Rails的accepts

本文介绍了Rails的accepts_nested_attributes_for错误，请帮我发现它的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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...
