tornado.database Importerror: No module named database
Question: I'm using a fork of Bret Taylor's 'socialcookbook'
(<https://github.com/finiteloop/socialcookbook>) which uses "import
tornado.database" - and it's worked perfectly until yesterday (the 3.01
build?) and now I'm getting an ImportError: no module named database when I
compile on Heroku (using Python).

My **requirements.txt** file is simple:

    
    
    mysql-python
    tornado
    

My **import** statements:

    
    
    import base64
    import datetime
    import functools
    import json
    import hashlib
    import hmac
    import time
    import logging
    import os
    import smtplib #for mandrill email notifications
    import httplib #for custom error handler
    import re
    import string
    import tornado.database
    import tornado.escape
    import tornado.httpclient
    import tornado.ioloop
    import tornado.web
    import urllib
    import urllib2
    import urlparse
    from tornado.options import define, options
    import facebook
    

Any thoughts? I'm having a hard time troubleshooting this one and I can't push
new builds (old builds work fine if I rollback on Heroku, though, oddly..)


Answer: As it turns out, Tornado 3.0 has deprecated tornado.database and replace it
with torndb: <https://github.com/bdarnell/torndb>

So the fix is to simply replace all tornado.database references with torndb
and add torndb to the requirements.txt file.
