These are the errors I'm getting with my code.
If you need me to attach my code just tell me which files I need to attach. Thanks

SyntaxError: invalid syntax

Python Web Development Techdegree Graduate 21,137 Pointsyou are missing a closing parentheses from index, just above the initialise function.

Treehouse Moderator 68,389 PointsThere is a closing paren missing:
class Meta:
database = DATABASE
indexes = (
(('from_user', 'to_user'), True,
)

Python Web Development Techdegree Graduate 21,137 Pointshello, going to need to see the models.py code to help more but...
check your indentation in and around the def initialize function, and look carefully at the code block above it, are you missing a closing parentheses for example? or is there a block that expects a statement?
