accep_nested_attributes_for not save children表

连接users和companies使用accepts_nested_attributes_for。当您添加用户并保存时，公司信息不会被保存。有没有人有任何想法可能是什么问题？提前致谢。accep_nested_attributes_for not save children表

user.rb

class User < ActiveRecord::Base 
    before_create :create_role 
    devise :database_authenticatable, :registerable, :confirmable, 
     :recoverable, :rememberable, :trackable, :validatable 

    attr_accessible :email, :password, :password_confirmation, :remember_me, :role_ids, :company_attributes 

    has_one :company, :autosave => true 

    accepts_nested_attributes_for :company 

    has_and_belongs_to_many :roles 


    def role?(role_name) 
    return !!self.roles.find_by_name(role_name) 
    end 

    def with_company 
    self.company.build 
    self 
    end 

    private 
    def create_role 
     self.roles << Role.find_by_name(:user) 
    end

你能后从检查PARAMS输出，当他们进入控制器？ –

输出：https：//gist.github.com/3863459 – Nar

它看起来像你getti ，NG堵塞质量，分配的保护，尽管在你的模型attr_accessible :company_attributes ...

相关日志输出：

WARNING: Can't mass-assign protected attributes: companies

是从您的代码直接复制/粘贴，或者它可能是拼写错误，或者什么，在真实的代码？

或者它可能需要attr_accessible：companies_attributes ... –

我已更改为：company_attributes但不起作用 – Nar

尝试fields_for：company –

添加：company_attributes在乌尔用户模型attr_accessible

添加在用户模式

def build_company(params = {}) 
    self.company = Company.new(params) 
end 

def company_attributes=(attributes) 
    self.company = Company.new(attributes) 
end
