我大约有两个月的时间来学习 RoR。

尝试使用https://monospace-rails.herokuapp.com/设置订阅站点，并希望将客户的实际地址字段添加到表单中。出于某种原因，我找不到有关此的任何信息。我可能在搜索错误的关键词。

这是用户模型：

class User < ActiveRecord::Base
  attr_accessible :name, :email, :password, :password_confirmation, :stripe_token, :last_4_digits

  attr_accessor :password, :stripe_token
  before_save :encrypt_password
  before_save :update_stripe

  validates_confirmation_of :password
  validates_presence_of :password, :on => :create

  validates_presence_of :name
  validates_presence_of :email
  validates_uniqueness_of :email
  validates_presence_of :last_4_digits

  def stripe_description
    "#{name}: #{email}"
  end

  def update_stripe
    if stripe_id.nil?
      if !stripe_token.present?
        raise "We're doing something wrong -- this isn't supposed to happen"
      end

      customer = Stripe::Customer.create(
        :email => email,
        :description => stripe_description,
        :card => stripe_token
      )
      self.last_4_digits = customer.active_card.last4
      response = customer.update_subscription({:plan => "premium"})
    else
      customer = Stripe::Customer.retrieve(stripe_id)

      if stripe_token.present?
        customer.card = stripe_token
      end

      # in case they've changed
      customer.email = email
      customer.description = stripe_description

      customer.save

      self.last_4_digits = customer.active_card.last4
    end

    self.stripe_id = customer.id
    self.stripe_token = nil
  end

  def self.authenticate(email, password)
    user = self.find_by_email(email)
    if user && BCrypt::Password.new(user.hashed_password) == password
      user
    else
      nil
    end
  end


  def encrypt_password
    if password.present?
      self.hashed_password = BCrypt::Password.create(password)
    end
  end
end

我假设我需要将地址字段添加到 db、attr_accessible 和 Stripe::Customer.create 中添加一些东西。我对如何编写它以及是否需要让它工作有点困惑。

任何帮助甚至是正确方向的链接都将是巨大的。
