Comment (by ishirav):
Yes! Please please please apply this patch. We've seen ridiculous queries
joining 20 or more tables needlessly, and MySQL hanging while trying to
run these queries.
As a temporary workaround, here's a way to override the select_related
depth in the admin queryset:
{{{
class FoobarAdmin(admin.ModelAdmin):
def queryset(self, request):
qs = super(FoobarAdmin, self).queryset(request)
return qs.select_related(depth=1)
}}}
