Jquery Rails ajax未定义的局部变量或方法

我正在尝试将ajax添加到我的应用程序中，以便用户可以在不重新加载页面的情况下跟随其他用户，但我遇到以下错误：

编辑-更正问题

undefined local variable or method `member' for #<#<Class:0x79c3cb0>:0x78b26e0>

Extracted source (around line #1):

$("#gl_follow_<%= member.id %>").html("<%= escape_javascript(render :partial => 'shared/follow_member2', :locals => {:member => @followable}) %>");

未定义的局部变量或方法“member”#
提取的源（第1行附近）：
$（“#gl_follow"”）html（'shared/follow_member2'，:locals=>{:member=>@followable}）%>”；

以下是我所有的相关代码：

我不确定我错过了什么。我已经能够让ajax在单个用户的页面上工作，但是当页面上列出了多个用户实例时，就无法让它工作

我使用

member.id

指定ajax需要使用哪个按钮

---

有人能帮我吗？提前感谢。

视图/遵循_members/create.js.erb模板引用@member.id，但我看不到它在您的代码中的任何位置被设置，其他所有内容都引用了当前_成员。如果可以从视图中访问

当前成员

，请将

@member.id

更改为

当前成员

？

基于您显示的代码，并猜测一些片段，我想您应该：

$("#gl_follow_<%= @followable.id %>").html...etc.

$（“gl#u follow”）html…等。

它正在调用此

。我删除了@，得到了这个错误

未定义的局部变量或方法“member”

。为什么它说它是未定义的？根据您所有的其他代码，看起来您应该使用

current_member

我使用member，这样我就可以指定ajax应该使用哪个按钮，因为有多个用户被列出并带有follow按钮。啊，是的，就是这样。我知道这是我忘记的事情。非常感谢。不用客气，很高兴这是一个简单的解决方案。不要把它当成个人问题，但我已经把你的问题提交给你了，因为这只是一个简单的打字错误，这个问题/答案可能不会帮助任何其他遇到它的人。
