Question

我正在尝试在Rails 4应用程序中创建两个自定义rake任务。他们应该读取agent_card表并根据逻辑，在触发时间时触发电子邮件。这是我第一次创建rake任务而且我没有收到错误，因此我不知道我是否正确行事。我会假设在使用邮件时，一旦邮件被解雇，开信刀就会起作用（如果一切正常），但我不确定。我在下面发布了所有相关代码。提前谢谢！

.rake file

namespace :agent_cards do
   desc 'Sends an email to an agent with a license expiring 2 months from today'
   task license_expire_agent: :environment do
      Rails.logger.info "Mailer Method #{ActionMailer::Base.delivery_method}"
      AgentCard.all.each do |agent_card|
         if agent_card.real_estate_license_expires_at == Date.today + 2.months
            LicenseExpireMailer.license_expire_agent(@agent_card, @agent).deliver_later
         end
      end
   end
end

namespace :agent_cards do
   desc 'Sends an email to an the agent development manager when a license expires 1 week from today'
   task license_expire_mgr: :environment do
      Rails.logger.info "Mailer Method #{ActionMailer::Base.delivery_method}"
      AgentCard.all.each do |agent_card|
         if agent_card.real_estate_license_expires_at == Date.today + 7
            LicenseExpireMailer.license_expire_mgr(@agent_card, @agent).deliver_later
         end
      end
   end
end

license_expire_agent_mailer.rb

class LicenseExpireMailer < ActionMailer::Base
   default from: "Mike <help@mike.com>"

   def license_expire_agent(agent, agent_card)
      @agent = agent
      @agent_card = agent_card
      mail to: "mike@mike.com", subject: 'Your license is about to expire!'
   end
 end

license_expire_mgr_mailer.rb

class LicenseExpireMailer < ActionMailer::Base
   default from: "Mike <help@mike.com>"

   def license_expire_mgr(agent, agent_card)
      @agent = agent
      @agent_card = agent_card
      # Head of Agent Development
      mail to: "mike@mike.com", subject: "#{@agent.name}'s License Expiring"
   end
end

当我尝试测试rake任务时，我输入

rake agent_cards:license_expire_agent

or

rake agent_cards:license_expire_mgr

错误

Answer 1

根据Rails约定，您的邮件程序文件名与邮件程序类名称不匹配。

Mailer类应该放在这条路径中：

app/mailers/license_expire_mailer.rb

ActionMailer w / Custom Rake Task
