Question

I’ve got an admin section setup, but am having trouble getting the “update” route to work.

Getting error when hitting “update” via the edit view:
“No action responded to 2.”

For some reason the route is responding to the :id as the :action.

Parameters:
Parameters: {“commit”=>”Update”, “action”=>”2”, “_method”=>”put”, “admin”=>{“ended_at(1i)”=>”2010”, “ended_at(2i)”=>”8”, “ended_at(3i)”=>”22”}, “id”=>”edit”, “controller”=>”admin/subscriptions”}

The edit view uri:
/admin/subscriptions/2/edit

Edit view:

<% form_for :admin, @subscription, :html => {:method => :put} do |f| %>
  <p>
    <%= f.label :ended_at %><br />
    <%= f.date_select :ended_at %>
  </p>
  <p>
    <%= f.submit 'Update' %>
  </p>
<% end %>

Route:

  map.namespace :admin do |admin|
    admin.resources :subscriptions
  end

I assume I need to do something differently in the form_for method or maybe the routes, but everything I’ve tried isn’t working.

Thanks for the help!!

It should be this:

<% form_for [:admin, @subscription] do |f| %>

By putting :admin and @subscription in square-brackets, this makes it into an array which is passed as the first argument to form_for. The benefit of this is if @subscription is a pre-existing record (as-in, one found by find, not created with new) then Rails will know to set the form method to PUT.
