Hi all,
I've always programmed in traditional web. Now im making a application in reactive but i cant get some simple things to work.
I have a form where i insert names of all kinds of studies. But i want to check that they dont save a name that already exists.
Normally in traditional in the save action i got my aggregate from my preparation and in a if statement i compare it with the value inserted in the form. The form value is in widgets and then the selected form and select the name in the record.
But this doesnt seem the case in reactive. I dont see the form record.
Its probably something very simple but i cant seem to find it.
Thanks in advance!
Kind regards,
Faissal
Hello @Faissal Berrhout ,
To prevent duplicates in your entity, you can define an entity index on the attribute that should maintain uniqueness.
Here is a guide for that: https://success.outsystems.com/documentation/11/building_apps/data_management/data_modeling/create_an_entity_index/
Aah thank you, so i should work more with this in reactive!
