Question

我正在关注StackOverflow帖子中引用的教程，以获取简单的联系表单。教程在这里：http://matharvard.ca/posts/2011/aug/22/contact-form-in-rails-3/

所有内容都是复制/粘贴，并为我的域名和邮件设置更改了一些值。遇到两个非常奇怪的错误：当我第一次提交联系表格时，我得到了一个：

  堆栈级别太深

Rails.root：/ Users / me / application

应用程序跟踪|框架跟踪|完整跟踪

加载以下文件时发生此错误：

邮件

邮件/解析器/ rfc2822_obsolete

如果我重新提交而不重启rails应用程序，我会得到：

未初始化的常量Mail :: Ruby19

Rails.root：/ Users / me / application

应用程序跟踪|框架跟踪|完整跟踪

app / mailers / notifications_mailer.rb：1：在`'

app / controllers / contact_controller.rb：11：在'create'

加载以下文件时发生此错误：

邮件

我认为可能相关的部分是：

class NotificationsMailer < ActionMailer::Base
  default :from => "feedback@mydomain.com"
  default :to => "me@gmail.com"

  def new_message(message)
    @message = message
    mail(:subject => "mydomain Feedback")
  end
end

class Message
  include ActiveModel::Validations
  include ActiveModel::Conversion
  extend ActiveModel::Naming

  attr_accessor :name, :email, :subject, :body

  validates :name, :email, :subject, :body, :presence => true
  validates :email, :format => { :with => %r{.+@.+\..+} }, :allow_blank => true

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

  def persisted?
    false
  end
end

class ContactController < ApplicationController
  def new
    @message = Message.new
  end

  def create
    @message = Message.new(params[:message])        
    if @message.valid?
        NotificationsMailer.deliver_new_message params[:message]
      # NotificationsMailer.new_message(@message).deliver
      redirect_to(root_path, :notice => "Message was successfully sent.")
    else
      flash.now.alert = "Please fill all fields."
      render :new
    end
  end
end

其余模板非常简单，渲染效果很好。

另外，附上gemfile以防我错过了一些明显的冲突：

source 'https://rubygems.org'
gem 'rails', '3.2.8'
gem 'sqlite3'
gem 'redis', '2.1.1'
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'
  gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
gem 'jade'
gem "haml", ">= 3.1.7"
gem "haml-rails", ">= 0.3.5", :group => :development

提前谢谢。

Answer 1

我认为来自ContactController.rb的以下代码是罪魁祸首：

NotificationsMailer.deliver_new_message params[:message]

您实际上没有方法名称deliver_new_message

尝试删除它，并取消注释它下面的行：

NotificationsMailer.new_message(@message).deliver

希望这有帮助
