没有路线匹配{：action=>“显示”，：controller=>“锦标赛”}，但rake路线显示tournaments#show

Question

错误:没有路线匹配{：action=>“显示”，：controller=>“锦标赛”}

class TournamentsController < ApplicationController
  def new
    @tournament = Tournament.new
  end

  def create
    @tournament = Tournament.new(params[:tournament].permit(:description))
    if @tournament.save
      #flash[:notice] = 'tournament was successfully created.'
      #set up links


      redirect_to :action => 'show'
    else
      render :action => 'new'
    end
  end

  def show
    @tournament = Tournament.first
  end
end

routes.rb：

  resources :tournaments do 
    member do
      get "results"
    end

    resources :opportunities do
      member do
        get 'rate'
      end
    end
  end

执行rake路线显示：

..。

tournament GET    /tournaments/:id(.:format)       tournaments#show

..。

我做错了什么？(将随着我完成这一期“新报”的进展而更新)

Answer 1

您必须提供您希望显示的锦标赛实例的ID。它就像:id一样出现在rake routes输出中。

如果在执行create操作时出现错误，则可能需要redirect_to tournament_path(@tournament) (或仅redirect_to @tournament)。
