验证错误消息未设置相关的记录

Question

比方说，我们有以下方面：

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 

我怎样才能让验证错误设置为相关记录和不将拥有记录？这使得嵌套表单更加复杂，因为这些表单重用部分更加困难。

我确实需要有：

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

显然它的工作如预期。只是在我的代码中遇到困难让我觉得它没有。现在感到惭愧......
