如何在模板厨师中为每个循环运行 [英] How to Run for each loop in template chef

问题描述

我有一个数组形式的属性，我想在Chef模板中对其进行迭代？

I have a attribute in the form of array, and i want to iterate over it in Chef template ?

<% node['db2']['instance_username'].each do |device| -%> 
  <%= "/home/#{device}/sqllib/lib64" %>
<% end -%>

我正在这样做，但它给出了错误。

I'm doing like this but it is giving error.

推荐答案

<% 
node['db2']['instance_username'].each do |device| 
%> 
  /home/<%= device %>/sqllib/lib64
<% end %>

我会改成这样。如果您遇到错误，请尝试将结尾连字符找出来，它们是Rails的构造，我不确定它们是否能很好地交叉，但是如果您发布了所遇到的错误，这会很有帮助。实例用户名很可能不是数组。

I'd rewrite it like this instead. If you are having an error try taking out the end hyphens out they are a rails construct and I'm not sure if they cross over well but it would help a lot if you posted the error you are having. Most likely instance username is not an array.
