Python Django REST:&x27；请求'；对象没有属性'；字段名称'；

我正在尝试创建一个职位申请，以便将一份工作申请添加到申请者列表中。这是由

POST/task worker/

但是，我得到了一个错误：

“请求”对象没有“任务”属性

型号.py

class Task_worker(models.Model):
    worker = models.ForeignKey(Worker)
    task = models.ForeignKey(Task)

        fields = ('id', 'task', 'worker', 'created', )

    def create(self, validated_data):
        validated_data['task_id'] = self.context['request'].task
        return super(TaskWorkerSerializer, self).create(validated_data)

class TaskWorker(generics.ListCreateAPIView):
    serializer_class = TaskWorkerSerializer

        return queryset

    def perform_create(self, serializer):
        worker = Worker.objects.get(user=self.request.user)
        task = Task.objects.get(pk=self.kwargs.get('task_id', ''))
        serializer.save(task=task, worker=worker)
        #ALSO TRIED

视图.py

class Task_worker(models.Model):
    worker = models.ForeignKey(Worker)
    task = models.ForeignKey(Task)

    class Meta:
        unique_together = ('worker', 'task')

class Task(models.Model):
    ...

class Worker(models.Model):
    ...

class TaskWorkerSerializer(serializers.ModelSerializer):
    task = serializers.ReadOnlyField(source='task.id')
    worker = serializers.ReadOnlyField(source='worker.id')

    class Meta:
        model = Task_worker
        fields = ('id', 'task', 'worker', 'created', )

    def create(self, validated_data):
        validated_data['task_id'] = self.context['request'].task
        return super(TaskWorkerSerializer, self).create(validated_data)

class TaskWorker(generics.ListCreateAPIView):
    serializer_class = TaskWorkerSerializer

    def get_queryset(self):
        task_id = self.kwargs.get('task_id', '')
        queryset = Task_worker.objects.filter(task__user=self.request.user, task_id=task_id).distinct()
        return queryset

    def perform_create(self, serializer):
        worker = Worker.objects.get(user=self.request.user)
        task = Task.objects.get(pk=self.kwargs.get('task_id', ''))
        serializer.save(task=task, worker=worker)
        #ALSO TRIED
        #serializer.save(task_id=self.kwargs.get('task_id', ''), worker=worker)

url(r'^task-worker/(?P<task_id>[0-9]+)/$', views.TaskWorker.as_view()),

即使在

perform\u create（）

中没有明确的

task

，我仍然会得到相同的错误，即请求没有任务属性

url.py

class Task_worker(models.Model):
    worker = models.ForeignKey(Worker)
    task = models.ForeignKey(Task)

    class Meta:
        unique_together = ('worker', 'task')

class Task(models.Model):
    ...

class Worker(models.Model):
    ...

class TaskWorkerSerializer(serializers.ModelSerializer):
    task = serializers.ReadOnlyField(source='task.id')
    worker = serializers.ReadOnlyField(source='worker.id')

    class Meta:
        model = Task_worker
        fields = ('id', 'task', 'worker', 'created', )

    def create(self, validated_data):
        validated_data['task_id'] = self.context['request'].task
        return super(TaskWorkerSerializer, self).create(validated_data)

class TaskWorker(generics.ListCreateAPIView):
    serializer_class = TaskWorkerSerializer

    def get_queryset(self):
        task_id = self.kwargs.get('task_id', '')
        queryset = Task_worker.objects.filter(task__user=self.request.user, task_id=task_id).distinct()
        return queryset

    def perform_create(self, serializer):
        worker = Worker.objects.get(user=self.request.user)
        task = Task.objects.get(pk=self.kwargs.get('task_id', ''))
        serializer.save(task=task, worker=worker)
        #ALSO TRIED
        #serializer.save(task_id=self.kwargs.get('task_id', ''), worker=worker)

url(r'^task-worker/(?P<task_id>[0-9]+)/$', views.TaskWorker.as_view()),

在序列化程序的创建方法中，不需要这一行

validated_data['task\u id']=self.context['request'].task

。任务将自动添加

此外，如果您有此功能，则不需要

validated_data['worker']=self.context['request'].worker

从文档中：

调用.create（）或.update（）时，任何其他关键字参数都将包含在已验证的_数据参数中

您想向Task_worker模型添加条目吗？@VikasDamodar是的，但是因为它是一个多对多（Task_worker）的槽表，所以我需要指定Task_idIt，如果发生错误，它不清楚。请发布完整的回溯。@DanielRoseman AddedI认为serializers.py中存在问题，您是否也可以添加该问题？
