DB

• Use the provided SQLite database (db.sqlite3) for development.
• Campaigns contain Ad sets; Ad sets contain Creatives.

Questions ( 2 mandatory + 1 optional )

Mandatory Questions:

1. Nested Data API Implementation:

• Update /api/data/campaigns/ which should return a list of campaigns with all nested Adsets & Creatives.
• Update /api/data/adsets/ to return a list of adsets with all nested Creatives.

2. Prevent spaming API (Rate limit)

• Implement rate limiting based on IP address for the above endpoints.
• Limit each IP to a maximum of 10 requests per minute to the endpoints.
• Exceeding the limit should return a 429 status code with an appropriate warning message.

Optional Question:

1. (Optional) Base Authentication Change:

• Change the base authentication field from username to user_id on the base user model.

Note

• Multiple solutions may be valid.
• Share your refactoring ideas.
  • nesting api data by modify serializers.py: referencing related_names in each models
  • prevent spaming by add DEFAULT_THROTTLE_CLASSES and DEFAULT_THROTTLE_RATES to settings.py
  • target of throtle for only user because each views only allowed authenticated user to access
  • set NUM_PROXIES to not None for enable checking xff
  • create a utils folder to store custom exception handler and create custome message for HTTP_429
  • add path to new exception hanler to DRF EXCEPTION_HANDLER
• Suggest performance optimization methods: add global pagination for exception handling
