Question

在大量搜索之后，我似乎无法找到解决方案：我创建了一个新的端点，用于从“产品索引”中搜索商品

将Django oscar与django oscar api结合使用，以下是这些模型：

class Product(AbstractProduct):
   title = models.TextField(blank = True)

class ProductImage(AbstractProductImage):
    product = models.ForeignKey('catalogue.Product', on_delete=models.CASCADE)
    display_order = models.PositiveIntegerField()
    remote_image = models.URLField(blank=True)

views.py

class ItemSearchViewSet(mixins.ListModelMixin, viewsets.GenericViewSet):
    serializer_class = ItemSearchSerializer

    def get_queryset(self):
        request = self.request
        queryset = EmptySearchQuerySet()

        if request.GET.get('q', ''):
            query = request.GET.get('q', '')
            queryset = SearchQuerySet().filter(content=query)
        return queryset

Serializers.py

from oscarapi.serializers import product

class ItemSearchSerializer(serializers.ModelSerializer):
    text = serializers.CharField()
    title = serializers.CharField()
    price = serializers.HyperlinkedIdentityField(view_name='product-price')
    image = product.ProductImageSerializer(many=True, required=False)  

    class Meta():
        model = Product
        fields = ('image', 'price', 'text', 'title')

当我用localhost:8000/api/search/?q=bmw击中端点时，似乎适用于所有其他字段，但不返回图像，这是示例：

[
    {
        "image": null,
        "price": "http://localhost:8000/api/products/2339/price/",
        "text": "2339\nBMW 316 SE Automatic",
        "title": "BMW 316 SE Automatic"
    },
    {
        "image": null,
        "price": "http://localhost:8000/api/products/0029/price/",
        "text": "0029\nBmw 330d\nLoverly car in excellent condition",
        "title": "Bmw 330d"
    }]

另一件事，因为给定产品可能有几张图像，我也想只返回第一张图像，该图像的display_order值为1。
