如何使用用户id rails 4在产品表中插入数据

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

你好,我是铁杆的绝对新手。创建一些应用程序,但坚持一些点。

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

问题是我想按照用户ID在产品中插入数据但是它说:

uninitialized constant ProductController

未初始化的常量ProductController

Here is my route file:

这是我的路线档案:

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:

这是我的产品控制器,即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:

这是我的new.html.erb代码:

<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:

我知道这件事也是错的:

<%= 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.

我怎样才能将所有零件都制成一个?我的目标是使用新页面添加产品名称并重定向到产品列表页面。

#1

Rename your controller as products_controller.rb

将控制器重命名为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.

甚至需要改变路线。如果你想在产品命名空间产品中使用产品控制器,就像你在问题中提到的那样,那么你必须如下所示声明路由。

namespace :product do
    resources :products
end

#2

Rename your controller as products_controller.rb

将控制器重命名为products_controller.rb

Then change

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

to

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

and the routes file should be changed as this

并且路由文件应该更改为此

  namespace :product do
    resources :products
  end

instead of resources :product

而不是资源:产品
