Django REST Framework图片上传 [英] Django REST Framework image upload

问题描述

我有模型产品：

def productFile(instance, filename):
    return '/'.join( ['products', str(instance.id), filename] )

class Product(models.Model):
    ...

    image = models.ImageField(
        upload_to=productFile,
        max_length=254, blank=True, null=True
    )
    ...

然后我有了序列化器：

class ProductSerializer(serializers.ModelSerializer):
    class Meta:
        model = Product
        fields = (
            ...
            'image',
            ...
        )

然后我有意见：

class ProductViewSet(BaseViewSet, viewsets.ModelViewSet):
    queryset = Product.objects.all()
    serializer_class = ProductSerializer

如何使用Postman上传图像？将图片上传到模型的最佳做法是什么？谢谢。

How I can upload image with Postman? What is the best practices to upload image to model? Thank you.

推荐答案

您可以创建用于上传图像的单独端点，就像这样：

you can create separate endpoint for uploading images, it would be like that:

class ProductViewSet(BaseViewSet, viewsets.ModelViewSet):
    queryset = Product.objects.all()
    serializer_class = ProductSerializer

    @detail_route(methods=['post'])
    def upload_docs(request):
        try:
            file = request.data['file']
        except KeyError:
            raise ParseError('Request has no resource file attached')
        product = Product.objects.create(image=file, ....)

您可以解决该问题
