Double data warning

I’m “building” a database on tabidoo but I have a concern. Every time I insert an article I already saved, I don’t get any advise or error popup.

How can I activate one?
Thank you


after saving the form, the data is always written to the database. If you fill in the form incorrectly, you may get a message like Required field, invalid script, etc. If you would still like information after saving correctly, you can choose script doo.toast.success(text, title?);
