Change other fields value during validation with Formalchemy?

Question

Writing custom validators for Formalchemy is simple. During the validation of SOMEFIELD I can access another fields value using field.parent.SOMEOTHERFIELD.value.

Is it possible to change SOMEOTHERFIELD's value during the validation of SOMEFIELD? Or should I separate changing related field values from the validation process altogether?

gawel's answer was a step but did not solve my problem (see comment under his answer). I changed the value of field.parent.model.SOMEOTHERFIELD but the change was not committed to the db with session.commit().

After trying out many things I found out that you must use fieldset.sync() before field.parent.model.SOMEOTHERFIELD = value. Only then the change is committed.

You can use field.parent.model.SOMEOTHERFIELD = value

This changes the value of field.parent.model.SOMEOTHERFIELD but the change is not committed to the db if I do `session.commit()`... How do I commit the change to the DB? – boadescriptor Mar 29 '12 at 17:34
