Run it to generate a new migration 1)rails generate migration add_price_to_product price:decimal

2)Added following to migration file

class AddPriceToProduct < ActiveRecord::Migration def self.up add_column :products, :price, :decimal, :precision => 8, :scale => 2, :default => 0 end def self.down remove_column :products, :price end end rake db:migrate                                               Then ran "rake db:migrate",it created a new columns in table products with name "price" ,but i didnt change the view(didnt create a filed with name "price")

Why

Thanks

Migrations don't do that (you can create migrations to do all sorts of things, not necessarily related to new fields for a view).
