Question

我正在使用ActionMailer 4.0.0开发Ruby on Rails 4.0.0。尽管遵循Rails指南，我仍然无法发送电子邮件，也无法成功测试。从rails控制台检查ActionMailer实例我正在观察正在实例化的NullMailer，它（什么都不做）TM

>> rails c
Loading development environment (Rails 4.0.0)
2.0.0p247 :001 > er = EventRegistration.last
2.0.0p247 :003 > MainMailer.event_registration(er)
=> #<ActionMailer::Base::NullMail:0x007fc11cbe3108>

我对Rails指南以及ActionMailer代码库中的注释进行了双重检查。这是我的文件：

的Gemfile：

source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '= 4.0.0'

# Use SCSS for stylesheets

gem 'quiet_assets', group: [:development, :test]
gem "guard-rails", group: :development

在config/environments/test.rb我有：

# Tell Action Mailer not to deliver emails to the real world.
# The :test delivery method accumulates sent emails in the
# ActionMailer::Base.deliveries array.
config.action_mailer.delivery_method = :test

我的EventRegistration型号：

class EventRegistration < ActiveRecord::Base
  validates_presence_of :first_name, :last_name, :email, :event_id
  validates_format_of :email,
    :with => /\A[^\s@]+@[^\s@]+\.[^\s@]+\z/,
    :message => "was not well-formed"
  belongs_to :event

  def send_notifications
    EventMailer.event_registration(self).deliver
    EventMailer.event_confirmation(self).deliver
  end
end

EventRegistration的规范：

require 'spec_helper'

describe EventRegistration do
  let(:event) { 
    NormalEvent.create({
      "name"=>"Whats up Doc?",
      "type_of_event"=>"Cartoon",
      "presented_by"=>"Looney Tunes",
      "speakers"=>"Donald Duck",
      "duration"=>"30 minutes",
      "status_id"=>"100",
      "allow_registration"=>"1",
      "starts_on(1i)"=>"2015",
      "starts_on(2i)"=>"3",
      "starts_on(3i)"=>"11",
      "start_time"=>"06:35",
      "end_time"=>"07:00",
      "hide_date"=>"0",
      "summary"=>"Not much",
      "details"=>"<p>Cartoon with the wabbit in it.</p>"
    })
  }

  let(:registration) {
    EventRegistration.create({
      "first_name"=>"Bugs",
      "title"=>"Wabbit",
      "address1"=>"123 Nowhere St",
      "city"=>"Anyville",
      "postal_code"=>"12345",
      "email"=>"bugs.bunny@looneytunes.com",
      "last_name"=>"Bunny",
      "company_name"=>"Looney Tunes",
      "state"=>"GA",
      "country"=>"USA",
      "phone"=>"555-555-1234",
      "event_id" => event.id}
    })
  }

  it "should initialize" do
    assert_equal true, event.valid?
    assert_equal true, registration.valid?
  end

  it "should send notifications" do
    registration.send_notifications
    assert !ActionMailer::Base.deliveries.empty?
  end
end

assert !ActionMailer::Base.deliveries.empty?行失败

为什么NullMailer会被实例化而不是TestMailer的任何想法？为了它的价值，即使已经配置了SMTP设置，NullMailer也会被实例化用于生产。

Answer 1

您未在MainMailer#event_registration中致电ActionMailer::Base#mail。

ActionMailer没有实例化正确的邮件程序类
