如何在资产管道中包括ActionView帮助器? [英] How to include ActionView helpers in the assets pipeline?

问题描述

如何在资产管道执行上下文中包括可使用的Rails视图助手?

How to include Rails view helpers to be accesible by assets pipeline execution context?

一个示例用例是使用form_tag辅助方法为表单生成标记，并将其提供给Javascript模板(如把手，jst等)使用.

An example use case would be to generate the markup for a form, using form_tag helper method, and make it available to a Javascript template (like handlebars, jst, etc.).

我使用handlebar_assets gem，但这也应适用于任何erb或haml模板.

I use handlebar_assets gem, but this should apply to any erb or haml template too.

推荐答案

创建一个初始化程序，并在资产的上下文中包含帮助程序，如下所示:

Create a inititializer and include the helpers in the context of the assets like this:

Rails.application.assets.context_class.class_eval do
  include ActionView::Helpers
  include MyAppHelper
  include Rails.application.routes.url_helpers
end
