Question

In my Rails application I have created a controller to get data from database which also includes params in model as follows.

The problem is that there are no html pages in views folder.. Do I need to run the controller??? I want the output i json format.. How are the html pages created and where can i see my json format of data…

# shoppingDemo.rb (controller)
class ShoppingDemo < ApplicationController
  def index
    @lists=products.all;
    respond_to do |format|
      format.html
      format.json { render json: @lists}
    end
  end

  def show
    @products = products.find(params[:prod_id])

    respond_to do |format|
      format.html # show.html.erb
      format.json { render json: @products }
    end
  end
end

# products(model)
class products < Activerecord::Base
  attr_accessible :model_name, :brand_name, :price, :discount, :qty_available
end

What is the next step to create html pages or to see my data from database in json format.

Answer 1

You should fix some issues:

1) in Model

class Product

2) in Controller

@lists = Product.all

@products = Product.find(params[:id])

3) You should create routes in config/routes.rb

resources :products

It will create routes for index, show, new, create, update, destroy actions. Read more here.

After that you can access your products list through http request on http://localhost:3000/products and show your product with id=1 on http://localhost:3000/products/1
