我有一個agent模型和agent_card模型。一旦有人正在僱用代理卡，爲他們創建。我試圖讓一個郵件發送一次該人被僱用，但不知道爲什麼它不工作。任何幫助表示讚賞。問題Rails梅勒沒有射擊

代理控制器 - 採用方法：

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: "[email protected]" 

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

    mail(:to => "[email protected]", :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") %>

在視圖中，我沒有打電話給代理。

它需要的是：一個星期六... amirite

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

編程？
