InterfaceError неизвестный тип <class 'decimal.Decimal'> для arg 10

Я пытаюсь получить некоторые данные из моей базы данных. Это отлично работает на моей локальной машине. Но при развертывании на Google App Engine это дает мне ошибкуInterfaceError неизвестный тип <class 'decimal.Decimal'> для arg 10

Очевидно, что это не удается, потому что он говорит, что unit.min_quantity десятичное. Но я не объявим его как Decimal в моих моделях:

class Unit_type(models.Model): 
    unit_name = models.CharField(max_length=145) 
    department = models.ForeignKey(Department) 
    min_quantity = models.IntegerField(blank=True, null=True) 

    class Meta: 
     verbose_name = 'unit type' 

    def __unicode__(self): 
     return self.unit_name

Когда я заполняю заявление и выполнить его вручную в Google Cloud SQL, он работает. Может ли кто-нибудь помочь мне с этой неприятной проблемой?

Благодаря

Возможно, вы должны поместить max_digits для min_quantity – catherine

У меня такая же проблема, что и запрос Google Cloud SQL с использованием SQLAlchemy с десятичным параметром. Например: 'm.ProductPrice.query.filter (m.ProductPrice.volume <= decimal.Decimal ('1.23')). All()' вызывает InterfaceError. –

Обходной путь, который я нашел, - это изменить параметр от десятичной до str, например: 'm.ProductPrice.query.filter (m.ProductPrice.volume <= str (decimal.Decimal ('1.12'))).() ' –

Google Cloud SQL DBAPI в настоящее время не поддерживает decimal.Decimal тип, хотя вы можете обезьяна патч его:

import decimal 
from google.storage.speckle.proto import jdbc_type 

from google.storage.speckle.python.api import converters 
from google.storage.speckle.python.api import rdbms 
from google.storage.speckle.python.api import rdbms_googleapi 

rdbms._PYTHON_TYPE_TO_JDBC_TYPE[decimal.Decimal] = jdbc_type.DECIMAL 
converters.conversions[decimal.Decimal] = converters.Any2Str 
converters.conversions[jdbc_type.DECIMAL] = decimal.Decimal

Существует проблема авторизовались here где представитель Google предоставил патч выше и указали, что они работают над исправлением для этого.

Спасибо за ваш ответ, я попробую его на нашем тестовом сервере позже сегодня. –
