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

Question

Hello I am absolute newbie in rails. creating some application but stuck on some point.

The problem is I want to insert data in products as per user id but it is saying:

uninitialized constant ProductController

Here is my route file:

Rails.application.routes.draw do
  #devise_for :users
  devise_for :users, :controllers => { :registrations => 'users/registrations' }
  resources :dashboard
  root to: "home#index"

  namespace :user do
    resources :users
  end

  resources :product
end

here is my 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 is my new.html.erb code:

<h2>Add Product</h2>

<%= form_for(resource, :as => resource_name, :url => user_registration_path) do |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 this thing is wrong too:

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

How I can make all the parts to one? my goal is to take use to a new page add product name and redirect to product list page.

Rename your controller as products_controller.rb

Then change

class Product::ProductController < ApplicationController
  -------------
end

to

class Product::ProductsController < ApplicationController
  -------------
end

Even routes needs to be changed. If you want products controller inside a namespace product as you mentioned in your question, then you have to declare routes as shown below.

namespace :product do
    resources :products
end
