Rails的未初始化的常量路由錯誤

Question

我知道這個問題是在網絡上貼滿了，但看着所有的答案後，我仍然無法弄清楚我的問題是什麼。

這裏是我的路線：

resources :applications do 
    resources :applicants do 
    collection {put '/archived'} 
    collection {put '/not_archived'} 
    end 
end 

然後我有一個表，在此路徑：/applications/1/applicants這就要求我的索引方法。

在此表中列出了所有的申請者，我有各行的複選框，當他們選中該複選框，我想設置的「歸檔」標誌的分貝使用AJAX該行。

這裏是我的Ajax調用：

$('.archive').on('click', function() { 
    if ($(this).is(':checked')) { 
     $.ajax({ 
      type: "PUT", 
      url: '/applications/<%= @application.id %>/applicants/archived', 
      data: {id: $(this).attr('id'), archived: true} 
     }); 
    } else { 
     $.ajax({ 
      type: "PUT", 
      url: '/applications/<%= @application.id %>/applicants/not_archived', 
      data: {id: $(this).attr('id'), archived: false} 
     }); 
    } 
}); 

但每次我選中一個複選框，我得到這個錯誤：

Started PUT "/applications/1/applicants/archived" for 127.0.0.1 at 2013-04-03 00:07:20 -0500

我ApplicantsController有以下方法：

# PUT /applicants/archived/1 
    def archived 
    p 'here?' 
    @applicant = Applicant.find(params[:id]) 
    @applicant.archived = params[:archived] 
    #@application = current_company.applications.find(params[:application_id]) 

    respond_to do |format| 
     if @applicant.save 
     format.js 
     #format.html { redirect_to @task, notice: 'Task was successfully updated.' } 
     #format.json { head :no_content } 
     else 
     format.html { render action: "index" } 
     format.json { render json: @applicant.errors, status: :unprocessable_entity } 
     end 
    end 
    end 

    # PUT /applicants/not_archived/1 
    def not_archived 
    @applicant = Applicant.find(params[:id]) 
    @applicant.archived = params[:archived] 
    #@application = current_company.applications.find(params[:application_id]) 

    respond_to do |format| 
     if @applicant.save 
     format.js 
     #format.html { redirect_to @task, notice: 'Task was successfully updated.' } 
     #format.json { head :no_content } 
     else 
     format.html { render action: "index" } 
     format.json { render json: @applicant.errors, status: :unprocessable_entity } 
     end 
    end 
    end 

這裏是我的耙線路輸出這些路線：

 archived_application_applicants PUT /applications/:application_id/applicants/archived(.:format)       applications/:application_id/applicants#archived 
    not_archived_application_applicants PUT /applications/:application_id/applicants/not_archived(.:format)      applications/:application_id/applicants#not_archived 
       application_applicants GET /applications/:application_id/applicants(.:format)          applicants#index 
             POST /applications/:application_id/applicants(.:format)          applicants#create 
       new_application_applicant GET /applications/:application_id/applicants/new(.:format)         applicants#new 
      edit_application_applicant GET /applications/:application_id/applicants/:id/edit(.:format)       applicants#edit 
        application_applicant GET /applications/:application_id/applicants/:id(.:format)         applicants#show 
             PUT /applications/:application_id/applicants/:id(.:format)         applicants#update 
             DELETE /applications/:application_id/applicants/:id(.:format)         applicants#destroy 

什麼引起我的錯誤？我完全被難住了。

Answer 1

我已經做了演示應用程序複製你的背景和它爲我工作得很好。您可以點擊此處查看：https://github.com/Chipairon/so_applicants_route

我已清理與它周圍爲你服務爲出發點，希望這一問題的噪音。

我沒有足夠的信譽評論你的問題，所以我把它放在這裏:)

我認爲這個問題必須是在你的app/views/applicants/archived.js.erb既然你說，當你選中一個複選框出現問題。你能發佈該文件的內容嗎？

在一個側面說明，我希望你能考慮使「存檔」行動成員的行動。你是做真正在一個單一的申請人動作，而不是對所有申請人：

resources :applications do 
    resources :applicants do 
    put :archived, on: :member 
    put :not_archived, on: :member 
    end 
end 

Answer 2

嘗試

$('.archive').on('click', function() { 
    if ($(this).is(':checked')){ 
     $.ajax({ 
      type: "PUT", 
      url: '<%= archived_application_applicants_path(:application_id => @application.id) %>', 
      data: {id: $(this).attr('id'), archived: true} 
    }); 
    }else { 
    $.ajax({ 
      type: "PUT", 
      url: '<%= not_archived_application_applicants_path(:application_id => @application.id) %>', 
      data: {id: $(this).attr('id'), archived: true} 
    }); 
    } 

}); 

Answer 3

我希望這段代碼會爲你工作：

$('.archive').on('click', function() {              

if ($(this).is(':checked')){ 
    $.ajax({ 
     type: "PUT", 
     url: '<%= archived_application_applicants_path(@application.id) %>', 
     data: {id: $(this).attr('id'), archived: true} 
    }); 
}else { 
    $.ajax({ 
     type: "PUT", 
     url: '<%= not_archived_application_applicants_path(@application.id) %>', 
     data: {id: $(this).attr('id'), archived: false} 
    }); 
} 

}); 

Answer 4

這可能無關，與你的JavaScript。路由器不能找到合適的一組模塊/類的解決將請求發送到控制器。

我的猜測是，你ApplicantsController被命名空間，像這樣：

class Applications::ApplicantsController < Superclass; 
end 

但applicants_controller.rb是不是在應用程序/控制器/應用程序，其將需要作出的Rails自動地創建應用程序模塊。移動applicants_controller.rb或刪除命名空間，並且事情應該自行修復。
