Impossible to reproduce example "Using Multiple Databases"

[Max Snow]

Hi.
I tried to reproduce example shown here: http://turbogears.readthedocs.io/en/latest/cookbook/multiple-databases.html#using-multiple-databases-in-turbogears
I did steps word to word.
After everything done I execute "gearbox setup-app" and the result is:
----
Traceback (most recent call last):
  File "/home/tg2env/site-packages/gearbox/main.py", line 167, in _run_subcommand
    return cmd.run(parsed_args)
  File "/home/tg2env/site-packages/gearbox/command.py", line 31, in run
    self.take_action(parsed_args)
  File "/home/tg2env/site-packages/gearbox/commands/setup_app.py", line 53, in take_action
    self._setup_config(dist, config_file, section, {}, verbosity=self.app.options.verbose_level)

    self._call_setup_app(mod.setup_app, filename, section, vars)

    self._setup_sqlalchemy(conf)
  File "/home/tg2env/site-packages/tg/configuration/app_config.py", line 783, in _setup_sqlalchemy
    engine = engine_from_config(conf, 'sqlalchemy.')
  File "/home/tg2env/site-packages/sqlalchemy/engine/__init__.py", line 427, in engine_from_config
    url = options.pop('url')
KeyError: 'url'
----
I need 2 databases to split auth and common stuff (to prevent access to users' password hashes).

Some things I did on my own (I'm not sure I was correct):

1) Inside 'myapp/config/app_cfg.py' I used ...
----
class MultiDBAppConfig(AppConfig):
    def _setup_sqlalchemy(self, conf):
----
... instead of ...
----
class MultiDBAppConfig(AppConfig):
    def setup_sqlalchemy(self):
----
2) I made changes inside 'myapp/websetup/schema.py => def setup_schema' instead of 'myapp/websetup.py => def setup_app'

If I did something wrong, please let me know.
If I did everything right, could You please correct this part of documentation? Or maybe I read instructions from wrong source?

Best Regards,
Maxim.

The documentation in that paragraph it's in "rough" state and depends heavily on TG internals, so it's something that can break easily on any new release and it's allowed "at your own risk". I promise I'll update that paragraph to make it work with TG2.3 during the weekend so you can check that your changes match with the required ones.

The development branch of documentation should cover all the required changes for multiple databases support: http://turbogears.readthedocs.io/en/development/cookbook/multiple-databases.html#using-multiple-databases-in-turbogears

New documentation contains more than I expected.
Thank You very much!
