使用动态变量局部渲染轨道 [英] Rendering rails partial with dynamic variables

问题描述

我正在尝试根据用户所在的分类单元来渲染部分内容.在我的application.html.erb布局中，有以下代码行:

I'm trying to render a partial based on the taxon the user is inside. In my application.html.erb layout I have the following line of code:

<%= render 'spree/shared/women_subnav' if @enable_women %>

在分类控制器中，在show方法内，我有:

In the taxons controller, inside the show method, I have:

@taxon_id = params[:id].split('/').first

在分类群中，我有:

<% if @taxon_id == params[:id].split('/').first %>
  <%= "@enable_#{@taxon_id}" = true %>
<% end %>

运行此命令时，出现SyntaxError.但是在分类单元中#show如果我只输入:

When I run this I get a SyntaxError. But in taxons#show If I just enter:

<% if @taxon_id == params[:id].split('/').first %>
  <%= "@enable_#{@taxon_id}" %>
<% end %>

没有'= true'的页面将呈现，输出'@enable_women'.所以我知道它获取了正确的变量，我只需要将该变量设置为true.我想念什么?

without the '= true' then the page renders, outputting '@enable_women'. So I know it's getting the correct variable, I just need that variable to be set to true. What am I missing?

非常感谢.

推荐答案

使用instance_variable_set

instance_variable_set "@enable_#{@taxon_id}", true

仅提醒您，最好在控制器内执行这些操作.

just a reminder that it's better to do these things inside a controller.
