title: What kind of model field to use for a two dimensional array in Django?
body: <p>I'm new to Django and I'm trying to create a Battleship game. I want to create a model for my battleship board, which is going to be 10 rows and 10 columns, with each spot having a coordinate of [x,y]. I'm not sure which model field to use though. So far, this is the code I have for my Board class:</p>
  
  <pre><code>class Board(models.Model):
      ships_left = models.IntegerField()
      available_spots = models.???  #This is to contain [x,y] coordinates of open spots
  </code></pre>
