Question

我正在玩SailsJS，我得到了以下观点：

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

使用以下控制器：

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

路线：

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

导航到真正的简单设置时，我得到以下内容：

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

任何人都可以解释我做错了什么吗？谢谢！

修改 - 我应该指出，我已尝试过各种形式的req.param('category')和req.params.category等等......

Answer 1

而不是使用

req.param('category')

此

req.params.id

应该解决你的问题。但是req.param('category')应该也可以正常运行，而且从代码中我看不出为什么它不起作用。

SailsJS将数据传递给视图 - 未定义
