[英]How to properly set up the Backbone.js urlRoot method
I am having trouble understanding how urlRoot
works in Backbone.js. 我无法理解urlRoot
在Backbone.js中的工作方式。 I am attempting to fetch a task with a specific _id
from a NodeJS/MongoDB backend. 我正在尝试从NodeJS / MongoDB后端获取具有特定_id
的任务。
What I'm not exactly clear on is how to pass the id attribute into the URI. 我不清楚的是如何将id属性传递到URI中。 I've been doing the following from Chrome dev tools: 我一直在使用Chrome开发者工具执行以下操作:
var task = new App.Models.Task({ id: '51c09ae7d3b35d29d4dfdecd' });
task.fetch();
And I receive the following error: 而且我收到以下错误:
GET http://localhost:3000/tasks/:_id 500 (Internal Server Error)
How do I properly set this up? 如何正确设置?
Here's my Backbone code: 这是我的骨干网代码:
(function() {
window.App = {
Models: {},
Views: {},
Collections: {}
};
App.Models.Task = Backbone.Model.extend({
defaults: {
title: '',
completed: false
},
idAttribute: "_id",
urlRoot: '/tasks/:_id'
});
})();
Looking at http://backbonetutorials.com/what-is-a-model/ for guidance I would say you don't need to define the idAttribute and your urlRoot should just be "/tasks". 查看http://backbonetutorials.com/what-is-a-model/以获得指导,我会说您不需要定义idAttribute,而urlRoot应该只是“ / tasks”。 Backbone should handle the rest. 骨干应该处理其余的事情。
Note: I haven't used Backbone myself yet but have been reading up on it. 注意:我自己还没有使用过Backbone,但一直在阅读。
