Comment:
> Changing `ChoiceField(...)` to `TypedChoiceField(..., coerce=int)` does
only affect `my_form.cleaned_data["colour"]`, but neither of
`my_form.fields["colour"].choices`,`{{ my_form.fields.colour.choices }}`,
or `my_form["colour"]`, or`{{ my_form.colour.value }}`.
Yes, and that's exactly what you should use, `TypedChoiceField` and
`cleaned_data`.
> Ultimately leads to `{% if colour_id == my_form.colour.value %}` never
being true when the form is bound, even when it should.
That's an incorrect expectation. `BoundField.value()` is the ''raw'' value
of the field. If you're having trouble understanding how Django works,
