Django REST FRAMEWORK Tutorial 1 -- quickstart アプリの API 環境をdocker-compose で 立ち上げる

Posted on January 10, 2022
前回の記事で 環境構築は完了した
8002 で動いている
startapp で project の中で quickstart アプリを作る
https://www.django-rest-framework.org/tutorial/quickstart/#project-setup
quickstart のページを見る
rest4/rest4/ のプロジェクトの中には作れず
rest4/quickstart/ という構成になる。しかし問題はない。
docker-compose run web django-admin startapp quickstart
Starting rest4_db_1 ... done
Creating rest4_web_run ... done
django-admin startapp quickstart で quickstart という名前のアプリができる。
======
migrate する
docker-compose run web python manage.py migrate
Creating rest4_web_run ... done
Operations to perform:
Apply all migrations: admin, auth, contenttypes, sessions
Running migrations:
No migrations to apply.
DB の初期化完了。
=====
create super user でスーパーユーザーを作る
dc run web \
python manage.py createsuperuser \
--email admin@example.com --username admin
Creating rest4_web_run ... done
Password:
Password (again):
Superuser created successfully.
dc は docker-compose のエイリアス。
=====
シリアライザ、ビュー、URL を作る
serializers.py
from django.contrib.auth.models import User, Group
from rest_framework import serializers
class UserSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = User
fields = ['url', 'username', 'email', 'groups']
class GroupSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = Group
fields = ['url', 'name']
ここはチュートリアル通り
============
views.py
from django.contrib.auth.models import User, Group
from rest_framework import viewsets
from rest_framework import permissions
from quickstart.serializers import UserSerializer, GroupSerializer
class UserViewSet(viewsets.ModelViewSet):
"""
API endpoint that allows users to be viewed or edited.
"""
queryset = User.objects.all().order_by('-date_joined')
serializer_class = UserSerializer
permission_classes = [permissions.IsAuthenticated]
class GroupViewSet(viewsets.ModelViewSet):
"""
API endpoint that allows groups to be viewed or edited.
"""
queryset = Group.objects.all()
serializer_class = GroupSerializer
permission_classes = [permissions.IsAuthenticated]
チュートリアルのサンプルでは
from tutorial.quickstart.serializers
になっているが、これだと lint に間違っていると指摘されたので
from quickstart.serializers
にする
==========
urls.py
from django.urls import include, path
from rest_framework import routers
from quickstart import views
router = routers.DefaultRouter()
router.register(r'users', views.UserViewSet)
router.register(r'groups', views.GroupViewSet)
# Wire up our API using automatic URL routing.
# Additionally, we include login URLs for the browsable API.
urlpatterns = [
path('', include(router.urls)),
path('api-auth/', include('rest_framework.urls', namespace='rest_framework'))
]
同様に
=====
まとめ
これで compose で動かせる
