MInor problem with overriding

[qrilka]

In my model I've created a field:
site = models.ForeignKey(Site, default=Site.objects.get_current)
This field is set to readonly so I want to create Model items only for the current site. It looks like models.py gets loaded before middleware gets invoked so I get incorrect field value.
Currently I've made a workaround with
site = models.ForeignKey(Site, default=lambda:Site.objects.get_current())
Maybe there is a nicer solution for this problem?

I believe this is fixed with the merge of #5 by @dannyclark.
