<% @user.requested_friends.each do |requester| %> 
    <tr> 
    <td><%= link_to(image_tag("img-profile-image-default.png"), requester) %></td>

routes文件

Rails.application.routes.draw do 
    resources :friendships, only: [:create, :update, :destroy] 
end 


      friendships POST /friendships(.:format)   friendships#create 
       friendship PATCH /friendships/:id(.:format)  friendships#update 
         PUT /friendships/:id(.:format)  friendships#update 
         DELETE /friendships/:id(.:format)  friendships#destroy

因爲你不具備接受或拒絕任何途徑。只有創建，更新，銷燬，正如我所看到的。你在友誼控制器中這樣做，所以在我看來，最好將友誼標識作爲主要參數。你能做到這樣

resources :friendships, only: [:create, :update, :destroy] do 
member do 
    post :accept 
    post :decline 
end 
end

這將創建你的路線和路徑傭工像

accept_friendship_path(id: friendship.id) 
decline_friendship_path(id: friendship.id)

或者你可以使用

accept_friendship_path(friendship)

，您仍然可以發送朋友id爲PARAM加入它以這樣的方式進行鏈接

link_to "Accept", accept_friendship_path(friendship, friend_id: requester.id)
