STEPS.md

Step 1: Create a new app:

python manage.py startapp tags

Step 2: Add the app to INSTALLED_APPS in settings.py:

'tags.apps.TagsConfig',

Step 3: Run migrations for the first time:

python manage.py migrate

Step 4: Create a model called Tags with a many-to-many relationship to projects

Step 5: Update the database by creating a new migration and running migrate:

• python manage.py makemigrations tags
• python manage.py migrate

Step 6: Register the model in the admin app by adding to tags/admin.py: admin.site.register(Tags)

from .models import Tags 
admin.site.register(Tags)

Step 7: Restrict tag actions to admins only (add, delete, update)

Step 8: Use Django REST Framework to create a RESTful API:

• Create a urls.py file for URL routes
• Create a serializers.py file to transform data into JSON
• Create a views.py file to apply logic to API endpoints

Step 9: Update the project-level urls.py

Step 10: Create a urls.py file in the tags app with the following code:

```python
from django.urls import path
from .views import TagList, TagDetail

urlpatterns = [
    path('/', TagDetail.as_view()),
    path('', TagList.as_view()),
]
```

Step 11:Create a new serializers.py file in the tags app:

```python
from rest_framework import serializers
from .models import Tags

class TagSerializer(serializers.ModelSerializer):
    class Meta:
        fields = ('id', 'name')
        model = Tags
```

Step 12: Create views in views.py:

```python
from rest_framework import generics
from .models import Tags
from .serializers import TagSerializer

class TagList(generics.ListCreateAPIView):
    queryset = Tags.objects.all()
    serializer_class = TagSerializer

class TagDetail(generics.RetrieveUpdateDestroyAPIView):
    queryset = Tags.objects.all()
    serializer_class = TagSerializer
```

Step 13: Start the development server: python manage.py runserver
