Problem :

  2. F:\RubyProjects\chapterone>rails script/generate controller
    greeting

  3. after that i edit greeting_controller.rb

class GreetingController < ApplicationController
def index
@welcome_message=“Welcome to your first rail application”
end
end

  1. then i create a index.html.rb file in app/view/greeting folder

<%=@welcome_message %>

  1. then i open browser http:\localhost:3000/greeting

here i got a error


MissingSourceFile in GreetingController#index

So can any one suggest me , how to get out of this error.

I think the file extension is causing the problem. Try to change it to
.html.erb.

Don’t forget to post your future Rails question on the Ruby on Rails
forum[0]. :wink:

Thanks Yaser , problem solved by changing file extension.

Below is my query,

I am trying to develop simple shoppingcart application.

  1. created rails application by

projects>rails ShoppingCart

  1. then created database for shopping cart table-products

fields are- id, title, description, price, expiredate

  1. created one Product scaffold by

projects>ShoppingCart>ruby script/generate scaffold Product title:string
description:text price:decimal expiredate:datetime

4)then i browse and did some new, edit, delete operations.

  1. Now i want to add one field to my products table- image_url.
    then fields are- id, title, description, price, expiredate, image_url.

I want to overwrite Product sacffold so that when i browse products page
it should display me added field i.e image_url.

Is there any migration related issue?
