列表排序

此方法与 select_models() 方法类似，但增加了排序功能

select_models_order

from typing import Sequence

from sqlalchemy_crud_plus import CRUDPlus

from sqlalchemy import DeclarativeBase as Base
from sqlalchemy.ext.asyncio import AsyncSession


class ModelIns(Base):
    # your sqlalchemy model
    pass


class CRUDIns(CRUDPlus[ModelIns]):
    async def create(self, db: AsyncSession) -> Sequence[ModelIns]:
        return await self.select_models_order(db, sort_columns=['name', 'age'], sort_orders=['asc', 'desc'])

API

async def select_models_order(
    self,
    session: AsyncSession,
    sort_columns: str | list[str],
    sort_orders: str | list[str] | None = None,
    *whereclause: ColumnExpressionArgument[bool],
    **kwargs,
) -> Sequence[Row | RowMapping | Any] | None:

Parameters:

Name	Type	Description	Default
session	AsyncSession	数据库会话	必填
sort_columns	str|list[str]	应用排序的单个列名或列名列表	必填
sort_orders	str|list[str]|None	单个排序顺序（asc 或 desc）或与 sort_columns 中的列相对应的排序顺序列表。 如果未提供，则默认每列的排序顺序为 asc	None
*whereclause	ColumnExpressionArgument[bool]	等同于 SQLAlchemy where
**kwargs		条件过滤，将创建条件查询 SQL

Returns:

Type	Description
Sequence[Row[Any]|RowMapping|Any]	模型实例序列
