Because Django 1.7 has a new checks framework, but only for things that would prevent startup or cause known problems.

This is me implementing others, as I need them.

• morechecks.checks.templates_do_not_do_queries - Ensures that any custom context processors do not trigger a query just by being used. They should instead be made lazy, such that the database is hit when the context variable is used.

That's it, so far.

Add morechecks to your INSTALLED_APPS and run:

python manage.py check morechecks
