I\'ve figured out that I can clone an Ember Data record and copy its Attributes, but none of the belongsTo/hasMany relationships are cloned. Can I do t

Here is the simple way to clone your Ember Model with relationships. working fine.

Create a Copyable mixin like,

import Ember from 'ember';

export default Ember.Mixin.create(Ember.Copyable, {

    copy(deepClone) {
      var model = this, attrs = model.toJSON(), class_type = model.constructor;
      var root = Ember.String.decamelize(class_type.toString().split(':')[1]);

      if(deepClone) {
          this.eachRelationship(function(key, relationship){
              if (relationship.kind == 'belongsTo') {
                  attrs[key] = model.get(key).copy(true);
              } else if(relationship.kind == 'hasMany' && Ember.isArray(attrs[key])) {
                  attrs[key].splice(0);
                  model.get(key).forEach(function(obj) {
                      attrs[key].addObject(obj.copy(true));
                  });
              }
          });
      }
      return this.store.createRecord(root, attrs);
    }
});

Add the mixin in your model,

Note: If you want to clone your child model then, you need to include the mixin in child model as well

USAGE:

1. With relationship : YOURMODEL.copy(true)

2. Without relationship : YOURMODEL.copy()
