I have three content types: course, section, and lesson. My data flows like this:
course → section → lesson
I would like to automatically add a course to my lesson based on the section the lesson is assigned to, and I’m trying to do it using lifecycle methods, but am having trouble creating a relation. In my api/lessons/models/lessons.js file, I have this:
beforeSave: async (model, attrs, options) => {
// get attached section
const section = model.relations ? model.relations.section : null;
// get sections course
const courseId =
section && section.attributes ? section.attributes.course : null;
// assign to the lesson
if (options.method === "insert" && courseId !== null) {
model.set("course", courseId);
} else if (options.method === "update" && courseId !== null) {
attrs.course = courseId;
}
}
It isn’t working, although I am successfully adding a slug to the lesson (removed the code for clarity) so I know it should be possible. What am I doing wrong?
Thanks!
