Tortoise-ORM BlackSheep 集成

Tortoise-ORM BlackSheep integration

我们有一个轻量级的集成工具 tortoise.contrib.blacksheep，其中包含一个函数 register_tortoise，该函数在启动时设置 Tortoise-ORM，并在拆卸时进行清理。

BlackSheep 是一个异步网络框架，用于使用 Python 构建基于事件的 web 应用程序。

请查看 BlackSheep 样例，并参考 Pydantic 序列化 教程。

We have a lightweight integration util tortoise.contrib.blacksheep which has a single function register_tortoise which sets up Tortoise-ORM on startup and cleans up on teardown.

BlackSheep is an asynchronous web framework to build event based web applications with Python.

See the BlackSheep 样例 & have a look at the Pydantic 序列化 tutorials.

You can configure using only one of config, config_file and (db_url, modules).

Parameters:
app

config=None

Dict containing config:

Example

{
    'connections': {
        # Dict format for connection
        'default': {
            'engine': 'tortoise.backends.asyncpg',
            'credentials': {
                'host': 'localhost',
                'port': '5432',
                'user': 'tortoise',
                'password': 'qwerty123',
                'database': 'test',
            }
        },
        # Using a DB_URL string
        'default': 'postgres://postgres:qwerty123@localhost:5432/events'
    },
    'apps': {
        'models': {
            'models': ['__main__'],
            # If no default_connection specified, defaults to 'default'
            'default_connection': 'default',
        }
    }
}

config_file=None

Path to .json or .yml (if PyYAML installed) file containing config with same format as above.

db_url=None

Use a DB_URL string. See DB_URL

modules=None

Dictionary of key: [list_of_modules] that defined “apps” and modules that should be discovered for models.

generate_schemas=False

True to generate schema immediately. Only useful for dev environments or SQLite :memory: databases

add_exception_handlers=False

True to add some automatic exception handlers for DoesNotExist & IntegrityError. This is not recommended for production systems as it may leak data.
