Is it possible to choose db column name instead of field name for foreign keys in form validation?

If the answer is no - is there some plans to add this possibility in the future?

What do you mean "choose db column name"? Why would this be necessary?

For foreign keys, the method validate() of the object, created by the model_form method, requires field without '_id': region instead of region_id for example.
I would prefer to pass and validate field with the name region_id somehow. As the names like 'region' may cause misunderstanding for a new user of the api: You cannot be sure without reading the documentation, if this field is a link to another object 'region', or just a text field.

I wrote the converter that do the thing that I want, but maybe there is a better way to do the same.

class Converter(ModelConverter):

    def convert(self, model, field, field_args):
        name,field_obj = ModelConverter.convert(self, model, field, field_args)
        return FieldInfo(field.column_name, field_obj)

You know, it's been so long since I worked with wtforms that I'm not sure how to advise you.
