问题描述
我一直在努力遵循活动记录嵌套属性指南,但没有成功。
I have been trying to follow the Active Record Nested Attributes Guide, without much success.
我有以下型号:
class Contact < ActiveRecord::Base has_many :telephones accepts_nested_attributes_for :telephones end class Telephone < ActiveRecord::Base belongs_to :contact end在试图创建一个联系人:
When trying to create a contact:
contact = { :name => "John", :telephones => [ {:telephone => '787445741'}, {:telephone => '478589658'} ] } Contact.create(contact)
我收到以下错误: 的ActiveRecord :: AssociationTypeMismatch:电话(#80827590)预计,得到了哈希(#72886250)
I get the following error: ActiveRecord::AssociationTypeMismatch: Telephone(#80827590) expected, got Hash(#72886250)
能否请你帮我找到这个错误? 有没有code,我应该包括在 contact_controller.rb ?
Could you please help me spot the error? Is there any code that I should include in the contact_controller.rb?
推荐答案我得到了它具有以下code工作:
I got it working with the following code:
params = { :contact => { :name => 'Joe', :permanentcomment => "No Comment", :telephones_attributes => [ {:telephone => '787445741'}, {:telephone => '478589658'} ] }} Contact.create(params[:contact])
我经过了错误的参数给 Contact.create 控制器...
