Question

我正在尝试制作一个django电子商务应用，其中的产品有不同的变化。例如，产品T恤有不同的颜色（红色，绿色......）。对于每个变体，我想上传至少三个不同的图像。目前，我每个版本只能上传一张图片。

我的应用代码：

class Product(models.Model):
    title = models.CharField(max_length=120)
    price = models.DecimalField(decimal_places=2, max_digits=20)
    default_image = models.ImageField(upload_to=image_upload_to_prod, blank=True, null=True)
    slug = models.SlugField(blank=True, null=True)

    def __str__(self):
        return self.title

    def get_absolute_url(self):
        return reverse('Products:SingleProduct', kwargs={'pk': self.pk})

class Variation(models.Model):
    product = models.ForeignKey(Product, on_delete=models.CASCADE)
    title = models.CharField(max_length=120)
    price = models.DecimalField(decimal_places=2, max_digits=20)
    DEFAULT = 'DEFAULT'
    RED = 'RED'
    BLUE = 'BLUE'
    TYP = (
        (DEFAULT, 'DEFAULT'),
        (RED, 'RED'),
        (BLUE, 'BLUE'),
    )
    color = models.CharField(max_length=100, choices=TYP, default=DEFAULT)
    image = models.ImageField(upload_to=upload_location, blank=True, null=True)

    def get_price(self):
        if self.sale_price is not None:
            return self.sale_price
        else:
            return self.price

   def get_image(self):
       if self.image is not None:
           return self.product.default_image
       else:
           return self.image

   def get_absolute_url(self):
       return self.product.get_absolute_url()

def upload_location(object, filename):
    title = object.product.title
    slug = slugify(title)
    return "products/%s" % (slug)

如何添加多个图像并在模板中显示它们？

更新模型并使用单独的图像类

class ProductImage(models.Model):
    image = models.ImageField(upload_to=image_upload_to_prod, blank=True, null=True)

class Product(models.Model):
    title = models.CharField(max_length=120)
    price = models.DecimalField(decimal_places=2, max_digits=20)
    default_image = models.ForeignKey(ProductImage)
    slug = models.SlugField(blank=True, null=True)

添加一个产品变异django电子商务应用程序的多个图像
