mysql - Peewee 选择十进制字段？

Question

我有以下使用 Peewee 库的请求:

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

其中 Products.price 是 MySQL 中 decimal(15,4) 类型的字段

这是模型:

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'

当我运行上述查询时，出现错误:

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

怎么了？

我认为 Peewee 中存在 Python 3 错误。如果此补丁解决了您的问题，请告诉我:
