'ForeignRelatedObjectsDescriptor'对象没有属性'all'

Question

我正在将我的Web应用程序移动到Django 1.7,我有一个非常好奇的错误,也许你们中的一个人知道正在发生.

class Product(models.Model):
    title = models.CharField(max_lenght=100)
    slug = models.SlugField()
    content = models.TextField()

class Gallery(models.Model):
    product = models.ForeignKey(Product, related_name="images")
    original = models.ImageField()

class MyView(DetailView):
    model = Product

   def get_context_data(self, **kwargs):
       ....
       # My error is here, when use this context and parse template
       context["galleries"] = Product.images.all()

给以下错误消息:

'ForeignRelatedObjectsDescriptor' object has no attribute 'all'
    response = wrapped_callback(request, *callback_args, **callback_kwargs)

Answer 1

尝试:

context["galleries"] = self.object.images.all()

您需要在Product模型的特定实例上调用它,该实例应该是您的对象.
