title: How to properly use the "choices" field option in Django
body: <p>I'm reading the tutorial here: <a href="https://docs.djangoproject.com/en/1.5/ref/models/fields/#choices">https://docs.djangoproject.com/en/1.5/ref/models/fields/#choices</a>
  and i'm trying to create a box where the user can select the month he was born in. What I tried was</p>
  
  <pre><code> MONTH_CHOICES = (
      (JANUARY, "January"),
      (FEBRUARY, "February"),
      (MARCH, "March"),
      ....
      (DECEMBER, "December"),
  )
  
  month = CharField(max_length=9,
                    choices=MONTHS_CHOICES,
                    default=JANUARY)
  </code></pre>
  
  <p>Is this correct? I see that in the tutorial I was reading, they for some reason created variables first, like so</p>
  
  <pre><code>FRESHMAN = 'FR'
  SOPHOMORE = 'SO'
  JUNIOR = 'JR'
  SENIOR = 'SR'
  </code></pre>
  
  <p>Why did they create those variables? Also, the MONTHS_CHOICES is in a model called People, so would the code I provided create a "Months Choices) column in the database called called "People" and would it say what month the user was born in after he clicks on of the months and submits the form? </p>
