驗證錯誤消息未設置相關的記錄

Question

比方說，我們有以下方面：

class Company 
    belongs_to :address, validate: true 
end 

class Address 
    validates :line1, presence: true 
end 

company = Company.new({ ... }) 
company.address = Address.new({ line1: '' }) 

company.save 

puts company.errors[:address] # nothing 
puts company.errors[:"address.line1"] # can't be blank 

我怎樣才能讓驗證錯誤設置爲相關記錄和不將擁有記錄？這使得嵌套表單更加複雜，因爲這些表單重用部分更加困難。

我確實需要有：

puts company.address.errors[:line1] # can't be blank 

Answer 1

custom validation methods

validate :check_address, :on => :create 

def check_address 
    if self.address.line1.blank? 
    errors.add(:line1, "Please fill line 1.") 
    end 
end 

Answer 2

顯然它的工作如預期。只是在我的代碼中遇到困難讓我覺得它沒有。現在感到慚愧......
