I have a User model. If I do:
def my_action
@user = User.new
end
then
<% form_for(@user) do |f| %>
You can also customize restful routes. For example in my application only the index and show actions are appropriate for certain controllers. In my routes.rb file I have some routes like this:
map.resources :announcements, :only => [:index, :show]
You can also use :except
if that's more appropriate.
