关于python:peewee-获取-crud-操作对应的-sql-语句

peewee 有两种获取 crud 操作对应的 sql 语句的形式：

• 应用 logging，代理 peewee，以输入日志的形式打印 sql
• 拜访 modelinsert 等类实例的 __str__ 办法

我当初要讲的是后者：

获取插入操作的 sql

def save_record(user_id: int, long_url: str, short_uuid: str) -> InsertResult:
    insert_obj = TinyUrl.insert(
        user_id=user_id,
        long_url=long_url,
        long_url_hash=md5_helper.get_string_md5(long_url),
        short_uuid=short_uuid
    )

    sql = str(insert_obj)
    started_at = time.time()
    row_id = insert_obj.execute()
    ended_at = time.time()

    return InsertResult(
        tracks=[
            DBCrudTrack(
                sql=sql,
                pay_time=ended_at - started_at
            )
        ],
        row_id=row_id
    )

获取查问操作的 sql

def get_row_by_user_id_long_url_hash(user_id: int, long_url_hash: str) -> SelectResult:
    query: ModelSelect = TinyUrl.select().where((TinyUrl.user_id == user_id) &
        (TinyUrl.long_url_hash == long_url_hash)
    )
    sql = str(query)

    start_at = time.time()
    rows: list[dict] = list(query.dicts()
    )
    end_at = time.time()

    return SelectResult(
        tracks=[
            DBCrudTrack(
                sql=sql,
                pay_time=end_at - start_at
            )
        ],
        rows=[Row(**row)
            for row in rows
        ]
    )
