如何在Rails的确认电子邮件中的选项哈希内传递额外的参数？ [英] How to pass extra params inside option hash in confirmation email in Rails?

问题描述

我正在尝试在确认电子邮件中的options {}哈希内传递额外的参数，但这只是向我显示主题和邮件标题中的内容。
这是我的代码

I am trying to pass extra params inside the options{} hash in the confirmation email but It is just showing me subject and from headers in the mailer. This is my code

CustomMailer.confirmation_instructions(user,token, {custom_param: "abc"})

当我在这样的模板中显示opts数据时

When I show opts data inside template like this

@first_name = opts

它显示

{:subject=>"Email Confirmation", :from=>"[e-mail]"}

自定义邮件代码是

class CustomMailer < Devise::Mailer
  helper :application # gives access to all helpers defined within `application_helper`.
  include Devise::Controllers::UrlHelpers # Optional. eg. `confirmation_url`
  #include ApplicationHelper
  default template_path: 'devise/mailer' # to make sure that you mailer uses the devise views

  def confirmation_instructions(record, token, opts={})
    opts[:subject] = "Email Confirmation"
    opts[:from] = '[e-mail]'

    if(record["admin"]==false)
        @template_type = 'donor'
        @first_name = opts

    end
end

为什么不起作用？

推荐答案

不是完整的答案，但评论部分让我很烦，请尝试：

Not a complete answer but the comments section was annoying me, try:

def confirmation_instructions(record, token, opts={})
  @opts = opts
  opts[:subject] = "Email Confirmation"
  opts[:from] = '[e-mail]'

  if(record["admin"]==false)
    @template_type = 'donor'
    @first_name = opts
  end
end

然后在您的邮件中e调用@first_name，然后调用@opts，它应该为您提供输入到方法调用中的参数。

Then in your mailer, where you were calling @first_name, call @opts and it should give you the argument you feed into the method call.
