Hi, I have no error message when I wrongly fill a list with spaces / special characters. However the validator works, as I need to respect it to update the record.
db.define_table('parameter', Field('allowed_users', type='list:string'), ) db.parameter.allowed_users.requires = IS_LIST_OF(IS_ALPHANUMERIC()) # I first inserted a row with the default DB administration tool. But no error message also there. form = crud.update(db.parameter, 1, deletable=False) I did try quite everything already : - Redefining error_message at the IS_ALPHANUMERIC level or at the IS_LISTOF. - defining the validator at the table level - Removing the "IS_LIST_OF".. But no success, it 's validating, but no error message displayed. This then becomes quite unusable.
