关于python:peewee-创建联合索引

class TinyUrl(Model):    id = BigAutoField()    user_id = IntegerField(null=False)    short_uuid = CharField(max_length=255, null=False, help_text='长度为 6 位')    long_url_hash = CharField(max_length=64, null=False)    long_url = CharField(max_length=2048, null=False)    created_at = DateTimeField(        null=False,        constraints=[SQL('DEFAULT CURRENT_TIMESTAMP')],        help_text='应用数据库工夫'    )    updated_at = DateTimeField(        null=False,        constraints=[            SQL('DEFAULT CURRENT_TIMESTAMP'),            SQL('ON UPDATE CURRENT_TIMESTAMP'),        ]    )    class Meta:        database = db        table_name = 'tiny_url'        indexes = (            (('short_uuid',), True),            (('user_id', 'long_url_hash'), True),        )

应用 indexes 就能够了
