Custom POST routes for create action not fired up
提问by roychri
# Explaining the context
# 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! :)"
# The Problem
＃ 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
# 配置/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
I hope this problem is in the way I created the route. I tried many different things.
我希望这个问题是我创建路线的方式。我尝试了很多不同的东西。
# _form.html.erb
# _form.html.erb
<%= form_for(@forum) do |f| %>
....
<% end %>
I am using standard form_for helper.
我正在使用标准的 form_for 助手。
# Rake Routes for Forums
# 论坛的 Rake 路线
$ 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
We clearly see a route for POST /helpcenter which is binded to the create action of the forums controller.
我们清楚地看到 POST /helpcenter 的路由，它绑定到论坛控制器的创建操作。
# Logs
# 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"}
The logs clearly shows I am doing a POST on /helpcenter but that it fires up the index action instead of the create action!
日志清楚地显示我正在 /helpcenter 上执行 POST 但它启动了索引操作而不是创建操作！
# What am I doing wrong?
＃ 我究竟做错了什么？
puts "Thanks!"

I think the request matches your first forumsroute since you didn't specify a HTTP method. This should work:
我认为该请求与您的第一forums条路线匹配，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
Or the shorthand version:
或者简写版本：
get "/helpcenter" => "forums#index", :as => :forums
post "/helpcenter" => "forums#create", :as => :create_forum

First glance shows that a POST against /helpcenter passes the rule for the forums#index match, which is encountered first, so that's what you get
乍一看，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
What about:
关于什么：
match "/helpcenter" => "forums#index", :via => :get, :as => :forums
match "/helpcenter" => "forums#create", :via => :post, :as => :create_forum
