Much thanks for responding to my cry for help! I will make the
suggested changes and correctionns. Thanks much.
Actually, I did adhere to Django's typical workflow as you hinted to:
python manage.py makemigrations
python manage.py migrate
But when I examined the 0001_initial.py file in the migrations folder:
from django.db import models, migrations
class Migration(migrations.Migration):
dependencies = [
]
operations = [
migrations.CreateModel(
name='ActiveContracts',
fields=[
('id', models.AutoField(serialize=False, verbose_name='ID', primary_key=True, auto_created=True)),
],
),
migrations.CreateModel(
name='AddressBook',
fields=[
('id', models.AutoField(serialize=False, verbose_name='ID', primary_key=True, auto_created=True)),
],
),
migrations.CreateModel(
name='Agents',
fields=[
('id', models.AutoField(serialize=False, verbose_name='ID', primary_key=True, auto_created=True)),
],
),
migrations.CreateModel(
name='ArchivedContracts',
fields=[
('id', models.AutoField(serialize=False, verbose_name='ID', primary_key=True, auto_created=True)),
],
),
migrations.CreateModel(
name='Genus',
fields=[
('id', models.AutoField(serialize=False, verbose_name='ID', primary_key=True, auto_created=True)),
],
),
migrations.CreateModel(
name='ManagementUnits',
fields=[
('id', models.AutoField(serialize=False, verbose_name='ID', primary_key=True, auto_created=True)),
],
),
migrations.CreateModel(
name='ProductionUnits',
fields=[
('id', models.AutoField(serialize=False, verbose_name='ID', primary_key=True, auto_created=True)),
],
),
migrations.CreateModel(
name='Products',
fields=[
('id', models.AutoField(serialize=False, verbose_name='ID', primary_key=True, auto_created=True)),
],
),
migrations.CreateModel(
name='SoilProfiles',
fields=[
('id', models.AutoField(serialize=False, verbose_name='ID', primary_key=True, auto_created=True)),
('comment', models.TextField(default='Not provided')),
],
),
]
ONLY the id field is being auto-generated. As my-level of Django skiils I am not
sure how identify the source of the problem. The models have correct names
so manage.py is "model-aware (assume correct env setup)". I was looking
here (https://realpython.com/blog/python/digging-deeper-into-migrations) for more info on
migration and was considering to edit migration file to setup the database tables. BUT
I AM NOT CLEAR ON THE IMPLICATIONS GOING FORWARD FOR ADMIN INTERFACE
and so. I shall see where this path leads to - hopefully a solution and a deeper understanding of
the Django framework.
