Coding Task: Django Application with External API Integration, PostgreSQL, and Celery

Task Description:

Create a Django application that integrates with a public API, retrieves data, and stores it in a PostgreSQL database. The application should expose endpoints to fetch the stored data and perform basic CRUD operations.

Requirements:

1. External API Integration:

• Use a public API (e.g., OpenWeatherMap API) to fetch weather data for a given city.
• Store the fetched data in a PostgreSQL database.

Celery

Celery is a distributed task queue that handles real-time processing with a focus on operations requiring immediate execution.

Pros:

• Maturity: Celery has been around for a long time and is a well-established tool with a large community. It is used in many production environments, which attests to its reliability and robustness.
• Flexibility: It supports multiple message brokers like RabbitMQ, Redis, and Amazon SQS, providing flexibility in choosing the right tool for message passing.
• Scalability: It can scale out to handle a large number of tasks very efficiently across multiple workers and servers.
• Performance: Optimized for high-throughput and real-time task processing, making it ideal for applications that require immediate task processing.
