添加PgSearch到Rails應用程序：`的ActiveRecord :: RecordNotFound`

我想回形針添加到Forem-based Rails app：添加PgSearch到Rails應用程序：`的ActiveRecord :: RecordNotFound`

直播應用：http://runnable.com/VEFe5hZXSE9z0q5x/forem-with-pgsearch-for-ruby-on-rails（擊中Run按鈕之前運行/etc/init.d/postgresql start）

但爲什麼儘管搜索存在的帖子，我是不是在收到ActiveRecord::RecordNotFound？

app/decorators/models/forem/topic_decorator.rb

Forem::Topic.class_eval do 
    include PgSearch 

    pg_search_scope :search, against: [:subject], using: { tsearch: { dictionary: "english" } }, associated_against: { posts: [:text] } 
end

app/decorators/controllers/forem/forums_controller_decorator.rb

Forem::ForumsController.class_eval do 
    def search 
    @search = params[:keywords] 
    @topics = Forem::Topic.search(@search) 
    end 
end

app/views/layouts/application.html.erb

<div class="search"> 
    <%= form_tag main_app.search_path, method: :get do %> 
    <label for="search">Search</label> 
    <%= search_field_tag :keywords, params[:keywords], id: "search" %> 
    <% end %> 
</div>

app/views/forem/forums/search.html.erb

<h1>Search results</h1> 
<%= render @topics %>

config/routes.rb

get '/search', to: 'forem/forums#search', as: 'search'

當搜索Mangos：

- 其通過rake db:seed加入：

db/seeds.rb

Forem::Category.create!(:name => 'General') 

user = User.create(
    :email => "[email protected]", 
    :password => "admin1234" 
) 
user.forem_admin = true 
user.save! 
user.update_attribute(:forem_state, 'approved') 

unless user.nil? 
    forum = Forem::Forum.create(:category_id => Forem::Category.first.id, :name => "Default", :description => "Default forem created by install") 

    topic1 = forum.topics.build({ :subject => "Apples", :posts_attributes => [:text => "Eat apples"] }) 
    topic1.user = user 
    topic1.save! 

    topic2 = forum.topics.build({ :subject => "Bananas", :posts_attributes => [:text => "Eat bananas"] }) 
    topic2.user = user 
    topic2.save! 

    topic3 = forum.topics.build({ :subject => "Oranges", :posts_attributes => [:text => "Eat oranges"] }) 
    topic3.user = user 
    topic3.save! 

    topic4 = forum.topics.build({ :subject => "Mangos", :posts_attributes => [:text => "Eat mangos"] }) 
    topic4.user = user 
    topic4.save! 
end

哇，與downvotes什麼？ – 2014-10-17 23:29:26

這似乎是一個路由問題（您的'搜索'路線被覆蓋）。發佈您的路線文件。 – Substantial 2014-10-17 23:54:21

嗨！謝啦。只是這個：https：//gist.github.com/anonymous/6aff4926bdba9b99e571 – 2014-10-17 23:59:45

日誌輸出顯示Forem::ForumsController#show動作被調用，而不是搜索：

Started GET "/search?utf8=%E2%9C%93&keywords=Mangos" at 2014-10-17 19:33:15 +0000 
Processing by Forem::ForumsController#show as HTML

你的搜索路徑正在被培訓就業部引擎路線覆蓋，特別是this resourceful route attached to root：

resources :forums, :only => [:index, :show], :path => "/" do 
    # ...snipped...

/被映射到論壇索引，並且/search被映射到論壇展示（具有ID：「搜索」，如所記錄的SQL輸出中所示）。

爲了解決這個問題，移動FOREM引擎上方的「搜索」路線，如路由優先級頂至底：

App::Application.routes.draw do 
    get '/search', to: 'forem/forums#search', as: 'search' 
    mount Forem::Engine, :at => '/' 
    devise_for :users 
end

不錯！這似乎已經做到了，但是現在我面臨着Forem :: Forums＃search中的ActionController :: UrlGenerationError（請參閱更新後的實時沙盒應用程序）。你知道這是否相關嗎？ – 2014-10-18 00:38:35

在** app/views/forem/topics/_topic.html.erb：20 **路由幫助參數爲零。 '@ forum'通常由[此私有控制器方法]（https://github.com/radar/forem/blob/rails4/app/controllers/forem/topics_controller.rb#L98）定義，但當前的搜索處理結果不會使用它並留下'@ forum'nil。髒修復：用'（@forum || topic.forum_id）'替換'@ forum';這將使搜索工作暫時停止，但它將繞過查看計數和「讀取」授權（向未授權閱讀的用戶列出主題），因此請勿將其用於生產。 – Substantial 2014-10-18 06:32:33

非常感謝你真實！骯髒的修復是現在好:) – 2014-10-18 11:30:41
