Question

我创建了两个邮件程序，其中一个不在Heroku上进行生产。另一个邮件已经过测试并且可以正常运行，所以我知道sendgrid的电子邮件配置正在运行。

我有一个邀请模型：

class Invitation < ActiveRecord::Base
  attr_accessible :recipient_email, :sender_id, :sent_at, :token
  belongs_to :sender, :class_name => 'User'
  has_one :recipient, :class_name => 'User'
  validates_presence_of :recipient_email
  validate :recipient_is_not_registered
  validate :sender_has_invitations, :if => :sender

  before_create :generate_token
  before_create :decrement_sender_count, :if => :sender 
  after_create do |invitation|
  Mailer.delay.deliver_invitation(invitation)
  end

  private

  def recipient_is_not_registered
    errors.add :recipient_email, 'is already registered' if User.find_by_email(recipient_email)
  end

  def sender_has_invitations
    unless sender.invitation_limit > 0
      errors.add_to_base 'You have reached your limit of invitations to send.'
    end
  end

  def generate_token
    self.token = Digest::SHA1.hexdigest([Time.now, rand].join)
  end

  def decrement_sender_count
    sender.decrement! :invitation_limit
  end
end

梅勒：

class Mailer < ActionMailer::Base
  helper ActionView::Helpers::UrlHelper
 default from: "noreply@lumeo.com"

 def invitation(invite)
   @invitation = invite

   mail to: invitation.recipient_email, subject: "Invitaiton"
 end
end

文本文件：

You are invited to join our beta!
<%= link_to 'Sign Up', signup_url(@invite.token) %>

观点：

<div class="breadcrumbs span12 row">
    <p>
        <%= link_to "contests", contests_path %> > send invitation
    </p>
</div>
<div class="span12">
    <div class = "span6 offset2 pull-left">
        <div class="title">
            <h1>Invite Friends</h1>
        </div>
        <%= simple_form_for @invitation do |f| %>
            <fieldset class="edit well">
                <p></p>
                <p><%= f.input :recipient_email, :label => "Friend's email address" %></p>
            </fieldset>
            <div class="form-actions">
                  <%= f.submit 'Send Invite', :class => 'btn btn-primary pull-right btn-large m5' %>
            </div>
        <% end %>
    </div>
    <div class = "well pull-right span2">
        <% if current_user.invitation_limit > 0 %>
        <p>
            Welcome <%= current_user.name %>, 
            you have <%= current_user.invitation_limit %> invitations left</p>
        <% else %>
        <% end %>
    </div>

</div>

以下是heroku的日志文件：

问题的答案可能对其他人有帮助，也可能没有帮助。我定义了两个邮件程序类，一个在mailers / mailer.rb中，另一个在models / mailer中.rb

Rails 2.0没有使用邮件程序目录，显然我一直关注两个不同的来源，以获取有关如何设置它的信息。有可能其他人会遇到同样的问题。我删除了models / mailer.rb文件
