Python Flask CRUD Application

A minimal python flask app for inventory management, with some basic functionality:

• Fetch and display items from the MySQL db as an html table
• Add new items to the db (individually) using a form
• Edit existing (individual) items in the db using a form
• Delete (individual)items in the db
• Add a batch of new items from a csv file
• Edit a batch of existing items with new data from a csv file
• Let the user preview and edit the csv data in a table before submission
• Use an admin-defined configuration to decide the attributes of an item, and how to manage the db and data
