无法使用 django rest swagger 运行 Django-rest-framework 应用程序

Question

我用 Django-rest-framework 创建了一个后端 api。这是我的views.py -

from django.shortcuts import render
from rest_framework import viewsets
from rest_framework.response import Response
from rest_framework import generics
from .models import table1, table2
from .serializers import table_1_Serializer, table_2_Serializer
from rest_framework.permissions import IsAuthenticated #new token


class table_1_View(viewsets.ModelViewSet):
    queryset = table1.objects.all()
    serializer_class = table_1_Serializer
    http_method_names = ['get']


class table_2_View(viewsets.ModelViewSet):
    queryset = table2.objects.all()
    serializer_class = table_2_Serializer
    http_method_names = ['get']

这是我的 serialisers.py

from rest_framework import serializers
from .models import table1, table2

class table_1_Serializer(serializers.ModelSerializer):
    class Meta:
        model = TasteCluster
        fields = ('id', 'name', 'dept_id')



class table_2_Serializer(serializers.ModelSerializer):
    class Meta:
        model = TasteCluster
        fields = ('dept_id', 'dept_name', 'dept_strength')

这是我的 urls.py

from django.urls import path, include
from . import views
from rest_framework import routers



router = routers.DefaultRouter()
router.register('table_1', views.table_1_View)
router.register('table_2', views.table_2_View, basename='table_2')


urlpatterns = [
    path('', include(router.urls))
]

这对我来说很好。现在我正在尝试将 Django-Rest-Swagger 集成到我的项目中。

我已经在虚拟环境中安装了 Django-rest-swagger。

我已将其添加到已安装的应用程序中。这是我现在的 settings.py -

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'my_app',
    'rest_framework',
    'rest_framework_swagger',
    #'rest_framework.authtoken',
]

这是我的新 urls.py -

from django.urls import path, include
from . import views
from rest_framework import routers
from rest_framework_swagger.views import get_swagger_view
from rest_framework_swagger.renderers import OpenAPIRenderer, SwaggerUIRenderer

schema_view = get_swagger_view(title='Test API Documentation')



router = routers.DefaultRouter(
     schema_title='Pastebin API',
     schema_renderers=[OpenAPIRenderer, SwaggerUIRenderer]
)
router.register('table_1', views.table_1_View)
router.register('table_2', views.table_2_View, basename='table_2')

urlpatterns = [
    path('', include(router.urls)),
    path('api_documentation', include('rest_framework.urls', namespace='rest_framework'))
]

但是当我这样做时会出错。 当我尝试运行时

python3 manage.py runserver

我收到此错误 -

如何将 swagger 与我现有的 Django-rest-framework 应用程序集成？

Answer 1

change you urls.py for rest framework swagger:-


from rest_framework_swagger.views import get_swagger_view

schema_view = get_swagger_view(title='API')

urlpatterns = [
    path('docs/', schema_view),
]


Then in settings.py file, add the below lines:-

REST_FRAMEWORK = {
    'DEFAULT_SCHEMA_CLASS': 'rest_framework.schemas.coreapi.AutoSchema'
}
