Question

Rails is giving me a route error even though the route appears to
be in the route list.

The form is doing a Post to try to hit the update route on the Admin::ProductsController.
The edit route, index route, and show route work fine.

Using Rails 3.0.5 and ruby 1.9.2

Anyone have an idea? I can’t seem to see the problem.

Error

No route matches “/admin/products/2039”

Code from ERB File that is generating the form

 <%= form_for :product, @product, :url => { :action => "update" } do |f| %>  

Products Controller method at this point is just a stub of

def update
puts params.inspect
end

Routes File

Analytics::Application.routes.draw do

  match 'login' => 'Authentication#login', :via => [:get, :post]    

  namespace :admin do
    # Directs /admin/products/* to Admin::ProductsController
    # (app/controllers/admin/products_controller.rb)
    root :to => 'AdminInterface#index', :via => :get

    resources :products  

    resources :publishers, :only => [:edit, :update]
    match 'publishers/query/:subset' => 'Publishers#index', :as => :publishers_subset, :via => [:get, :post]
  end  
end

Answer 1

According to your routes, shouldn’t that be

= form_for [:admin, @product] do |f|
