Rails 识别未知的 url 参数

Question

我不知道为什么，但最近我尝试更改路线以将新项目添加到

/project/new 而不是渲染 new.html.haml 它渲染 show.html.haml 并且 new 是参数。

在我的 routes.rb 中

Mika::Application.routes.draw do
  root "pages#home"
  get '/contact' => "pages#contact"
  get '/about' => 'pages#about'
  get '/privacy' => 'pages#privacy'
  get '/tos' => 'pages#terms_of_service'

  post '/contact' => 'messages#contact'

  resources :projects, :only => [:index, :show]
  resources :projects, :only => [:update, :edit, :create, :post, :new], :constraints => { :subdomain => 'admin' }
end

我不完全确定从哪里解决这个问题，甚至什么时候开始

在终端我得到了这个

Started GET "/projects/new" for 127.0.0.1 at 2014-05-16 15:23:20 -0700
Processing by ProjectsController#show as HTML

*EDIT 将路由文件更改为此工作

resources :projects, :only => [:update, :edit, :create, :post, :new], :constraints => { :subdomain => 'admin' }
resources :projects, :only => [:index, :show]

但它仍在为不存在的参数渲染创建，结果为空白页

您已经为 show 和 new 定义了这些 url：

project       GET /projects/:id(.:format)  projects#show
new_project   GET /projects/new(.:format)  projects#new {:subdomain=>"admin"}

因此，如果您不使用管理子域并输入 url /projects/new 路由器将其匹配到更通用的项目/节目。使用 url 格式 /projects/:id 将字符串 new 解释为 id。

Processing by ProjectsController#show as HTML
Parameters: {"id"=>"new"}

因此，如果您想使用或不使用 admin 子域访问 projects/new，只需在路由中指定：

resources :projects, :only => [:index, :show, :new]
resources :projects, :only => [:update, :edit, :create, :post, :new], :constraints => { :subdomain => 'admin' }
