Hi guys, I'm new to outsystems and right now I'm building an e-commerce website. I find myself with a difficulty. I'm doing the registration form and at this moment I want to check if the email entered by the user already exists in the database so that I can display an error message. however I don't know how to do it. Can you help me please? Thanks in advance.
Hello Filipe.First, this is a client action so you shouldn't have multiple server actions being called. Use a single one that calls all of those.Second, the "existing users" information is on the database, so you should ask in the server action. For instance, your CreateUser action can have a query GetUsersByUsername and then a check if result is empty.If it is empty, you create. If not, you return "it is duplicated".
Hi Filipe,
