28653	Missing ForeignKey.on_delete argument in docs	Stefan Schneider	Stefan Schneider	"There's a second required argument needed for `Foreign Key` fields: `on_delete`
. Since 1.11 not providing the argument gives an `Deprecation Warning` but since 2.0 it's required and gives an error if not provieded

In the documentation for [https://docs.djangoproject.com/en/dev/topics/db/queries/ Making Queries] the example doesn't provide the `on_delete` argument.

{{{

    blog = models.ForeignKey(Blog)

should be:
{{{
class Entry(models.Model):
    blog = models.ForeignKey(Blog, on_delete='CASCADING')
}}}"	Bug	closed	Documentation	dev	Normal	fixed			Ready for checkin	1	0	0	0	0	0
