Django - AttributeError: module 'os' has no attribute 'environment'

Question

In the context of learning Django, I need to populate Sqlite with random data using Faker module.

Several models have been created under models.py :

from django.db import models

class Topic(models.Model):
    top_name = models.CharField(max_length=264,unique=True)

    def __str__(self):
        return self.top_name

class Webpage(models.Model):
    topic = models.ForeignKey(Topic,on_delete=models.DO_NOTHING)
    name = models.CharField(max_length=264,unique=True)
    url = models.URLField(unique=True)

    def __str__(self):
        return self.name

class AccessRecord(models.Model):
    name = models.ForeignKey(Webpage,on_delete=models.DO_NOTHING)
    date = models.DateField()

    def __str__(self):
        return str(self.date)

To randomly populate these models, I'm using the following script (populate_first_app.py):

import os
os.environment.setdefault('DJANGO_SETTINGS_MODULE','first_project.settings')

import django
django.setup()

##FAKE POP SCRIPT
import random
from first_app.models import AccessRecord,Webpage,Topic
from faker import Faker


fakegen = Faker()
topics = ['Search','Social','Marketplace','News','Games']

def add_topic():
    t = Topic.objects.get_or_create(top_name=random.choice(topics))[0]
    t.save()
    return t

def populate(N=5):
    for entry in range(N):
        top = add_topic()
        fake_url = fakegen.url()
        fake_date = fakegen.date()
        fake_name = fakegen.company()

        webpg = Webpage.objects.get_or_create(topic=top,url=fake_url,name=fake_name)[0]

        acc_rec = AccessRecord.objects.get_or_create(name=webpg,date=fake_date)[0]

if __name__ == '__main__':
    print('populating script!')
    populate(20)
    print('populating complete')

When I'm running populate_first_app.py, I got the following error:

AttributeError: module 'os' has no attribute 'environment'

Using Visual Studio Code (v1.39.2), I'm stuck.

Visual code is highlighting error on following lines:

t = Topic.objects.get_or_create(top_name=random.choice(topics))[0]

Class 'Topic' has no 'objects' memberpylint(no-member)

I installed pylint using the following command:

pip3 install pylint-django

But still stuck.

Answer 1

The call should be

os.environ.setdefault('DJANGO_SETTINGS_MODULE','first_project.settings')

For more details you can see previous questions, like this one: Is it safe to use os.environ.setdefault?
