ember.js - Many to Many relationship in emberfire -

i wondering wether possible create many many relationship in emberfire. i've got following models:

//employee name: ds.attr('string'), position: ds.attr('string'), accessoryposition: ds.attr('string'), education: ds.attr('string'), experience: ds.attr('string'), imgurl: ds.attr('string'), teachingin: ds.attr('string'), subjects: ds.hasmany('subject', {async: true})  //subject name: ds.attr('string'), coursedescriptionurl: ds.attr('string'), description: ds.attr('string'), examdescriptionurl: ds.attr('string'), imgurl: ds.attr('string'), sportssubject: ds.attr('boolean'), outdoorsubject: ds.attr('boolean'), commonsubject: ds.attr('boolean'), teachers: ds.hasmany('employee', {async : true}) 

and in employee controller:

update(subjects) {       this.get('model.employee').set('subjects',subjects);       this.get('model.employee').save();      } 

but adds /employees endpoint. there anyway make relationship mutual speak?

you have manually add employ subjects. way like:

update(subjects) {    this.get('model.employee').set('subjects', subjects);    this.get('model.employee').save();     subjects.foreach(subject => {      subject.get('teachers').addobject(subject);    });    subjects.invoke('save'); } 

array#pushobject adds subject if it's not in array, , array#invoke calls save method on every element of array.

hope helpful.
