Say I have a TypedMultipleChoiceField and I'm building a custom select
multiple widget in my template.
If I want to check a box based on an initial value (ie. default
checked options), OR check a box based on form data that has been
returned (ie. error state), I would do this:
<input type="checkbox" {% if form.field.value %}checked{% endif %}>
HOWEVER, {{form.field.value}} source documentation (boundfield.py)
states: "Returns the value for this BoundField, using the initial
value if the form is not bound or the data otherwise."
So basically the equivalent of:
return (form.field.data or form.field.initial)
Not really, since data that are falsey may be valid data. So it's not
equvalent to that.
*Wouldn't it be more appropriate and useful for boundfield.value to
return CLEANED data that has gone through to_python()? As in:*
return (form.field.*cleaned_data* or form.field.initial)
No because then you would lose non-cleaned data in case of errors.
Also there is no guarantee that cleaned up data is valid when re-evaluated.
