📖 Usage Examples

Public API

# Before (v0.1.0)
from sqlmodel_crud_utils.sync import get_row, update_row
from sqlmodel_crud_utils.a_sync import get_row as a_get_row

# After (v0.2.0)
from sqlmodel_crud_utils import get_row, update_row, a_get_row

Exception Handling

from sqlmodel_crud_utils import RecordNotFoundError, get_row

try:
    success, user = get_row(id_str=999, session=session, model=User)
    if not success:
        raise RecordNotFoundError(model=User, id_value=999)
except RecordNotFoundError as e:
    print(f"Not found: {e}")

Transactions

from sqlmodel_crud_utils import transaction, write_row, update_row

with transaction(session) as tx:
    user = write_row(User(name="Alice"), tx)
    update_row(user.id, {"email": "alice@example.com"}, User, tx)
    # Auto-commits on success, rolls back on error

Audit Trails

from sqlmodel import SQLModel, Field
from sqlmodel_crud_utils import AuditMixin

class User(SQLModel, AuditMixin, table=True):
    id: int = Field(primary_key=True)
    name: str
    # Automatically gets: created_at, updated_at, created_by, updated_by

Soft Deletes

from sqlmodel import SQLModel, Field
from sqlmodel_crud_utils import SoftDeleteMixin

class Product(SQLModel, SoftDeleteMixin, table=True):
    id: int = Field(primary_key=True)
    name: str
    # Automatically gets: is_deleted, deleted_at, deleted_by

# Usage
product.soft_delete(user="admin")  # Mark as deleted
product.restore()  # Restore
