所以我一直试图在名为＆＃34; metasploit_host_notes的表中显示来自mysql数据库的数据。我想在现有的表格中添加一个标签，名为＆＃34; Notes＆＃34;并显示该数据。我不知道我错过了什么，但我一直收到这个错误：
显示 /Users/angelispseftis/RubymineProjects/vapt/app/views/engagements/_metasploit_tabview.erb 第40行引出的地方：

答案 0 :(得分：0)
第二个＆＃34; metasploit_host_notes＆＃34;第40行基本上是方法调用或局部变量。
{metasploit_host_notes: metasploit_host_notes}
我猜你没有定义一个名为metasploit_host_notes的辅助方法，显然没有该名称的局部变量。我猜的是你想传递一个具有该名称的实例变量（@metasploit_host_notes）。将控制器中的变量定义为正确的值，并将该段代码更改为：
{metasploit_host_notes: @metasploit_host_notes}
