Hi All,
Now I'm at ForeignKey funkiness. So I have the Services model which
has a ForeignKey field to the Sermon model. The funny thing is that
if I choose a sermon object when I first create a new service object,
all is well. If, on the other hand, I don't choose one, then it turns
out that I can never choose one. That is to say, I can choose one,
and hit save and when I come back in it's unchosen. Happens every
single time. I've attached the services/models.py and
sermons/models.py if that helps.
Thanks!
Seemant
