ActionMailer将局部变量传递到erb模板 [英] ActionMailer pass local variables to the erb template

问题描述

我知道我可以定义实例变量，例如:

I know I could define instance variables e.g:

def user_register(username, email)
  @username = username
  @email = email

  mail(:to => email, :subject => "Welcome!", :template_name => "reg_#{I18n.locale}")
end

但是，有没有办法使用 local 变量，就像将:locals 传递给partials一样?

But, is there a way to use local variables instead, just like passing :locals to partials?

推荐答案

mail方法中可用的所有选项都可以在

All options available in the mail method can be found at http://api.rubyonrails.org/classes/ActionMailer/Base.html#method-i-mail.

我们知道render具有:locals选项.但是，我们可以看到mail没有可用的:locals选项.因此，没有，没有比使用实例变量更好的方法了(除非您想使用诸如全局变量或持久数据库对象之类的丑陋的东西-不要这样做).

We know that render has a :locals option. However we can see that there is no :locals option available for mail. Therefore, no, there is no better way than to use instance variables (unless you want to use something hideous like globals or persistent database objects - don't do this).

实例变量就是您要使用的.

Instance variables are what you are meant to use.
