ArrayField not recognized?

Question

I have the following error message:

AttributeError: 'module' object has no attribute 'ArrayField'

Here is the relevant code segment:

from __future__ import unicode_literals
from django.db import models
from django.contrib.postgres.fields import ArrayField

class TypeStatistics(models.Model):
    bots_array = models.ArrayField(models.CharField(max_length=50), blank=True)

Any idea what can be causing this?

Answer 1

Two things, first make sure that you are using Django version >= 1.8 then change the following line:

bots_array = models.ArrayField(models.CharField(max_length=50), blank=True)

to

bots_array = ArrayField(models.CharField(max_length=50), blank=True)

the django.db.models does not have an ArrayField but you have imported ArrayField from contrib postgresql so that's what you should be using.
