title: Can I pass default value to rails generate migration?
body: <p>I want to know if I can pass <strong>a default value</strong> to the <code>rails g migration</code> command. Something like:</p>
  
  <pre><code> $ rails generate migration add_disabled_to_users disabled:boolean:false #where false is default value for disabled attribute
  </code></pre>
  
  <p>in order to generate:</p>
  
  <pre><code>class AddDisabledToUsers &lt; ActiveRecord::Migration
    def change
      add_column :users, :disabled, :boolean, default: false
    end
  end
  </code></pre>
