升級到state_machines時驗證問題gem

我想從state_machine更改爲state_machines。當我開始這樣做時，我遇到了國家不再從初始狀態改變。升級到state_machines時驗證問題gem

回顧了一些計算器和其他指南： -

https://teamtreehouse.com/community/statemachines-usage
狀態機/ state_machines-的ActiveRecord＃33
Validation before persistance on state_machine gem

因此改變我已經做：

使用狀態機，ActiveRecord的寶石
加DEF初始化... （見下文）
我現在對我的數據得到一個耙子設置錯誤。它似乎與驗證聯繫人（首先創建一個相關的模型）有問題。無論狀態如何，聯繫人總是首先創建。這在改變寶石之前運行良好。

有什麼想法嗎？我想我已經包含了所有相關的代碼。

偕文件：

ruby "2.2.2" 
gem "rails", "4.2.1" 
gem "pg", "0.17.1" # postgresql database 
gem "state_machines-activerecord"

寶石鎖文件

state_machines (0.4.0) 
state_machines-activemodel (0.3.0) 
    activemodel (~> 4.1) 
    state_machines (>= 0.4.0) 
state_machines-activerecord (0.3.0) 
    activerecord (~> 4.1) 
    state_machines-activemodel (>= 0.3.0)`

lead.rb（模型）是：

`class Lead < ActiveRecord::Base 
    belongs_to :created_by_user, class_name: "User", inverse_of: :leads_created 
    belongs_to :contact 
    belongs_to :user 
    accepts_nested_attributes_for :contact 
    validates :contact, presence: true 
state_machine :state, initial: :new_lead do 
    state :claimed 
    state :referred 
    state :broadcast 
    state :unclaimed` 

    `event :claim! do 
     transition all => :claimed 
    end 

    event :unclaim! do 
     transition claimed: :unclaimed 
    end 

    event :refer! do 
     transition new_lead: :referred 
    end 

    event :broadcast! do 
     transition all => :broadcast 
    end` 



`def initialize(*) 
    super() # NOTE: This *must* be called, otherwise states won't get 
    initialized 
    end`

CONTROLLER

def lead_attributes 
    params.require(:lead).permit( :claimed, 
     :contact_id, 
     :status, 
     :state, 
     :user_id

setup_acceptance.rake

def create_contact(options={}) 
    user    = User.find_by(last_name: "Smith") 
    contact_attributes = { created_by_user: user, user: user } 
    attributes   = contact_attributes.merge options 
    contact = Contact.create! attributes 
    contact.save! 
    contact 
end 
def create_lead(options={}) 
    user    = User.find_by(last_name: "Smith") 
    client_attributes = { user: user, created_by_user: user } 
    attributes  = client_attributes.merge options 
    Lead.create! attributes ****(LINE 1311 where error message occurs)**** 
end

rake.setup

Lead.transaction do #(NOTE: THIS IS LINE 435) 
    create_lead( #(NOTE: THIS IS LINE 436) 
     user: User.find_by(last_name: "Smith"), 
     contact: Contact.find_by(last_name: "Lozar"), 
     status: 0, 
     state: "claimed" 
     } 
     ] 
    )

錯誤：

非常感謝@avdi

解決的辦法是改變：

super()

...它丟棄所有的初始化參數

到：

super

...含蓄地保留他們。
