Ruby on rails 4 Sidekiq+；设计具有多个子域的邮件程序

在我的一个项目中，在运行时更改ActionMailer:：Base.default_url_options={:host=>host}时遇到问题

设置： 我有多个子域，它们在后端使用相同的Rails应用程序。我想通过Sidekiq队列向用户发送我的设计邮件。设计邮件（确认、重置密码）包含链接，这些链接需要特定子域才能正确

我的环境

rails (4.2.0)
sidekiq (3.3.1)
devise (3.4.1)
devise-async (0.9.0)

我的应用程序\u控制器中有一个before\u操作

class ApplicationController < ActionController::Base

  before_action :set_action_mailer_default_url_options

  private

  def set_action_mailer_default_url_options
    host = "my-logic-to-get-the-correct-host"
    ActionMailer::Base.default_url_options = {:host => host}
  end

end

主机始终在控制器中设置正确。我已经调试过了。似乎主机没有传递给sidekiq。。你知道我该怎么解决这个问题吗

我无法将子域保存在某个地方，因为用户可以触发来自不同子域的电子邮件，但并不总是相同的。我需要一种方法来告诉Desive应该使用哪个主机来发送特定的电子邮件。我可以覆盖设计邮件器并传递主机或类似的东西吗

以下解决方案在我的情况下是不可能的：

顺便说一句：完整的工作流程与设计，设计异步和sidekiq本身的工作（在开发，分期和生产）。只有链接的主机不正确->这是我的大问题：-）…

您可以在应用程序控制器中覆盖默认url选项，如下所示：

class ApplicationControllerhost}
结束
结束

或者您可以尝试以下答案：

我最终得到了以下解决方案。此解决方案包含这样的情况：您有多个客户，这些客户可以拥有自己的电子邮件设置以及邮件中URL的自己的域/子域

我使用了自己的mailer类，并连接到客户可能的自定义电子邮件设置中：

config/initializers/designe.rb：

config.mailer = "DeviseMailer"

config/secrets.yml：

development:
  mailer_settings:
    customers:
      customer_1_identifier_name:
        send:
          address: "smtp.gmail.com"
          port: 587
          domain: "example"
          user_name: "test@example.com"
          email: "noreply@example.com"
          password: "secret"
          authentication: "plain" # or "login"
          ssl: false # or true
          tls: false # or true
          enable_starttls_auto: true # or false

app/mailers/designe_mailer.rb：

class DeviseMailer < Devise::Mailer
  layout 'mailer'

  after_action :set_email_settings_and_sender, only: [:reset_password_instructions, :confirmation_instructions]

  def reset_password_instructions(record, token, opts={})
    @account = record.current_account if record.class == User # set the account of current_user - current_account is an own helper method
    super
  end

  def confirmation_instructions(record, token, opts={})
    @account = record.current_account if record.class == User && record.unconfirmed_email.present?
    super
  end

  private

    # re-set the email settings for the given user and his account:
    def set_email_settings_and_sender
      if @account.present? && @account.custom_email_settings?
        mail.reply_to = nil
        settings = Rails.application.secrets.mailer_settings["customers"][@account.identifier_name]["send"].symbolize_keys
        mail.delivery_method.settings.merge!(settings)
        mail.from = "#{@account.display_name} <#{settings[:email]}>"
      end
    end

end
