SailsJS傳遞數據，查看 - 未定義

我打約與SailsJS和我有以下看法：SailsJS傳遞數據，查看 - 未定義

<p>Products <%= category %></p>

用下面的控制器：

module.exports = { 
    get: function(req, res) { 
     res.view('pages/products', { 
      category: req.params.category 
     }); 
    } 
};

和路由：

'/products/:category': 'ProductsController.get',

當導航到這個真的簡單的設置，我得到以下內容：

error: Sending 500 ("Server Error") response: 
ReferenceError: /var/www/html/curioushaven/views/pages/products.ejs:1 
>> 1| <p>Products <%= category %></p> 
    2| 

category is not defined

任何人都可以解釋我做錯了什麼？謝謝！

編輯 - 我要指出，我已經試過各種形式的req.param('category')和req.params.category等等...

我無法用您提供的代碼重現此問題 - 它對我來說看起來不錯。你使用的是什麼版本的Sails？ – sgress454

而不是使用

req.param('category')

這

req.params.id

應該解決你的問題。然而req.param('category')應該也能工作，並且從你的代碼我看不出爲什麼它不應該工作。
