Field type "Computed"

Arthur Fontaine

It would be great to be able to add a field that returns a value computed from the other fields without having to create a custom controller and a custom route.

Before we get this, you can use life cycles.
Add a lifecycles.js in your class folder with code like this:
module.exports = {
beforeCreate(event) {
grade = event.params.data.grade;
level  = event.params.data.level;
event.params.data.class_name = G${grade} ${level} 
;
},
beforeUpdate(event) {
grade = event.params.data.grade;
level  = event.params.data.level;
event.params.data.class_name = G${grade} ${level} 
;
},
};
