# 解释上下文

puts "I am learning Rails, building a simple forum application."
puts "I am pretty satisfied to where I got so far but routes... "
puts "...still figuring them out."
puts "Been 2 days trying all sorts of things."
puts "This is where I am now, and something is not working as expected."
puts "Any help/pointers would be appreciated! :)"

# 问题

puts "I want my forum's create path to be '/helpcenter' and not '/helpcenter/cat'."
puts "When I access the form to create a new forum and I hit submit, "
puts "the form post to '/helpcenter' correctly (firebuged)"
puts "but I get the index, not the create!"
puts "I even put debugger in my create action but it is not being called."

#config/routes.rb

scope "/helpcenter" do
  resources :cat, :controller => "forums", :as => :forums do
    resources :topics , :controller => "forum_topics", :as => :topics
    resources :posts, :controller => "forum_posts", :as => :posts
  end
end

match "/helpcenter" => "forums#index", :as => :forums
match "/helpcenter" => "forums#create", :via => :post, :as => :create_forum

我希望这个问题出在我创建路线的方式上。我尝试了很多不同的东西。

# _form.html.erb

<%= form_for(@forum) do |f| %>
....
<% end %>

我正在使用标准的 form_for 助手。

# 论坛的 Rake 路由

$ CONTROLLER=forums rake routes
delete_forum GET    /helpcenter/cat/:id/delete(.:format) forums#delete
      forums GET    /helpcenter/cat(.:format)            forums#index
             POST   /helpcenter/cat(.:format)            forums#create
   new_forum GET    /helpcenter/cat/new(.:format)        forums#new
  edit_forum GET    /helpcenter/cat/:id/edit(.:format)   forums#edit
       forum GET    /helpcenter/cat/:id(.:format)        forums#show
             PUT    /helpcenter/cat/:id(.:format)        forums#update
             DELETE /helpcenter/cat/:id(.:format)        forums#destroy
      forums        /helpcenter(.:format)                forums#index
create_forum POST   /helpcenter(.:format)                forums#create

我们清楚地看到 POST /helpcenter 的路由绑定到论坛控制器的创建操作。

# 日志

Started POST "/helpcenter" for 127.0.0.1 at 2012-07-02 12:25:00 -0400
Processing by ForumsController#index as HTML
  Parameters: {"utf8"=>"✓", "authenticity_token"=>"d5iVKCh234234=", "forum"=>{"name"=>"", "description"=>""}, "commit"=>"Save Changes"}

日志清楚地显示我正在 /helpcenter 上进行 POST，但它会触发 index 操作而不是 create 操作！

#我做错了什么？

puts "Thanks!"

【解决方案1】：

我认为该请求与您的第一个 forums 路由匹配，因为您没有指定 HTTP 方法。这应该有效：

match "/helpcenter" => "forums#index", :via => :get, :as => :forums
match "/helpcenter" => "forums#create", :via => :post, :as => :create_forum

或简写版本：

get "/helpcenter" => "forums#index", :as => :forums
post "/helpcenter" => "forums#create", :as => :create_forum

乍一看表明，针对 /helpcenter 的 POST 通过了 forums#index 匹配的规则，这是首先遇到的，所以这就是你得到的

match "/helpcenter" => "forums#index", :as => :forums
match "/helpcenter" => "forums#create", :via => :post, :as => :create_forum

怎么样：

match "/helpcenter" => "forums#index", :via => :get, :as => :forums
match "/helpcenter" => "forums#create", :via => :post, :as => :create_forum
