Your Job is to update the src/models.py file with the code needed to replicate the instagram data model.

The project is using the SQLAlchemy Python library to generate the database.

  • What tables do you think instagram might have on its database: E.g: Post, User, etc.?
  • What properties should go inside the user? or inside the Post table?
  • Please add at least 4 models with all of its properties.
  • Degenerate the diagram.png file at the end by running $ python3 models.py on the console.
