验证在ruby中删除之前的对象集合

我想只允许删除，如果有多个用户与角色“所有者”。我想显示一条错误消息，告知他们无法删除该用户（包含角色所有者），如果它是唯一所有者。这是表格的样子。验证在ruby中删除之前的对象集合

def destroy 
    @user = @organization.users 
    .active 
    .find(params[:id]) 

    lastOwner = @organization.users 
    .active 
    .where(role: "owner") 
    .where.not(id: @user.id) 
    .count 
    .zero? 

    if lastOwner 
    flash[:error] = "There must always be at least one owner, please give another user the role first" 
    redirect_to teams_path 
    return 
    else 
    if @user && @user.archive! 

     respond_to do |format| 
     format.html { redirect_to teams_path } 
     format.json { head :no_content } 
     format.js { render :layout => false } 
     end 
    end 
    end 
end

这是我破坏方法。

正在发生的事情是，我尝试重定向，但我收到错误

一次，我收到的记录也没有T删除错误，但没有闪过这个错误消息，但页面重定向。当我刷新页面时，当我看到错误信息。请任何帮助，并感谢你！

这是删除

link_to('', team_path(user), method: :delete, data: {confirm: "Are you sure you want to delete this member?"}, :remote => true, class: "btn btn-danger fa fa-trash delete_user")

这些代码是我的路线

teams GET /teams(.:format)           teams#index 
             POST /teams(.:format)           teams#create 
           new_team GET /teams/new(.:format)          teams#new 
           edit_team GET /teams/:id/edit(.:format)        teams#edit 
            team PATCH /teams/:id(.:format)          teams#update 
             PUT /teams/:id(.:format)          teams#update 
             DELETE /teams/:id(.:format)          teams#destroy

您要删除的链接有误。你可以编辑你的问题并添加相关的视图代码？屏幕截图没有提供信息。 – tadman

Ruby还强烈鼓励使用小写的变量和方法名称，所以'lastOwner'应该是'last_owner'。这是因为case在Ruby中有意义，常量的前缀是大写字母。 – tadman

你的'config/routes.rb'是怎么样的？你如何生成删除按钮？ – spickermann

尝试改变redirect_to teams_path到redirect_to teams_url在respond_to代码块。
