Python，Django無法運行我的服務器

Question

我嘗試使用Django創建RESTful API。 您能幫我解決這個問題嗎，我不知道為什么會有這個錯誤。

我做了遷移，所以我用了

python manage.py makemigrations

和

python manage.py遷移

我創建了超級用戶

python manage.py createsuperuser

如果您需要更多代碼，請回答。 謝謝

楷模

from django.db import models

class employees(models.Model):
    firstname=models.CharField(max_length=10)
    lastname=models.CharField(max_length=10)
    emp_id=models.IntegerField()

    def __str__(self):
        return self.firstname

串行

from rest_framework import serializers
from rest_framework import employees

class employeesSerializer(serializers.ModelSerializer):

    class Meta:
        model= employees
        #fields=('firstname','lastname')
        fields= '__all__'

VIEWS

from django.shortcuts import render

from django.http import HttpResponse
from django.shortcuts import get_object_or_404
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework import status
from . models import employees
from . serializers import employeesSerializer


class employeeList(APIView):

    def get(self, request):
        employees1= employees.objects.all()
        serializer=employeesSerializer(employees1, many=True)
        return Response(serializer.data)

    def post(self):
        pass

URLS

from django.contrib import admin
from django.urls import path
from rest_framework.urlpatterns import format_suffix_patterns
from webapp import views




urlpatterns = [
    path('admin/', admin.site.urls),
    url('employess/',views.employeeList.as_view()),
]

您的輸入錯誤。 from rest_framework import employees serializers.py 。 它應該是

from .models import employees
