SomeModel.objects.filter(id=id).delete()
Noobie Nareshhhh
SomeModel.objects.filter(id=id).delete()The following is a function to drop all the public tables from the
database using: python manage.py dropalltables
1 - In the app that contains the models, create:
management/commands/dropalltables.py
The tree structure should look like this:
my_app
|---management
|---commands
|---dropalltables.py
2 - in dropalltables.py write:
from django.core.management.base import BaseCommand, CommandError
from django.db import connection
class Command(BaseCommand):
help = "Drop all the tables from the database"
def handle(self, *args, **options):
try:
print("Do you really want to DROP (delete) ALL THE PUBLIC TABLES from the database?")
choice = input("type the following sentence to confirm: yes, drop all! ")
if choice.lower() == "yes, drop all!":
cursor = connection.cursor()
cursor.execute("SELECT table_name FROM INFORMATION_SCHEMA.tables where table_schema = 'public';")
parts = ('DROP TABLE IF EXISTS %s CASCADE;' % table for (table,) in cursor.fetchall())
sql = '\n'.join(parts) + '\n'
connection.cursor().execute(sql)
print("Done! There are no more public tables in the database.")
else:
print("You have chosen not to remove the tables.")
except Exception as e:
raise CommandError(f"Error: {e}")
3 - In the terminal type:
python manage.py dropalltables
python manage.py shell
>> from {app_name}.models import {model_name}
>> {model_name}.objects.all().delete()
