将带有多部分/表单数据的 HTML/axios 对象列表发布到 DRF 多部分解析器 [英] Post LIST OF OBJECTS from HTML/axios with multipart/form-data to DRF multipart parser

问题描述

这是我的序列化程序:

class ParentSerializer(serializers.ModelSerializer):
    children = ChildSerializer(many=True)  # reverse FK relation

ParentSerializer 也有一个图像字段，因此请求必须是 multipart/form-data 以在单个请求中同时支持图像和数据.

ParentSerializer also has an image field, so the request has to be multipart/form-data to support both image and data in a single request.

以下代码/测试工作正常:

The following code/test works fine:

test_data = QueryDict('', mutable=True)
dictionary = {
    'name': ['test'],
    'children[0]': [{'key1': 'val1', 'key2': 'val2'}]
}
test_data.update(MultiValueDict(dictionary))

test_serializer = self.get_serializer(data=test_data)
test_serializer.is_valid(raise_exception=True)
test_instance = test_serializer.save()

...因为我正在手动创建 children 列表.

...because I'm manually creating the children list.

问题是我无法通过 axios/HTML 表单做同样的事情.正在发送的数据被转换为字符串.

The problem is I'm not able to do the same through axios/HTML form. The data being sent is converted to string.

我有哪些选择?我想将子对象列表与其他数据一起发送.

What are my options? I want to send list of child objects along with other data.

DRF v3.9 &Django v2.2.

推荐答案

您的字段必须以以下形式命名 children[0]key1, children[0]key2>、children[1]key1、children[1]key2

Your fields must be named in the following form children[0]key1, children[0]key2, children[1]key1, children[1]key2

注意]和键名之间没有点.
