Nowadays, we have too many social media accounts.

Using this tool, a user can follow all updates of another user with just this single page.

• A user can track many users, and a user can be tracked by many users. (Many-to-many relationships + Association object, we save a following_since variable on purpose)
• The user has multiple accounts, e.g., Twitter, Facebook, ... (One-to-many relationships)
• We use inheritance, as the accounts can differ on multiple aspects (TwitterAccount, FacebookAccount).
• A strategy pattern will be used to get the appropriate content (Facebook, Twitter) TODO
• However, testing with genuine data can only happen with an internet connection, thus we'll use mock objects and unit tests. TODO
• An observer pattern will be used to notify the user. TODO
• A HowTo on generating Sphinx docs. TODO

Use virtualenv so we can work independently from other projects. For instance:

virtualenv -p /usr/local/bin/python3 venv
source venv/bin/activate

The following command should install all the dependencies this project requires.

pip -r install requirements.txt

Creating the database is not hard:

(venv) > python
>>> from app import db
>>> db.create_all()

The scripts/helper.py script might also be helpful

Notes:

• Admin page can only be accessed by admins obviously.
• If you delete your own account while being logged in, you will get logged out in a fatal way.

• An appropriate .gitignore file (for Python, Sphinx, however, no LaTeX)
• Find some fixed version for the packages
• Unit-testing
• Integration-testing via Mockups (for Twitter, ...)
