将流星集合用于Typeahead猎犬，最好不要制作自己的API

问题描述

我想构建一个类似于StackOverflow的标签输入。我正在尝试使用Meteor集合作为 ，因为我最终希望使用。

I want to build a tags input like the one in StackOverflow. I am trying to use Meteor collections as the remote or prefetch data for Typeahead Bloodhound because I want to eventually use Bootstrap Tokenfield.

根据他们的文档和示例，绝对需要JSON数据的网址。我怎样才能（最好是反应性地）将数据提供给Bloodhound？我已经研究了，但我不知道如何将其与。

According to their documentation and examples, a url to the JSON data is absolutely required. How can I provide the data, preferably reactively, to Bloodhound? I have looked into the Meteor Typeahead package, but I can't figure out how to use it with the Meteor Tokenfield package.

以下是我尝试执行的操作，但是没有用。 ：（

Below is what I've tried to do, but it doesn't work. :(

<div class="control-group">
    <label class="control-label" for="users">Users</label>
    <div class="controls">
      <input type="text" class="form-control" id="tokenfield-typeahead-users" value="" />
    </div>
</div>

Template.viewUsers.rendered = function() {
    var users = new Bloodhound({
      datumTokenizer: function(d) {
        return Bloodhound.tokenizers.whitespace(d.username);
      },
      queryTokenizer: Bloodhound.tokenizers.whitespace,
      limit: 20,
      remote: {
        // url points to a json file that contains an array of tokens
        url: function() {
          return Meteor.users.find().fetch().map(function(user){ return user.username; });
        }
      }
    });

    users.initialize();// kicks off the loading/processing of `local` and `prefetch`

    // passing in `null` for the `options` arguments will result in the default
    // options being used
    $('#tokenfield-typeahead-users').tokenfield({
      typeahead: [null, {
        name: 'users',
        displayKey: 'username',
        source: users.ttAdapter()
        // `ttAdapter` wraps the suggestion engine in an adapter that
        // is compatible with the typeahead jQuery plugin
      }]
    });
};

我宁愿不构建API，但是如果需要的话，如何提供数据？

I prefer not to build an API, but if I have to, how do I provide the data?

推荐答案

使用：

    local: [{ val: 'dog' }, { val: 'pig' }, { val: 'moose' }],
