ruby - How to insert data in product table with user id rails 4 -

hello absolute newbie in rails. creating application stuck on point.

the problem want insert data in products per user id saying:

uninitialized constant productcontroller

here route file:

rails.application.routes.draw   #devise_for :users   devise_for :users, :controllers => { :registrations => 'users/registrations' }   resources :dashboard   root to: "home#index"    namespace :user     resources :users   end    resources :product end 

here product controller i.e, product_controller.rb:

class product::productcontroller < applicationcontroller   def new     @product = product.new   end    def create     @product = product.new(params[:product])     if @product.save       flash[:success] = "product added"       redirect_to product_index_path     else       flash[:success] = @product.errors.full_messages.join       redirect_to :back     end     end   end 

and here new.html.erb code:

<h2>add product</h2>  <%= form_for(resource, :as => resource_name, :url => user_registration_path) |f| %>    <div class="field">     <%= f.label :product_name %><br />     <%= f.text_field :product_name, autofocus: true %>   </div>  <%= p.hidden_field :user_id, :value => current_user %>    <div class="actions">     <%= f.submit "add product" %>   </div> <% end %>  <% end %> 

i know thing wrong too:

<%= form_for(resource, :as => resource_name, :url => user_registration_path) |f| %> 

how can make parts one? goal take use new page add product name , redirect product list page.

rename controller products_controller.rb

then change

class product::productcontroller < applicationcontroller   ------------- end 

to

class product::productscontroller < applicationcontroller   ------------- end 

even routes needs changed. if want products controller inside namespace product mentioned in question, have declare routes shown below.

namespace :product     resources :products end
