在RoR中将变量值注入javascript和HAML [英] Injecting variable values into javascript and HAML in RoR

问题描述

我有以下使用ZenDesk的功能。我想将current_user详细信息注入表单，如下所示。 （这是我的html.haml模板）。但是我无法弄清楚如何使这项工作。

I have the following function for using ZenDesk. I'd like to inject my current_user details into the form as follows. (this is my from html.haml template). However I cannot figure out how to make this work.

:javascript
    if (typeof(Zenbox) !== "undefined") {
      Zenbox.init({
        dropboxID:   "xxxxx",
        url:         "xxxxx.zendesk.com",
        tabID:       "support",
        tabColor:    "black",
        tabPosition: "Left",
        requester_name:  =current_user ? "#{current_user.first_name} #{current_user.last_name}" : "" ,
        requester_email: =current_user ? "#{current_user.email}" : "" ,
        hide_tab: true
        });
    }

简而言之，如何将rails变量注入haml中的：javascript元素。

In short, how does one inject rails variables into a :javascript element in haml.

推荐答案

这应该有效。将所有内联ruby放入＃{} ：

This should work ie. put all inline ruby inside of #{}:

requester_name:  "#{current_user.first_name + ' ' + current_user.last_name if current_user}",
requester_email: "#{current_user.email if current_user}",
