Ruby on rails RailsAdmin NoMethodError在RailsAdmin:：Main#delete中

我有订购的型号：

class Order < ActiveRecord::Base
  has_one :shipping_address
  has_and_belongs_to_many :books

  validates :first_name, :surename, :email, :street1, :country, :zipcode, presence: true
  validates_format_of :email, :with => /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\z/i
  validates :zipcode, numericality: true

  accepts_nested_attributes_for :shipping_address
end

您是否在代码中的任何地方定义了“orders\u books”方法？如果是的话，请你把它添加到你的问题中。如果没有，那么问题的根本原因就是，您正在调用“orders\u books”方法，但它尚未定义

---

考虑到您在问题中引用了“图书订单”，我相信您可能只是在代码中的某个点交换了“图书订单”和“图书订单”

谢谢。这是Rails 4.1.1的bug。我已将其更新为4.1.4，一切正常。

它肯定在尝试调用该方法，所以请再看一看。谢谢。这是Rails 4.1.1的bug。我已将其更新为4.1.4，所有工作正常。

class Book < ActiveRecord::Base

  DEFAULT_PRICE = 55.15
  NEXT_BOOK_PERCENT = 5

  has_and_belongs_to_many :pages
  has_and_belongs_to_many :orders

  validates :name, presence: {message: "Name can't be blank."}
  validates_length_of :name, minimum: 3, maximum: 12, message: "Sorry, we can't create             this book right now. Please contact us for further information."

  validate :same_letter_validation
  validate :validates_for_non_alphabetic
