Question

首先，抱歉我的英语不好..

我在这里遇到了一些问题

我有来自视图表格的输出数据

{
code: 'code supplier',
name: 'name supplier',
address: 'address supplier', 
phone_number: 'phone number supplier',
fax: 'fax supplier',
contact_persons: [
  {name: 'contact person 1', value_number: '123456', value_type: 'mobile phone'},
  {name: 'contact person 2', value_number: '123456', value_type: 'mobile phone'},
  {name: 'contact person 3', value_number: '123456', value_type: 'email'},
  {name: 'contact person 4', value_number: '123456', value_type: 'bb'}
  ]
bank_accounts: {
  name: 'hendrik',
  account_number: '1234578',
  bank_name: 'bca',
  branch_name: 'pasirkaliki'
  }
}

我希望使用虚拟属性将它全部保存到关联的表中，我尝试了一些代码

#VIRTUAL ATTRIBUTES
attr_accessor :address, :phone_number, :fax, :contact_person, :bank_account,    :value_number, :value_type, :bank_id, :account_name

# CALLBACKS
before_save :set_extra_attributes

def self.virtual_attributes
  [:address, :phone_number, :fax, :bank_account, :contact_person, :value_number, :value_type, :bank_id, :account_name]
end

def set_extra_attributes
  self.addresses = [Address.new(address: self.address)] if self.address.present?
  self.phone_numbers = [PhoneNumber.new(number: self.phone_number, phone_type: 'phone')] if self.phone_number.present?
  self.phone_numbers = [PhoneNumber.new(number: self.fax, phone_type: 'fax')] if self.fax.present?
  self.bank_accounts = [BankAccount.new(account_number: self.bank_account, holding_company_id: '1', bank_id: self.bank_id.to_i, name: self.account_name)] if self.bank_account.present?

  contact = [name: self.contact_person, value_type: self.value_type, value_number: self.value_number]

  contact.each do |u|
  ContactPerson.new(name: u[:name], value_type: u[:value_type], value_number: u[:value_number])
  end
end

我使用Postgre，我完全不确定上面的代码，因为它将每一列（例如self.value_type）设置为虚拟属性并且效率不高，任何方式只将bank_account和contact_person设置为虚拟属性和其他列（例如self.value_type）只是像contact_person [：value_type]那样设置哈希，我试过这个但仍然遇到一些问题，怎么做？或者你们有另一种解决问题的好方法，我真的很感激，谢谢

rails 4 params on hash并将其保存到具有虚拟属性的db中
