routes.rb

map.connect ‘:controller/:action/:id/:draw\_id’, :controller =\>  
“admin”, :action =\> “edit\_position”

In a view I have:

\<%= link\_to “#{@draw.positions[0].team}”, { :controller  
=\> :admin, :action =\> :edit\_position,  
:id  
=\>@draw.positions[0].id, :draw\_id =\> @draw.id } %\>

In my controller I do not receive the param :draw\_id in my params[]

Any thoughts? How do I do a link\_to and pass in these 2  
parameters :id and :draw\_id

Thanks!

Shawn

the param :draw\_id would be sent as a parameter…

[http://www.example.com/controller/action/id?draw\_id=1](http://www.example.com/controller/action/id?draw_id=1)

thus, there really is no need to represent it in routes.rb

It is not in my params hash though…

I initially did nothing with my routes.rb… then seeing that the only  
param I got was :id, I started playing around.

can anyone give me an example of a link\_to that sends 2 parameters to  
a controller.

This seems so silly, but I am stuck.

Thanks so much…

link\_to “link”, :controller =\> “articles”, :id =\> id, :draw\_id =\>  
@draw.id

Sure… but how would you access the :draw\_id in your controller?

It is not showing up in my params hash… with what you wrote I only  
get :id in the hash as well as action and controller.

Is draw\_id showing in the log file (log/development.log). If not then  
@draw.id is probably nil. Have a look at the html of your page (View,  
Page source or similar in your browser) and see if it is there. Also  
you could try displaying @draw.id in the page to see what it is.

By the way most think it better to insert your comments to previous  
emails inline rather than at the top. It makes it easier to follow  
the thread.
