通过Rails中的hidden_​​field_tag传递数组 [英] Passing an array through a hidden_field_tag in Rails

问题描述

我确实在SO上找到了这个问题，但它没有真的没有帮助.

I did find this question on SO, but it didn't help, really.

所以，我想通过一个隐藏的字段标签传递一个数组.到目前为止，我的代码是:

So, I'd like to pass an array through a hidden field tag. As of now my code is:

<%= hidden_field_tag "article_ids", @articles.map(&:id) %>

这显然不起作用，因为它将id作为字符串传递.

This obviously does not work since it passes the ids as a string.

我该怎么做?

推荐答案

也许有更好的解决方案，但您可以尝试

Hi maybe there is better solution but you may try

<% @articles.map(&:id).each do |id| %>
  <%= hidden_field_tag "article_ids[]", id %>
<% end %>
