【问题描述】：

我创建了一个表单，提交后会发送一封电子邮件，其中包含已填写的表单内容。有时邮件会发送，有时不会，这是为什么呢？

notifcations_mailer.rb 

class NotificationsMailer < ActionMailer::Base
  default :from => "smile@tlcdentalsyr.com"
  default :to => "smile@tlcdentalsyr.com"

  def new_message(message)
    @message = message
    mail(:subject => "Appointment for #{message.date}")
  end
end

contact_controller.rb

class ContactController < ApplicationController

def new
  @message = Message.new
end

def create
  @message = Message.new(params[:message])

  if @message.valid?
    NotificationsMailer.new_message(@message).deliver
    redirect_to(contact_path, :notice => "Message was successfully sent.")
  else
    flash.now.alert = "Please fill all fields."
    redirect_to :back
  end
 end
end

message.rb:

class Message

 include ActiveModel::Validations
 include ActiveModel::Conversion
 extend ActiveModel::Naming

 attr_accessor :name, :currentpatient, :email, :phone, :calltime, :date, :apttime,  :treatment, :subject

 validates :name, :currentpatient, :phone, :calltime, :date, :apttime, :treatment, :presence => true
 validates_format_of :email, :with => /.+@.+\..+/i

 def initialize(attributes = {})
   attributes.each do |name, value|
     send("#{name}=", value)
 end
end

def persisted?
  false
end
end

应用程序.rb：

config.action_mailer.smtp_settings = {
  :address              => "smtpout.secureserver.net",
  :port                 => 80,
  :domain               => "domain.com",
  :user_name            => "email@domain.com",
  :password             => "mypass",
  :authentication       => :plain,
  :enable_starttls_auto => true
}

config.action_mailer.default_url_options = {
  :host => "domain.com"
}

【解决方案1】：

您缺少配置，请查看下面的 production.rb 文件配置

#default url for mailer
config.action_mailer.default_url_options = { :host => 'domainname' }
config.action_mailer.delivery_method = :smtp
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = false
config.action_mailer.default :charset => "utf-8"

config.action_mailer.smtp_settings = {
 :enable_starttls_auto => false,
 :address => "smtp.emailsrvr.com",
 :port => 587,
 :domain => "domainname",
 :authentication => :login,
 :user_name => 'smtp@domainname.com',
 :password => 'password',
}

编码愉快。！！
