title: Rails Fixtures - what do these mean?
body: <h3>Context</h3>
  
  <p>When I generate the fixture file, <code>rails generate model Post title:string text:text</code> it shows:</p>
  
  <pre><code>one:
    title: MyString
    text: MyText
  
  two:
    title: MyString
    text: MyText
  </code></pre>
  
  <h3>Question</h3>
  
  <p>I was wondering why are there 2, and why are they named "one" and "two".</p>
  
  <p><a href="http://api.rubyonrails.org/v2.3.8/classes/Fixtures.html" rel="noreferrer">Here</a> I see that names like "google", "rubyonrails", and "parent/child" are used; whereas, following the tutorial for generating the posts model, it generates just one and two...</p>
  
  <p>Upon more research, I found that I might also be interested in db/migrate files. My current theory is that these files create the structure of my data... so I'm not so sure what fixtures does.</p>
  
  <h3>Reason</h3>
  
  <p>I'm trying to create a "Student" model using </p>
  
  <pre><code>rails generate scaffold student
  </code></pre>
  
  <p>but it doesn't seem to have :name as one of its keys. I'm looking into fixtures to add data columns.</p>
