Ember.js模型中的保留属性名称 [英] Reserved attribute names in Ember.js models

问题描述

我有一个具有以下字段的Post模型:

I have a Post model with the following fields:

BlogApp.Post = DS.Model.extend({
    author: DS.attr('string'),
    title: DS.attr('string'),
    preamble: DS.attr('string'),
    content: DS.attr('string'),
    created: DS.attr('date'),
    comments: DS.hasMany('BlogApp.Comment'),
    lastUpdate: DS.attr('date')
});

渲染后，结果类似于Post.content:

After rendering, instead of the Post.content, the result is like:

<BlogApp.Post:ember272:1>

其他字段呈现都可以.我想content与某些内部属性冲突.我有几个问题:

Other fields rendering are OK. I guess content is conflicting with some internal property. I have a few questions:

1. 当REST API的名称与Ember内部有冲突时，是否有任何解决方法?
2. 我还应该知道其他禁止使用的属性名称吗?

[更新]

名称冲突与控制器有关，而与模型无关.它不是确定的列表，但请注意其他常见的数据库列名称，例如:

The name clash is with the controller, not with the model. It is not a definitive list but watch out for other common database column names like:

• 模型
• 交易
• is_new
• 已删除
• 商店
• 错误

我猜Ember开发人员并不像这个可怜的pythonist那样害怕与命名空间相关的错误.

I guess Ember developers not as afraid of namespace-related bugs as this poor pythonist.

顺便说一句， Angular.js 伙计们做对了:他们总是在API属性和方法上有效地加上$前缀防止这种错误.

BTW, Angular.js guys got it right: they always prefix API attributes and methods with $ effectively preventing this kind of bug.

推荐答案

我正在尝试回答您的两个问题:

I'm trying to answer your two questions:

1 您可以为所有键定义一个映射，这里是content属性的示例

1 you can define a mapping for all of you Keys, here an example for the content property

App.Adapter.map('App.Post', {
  myContent: {key: 'content'}
});

2 据我所知，在ember中没有这样的explicit保留名称列表，但是根据经验，应该避免(预防性地)像content这样的通用名称

2 as far I know there is no such explicit list of reserved names in ember, but as a rule of thumb very generic names like content should be avoided (preventively)
