Sorry for reopening this issue again...
Replying to [comment:6 David Sanders]:
>> If you want to manually override model form fields you must be sure to
use the correct form field type. In the case of an IntegerField with
choices you must use a ​TypedChoiceField A model form will use these
automatically for an IntegerField by default.
Thanks for the suggestion which I checked on the small test project
mentioned above.
So I've changed the form field type from ChoiceField to TypedCoiceField.
{{{
eAsset=forms.TypedChoiceField(choices=sampleModel.eAssets.choices)
}}}
This change, however, did nothing to the original problem: The
form.has_changed() flag is alway True
regardless of changing or not changing any field in the form.
In the next step I completely removed said line and therefore relied on
the
form field automatically generated - voila, no problem.
Seemingly the ChoiceField/TypedChoiceField methods convert the outgoing
and incoming choice values which confuses the form.has_changed()
detection.
