i call two partials that are also in the  
group\_controller.  
do those partials have access to the varibles declared in the  
run\_reports action?  
if so, this would save me a lot of repeated code,  
if so, how do i do it ? make them @class variables ?

thanks

See the API documentation for the render() method:

[http://api.rubyonrails.com/classes/ActionController/Base.html#M000206](http://api.rubyonrails.com/classes/ActionController/Base.html#M000206)

Check out the section called “Rendering partials”. You’ll see that you  
can pass variables from the calling scope into the partial as local  
variables in its scope, using the :partials option.

Ciao,

Hi nephish

Partials are just part of a view and you have access in any view to all  
the  
instance variables (e.g., @anything) in the controller action that  
called  
the view.
