Peewee选择Decimal字段？

Question

我使用Peewee库提出以下请求：

return Products.select(Products.price, Products.sku, Products.manufacturer_id).where(Products.sku == article).get()

其中Products.price是MySQL中类型为decimal(15,4)的字段

这是型号：

class Products(peewee.Model):
    product_id = IntegerField(primary_key=True)
    sku = peewee.CharField()
    model = peewee.CharField()
    price = peewee.DecimalField(max_digits=15, decimal_places=4)
    manufacturer_id = peewee.IntegerField()

    class Meta:
        database = get_db_connection()
        table_name = 'oc_product'

当我运行查询时如上所述，我收到错误：

Error has occurred: Cannot convert b'6403.0000' to Decimal

有什么问题？

我相信Peewee中有一个使用Python 3的错误。请告诉我这个补丁是否解决了您的问题：
