Django Postgres table partitioning not working with 'pgpartition' command

Question

I have a huge "Logs" postgres table being used extensively in my Django project. Logs table has more than 20 million records and its slowing down the queries and page load time is also increased. I am using below Django and Postgres versions:- Django: 4.0 Postgres: 13

I read about table partitioning and decided to use "django-postgres-extra" as I don't want to manage migration files.

I followed all the steps mentioned in below link but I am not able to create partitioned tables using "pgpartition" command. https://django-postgres-extra.readthedocs.io/en/master/table_partitioning.html

Am I missing something here? models.py changes:-

from django.db import models

from psqlextra.types import PostgresPartitioningMethod
from psqlextra.models import PostgresPartitionedModel
from psqlextra.manager import PostgresManager


class Logs(PostgresPartitionedModel):

    class PartitioningMeta:
        method = PostgresPartitioningMethod.RANGE
        key = ["ctime"]

    objects = PostgresManager()

    ctime = models.DateTimeField(auto_now_add=True)
    logname = models.CharField(max_length=20)
    builds = models.ForeignKey(Build)

settings.py

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.postgres',
    'psqlextra',
    'logs',
]


DATABASES = {
    'default': {
        'ENGINE': 'psqlextra.backend', 
        'NAME': 'logdb',
        'USER': 'root',
        'PASSWORD': 'crypt',
        'HOST': 'localhost',
        'PORT': 5432,
    }
}

PSQLEXTRA_PARTITIONING_MANAGER = 'logs.partition.manager'

Created a file named 'partition' under logs app and defined a manager object as per doc link above. partition.py

from dateutil.relativedelta import relativedelta
from logs.models import Logs

from psqlextra.partitioning import (
    PostgresPartitioningManager,
    PostgresCurrentTimePartitioningStrategy,
    PostgresTimePartitionSize,
    partition_by_current_time,
)
from psqlextra.partitioning.config import PostgresPartitioningConfig

manager = PostgresPartitioningManager([

    # 3 partitions ahead, each partition is one month
    # delete partitions older than 6 months
    # partitions will be named `[table_name]_[year]_[3-letter month name]`.
    PostgresPartitioningConfig(
        model=Logs,
        strategy=PostgresCurrentTimePartitioningStrategy(
            size=PostgresTimePartitionSize(months=1),
            count=1,
            max_age=relativedelta(months=1),
        ),
    ),
])

When I ran "python manage.py pgmakemigrations" command it created a migration file as below:- 0002_alter_log_managers.py

# Generated by Django 4.0.3 on 2022-05-19 12:22

from django.db import migrations
import psqlextra.manager.manager


class Migration(migrations.Migration):

    dependencies = [
        ('logs', '0001_initial'),
    ]

    operations = [
        migrations.AlterModelManagers(
            name='logs',
            managers=[
                ('objects', psqlextra.manager.manager.PostgresManager()),
            ],
        ),
    ]

But as soon as I run "pgpartition" command I get below error:-

python manage.py pgpartition

Not sure what I am missing here...
