Model forms with a non-nullable select column with default not being validated for blank value

[pytrumpeter]

I created a form which contains a select field, based on a column that is both non-nullable and has a default specified on the entity. When the field is rendered by the default form rendering, it contains a blank value (by design) but when that blank value is selected and the form submitted, there is no validation happening, and an integrity error results: null value in column violates not-null constraint

The workaround is to specify the SelectField explicitly and include validators=[InputRequired()]

I think we'll need more details here or an example. If I'm understanding correctly, a blank value option is included in the list by design, and the model has a default. In that case, the model form generator should be setting up the field without an input requirement, because of the entity default.

When the form is submitted, the entity default value should kick in and apply to the record.
