It is the only model in any of the Oscar dashboard apps. It causes an
issue with the get_model() call, because the dashboard app labels had
to be renamed for Django 1.7. So in Django < 1.7
get_model('ranges', 'RangeProductFileUpload') would work, wheras in
Django 1.7 it had to be get_model('ranges_dashboard',
'RangeProductFileUpload'). There is other ways of solving the problem,
but given that it is a rarely used model of temporary nature, enforcing
that dashboard apps are models-free seems like the cleanest solution.
This only has to be enforced till support for Django 1.6 is dropped, and
I doubt we'll see the need for a model in a dashboard app till then.
