Rails link_to實例變量的記錄.count（）結果

Question

我在我的中有記錄提交者模型顯示在應用程序索引視圖顯示在下面的表中。只有我希望能夠點擊.count()列出的號碼，並將其帶到我的票務指數視圖，並列出所有相應的記錄（票證）。

我很難理解如何將實例變量鏈接到控制器的操作，以便使用我的視圖的佈局。

任何想法？

<table> 
    <tr> 
    <th>Name</th> 
    <th>Number of Tickets</th> 
    </th> 
    <tr> 
    <% Submitter.where(:school_id => current_user.school_id, :disabled => false).each do |sub| %> 
    <td><%= link_to sub.full_name, edit_submitter_path(sub) %></td> 
    <td><%= Ticket.where(:submitter_id => sub).count %></td> 
    </tr> 
    <% end %> 
</table>

resources :feedbacks 
resources :products 

get "password_resets/new" 
get 'signup', to: 'users#new', as: 'signup' 
get 'login', to: 'sessions#new', as: 'login' 
get 'logout', to: 'sessions#destroy', as: 'logout'

Answer 1

像這樣的事情可能？不是100％理解你的問題。

<table> 
    <tr> 
    <th>Name</th> 
    <th>Number of Tickets</th> 
    </th> 
    <tr> 
    <% Submitter.where(:school_id => current_user.school_id, :disabled => false).each do |sub| %> 
     <td><%= link_to sub.full_name, edit_submitter_path(sub) %></td> 
     <td><%= link_to pluralize(sub.tickets.count, 'ticket'), tickets_path %></td> 
    <% end %> 
    </tr> 
</table> 

我，當然，不能給你完美的工作代碼，除非我知道你config/routes.rb是什麼樣子，因爲我不知道什麼是你的門票索引視圖的方法。

聽起來好像你有一個提交者有很多票。如果是這樣，你會顯示一個提交者列表（在submitters_controller＃index方法中）並計算票數。然後將該號碼鏈接到tickets_controller＃index方法。像這樣...

的routes.rb

resources :submitters do 
    resources :tickets 
end 

submitters_controller.rb

class SubmittersController < ApplicationController 

    def index 
    @submitters = Submitter.where(:school_id => current_user.school_id, :disabled => false) 
    end 

end 

tickets_controller.rb

class TicketsController < ApplicationController 

    def index 
    @submitter = Submitter.find(params[:submitter_id]) 
    @tickets = @submitter.tickets 
    end 

end

    <th>Number of Tickets</th> 
    </th> 
    <% @submitters.each do |sub| %> 
    <tr> 
     <td><%= link_to sub.full_name, edit_submitter_path(sub) %></td> 
     <td><%= link_to pluralize(sub.tickets.count, 'ticket'), submitter_tickets_path(sub) %></td> 
    </tr> 
    <% end %> 
</table>
