Sails.js - Controller正在渲染视图,但未定义集合

使用新控制器尝试Sails,但视图无法正确呈现。 我的控制器看起来像这样:

/**
 * QuestionController
 *
 * @module      :: Controller
 * @description :: Contains logic for handling requests.
 */

module.exports = {

  /* e.g.
  sayHello: function (req, res) {
    res.send('hello world!');
  }
  */
  index: function (req, res) {
    return res.view({
      questions: [{title: 'Freddy a presidente?', content: 'Últimamente Freddy se encuentra con más diplomacia.'}]
    });
  }


};

虽然我的观点如下:

<h1>Preguntas</h1>
<ul>
  <% _.each(questions, function(question) { %>
  <li><%= question.title %></li>
  <% }) %>
</ul>

但我收到以下错误:

ReferenceError: /home/alainus/dev/parlamenta/parlamenta/views/question/index.ejs:3
    1| <h1>Preguntas</h1>
    2| <ul>
 >> 3|   <% _.each(questions, function(question) { %>
    4|   <li><%= question.title %></li>
    5|   <% }) %>
    6| </ul>

questions is not defined

关于如何使这项工作的任何想法?

尝试引用问题

return res.view({
  "questions": [{title: 'Freddy a presidente?', content: 'Últimamente Freddy se encuentra con más diplomacia.'}]
});

您的路由如何在config \ routes.js中定义?

我猜你的代码看起来像是:'/':{view:'main',action:'index'} ,但这只是渲染视图而不调用控制器。

尝试类似:'/':{controller:'main',action:'index'}

此致

哈里什雷迪似乎已经钉了它。

SailsJs文档显示了一个没有引号的视图变量示例:

    return res.view({
        corndogs: [{name: 'Hank the Corndog'}, {name: 'Lenny the Corndog'}]
    });

......但这对我不起作用。我不确定为什么。如果我引用变量名称就可以了。

    return res.view({
       "corndogs": [{name: 'Hank the Corndog'}, {name: 'Lenny the Corndog'}]
    });
