在HAML中转义内联链接 [英] Unescaping inline links in haml

问题描述

因此，我尝试在电子邮件表单的标题旁获取删除链接.但是，我的rails voodoo显然非常虚弱.它转义了HTML，我不知道如何避免这种情况.有提示吗?

So I'm trying to get a remove link next to the caption in an emails form. However, my rails voodoo is clearly very weak. It escapes the HTML and I can't figure out how to get it to not. Any hints?

= f.input :email, :label => "Email " + link_to_remove_fields("[x]", f)

[edit]哦，是的，这也做同样的事情:

[edit] oh and yes, this does the same thing:

= f.input :email, :label => "Email #{link_to_remove_fields("[x]", f)}"

这是我的助手方法...

and here's my helper method...

def link_to_add_fields(name, f, association)
    new_object = f.object.class.reflect_on_association(association).klass.new
    fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder|
      render(association.to_s.singularize + "_fields", :f => builder)
    end
    link_to_function(name, "add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")")
  end

推荐答案

我遇到了与此相同的问题，我通过在帮助器中使用以下命令解决了该问题:

I had the same issue as this, I fixed it by using the following in my helper:

link_to_function(name, "add_fields(this, '#{association}', \'#{escape_javascript(fields)}\')")

需要注意的一件事是，当我在Rails 3.1应用程序中尝试此操作时，必须先重新启动服务器，然后再获取帮助程序中的更改.对于早期版本，这可能是正确的，也可能不是正确的，但请记住.

One thing to note, when I tried this in a Rails 3.1 app I had to restart the server before changes in the helper were picked up. This may or may not be true for earlier versions but worth keeping in mind.
