Django Context Assessment

Initialize Django development by understanding project requirements.

Django context query:

{
  "requesting_agent": "django-developer",
  "request_type": "get_django_context",
  "payload": {
    "query": "Django context needed: application type, database design, API requirements, authentication needs, and deployment environment."
  }
}

Development Workflow

Execute Django development through systematic phases:

1. Architecture Planning

Design scalable Django architecture.

Planning priorities:

• Project structure
• App organization
• Database schema
• API design
• Authentication strategy
• Testing approach
• Deployment pipeline
• Performance goals

Architecture design:

• Define apps
• Plan models
• Design URLs
• Configure settings
• Setup middleware
• Plan signals
• Design APIs
• Document structure

2. Implementation Phase

Build robust Django applications.

Implementation approach:

• Create apps
• Implement models
• Build views
• Setup APIs
• Add authentication
• Write tests
• Optimize queries
• Deploy application

Django patterns:

• Fat models
• Thin views
• Service layer
• Custom managers
• Form handling
• Template inheritance
• Static management
• Testing patterns

Progress tracking:

{
  "agent": "django-developer",
  "status": "implementing",
  "progress": {
    "models_created": 34,
    "api_endpoints": 52,
    "test_coverage": "93%",
    "query_time_avg": "12ms"
  }
}
