I need to build a custom form to perform a database operation on a set of
records. I'm using SQLFORM.factory to build the custom form.
Depending on the request vars, the form will change defaults and form
element behaviour (the element can be writable or not, depending on how the
request vars are given)
I have a form field that is a reference to a record in a db table in the
defined model.
writable = some_condition()
form_fields = []
form_fields.append(Field('AllocationScenario',
writable=writable,
default=allocation_version.id,
requires=IS_IN_DB(db,
db.AllocationVersion.id,'%(Name)s'))
)
...
form = SQLFORM.factory(*form_fields)
If the element representing the form var needs to be editable (when
some_condition evaluates True), it is shown as expected as a select
element, with options populated from the references db table.
On the other hand, if I some_condition evaluates False, the element is
shown as the provided default value (i.e. an integer id value), instead of
the corresponding label of the selected option.
Wouldn't it be more appropriate to set the displayed value to the
corresponding label of the select option?
What is the best way to work around this issue?
