Hello everyone, in my model I have amongst other fields, the :variant_id and :cart_id, I want to validate their presences but in my app the user only needs to set one of them, so I can’t make it validates_presence_of :variant_id, :cart_id.
I am sure there’s a solution for that, please tell me if you know!
Thanks!

You can either write a custom validation method that returns false if both are unset or you could add some :if => {...} code to your validation line so it only validates one field if the other is blank. You'd need that on both validation lines and your error message would be a little confusing suggesting the user needs to pick both.
If it was me, I'd go custom so I could put up a reasonable error message.
