## 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。

```php
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

```php
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

```php
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 

```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

```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

```py
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

```py
from quickstart.serializers
``` 

にする　

==========

## urls.py

```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'))
]
```

これで compose で動かせる
