属性未通过设计和 accepts_nested_attributes_for 保存
Attributes not saving with devise and accepts_nested_attributes_for
我有一个几乎可以使用的 Devise 注册表单。虽然它似乎有效，但它并没有保存我的 Custaddress table 中的字段，而不是 user_id。任何有助于解决如何让它保存其余信息的帮助都会很棒。以下被大大截断了！！
User.rb 包含：
class User < ApplicationRecord
has_one :custaddress
accepts_nested_attributes_for :custaddress
end
托管地址包含：
class Custaddress < ApplicationRecord
has_many :orders
belongs_to :user
end
注册控制器包含：
如您所见，这只是建立在“标准”Devise 控制器之上。这里没有创建或新建，因为我假设它使用的是标准方法。
class Users::RegistrationsController < Devise::RegistrationsController
invisible_captcha only: :create
protected
def build_resource(hash = {})
self.resource = resource_class.new_with_session(hash, session)
resource.build_custaddress
# Jumpstart: Skip email confirmation on registration.
# Require confirmation when user changes their email only
resource.skip_confirmation!
# Registering to accept an invitation should display the invitation on sign up
if params[:invite] && (invite = AccountInvitation.find_by(token: params[:invite]))
@account_invitation = invite
# Build and display account fields in registration form if enabled
elsif Jumpstart.config.register_with_account?
account = resource.owned_accounts.first
account ||= resource.owned_accounts.new
account.account_users.new(user: resource, admin: true)
end
end
def update_resource(resource, params)
# Jumpstart: Allow user to edit their profile without password
resource.update_without_password(params)
end
def sign_up(resource_name, resource)
if cookies[:ordernum]
order = Order.where(ordernum: cookies[:ordernum]).first
if order
order.update!(user: resource, custaddress: resource.custaddress)
cookies.delete "ordernum"
end
end
sign_in(resource_name, resource)
# If user registered through an invitation, automatically accept it after signing in
if params[:invite] && (account_invitation = AccountInvitation.find_by(token: params[:invite]))
account_invitation.accept!(current_user)
# Clear redirect to account invitation since it's already been accepted
stored_location_for(:user)
end
end
end
我的 new.html.erb 包含：
<%= form_with(model: resource, as: resource_name, url: registration_path(resource_name, invite: params[:invite])) do |f| %>
<%= f.fields_for :custaddress do |cust| %>
<div class="form-group">
<%= cust.label "Apartment/Unit Number", class: "font-bold" %>
<%= cust.text_field :apartment, class: "form-control", placeholder: "Unit 2 or Apartment 307" %>
</div>
And much more!

谁能帮我弄清楚为什么保管地址没有保存。我在这上面花了几个小时，并阅读了 google 上的每篇文章（好吧，感觉确实如此）。
我曾尝试追踪此事，但无济于事。
为完整性添加一个答案。
Devise 的 create 操作调用您正在覆盖的 build_resurce 方法。问题是您为 new 操作覆盖了它，但没有考虑 create 操作。
所以，你正在这样做：
def build_resource(hash = {})
self.resource = resource_class.new_with_session(hash, session)
resource.build_custaddress
对于 new 操作没有问题，resource.build_custaddress 将实例化一个新的 custaddress 对象，以便您能够使用 fields_for 助手。
问题是，对于 create 操作，此时 resource 已经有一个 custaddress 具有来自请求的值（由上一行设置），然后你做 resource.build_custaddress 并用一个新的空 custaddress 替换当前的 custaddress。
解决方案是仅在 custaddress 不为 nil 时构建它：
def build_resource(hash = {})
self.resource = resource_class.new_with_session(hash, session)
resource.build_custaddress if resource.custaddress.nil?
这样，您将为 new 操作获得一个新的空保管地址，但要尊重 create、edit 或 update 请求中的值动作。
