AttributeError: 'Settings' object has no attribute 'LEAN_ANALYTICS'

[Bryan]

I followed the instructions to set up django-lean:
http://bitbucket.org/akoha/django-lean/wiki/Home

When I attempted to run:
manage.py test experiments

All the tests failed with:
AttributeError: 'Settings' object has no attribute 'LEAN_ANALYTICS'


Are the installation instructions lacking a step?


Here is the trace route:

Hi Bryan,

That is a bug. The tests should still succeed without that setting.

If you wish to work around it, simply add "LEAN_ANALYTICS = []" to
your settings file.

A better solution is to modify experiments/tests/utils.py {TestCase}
to override __call__ and to use:

with patch(settings, 'LEAN_ANALYTICS', []):
super(TestCase, self).__call__(result)

Or else to extract some of the behaviour from patch (defined in that
file) so that it can be invoked from the _pre_setup and _post_teardown
methods.

I may take a look at it in the next week or two, but if anyone else
likes, feel free to submit a patch.

Cheers,

Erik
