Is a simple API implementation with Flask and PostgreSQL database.
from flask import Flask
from flask_restful import Api
Have 2 resources: employees and tasks, requested in JSON format
api = Api(app)
api.add_resource(EmployeeResource, "/employees", "/employees/<int:employee_id>")
api.add_resource(TaskResource, "/tasks", "/tasks/<int:task_id>")
Contain the dockerfile and compose.yml to create the image and deploy the api on isolated containers.
You can modify .env file with valid field for DB. Thats is not apropiate for production environment. Take carefully.
FLASK_ENV=development
FLASK_DEBUG=TRUE
FLASK_APP=app.py
DATABASE_URL=postgresql+psycopg2://myuser:mypass@localhost:5432/task_api_db
DATABASE_URL_DOCK=postgresql+psycopg2://myuser:mypass@db:5432/task_api_db
POSTGRES_USER=myuser
POSTGRES_PASS=mypass
POSTGRES_DB=task_api_db
The results are paginated: 5 tasks per page by default:
curl -X GET http://localhost:5000/tasks
If you need, can use other pagination or indicate a specific page:
http://localhost:5000/tasks?page=1&per_page=10
Create employee:
curl -X POST -H "Content-Type: application/json" -d '{"name": "John Doe"}' http://localhost:5000/employees
Create task:
curl -X POST -H "Content-Type: application/json" -d '{"title": "Task 1", "description": "Description of Task 1", "employee_id": 1}' http://localhost:5000/tasks
Update or modify a task:
curl -X PUT -H "Content-Type: application/json" -d '{"title": "Updated Task 1", "description": "Updated description", "employee_id": 1}' http://localhost:5000/tasks/1
Delete task (or employee)
curl -X DELETE http://localhost:5000/tasks/1
