Ember.js 模型中的保留属性名称 [英] Reserved attribute names in Ember.js models
问题描述
我有一个包含以下字段的 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,不是Post.content,结果如下:
After rendering, instead of the Post.content, the result is like:
<BlogApp.Post:ember272:1>
其他字段渲染正常.我猜 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:
- 当 REST API 的名称与 Ember 内部结构冲突时,是否有任何解决方法?
- 还有其他我应该注意的禁用属性名称吗?
[更新]
名称冲突与控制器有关,与模型无关.这不是一个明确的列表,但要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
- is_deleted
- 商店
- 错误
我猜 Ember 开发人员不像这个可怜的 Python 专家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 伙计们说得对:他们总是在 API 属性和方法前面加上 $
有效防止此类错误.
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
我想回答你的两个问题:
I'm trying to answer your two questions:
1您可以为所有键定义映射,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,ember 中没有这样的 explicit
保留名称列表,但根据经验,应该避免使用非常通用的名称,例如 content
(预防性)
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)
