title: How to change migration file name? (Rails)
body: <p>I've got an error with the migration file name (it have to be <code>projects</code> instead <code>products</code>). I've called this: <code>20170131095212_add_title_to_products.rb</code> but it contains the correct table inside: </p>
  
  <pre><code>class AddReferenceToProducts &lt; ActiveRecord::Migration
      def change
          add_column :projects, :title, :string, length: 512
      end
  end
  </code></pre>
  
  <p>How I can change the migration file name correctly? 
  Ruby '2.3.0', Rails '4.2.6'.
  Thanks.</p>
