Django ArrayField - a PostgreSQL-specific field Specifying the maximum size of an ArrayField
Example
from django.db import models, IntegerField
from django.contrib.postgres.fields import ArrayField
class IceCream(models.Model):
scoops = ArrayField(IntegerField() # we'll use numbers to ID the scoops
, size=6) # our parlor only lets you have 6 scoops
When you use the size parameter, it's passed through to postgresql, which accepts it and then ignores it! Thus it's quite possible to add 7 integers to the scoops field above using the postgresql console.
