Avito Tech Internship Backend Test Assignment

The goal is to develop a chat server that provides an HTTP API for working with chats and user messages.

Source: https://solvit.space/test-tasks/1

Development:

• Core entities:
  • User.
  • Message.
  • Chat.
• • Set up data storage.
• Main API methods:
  • Add a new user.

    curl -X POST "http://127.0.0.1:9000/users/create-user" -H "Content-Type: application/json" -d '{"username": "test"}'

  • Create a new chat between users.

    curl -X POST "http://127.0.0.1:9000/chats/create-chat" -H "Content-Type: application/json" -d '{"name": "test", "users": [1, 2, 3]}'

  • Get the list of chats for a specific user.

    curl -X GET "http://127.0.0.1:9000/chats/get-chats/user/1"

  • Send a message to a chat on behalf of a user.

    curl -X POST "http://127.0.0.1:9000/messages/create-message" -H "Content-Type: application/json" -d '{"chat_id": 1, "author_id": 1, "text": "test"}'

  • Get the list of messages in a specific chat.

    curl -X GET "http://127.0.0.1:9000/messages/get-messages/chat/1"

• • Provide instructions for running the application.

Bonus:

• • Use containerization with the ability to run the project using docker-compose up.

    sudo systemctl restart docker
    docker ps -a
    
    docker compose up --build
    docker compose down -v       # optional

• • Add test coverage.

Run:

Project uses SQLAlchemy, Pydantic and PostgreSQL.
