I've been investigating the use of the DAL feature "detect_record_change=True". Apparently it was conceived as a way of detecting when the record in the database has changed since the form was originally built and populated. My need is for a way to detect when the USER has changed fields in the record between the time it was built and some other event, such as when the user tries to navigate away from the form without pressing the "submit" button.
It seems to me the idea is quite similar -- I want to serialize the data in the form and then compare that hash to the same form later. Only instead of comparing the data in the database to the hash I want to compare the form's version of the data again. Has anyone already done this? Is there a better way to detect when a form has actually been changed instead of just viewed? -- Joe B. --
