如何检索 Ember.js 模型的所有属性 [英] How to retrieve all properties of an Ember.js model

问题描述

我正在 Ember.js 中处理表单，我想检索所有模型属性的列表，以便我可以在不同时刻拍摄表单状态的快照.有没有办法获取模型所有属性的列表?

I'm working with forms in Ember.js and I want to retrieve a list of all model properties so that I can take snapshots of the state of the form at different moments. Is there a way to get a list of all properties of a model?

例如，如果我的模型是:

For example, if my model is:

App.User = DS.Model.extend({
  name: DS.attr('string'),
  email: DS.attr('string'),
  current_password: DS.attr('string'),
  password: DS.attr('string'),
  password_confirmation: DS.attr('string'),
  admin: DS.attr('boolean'),
}

那么我想要这样的东西:

Then I would like to have something like this:

> getEmberProps('User')

["name", "email", "current_password", "password", "password_confirmation", "admin"]

推荐答案

你可以简单地使用 toJSON 方法并从对象中获取键.

You can simply use toJSON method on model and get the keys from object.

Ember.keys(model.toJSON())

请注意，不会返回您的关系密钥.

Note that will not return you keys for relations.
