node.js - Railway.js 中的嵌套资源 : Says cannot POST

Question

我正在尝试一个名为 railway.js 的 MVC 框架(它位于 Node、Express、Mongoose 和 Mongo 之上)。

我正在尝试让嵌套资源正常工作。我执行了以下脚手架命令:

railway g scaffold user name email description 
railway g scaffold setup title description

然后我将routes.js 文件更改为:

exports.routes = function (map) {
  map.resources('users',function(user) {
    user.resources('setups');
  });
});

做railway r给出了我所希望的:

     user_setups GET    /users/:user_id/setups.:format?          setups#index
     user_setups POST   /users/:user_id/setups.:format?          setups#create
  new_user_setup GET    /users/:user_id/setups/new.:format?      setups#new
 edit_user_setup GET    /users/:user_id/setups/:id/edit.:format? setups#edit
      user_setup DELETE /users/:user_id/setups/:id.:format?      setups#destroy
      user_setup PUT    /users/:user_id/setups/:id.:format?      setups#update
      user_setup GET    /users/:user_id/setups/:id.:format?      setups#show
           users GET    /users.:format?                          users#index
           users POST   /users.:format?                          users#create
        new_user GET    /users/new.:format?                      users#new
       edit_user GET    /users/:id/edit.:format?                 users#edit
            user DELETE /users/:id.:format?                      users#destroy
            user PUT    /users/:id.:format?                      users#update
            user GET    /users/:id.:format?                      users#show

当我启动服务器时，添加一个用户(恰好是4e4b61e39f0d60d834000002)，然后转到http://localhost:3000/users/4e4b61e39f0d60d834000002/setups/new ，它说我“无法发布”。

我错过了什么？什么是好的调试方法？

我还尝试将一个元素添加到 UserSchema 对象中:setups: [SetupSchema]。 (我们不应该这样做吗？)

提前致谢。

在你的setup_controller中:

before(loaduser);

...

function loadUser () {
User.findById(req.params.user_id, function (err, user) {
    if (err || !user) {
            redirect(path_to.users);
        } else {
            // this is where we make the actual user object accessible inside the view templating
            this.user = user;
            next();
        }
    }.bind(this));
}

在你的 setup/form.jade 中:

- form_for( setup, { method: 'POST', action: path_to.user_setups(user) }, function(form){
    //layout your form
- });
