Grit One SDK¶
Overview¶
Grit One SDK is a high-level web framework that enables rapid development of secure and maintainable web applications. It provides a comprehensive set of tools and abstractions for common web development tasks.
Key Features¶
- Rapid Development: Pre-built components and conventions reduce boilerplate code
- Security First: Built-in protection against OWASP top vulnerabilities
- ORM: Object-relational mapping for database operations without raw SQL
- Admin Interface: Auto-generated administration panel for content management
- Authentication System: Complete user management with sessions and permissions
- Scalable Architecture: Supports both monolithic and microservice patterns
- REST API Support: Built-in serialization and API development tools
- Middleware System: Extensible request/response processing pipeline
Installation¶
# Install Grit One SDK
git clone PROVIDED_URL
# Navigate to project directory
cd myproject
# Run development server
python manage.py runserver
Quick Start¶
Create a simple web application:
# views.py
class HomeView(View):
def get(self, request):
return render(request, 'home.html', {'title': 'Welcome'})
# urls.py
from .views import HomeView
urlpatterns = [
path('', HomeView.as_view(), name='home'),
]
Architecture¶
Core Components¶
- Request/Response Cycle: HTTP request processing through middleware layers
- URL Dispatcher: Maps URLs to view functions or classes
- Template Engine: Server-side rendering with template inheritance
- Database Layer: Abstract database operations through models
- Static Files: Efficient handling of CSS, JavaScript, and media files

Core Modules¶
Authentication & Authorization¶
@login_required
def protected_view(request):
# Only authenticated users can access
return HttpResponse(f"Welcome, {request.user.username}")
Database Models¶
class Product(models.Model):
name = models.CharField(max_length=200)
price = models.DecimalField(max_digits=10, decimal_places=2)
created_at = models.DateTimeField(auto_now_add=True)
class Meta:
ordering = ['-created_at']
Admin Interface¶
from .models import Product
@admin.register(Product)
class ProductAdmin(admin.ModelAdmin):
list_display = ['name', 'price', 'created_at']
search_fields = ['name']
list_filter = ['created_at']
Security Features¶
Built-in Protections¶
- SQL Injection: Parameterized queries prevent injection attacks
- XSS Prevention: Automatic HTML escaping in templates
- CSRF Protection: Token-based protection for state-changing operations
- Clickjacking: X-Frame-Options header support
- HTTPS Support: Secure cookies and HSTS enforcement
- Password Security: PBKDF2 hashing with SHA256
Example: Building a REST API¶
# serializers.py
from .models import Product
class ProductSerializer(serializers.ModelSerializer):
class Meta:
model = Product
fields = ['id', 'name', 'price', 'created_at']
# views.py
from .models import Product
from .serializers import ProductSerializer
class ProductViewSet(viewsets.ModelViewSet):
queryset = Product.objects.all()
serializer_class = ProductSerializer
# urls.py
from .views import ProductViewSet
router = DefaultRouter()
router.register('products', ProductViewSet)
urlpatterns = router.urls
