Hello to all , please Give me solution…  
I am new in ruby development, so please me, i am asking a very simple  
query.

Problem :  
I created a simple greeting application

1. F:\RubyProjects\>rails chapterone

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.

Thank you,  
Vikas G…

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]. 😉

I have repeat your steps exactly as you presented them and everything  
is working fine as expected, unlike in your case.  
There is something missing in your presentation.  
You have to give us more details to be able to help you with this  
unexpected behavior.

Thanks Yaser , problem solved by changing file extension.

but new query arise to me  
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.

give me steps to solve this problem.  
Is there any migration related issue?

Vikas
