# Migrating to v4.0

This page covers every breaking change introduced in **v4.0** and the steps required to update your code.

## Database
|
|
|
|
### `lock_tables` now takes a `session_maker` instead of a `session`
|
|
|
|
The first argument of `lock_tables` changed from an `AsyncSession` instance to an `async_sessionmaker`.
|
|
The function creates and manages its own **dedicated session** internally, yielding it to the caller.
|
|
|
|
=== "Before (`v3`)"
|
|
|
|
```python
|
|
from fastapi_toolsets.db import lock_tables, LockMode
|
|
|
|
async with lock_tables(session=session, tables=[User, Account]):
|
|
user = await UserCrud.get(session, [User.id == 1])
|
|
user.balance += 100
|
|
|
|
# With a custom lock mode
|
|
async with lock_tables(session=session, tables=[Order], mode=LockMode.EXCLUSIVE):
|
|
await process_order(session, order_id)
|
|
```
|
|
|
|
=== "Now (`v4`)"
|
|
|
|
```python
|
|
from fastapi_toolsets.db import lock_tables, LockMode
|
|
|
|
async with lock_tables(session_maker=session_maker, tables=[User, Account]) as session:
|
|
user = await UserCrud.get(session, [User.id == 1])
|
|
user.balance += 100
|
|
|
|
# With a custom lock mode
|
|
async with lock_tables(
|
|
session_maker=session_maker, tables=[Order], mode=LockMode.EXCLUSIVE
|
|
) as session:
|
|
await process_order(session, order_id)
|
|
```
