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](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?

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.
