# TRACKER SCHEMA

# Class automatically gets these properties:
#   creation = Date()
#   activity = Date()
#   creator = Link('user')
#   actor = Link('user')

# The "Minimal" template gets only one class, the required "user"
# class. That's it. And even that has the bare minimum of properties.

# Note: roles is a comma-separated string of Role names
user = Class(db, "user", username=String(), password=Password(),
