如何在Django中向request.data添加新的键值

Question

我想知道如何向请求添加新值。数据

这是我的请求。数据，结构：

[{'fname': 'john', 'lname': 'Doe'}]

例如，如何添加年龄键

这是我的全部代码：

def create(self, request):
    formSerializer = self.serializer_class(data = request.data)
 #### look Down
    request.data['master'] = self.request.user.id
 #######
    if formSerializer.is_valid():
        formSerializer.save()
        objectSerializer = TeamSerializer(Team.objects.all(), many=True)
        return Response(objectSerializer.data, status = 
             status.HTTP_201_CREATED)
    return Response(formSerializer.errors, status.HTTP_400_BAD_REQUEST)

这是我的模型

from django.db import models
from users.models import CustomUser

# Create your models here.
class Team(models.Model):
    master = models.ForeignKey(CustomUser, on_delete=models.CASCADE)
    name = models.CharField(null=False, blank=False, max_length=255)
    comment = models.CharField(null=True, blank=True, max_length=255)

我有两个输入字段（名称+注释），所以我需要主字段，这就是为什么

在这里，您不需要在request.data中添加mater

试试这个：

    def create(self, request):
        formSerializer = self.serializer_class(data = request.data)
        # request.data['master'] = self.request.user.id
        if formSerializer.is_valid():
            formSerializer.save(master = self.request.user)
            objectSerializer = TeamSerializer(Team.objects.all(), many=True)
            return Response(objectSerializer.data, status = 
                 status.HTTP_201_CREATED)
        return Response(formSerializer.errors, status.HTTP_400_BAD_REQUEST)

从序列化程序的字段中删除master 并将其添加到serializer：

    class MYSerializer(serializers.ModelSerializer):
        username = serializers.CharField(source='master.username',read_only=True)
        
        class Meta:
            model = MY_MODEL
            fields = (OTHER_FIELDs,'username')

Source Mean??
