Conceptually, an interface element of my application can either be
click through (i.e. requires user interaction) or auto-cycle (no user
interaction). So its boolean. But i picked the wrong one when I
originally designed the model and now we have existing data and I
don't want to change it.
So I have a database field
class MyModel(Model):
click_through = models.BooleanField(
. . . )
And a modelform:
class MyForm(ModelForm):
class Meta:
model = MyModel
fields = ('name', 'click_through')
However, come interface tweaking time (now), we decided we want to
display a page with a check box "Auto Cycle?" instead of "click-
through", so I basically need to invert the actual value with respect
to this interface .
What is the easiest way to implement this?
I realize i could create a custom Field class and override to_python
to invert the value after the Form is submitted, but how about
inverting the value after i initiall load an instance of the value and
before it goes into the form, so that it displays a checked box if
click-through is False and vice-versa? Is there an override similar
to to_python for this, or is there another way of going about it?
Thanks,
Ben
