event for deleting record of list

usr338

Hi, is there any way to run function (event) in front-end, before delete a record in list?( usually to validate delete operation or execute code to handle side effects ). it is possible in opened form but not directly in list view.
It is possible to do things in delete trigger of tables but using trigger makes every thing more complicated.

This is currently only possible via backend triggers. While triggers can become complicated, it usually the much 'safer' option when handling side effects as they are always executed.

A hypothetical frontend function, running before a delete on a list field, would need to be reimplemented on every list and every form, now and in the future, that could also delete the same record - directly or indirectly via cascading relationships.

Even if we would add these frontend functions in the future, handling data should always be done in the backend. While triggers can become complex, you can learn techniques to vastly simplify your logic and make everything more straightforward.

gabriel Thanks for response. but in trigger we don't know what states (data ) was collected in UI (neither the logic that collect that data). I mean we have to duplicate some logic that exist in front-end to collect same data in trigger.

Yes, the backend has no idea what you are doing on the frontend. And if you have been avoiding the backend it would be effort to switch.

In general though, the backend is the better tool to handle data operations and side effects as it´s much more reliable. The frontend is complex, with many chances to forget to implement business logic or implement it in different ways (or forget to update it everywhere, or have unexpected interactions between frontend elements, ....).

It´s still up to you if you want to hammer the nail with a hammer or a buzzsaw. Both will work, though I prefer the hammer.
