沒有路線匹配{：action =>「update」，：controller =>「」 - Rails 5

我得到下面的錯誤，並不確定如何更正它 - 你的幫助將不勝感激。沒有路線匹配{：action =>「update」，：controller =>「」 - Rails 5

當在用戶顯示頁面，我不明白的錯誤，但是當在例如在任何其他網頁...如事件index.html頁面錯誤顯示

No route matches {:action=>"update", :controller=>"friendships", :friend_id=>#<User id: 5, email: "[email protected]"

    before_filter :setup_friends

    redirect_to :back 
    end 

    # Accepts a friend request. 
    # We'd rather call this "accept", but that's not allowed by Rails. 
    def update 
    @user = User.friendly.find(params[:user_id]) 
    @friend = User.friendly.find(params[:friend_id]) 
    if @user.requested_friends.include?(@friend) 
     Friendship.accept(@user, @friend) 
     flash[:notice] = "Connection with #{@friend.firstname} accepted!" 
    else 
     flash[:notice] = "No connect request from #{@friend.firstname}." 
    end 
    redirect_to :back

    def destroy 
    @user = User.friendly.find(params[:user_id]) 
    @friend = User.friendly.find(params[:friend_id]) 
    if @user.requested_friends.include?(@friend) #decline 
     Friendship.breakup(@user, @friend) 
     redirect_to :back 
    elsif @user.pending_friends.include?(@friend) #cancel 
     Friendship.breakup(@user, @friend) 
     redirect_to :back 
    elsif @user.friends.include?(@friend) #delete 
     Friendship.breakup(@user, @friend) 
     redirect_to :back 
    end 
    end 

    private 
    def setup_friends 
    @user = User.find(current_user.id) 
    @friend = User.find_by_email(params[:id]) 
    end 
end

我不確定如何解決這個錯誤，我試圖像下面，但不工作：

<span> 
    <%= form_for friendship, url: friendship_path(requester), method: :put do |f| %> 
    <%= f.hidden_field :user_id, value: current_user.id %> 
    <%= f.hidden_field :friend_id, value: requester.id %> 
    <%= submit_tag "Accept_test", controller: "friendships", action: "update", class: "btn btn_add_friend" %> 
    <% end %> 
</span>

我不明白你的背後設置了邏輯。你已經在創建方法中創建友誼了嗎？所以，只要接受者接受或拒絕，你只需要更新友好記錄的'接受'（或任何你命名的）值？無需傳遞各種身份證件，只有友情記錄的ID才足以完成所有交易。從我的角度來看，這從Rails的角度來看是不好的做法。 –

更新控制器等待id參數，而您傳遞的唯一參數是user_id和friend_id。

你可以改變你的路由下面

resources :friendships, only: [:create, :destroy] do 
    collection do 
    put :update 
    end 
end
