Description

Difficulty: Easy in progress Priority: Low Skill: Ember.js

Problem

We have a number of places where we ask a user to confirm before leaving the page. We could write a mixin to help clean up this logic.

export default Ember.Mixin.extend({;
  modelName: null,
  message: 'You will lose any unsaved information if you leave this page. Are you sure?',
  
  actions: {
    willTransition() {
      let modelName = get(this, 'modelName');
      if (isPresent(modelName)) {
         let model = get(this, modelName);
         if (get(modelName, 'isNew') {
           this._confirmTransition(transition, model);
         } 
      } else {
        this._confirmTransition(transition);
      }
    }
  },

  _confirmTransition(transition, model) {
    let message = get(this, 'message');
    if (window.confirm(message)) {
      if isPresent(model) {
        model.destroyRecord();
      }
    } else {
      transition.abort();
    }
  }
})
