Hi there,

is it true that with RESTful routes, I can’t pass an additional value to  
the params hash anymore, within a link?

# Example:

## Old school:

\<%= link\_to ‘New message’, :controller =\> ‘messages’, :action =\> ‘new’,  
:target\_id =\> @member.id %\>

## RESTful new school:

\<%= link\_to ‘New message’, new\_user\_message\_path(@user), :target\_id =\>  
@member.id %\>

-\> But doing it like this just ignores the “:taget\_id” that I need to  
pass to the controller !

How should I do this using RESTful routes?

Thanks a lot for your help!  
Tom

this will do

\<%= link\_to ‘New message’, new\_user\_message\_path(@user, :target\_id =\>  
@member.id) %\>

just pass the value within the pathhelper
