I'm still trying to get used to REST concepts and forms

I have a very simple controller that updates user profile data. I have this link that takes me to the controller:

<%= link_to('Profile', :controller => "operator_profile", :action => "edit") %>

I then want to simply display the operator's data like this:

def edit
@operator = Operator.find(current_operator.id)
end

and I want a form that posts to a update method in operator_profile. in my routes I have

resources perator_profile

I feel like I'm completely locked into the 7 base methods of REST and everything else throws routing errors

I couldn't even get the update method to work.

Can this be simplified?
