Django-0.96. I've discovered the get_FOO_display() function that I get for
free when I use a "choices=CHOICES" in a model, and I understand how to use
it in a template or in the API. But the problem I'm having is that when I
save something with a choices attribute, editing that object subsequently
shows the item as "---------" (as if it's never been set before).
For example:
ALLOWED=((600.0, 'Area 1'), (1200.0, 'Area 2')
class something(models.Model):
...
area_charge = models.FloatField(max_digits=7, decimal_places=2,
choices=ALLOWED
...
The select box populates with Area 1 and Area 2, and the float gets
populated in the database correctly as 600 or 1200 based on the selection.
But after saving, say, 600.0 as the area_charge, editing that item again
yields the same select box as initial entry, but the Area 1 entry is no
longer selected; the row of hyphens is showing. Saving in this condition
elicits an error message because the entry is required.
I'd like to see the 600.0 stored in the database cause Area 1 to be selected
when the item is opened for editing. This seems exactly like what
get_area_charge_display() should do, but I can't figure out where it goes in
the model/admin classes.
Thanks for any light you can shed on this.
Cheers!
