If the category exists it is not added

[scorpio]

hi
Does anyone know how to make it so that if I add a new category and that category exists, a message appears that says the category already exists and does not repeat itself.

Thanks

How do I create a custom form?

I’m just dropping this here so I have something to refer people to when they ask. This is a simple concept app (copyable), that demonstrates the following techniques: Building custom forms for adding and editing list items (as an alternative to the native forms provided by Glide) Preventing duplicate new entries using User Specific Columns and Relations Enforcing mandatory input items The use of visibility conditions and user specific booleans to control user flow There is nothing particula…

Firstly you should have a custom form, follow @Darren_Murphy 's instructions in that thread.

Assuming you store your category name in a “Category Input” variable:

• Create a relation from “Category Input” to the list of existing categories.
• Show an error message when relation is not empty (meaning that’s a duplicate).
• Only allow adding when “Category Input” is not empty and relation is empty.

@ThinhDinh

Cree una relación desde “Entrada de categoría” hasta la lista de categorías existentes.

Thank you but I did not understand what you explained to me

If you want, I can help you live on a zoom meeting.

They will have to write the exact spelling of that category right? including the cases as well.
For example, if the category is “Glide” and they write “glide”, the relation won’t be made.

You can lowercase the input via a Glide plugin, and lowercase the whole existing list as well, then you make the relation through those lowercased text.
