Rails Mailer無法啟動的問題

Question

我有一個agent模型和一個agent_card模型。 一旦有人雇用，便為他們創建了代理卡。 一旦該人被錄用，我試圖讓郵件發送，但是不確定為什么它不起作用。 任何幫助表示贊賞。

代理人控制器-用人方法：

def employ
  @agent.employee = true
  @agent.on_probation = true
  @agent.save(validate: false)
  AgentCard.create(agent_id: @agent.id, hire_date: Date.current)
  AgentCardMailer.agent_card_message(@agent_card, @agent).deliver_later
  respond_to do |format|
    format.html { redirect_to :back }
    format.json { head :no_content }
  end
end

agent_card_mailer.rb：

class AgentCardMailer < ActionMailer::Base
  default from: "help@mail.com"

  def agent_card_message(agent_card, agent)
    @agent_card = agent_card
    @agent = agent

    mail(:to => "mike@mail.com", :subject => "New Agent Card Created!")
  end
end

agent_card.html.erb：

Hiya Mike,<br><br>

A new Agent Card has been created!<br><br><br>

Name: <%= @agent_card.agent.name %><br><br>
Date Created: <%= @agent_card.created_at.strftime("%m/%d/%Y @ %l:%M %p") %>

在我看來，我沒有打電話給代理商。

它必須是：

Name: <%= @agent.agent_card.agent.name %><br><br>
Date Created: <%= @agent.agent_card.created_at.strftime("%m/%d/%Y @ %l:%M %p") %>
