Generating Migrations just got easier for me

I wanted to add a column "content" to the user's table. Most of us run the following to create a migration:

script/generate migration addContentToUsers


That creates a migration with the following:

class AddContentToUsers < ActiveRecord::Migration
  def self.up
  end

  def self.down
  end
end



What's generated is pretty green, so we'd have to add some add_column/remove_column statements like so:

class AddContentToUsers < ActiveRecord::Migration
  def self.up
     add_column :users, :content, :text
  end


Lots of not needed work. Why not just enter what we want onto the commandline when we run our migration? Enter the cool generator way of creating a simple migration:

script/generate migration AddContentToUsers content:string


This generates a sweet, simple migration like this:

class AddContentToUsers < ActiveRecord::Migration
  def self.up
    add_column :users, :content, :string
  end

  def self.down
    remove_column :users, :content
  end
end


Hot. Thanks for pointing this out l4rk
