ruby-on-rails – routes.rb – 不支持控制器名称

resources :players
match '/players/:userid',:to => 'Players#show'

当您访问localhost：3000 / players / 1234时,会出现此错误：

‘Players’ is not a supported controller name. This can lead to potential routing problems.

控制器中的相关代码：

def show
  begin
    if Player.find_by(:uid => :userid) then
      @playerattributes = Player.find_by(:uid => :userid) 
      if player[:profile_complete] == true then
        @playerinfo = {
            :age => player[:age],:team => player[:team],:position => player[:position]
        }
      else
        @playerinfo = 0 
      end
    end
    player = Player.find_by(:uid => :userid)[:info]
rescue ActiveRecord::RecordNotFound
    redirect_to root_url        
    end
end

问题并没有就此结束.当页面加载时(它有时随机工作),这一行起作用：
如果是Player.find_by(：uid =>：userid)那么
使用PostgreSQL,显示查询.它不是使用URL中的：userid值(即localhost：3000 / players / 1234将是1234),而只是输入文本“userid”.

我错过了一些明显的东西吗

真的很感激任何帮助.
