Django HVAD和ForeignKey

我有一个简单的应用程序：

class NamedModel(TranslatableModel):
    code = models.CharField(max_length=120)

    translations = TranslatedFields(
        name=models.CharField(max_length=256),
        description=models.TextField()
    )

    class Meta:
        abstract = True


class Product(NamedModel):
    translations = TranslatedFields()


class Report(TranslatableModel):
    quantity = models.DecimalField(max_digits=20, decimal_places=6)
    inv = models.ForeignKey(Inv)
    translations = TranslatedFields(
        product=models.ForeignKey(Product)
    )

然后，从shell I创建一些实例：

product = Product.objects.language('en').create(name='asd', description='asd', code='asd')

inv = Inv.objects.create(code='xxx')

report = Report.objects.language('en').create(quantity=1, inv=inv, product=product)

如果我键入：len（Report.objects.language（'en'）.all（）），我会得到1，但当我尝试此操作时：

Report.objects.language('en').all()

我得到：

NoTranslationError: Accessing a translated field requires that the instance has a translation loaded, or a valid translation in current language (None) loadable from the database

您有什么建议吗？

您需要明确设置当前会话的活动语言。 参见Django文档

from django.utils import translation

user_language = 'en'
translation.activate(user_language)
