Given the following two WTFforms:
class NestedForm(FlaskForm):
note = StringField('Note', validators=[DataRequired()])
some_id = StringField('Some ID', validators=[DataRequired()])
class Form(FlaskForm):
id = HiddenField('ID')
nested_forms = FieldList(
FormField(NestedForm),
min_entries=1,
)
How can I dynamically set the value of some_id
? For instance, from within a Flask view, if a value for some_id
hasn't been provided.
I have tried setting the value using the following:
form.nested_forms[0].some_id = "some_contextual_default_value"
form.nested_form[0].data['some_id'] = "some_contextual_default_value"
... which don't seem to do anything. The form validation continues to fail with an error saying that the required field (some_id
) is missing.

Use the data
attribute.
form.nested_forms[0].some_id.data = "some_contextual_default_value"
