I was looking at your link, and the controller has been moved to /admin: discourse/app/assets/javascripts/admin/addon/controllers/edit-category/tabs.js at main · discourse/discourse · GitHub
I’m not sure why it doesn’t trigger. Maybe @observes
doesn’t work well in modifyClass
?
As an alternative, what do you think of:
@action
saveCategory(data) {
const oldParentId = this.model.parent_category_id;
super.saveCategory(data);
const newParentId = this.model.parent_category_id;
if (oldParentId !== newParentId) {
console.log("Apply some logic here when parent category changes");
}
}
