'debug_toolbar.middleware.DebugToolbarMiddleware', # ... ] # Configure the Debug Toolbar DEBUG_TOOLBAR_PANELS = [ 'debug_toolbar.panels.timer.TimerPanel', 'debug_toolbar.panels.sql.SQLPanel', # Add more panels as needed ] INTERNAL_IPS = [ # Add your IP address(es) for accessing the toolbar '127.0.0.1', ] # Other settings...
Django Rest Framework
To create a simple API using Django Rest Framework, follow these steps:
# serializers.py from rest_framework import serializers from .models import YourModel class YourModelSerializer(serializers.ModelSerializer): class Meta: model = YourModel fields = '__all__' # views.py from rest_framework import viewsets from .serializers import YourModelSerializer from .models import YourModel class YourModelViewSet(viewsets.ModelViewSet): queryset = YourModel.objects.all() serializer_class = YourModelSerializer # urls.py from django.urls import include, path from rest_framework import routers from .views import YourModelViewSet router = routers.DefaultRouter() router.register(r'yourmodels', YourModelViewSet) urlpatterns = [ path('', include(router.urls)), ] # Other URL patterns...
To use Celery for background tasks, Install a message broker (e.g., RabbitMQ or Redis).
# settings.py CELERY_BROKER_URL = 'your-broker-url' CELERY_RESULT_BACKEND = 'your-backend-url' # Other settings...
Create a Celery task:
# tasks.py from celery import shared_task @shared_task def your_task(): # Task logic goes here pass
Use the task in your Django views:
# views.py from .tasks import your_task def your_view(request): # Trigger the task your_task.delay() # Other view logic...
These are just a few examples of how to use these Django packages in your projects. Remember to refer to the official documentation for each package for more detailed information and advanced usage.
