Question

在我学习Ember的过程中，我试图让Ember向/ api / posts发出GET请求，并通过把手显示帖子列表。

现在，它已经成功获得了get请求，但chrome会弹出这些错误 -

TypeError: undefined is not a function

Uncaught Error: Assertion Failed: TypeError: undefined is not a function ember.js?body=1:74

这是我的应用程序到目前为止的样子 -

// http://emberjs.com/guides/models/using-the-store/
Blog.Store = DS.Store.extend({
  adapter: 'Blog.ApplicationAdapter'
});

Blog.ApplicationAdapter = DS.RESTAdapter.extend({
    namespace: 'api'
})

// For more information see: http://emberjs.com/guides/routing/
Blog.Router.map(function() {
  this.resource('posts');
});

#posts.handlebars
<h1>Entries...</h1>
{{#each post in controller}}
  {{render "post" post}}
{{/each}}    

#post.handlebars
<h2>{{title}}</h2>

Blog.PostsRoute = Ember.Route.extend({
  model: function() {
    return this.get('store').findAll('Post')
  }
})
Blog.Post = DS.Model.extend({});

我该怎么做呢？

Answer 1

而不是：

Blog.PostsRoute = Ember.Route.extend({
  model: function() {
    return this.get('store').findAll('Post')
  }
})

我写道：

Blog.PostsRoute = Ember.Route.extend({
  model: function() {
    return this.get('store').find('post')
  }
})

Ember＆＃39; undefined不是一个功能＆＃39;获取发布api的请求
