调用现有端点时出现方法不允许错误

Question

我收到此错误：

Method Not Allowed: /api/v1/auth/users/student/submission/
"POST /api/v1/auth/users/student/submission/ HTTP/1.1" 405 41

当访问我的 Django 应用程序 modelviewset 之一的端点时（提交）。

以下是设置；

1. 浏览量

   class SubmissionViewSet(viewsets.ModelViewSet):
       serializer_class = SubmissionSerializer
       queryset = Submission.objects.all().order_by("-created_at")
       permission_classes = [IsAuthenticated]
   
   def perform_create(self, serializer):
       serializer.save(student=self.request.user)
   

2. 网址

    router = routers.DefaultRouter()
    router.register("admin/courses", views.AdminCourseViewSet)
    router.register("student/courses", views.StudentCourseViewSet)
    router.register("student/submission", views.SubmissionViewSet)
   
    urlpatterns = [
      path("users/", include(router.urls)),
    ]
   

3. 序列化器

    class SubmissionSerializer(serializers.ModelSerializer):
    project = serializers.UUIDField()
    course = serializers.SerializerMethodField()
    date_submitted = serializers.SerializerMethodField()
   
    class Meta:
        model = Submission
        fields = [
          "id",
          "project",
          "course",
          "submission_link",
          "status",
          "date_submitted",
          "student_comments",
          "mentor_comments",
         ]
         read_only_fields = ["id","course", "status", "date_submitted"]
   
    def get_course(self, instance):
        return instance.project.course.title
   
    def get_date_submitted(self, instance):
        return instance.date_submitted.strftime("%b %d, %Y")
   

4. 型号

    class Submission(TimeStampedUUIDModel):
        class STATUS(models.TextChoices):
        """
         Choices for the project
        """
   
        REVIEWED = "Reviewed", _("Reviewed")
        PENDING = "Pending", _("Pending")
        NOT_SUBMITTED = "Not_Submitted", _("Not_Submitted")
   
        student = models.ForeignKey(User, on_delete=models.CASCADE)
        project = models.ForeignKey(Project, on_delete=models.CASCADE)
        submission_link = models.URLField()
        status = models.CharField(
            verbose_name=_("Project Review Status"),
            choices=STATUS.choices,
            default=STATUS.NOT_SUBMITTED,
            max_length=20)
        date_submitted = models.DateTimeField(default=timezone.now)
        student_comments = models.TextField(blank=True, null=True, default="")
        mentor_comments = models.TextField(blank=True, null=True, default="")
   
        def __str__(self):
            return f"{self.student.first_name} {self.student.last_name} 
            {self.project.project_title} submission."
   

我想了解我做错了什么，因为我已经用尽了所有让它发挥作用的可能性。 Django 版本：4.1.13 django-rest-framework：3.14.0

Answer 1

尝试从属于提交 URL 的视图中删除“permission_classes”。如果它有效，那么原因是应用程序希望经过身份验证的用户访问端点。
