Rails和Gmail-回复功能无法正常工作

问题1

我用同一个gmail帐户发送邮件,就像我用它接收邮件一样,因此当我点击“回复”按钮时,gmail会给我自己设置一个新的邮件。。。。

class Notification < ActionMailer::Base

  default :to => ENV['GMAIL_USER']

  def hello(contact)    
   mail(
    :from => contact[:email],
    :return_path => contact[:email],
    :subject => "[My Website] << #{contact[:subject]}", 
    :body => contact[:body] )
  end
end

我当时的印象是 :return_path => contact[:email] 会确保gmail知道该给谁发送回复。。。。显然我错了。有人知道怎么解决这个问题吗?

大多数的action\u mailer教程都会让我使用 :from => contact.email :from => contact[:email] 就像这样:

  def hello(contact)
      @contact = contact    
      mail(
           :from => contact.email,
           :return_path => contact.email,
           :subject => "[My Website] << #{contact.subject}",
           :body => contact.body
           )
  end

但当我这样做时,会收到以下错误消息:

undefined method `email' for #<ActiveSupport::HashWithIndifferentAccess:0xdde82f0>

FWIW,如果有帮助的话,我的contact模型扩展了一个tables active_record模型,因为我不想使用该数据库,但希望有有效性,所以它看起来像这样:

#contact.rb
class Contact < Tabless
  column :name,          :string
  column :email,         :string
  column :body,          :text
  column :subject,       :string      
  # validations go here
end

# tabless.rb
class Tabless < ActiveRecord::Base

  # create an array of columns
  def self.columns()
    @columns ||= [];
  end

  # add new column to columns array
  def self.column(name, sql_type = nil, default = nil, null = true)
    columns << ActiveRecord::ConnectionAdapters::Column.new(name.to_s,
    default,
    sql_type.to_s,
    null)
  end

  # override the save method to prevent exceptions
  def save(validate = true)
    validate ? valid? : true
  end
end
