title: How do I include related model fields using Django Rest Framework?
body: <p>Let's say that we have the following model:</p>
  <pre><code>class Classroom(models.Model):
      room_number = [...]
  
  class Teacher(models.Model):
      name = [...]
      tenure = [...]
      classroom = models.ForeignKey(Classroom)
  </code></pre>
  <p>Let's say that instead of getting a result like this per the ManyRelatedPrimaryKeyField function:</p>
  <pre><code>{
      &quot;room_number&quot;: &quot;42&quot;, 
      &quot;teachers&quot;: [
          27, 
          24, 
          7
      ]
  },
  </code></pre>
  <p>have it return something that includes the full related model representation like:</p>
  <pre><code>{
      &quot;room_number&quot;: &quot;42&quot;, 
      &quot;teachers&quot;: [
          {
             'id': 27,
             'name': 'John',
             'tenure': True
          }, 
          {
             'id': 24,
             'name': 'Sally',
             'tenure': False
          }, 
      ]
  },
  </code></pre>
  <p>Is this possible? If so, how? And is this a bad idea?</p>
