Ideal ember model save function

model-save.js

import Ember from 'ember';


export function modelSave(subject, { successMsg, errorMsg, transitionPath, notifyLookupPath, confirmLookupPath, saveFunc }) {
  if (!saveFunc) {
    saveFunc = subject.save.bind(subject);
  }
  if (!notifyLookupPath) {
    notifyLookupPath = 'service:notify'
  }
  
  return Ember.Object.create({
    notify: Ember.computed(function() {
      return this.container.lookup(notifyLookupPath);
    }),
    
    save() {
      saveFunc.then(() => {
        let notify = this.get('notify');
        
        if (successMsg) {
          this.notify.success(successMsg);
        }
        
        if (transitionPath) {
          ... // Needs written, would be much easier to write in ember 2.2 with the more public router API
        }
      }).catch((e) => {
        if (errorMsg) {
          this.notify.error(errorMsg);
        }
        
        throw e;
      })
    }
  }).save();
