ruby-on-rails - 模型订单的未定义方法“aasm_state”您是说什么？aasm_state=

Question

添加Aasm gem后，Rspec-rails 测试开始失败。所有基本设置都已完成。通过添加 aasm_state 列进行迁移。将状态添加到 Order 模型。

测试日志：

Searching book Visitor searches books by title
 Failure/Error: order = Order.create

 ActionView::Template::Error:
   undefined method `aasm_state' for #<Order:0x0000000008e48740>
   Did you mean?  aasm_state=

但是测试中没有订单：

require 'spec_helper'
require 'rails_helper'

feature 'Searching book' do

  before do
    book = Book.create title: "Geralt"
    author = Author.create full_name: "Swiss"
    category = Category.create title: "Programming"
    category.books << book
    book.authors << author
    author.books << book
    visit books_path
  end

  scenario 'Visitor searches books by title' do
    fill_in 'search', with: "Geralt"
    click_button('Search')
    expect(page).to have_content 'Geralt'
  end

end

也许问题出在应用程序控制器辅助方法中：

class ApplicationController < ActionController::Base
  helper_method :current_order
  protect_from_forgery with: :exception

  def current_order
    if session[:order_id].nil?
      order = Order.create
      session[:order_id] = order.id
      order
    else
      Order.find(session[:order_id])
    end
  end

end

带有 aasm 的 Order.rb，部分：

  include AASM
  aasm do
    state :in_progress, initial: true
    state :processing
    state :in_delivery
    state :delivered
    state :canceled
  end

模板：

= form_tag books_path, method: :get do
  .form-group.col-sm-2
    = text_field_tag :search, params[:search], class: "form-control", id: "search",placeholder: "Search book"
  = submit_tag "Search", class: "btn btn-primary"

= render @books

= "Items in cart #{current_order.order_items.count}"
