Ruby on rails 如何为具有一个关系的模型强允许参数

我有以下联系

用户有一个配置文件

配置文件有许多图像

在创建用户时，我希望一次性更新配置文件和图像

class User < ApplicationRecord
  has_one :profile
  accepts_nested_attributes_for :profile
end

class Profile < ApplicationRecord
  belongs_to :user
  has_many :images
  accepts_nested_attributes_for :images
end
class Image < ApplicationRecord
  belongs_to :profile
end

输出是这样的

Started POST "/create_user" for 127.0.0.1 at 2017-05-04 18:55:01 +0530
  ActiveRecord::SchemaMigration Load (0.1ms)  SELECT "schema_migrations".* FROM "schema_migrations"
Processing by UsersController#create as */*
  Parameters: {"user"=>{"name"=>"vamsi", "profile_attributes"=>{"address"=>"my home address", "images_attributes"=>{"0"=>{"image_url"=>"url1"}, "1"=>{"image_url"=>"url2"}}}}}
   (0.1ms)  begin transaction
   (0.1ms)  rollback transaction

下面是一个示例应用程序，它设置了上述关联

您能否通过调试

@user.errors.messages

{：“profile.user”=>[“必须存在”]，：“profile.images.profile”=>[“必须存在”]}来检查错误是什么这就是我得到的感觉，问题是你在配置文件模型中的

user\u id

和图像模型中的

profile\u id

上有状态验证，但是rails在保存用户和配置文件模型之前尝试验证这些字段我没有任何类似的验证，无论我有什么代码，都是我在那里以及github repo中提到的

{
    "user": {
        "name": "vamsi",
        "profile_attributes": {

              "address": "my home address",

            "images_attributes": {
                "0": {
                    "image_url": "url1"
                },
                "1": {
                    "image_url": "url2"
                }
            }
        }
    }
}
