railway.js中嵌套的资源：说不能POST

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）。

我试图让嵌套的资源工作。 我做了以下的脚手架命令：

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

然后我改变了routes.js文件到：

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

做railway r给我所希望的：

  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，添加一个用户（恰好是4e4b61e39f0d60d834000002），然后去http：// localhost：3000 / users / 4e4b61e39f0d60d834000002 /设置/新 ，它说我“不能POST”。

我错过了什么？ 什么是好的debugging方法？

我也尝试在UserSchema对象中添加一个元素： setups: [SetupSchema] 。 （我们不应该这样做吗？）

提前致谢。

Answer 1

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 - }); 

Answer 2

看看文件app/views/setups/new.ejs ：

 <h1>New setup</h1> <% form_for(setup, {action: path_to.setups, method: 'POST', id: "setup_form"}, function (form) { %> <%- partial('setups/form.ejs', {locals: {form: form, setup: setup}}) %> <%- form.submit('Create setup') %> or <%- link_to('Cancel', path_to.setups) %> <% });%> 

它指的是不存在的pathpath_to.setups，您必须将其更改为正确的pathpath_to.user_setups：

 <h1>New setup</h1> <% form_for(setup, {action: path_to.user_setups(user), method: 'POST', id: "setup_form"}, function (form) { %> <%- partial('setups/form.ejs', {locals: {form: form, setup: setup}}) %> <%- form.submit('Create setup') %> or <%- link_to('Cancel', path_to.setups) %> <% });%> 

所以，你将POST到/users/…/setups而不是POST到/users/…/setups/new。

请注意，你需要传递用户作为path_to helper的第一个参数，所以铁路将为你build立正确的路线。
