Peewee：使用其他名称更改“ Id”字段

Question

Peewee模型上是否可以将名为“ id”的默认主键更改为另一个名称？

Answer 1

A couple ways...

Auto-incrementing integer field named "pk":

class MyModel(Model):
    pk = PrimaryKeyField()
    other_field = TextField()

Varchar primary key:

class MyModel(Model):
    data = CharField(primary_key=True)

Multi-column primary key:

class MyModel(Model):
    key = CharField()
    value = CharField()

    class Meta:
        primary_key = CompositeKey('key', 'value')
