我对django很陌生。我正在尝试创建一个简单的rest端点，但是我得到了一个404。我肯定我错过了一些场景。models.py

class DisplayItems(models.Model):
    yesNo = models.CharField(max_length=10)
    yogaMessage = models.CharField(max_length=50)
    yogaTimeMessage = models.CharField(max_length=100)

    @classmethod
    def create(cls, yesNo, yogaMessage, yogaTimeMessage):
        displayItems = cls(yesNo=yesNo, yogaMessage=yogaMessage, yogaTimeMessage=yogaTimeMessage)
        return displayItems

serializers.py

from .models import DisplayItems

class DisplayItemsSerializer(serializers.ModelSerializer):
    yesNo = serializers.CharField(max_length=10)
    yogaMessage = serializers.CharField(max_length=50)
    yogaTimeMessage = serializers.CharField(max_length=100)

    class Meta:
        model = DisplayItems
        fields = ('__all__')

urls.py

from .views import DisplayItemsViews
from django.contrib import admin
urlpatterns = [
    path(r'^admin/', admin.site.urls),
    path(r'^zzz/', DisplayItemsViews.as_view()),
]

views.py

from rest_framework.response import Response
from rest_framework import status
from .serializers import DisplayItemsSerializer
from .models import DisplayItems


class DisplayItemsViews(APIView):
    def get(self, request):
        displayItems = DisplayItems.create("YES!", "There's yoga today", "At 2:00 pm Eastern Time")
        serializer = DisplayItemsSerializer(displayItems)
        return Response({"status": "success", "data": serializer.data}, status=status.HTTP_200_OK)

我试图运行的url是http://127.0.0.1:8000/zzz/。

我读过几乎所有相关的堆叠溢出帖子，但似乎无法理解我错过了什么。

有三件事：

1-您在rest_framework的INSTALLED_APPS of settings.py中安装了settings.py吗？

2- path()在您的urls.py中不应该包含r'^部分，这意味着正确的路径是path('admin/', admin.site.urls)和path('zzz/', DisplayItemsViews.as_view())。这是Django建议使用url()而不是path()时的老行为

3-我假设您已经在您的views.py中导入了views.py，如果没有，则需要from rest_framework.views import APIView

编辑:我的工作本地版本。

views.py

from rest_framework.response import Response
from rest_framework import status
from rest_framework.views import APIView

from .serializers import DisplayItemsSerializer
from .models import DisplayItems


class DisplayItemsViews(APIView):
    def get(self, request):
        displayItems = DisplayItems.create("YES!", "There's yoga today", "At 2:00 pm Eastern Time")
        serializer = DisplayItemsSerializer(displayItems)
        return Response({"status": "success", "data": serializer.data}, status=status.HTTP_200_OK)

settings.py

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'base',
    'rest_framework'
]

urls.py

from django.contrib import admin
from django.urls import path

from base.views import DisplayItemsViews

urlpatterns = [
    path('admin/', admin.site.urls),
    path('zzz/', DisplayItemsViews.as_view())

]

models.py

class DisplayItems(models.Model):
    yesNo = models.CharField(max_length=10)
    yogaMessage = models.CharField(max_length=50)
    yogaTimeMessage = models.CharField(max_length=100)

    @classmethod
    def create(cls, yesNo, yogaMessage, yogaTimeMessage):
        displayItems = cls(yesNo=yesNo, yogaMessage=yogaMessage, yogaTimeMessage=yogaTimeMessage)
        return displayItems

serializers.py

from rest_framework import serializers

from .models import DisplayItems

class DisplayItemsSerializer(serializers.ModelSerializer):
    yesNo = serializers.CharField(max_length=10)
    yogaMessage = serializers.CharField(max_length=50)
    yogaTimeMessage = serializers.CharField(max_length=100)

    class Meta:
        model = DisplayItems
        fields = ('__all__')
