Task #4 - Database

Reading → Coding → Deploy → Code-review

Reading

  1. MongoDB get started: https://docs.mongodb.com/manual/tutorial/getting-started/
  2. Pymongo: https://api.mongodb.com/python/current/tutorial.html
  3. Flask pymongo: https://flask-pymongo.readthedocs.io/en/latest/

Coding

Preparations

  1. Install Python programming language v3.8.2: https://www.python.org/downloads/
  2. Install Flask framework with pip: https://docs.python.org/3/installing/index.html#basic-usage
  3. Install PyMongo and Flask PyMongo with pip
  4. Install MongoDB: https://docs.mongodb.com/manual/installation/

Basic part

  1. Create web application, which can authenticate user with password:
    • Listen on localhost:5000
    • Render authentication form on http://localhost:5000/
    • Return static images and files on http://localhost:5000/static/<image_name>
    • Has secret page for authenticated users on http://localhost:5000/cabinet
  2. Valid usernames and passwords should be stored in MongoDB database
  3. You are allowed to use any JS or CSS frameworks
  4. You are allowed to use only Python programming language and Flask framework
  5. You are allowed to use only MongoDB as database

Optimal part

  1. Add registration function to append new users on http://localhost:5000/register/
  2. You can keep usernames/passwords only in MongoDB

Challenging part

(Part for those, who already knows all that stuff)

  1. Implement password change feature
  2. Fill database with 1 thousand, 1 million, 10 million, … users with the help of Faker library
  3. Add index to username and measure how response time is changed depending on the number of users. Results of the research append to the README.md file
  4. You can draw a graph

Deploy

  1. Register on GitHub: https://github.com/
  2. Join our organization: https://github.com/itmo-wad/
  3. You can create new personal repository or use repository for the previous tasks (but don’t remove old files, just append new directories)
  4. Commit and push your sources to GitHub. And don’t forget to describe shortly what have you done in README.md file. Use Markdown format: https://guides.github.com/features/mastering-markdown/
  5. Also save data from MongoDB as dump or as simple JSON file in the repository

Code-review

  1. Communicate in Telegram chat
  2. Help others to complete the assignment
