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
