压缩并下载Django Rest Framework生成的json文件

Question

Let's suppose that my django rest framework app is returning this json for this url (where 4 is the pk of a model): http:mydomain.com/model_number/4/?format=json

[
    {
        "id": 96, 
        "title": "title 1",
        "picture": "static/uploads/pic1.jpg"
    },
    {
        "id": 97, 
        "title": "title 2",
        "picture": "static/uploads/pic2.jpg"
    },
    {
        "id": 98, 
        "title": "title 3",
        "picture": "static/uploads/pic3.jpg"
    }
]

I want to create and download a zip with a json file which has the content explained above (generated by django rest framework), and a folder with pic1 , pic2 and pic3 .

I'm able to download a zip with a folder containing those pictures, but I don't know how to include the json file.

I don't know if it is related with parsers :

Any help would be appreciated

Answer 1

Just construct an instance of your serializer with model instance as argument. Serializer object has property data .

class YourModel(models.Model):
    ...

class YourModelSerializer(serializers.ModelSerializer):
    ...

your_json = YourModelSerializer(YourModel.objects.get(pk=5)).data

You also can use queryset with flag many=True :

your_json = YourModelSerializer(YourModel.objects.all(), many=True).data
