title: Modify schema.rb in rails application
body: <p>I am new to rails. </p>
  
  <p>I want to create an Article model. So I run,</p>
  
  <p>rails g model Article name:string context:string</p>
  
  <p>Instead of <strong>content</strong> I type in <strong>context</strong>, Is there a way to update the schema.rb file that gets generated?</p>
  
  <p>I would like the articles table to have name and content columns.</p>
