我在Javascript ERB文件中有以下代码:
$(document).ready(function() {
$("#workout-week").append(
<%= escape_javascript(render :partial => "show_training_period", :locals => { :period => @period }) %>
);
});
进入 View 时，出现以下错误:
undefined method `render' for #<#<Class:0x00000004e21158>:0x00000005dbfe98>
部分存在，并且局部变量为非零。知道为什么会发生这种情况吗？

最佳答案
您正在尝试使用 Assets 中的render。不幸的是，现在不可能，看看this。
关于javascript - Rails js.erb文件找不到方法 “render”，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/8370399/
