I'm making a terminal command for my Django app:
from django.core.management.base import BaseCommand, CommandError
from django.core.exceptions import FieldDoesNotExist
from django.apps import apps
class Command(BaseCommand):
def add_arguments(self, parser):
parser.add_argument(
"--app",
dest="app",
required=True,
)
parser.add_argument(
"--model",
dest="model",
required=True,
)
parser.add_argument(
"--col",
dest="col",
required=True,
)
def handle(self, *args, **options):
app_label = options.get('app')
model_name = options.get('model')
column_name = options.get('col')
try:
model = apps.get_model(app_label=app_label, model_name=
model_name)
except LookupError as e:
msg = 'The model "%s" under the app "%s" does not exist!' \
% (model_name, app_label)
raise CommandError(msg)
try:
column = model._meta.get_field(column_name)
except FieldDoesNotExist as e:
msg = 'The column "%s" does not match!' % column_name
raise CommandError(msg)
else:
print(column, type(column))
# Do stuff here with the column, model.
Right now, `column` is `<django.db.models.fields.IntegerField:
column_name>`. I want this instance of `model` to have `column_name` set to
`100`. How can I set and save this instance in this manner?
