💻 Usage Examples

Creating a Model

from sqlsymphony_orm.datatypes.fields import IntegerField, CharField
from sqlsymphony_orm.models.orm_models import Model
from sqlsymphony_orm.queries import raw_sql_query
from sqlsymphony_orm.database.connection import SQLiteDBConnector


class User(Model):
    __tablename__ = "Users"
    __database__ = "users.db"

    id = IntegerField(primary_key=True)
    name = CharField(max_length=32, unique=True, null=False)

    def __repr__(self):
        return f"<User {self.id} {self.name}>"

connector = SQLiteDBConnector().connect()


@raw_sql_query(connector=connector)
def create_table(name: str):
    return 'CREATE TABLE IF NOT EXISTS %s (id INTEGER, name TEXT NOT NULL)' % (name,)


create_table('Memo')


user = User(name="Charlie")
user.save()

user2 = User(name="Carl")
user2.save()

user2.update(name="Bobby")

user3 = User(name="John")
user3.save()

user3.delete()

print(user.objects.fetch())
print(user.objects.filter(name="Bobby"))

user.view_table_info()

Performing CRUD Operations

Create a new record

user = User(name='Charlie')
user.save()

user2 = User(name='John')
user2.save()

print(user.objects.fetch())

Update record

user2 = User(name="Carl")
user2.save()

user2.update(name="Bobby")

print(user.objects.fetch())

Delete record

user = User(name="Charlie")
user.save()

user2 = User(name="Carl")
user2.save()

user3 = User(name="John")
user3.save()

user3.delete() # delete user3
# OR
user3.delete(field_name="name", field_value="Carl") # delete user2

print(user.objects.fetch())

Filter

user = User(name="Charlie")
user.save()

user2 = User(name="Carl")
user2.save()

user2.update(name="Bobby")

user3 = User(name="John")
user3.save()

user3.delete()

print(user.objects.fetch())
print(user.objects.filter(name="Bobby"))
