Development Patterns

Key patterns and architectural approaches used in the Django Project Template.

Behavior Mixins

Behavior mixins provide reusable functionality through composition rather than inheritance.

Example usage:

from django.db import models
from apps.common.behaviors.timestampable import Timestampable
from apps.common.behaviors.authorable import Authorable

class BlogPost(Timestampable, Authorable, models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()

This approach ensures:

Clear separation of concerns
Reusable behaviors across models
Easy composition of functionality
Testable behaviors in isolation

HTMX Integration

The project uses HTMX for interactive UI without heavy JavaScript.

Key HTMX patterns:

HTMXView Class: Base class for HTMX-specific views
Partial Templates: Templates designed for HTMX updates
hx-* Attributes: Used directly in templates for HTMX functionality
Targeted Updates: Using hx-target for specific DOM updates

Example HTMX view:

from apps.public.helpers.htmx_view import HTMXView

class TodoListView(HTMXView):
    template_name = "todos/todo_list.html"

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context["todos"] = Todo.objects.filter(user=self.request.user)
        return context

Team-Based Multi-Tenancy

The project implements team-based multi-tenancy for collaborative features.

Implementation includes:

Team Model: Central model for team management
Team Membership: Many-to-many relationship with User model
Team Context: Views maintain team context through request session
Team Permissions: Authorization based on team membership

API Design

The API follows RESTful principles with DRF:

Serializer Hierarchy: Base serializers extended for specific needs
Multiple Authentication: Session and API key authentication
Permissions System: Both object and action-level permissions
Versioning: API versioning through URL or header
