If I understand you right, you can simply write:  
\<%= link\_to postjob.country, :controller =\> “”, :action =\>  
“country\_list” , :id =\> p %\>  
Is variable p defined? Are you sure it is not “postjob.id”?

I didn’t saw this before.

Why is controller =\> “”?

You have to add the controller name.  
If it is equal to the controller associated to the current  
view’s controller, delete this parameter completely.
