Django with postgres backend attribute error
SOLVED
Currently I am working on my first django project. The DB is modeling the structure of an Abaqus input file. Here is the Code
from django.db import models as m
import django.contrib.postgres as pg
class node(m.Model):
inputfile = m.CharField(max_length = 255)
source_id = m.IntegerField()
source_sim = m.CharField(max_length = 255)
coordinates = pg.fields.ArrayField(m.FloatField(), size = 3)
When I call manage.py makemigrations (Or just python) it gives me the error message:
AttributeError: module 'django.contrib.postgres' has no attribute 'fields'
When I import ArrayField in a testscript, it works:
from django.contrib.postgres.fields import ArrayField
from django.db import models as m
a = ArrayField(m.FloatField(), size=3)
print(a)
>>><django.contrib.postgres.fields.array.ArrayField>
I was able to migrate my classes into a TestDB without the ArrayField.
My Python version 3.7.1, my Django version is 2.1.3
What's my mistake?
edit: Style&formatting. Thanks to suggestions.
Edit: Solved, but cant find how to flag that

This is basic python: as the error says,fieldsisn't an attribute so you have to do as you did on the command-line:from django.contrib.postgres.fields import ArrayFieldorimport django.contrib.postgres.fields as pg_fieldsand thenpg_fields.ArrayFieldwill work.
