link_to and routing question

rubyonrails-talk
1

I have the following link_to:

<%= link_to("Remove", {:action => "remove_role_from_account", :role_id => role, :account_id => @account}) %>

It generates: http://myserver.com/roles/remove_role_from_account?account_id=1&role_id=5

But this doesn't match the right default route:

{:action=>"wsdl"} /:controller/:action/:id.:format               /:controller/:action/:id

So it's not hitting my action "remove_role_from_account" and instead is try to go to action "show" with the id as "remove_role_from_account"

what am i doing wrong here?

In all my humble newbieness, it looks to me like, when you get a URL of the form /roles/something?with_this?and_that, the first pattern that the route table finds that matches that is the pattern that looks like: /roles/:id, so you get routed to the “show” action of the "roles"controller. I know that the routes table is processed in order and the first pattern that matches is the one that triggers the action (which is why the /:controller/:action/:id pattern is always listed last.).

What I don’t know is, why does {:action => “remove_role_from_account”, :role_id => role, :account_id => @account} produce a url of the form: /roles/remove_role_from_account, when you specifically plug in an action of “remove_role_from_account”.

Sorry if this doesn’t help much.
