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?

Was it helpful?

Solution

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.

OTHER TIPS

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