Flask/Pymongo/Restplus - 使用 update（**data）

Question

Flask==1.1.1 pymongo==3.10.1 flask-restplus==0.13.0

我正在尝试将JSON放到URL并使用，但我遇到了一个问题。在 routes.py 我有一个简单的API设置...update()

@api.route('/api/content/<idx>')

class UpdateContent(Resource):

    def put(self,idx):

        data = api.payload

        Content.objects(content_id=idx).update(**data)

        return jsonify(Content.objects(content_id=idx))

使用Postman I are PUTting to /api/content/2

  {

    "content_id": 2,

    "title": "Test 2",

    "description": "Test 2"

  }

我收到这个...

您遇到的问题可能是由于对象中不存在一些其他键作为字段引起的。data使用字典解包时，请确保要解压缩到参数的所有键确实位于要更新的 MongoDB 对象中。
