我正在使用Rails 4.2和Devise 3.5并尝试使嵌套属性正常工作（我已经浏览了多个帖子但仍然无法修复它。）
实际上，我有一个潜在客户模型和一个预订模型（潜在客户可以有多个预订）。
模型
/lead.rb
class Lead < ActiveRecord::Base
has_many :bookings, autosave: true
accepts_nested_attributes_for :bookings
..
/booking.rb
class Booking < ActiveRecord::Base
belongs_to :lead
belongs_to :agent
..
控制器（非常确定这是错误的）
class MyDevise::RegistrationsController < Devise::RegistrationsController
def new
build_resource({})
resource.bookings.build
respond_with self.resource
end
end
before_action :configure_permitted_parameters, if: :devise_controller?
protected
def configure_permitted_parameters
devise_parameter_sanitizer.for(:sign_up) { |u|
u.permit(:email, :password, :first_name, :last_name, :phone_number, :birthday, [bookings_attributes: [:unit_type, :book_date, :agent_id]])
}
end

答案 0 :(得分：0)
您的表单发送参数的方式是仅向用户附加1次预订，而不是“很多”，这是您的预订达到设计的方式：
"booking"=>{"book_date"=>"2016-02-11T09:15:00+00:00", "unit_type"=>"Two Bedroom", "agent_id"=>"1"}
这是因为在您的表单中您使用的是单数符号：
#note you are using :booking instead of :bookings that's why in your params it outputs "booking" instead of "booking_attributes"
<%= f.fields_for :booking do |booking_form| %>
<%= booking_form.hidden_field :book_date, :value => time_helper %>
<%= booking_form.hidden_field :unit_type, :value => session[:unit_type] %>
<%= booking_form.hidden_field :agent_id, :value => 1 %>
<% end %>
如果您只想附上1张预订，请使用以下内容：
before_action :configure_permitted_parameters #,if: :devise_controller? I think that if: is unnecesary.
protected
def configure_permitted_parameters
devise_parameter_sanitizer.for(:sign_up) { |u|
u.permit(:email, :password, :first_name, :last_name, :phone_number, :birthday, booking: [:unit_type, :book_date, :agent_id])
}
end
然后，如果您想允许多个预订，请在<%= f.fields_for :bookings do |booking_form| %>
然后您可以在permit语句中使用booking_attributes: []。

有趣的是 - 似乎错误出现在我的预订模型中，我在验证lead_id，存在：是的。删除此功能可解决此问题。感谢大家的帮助！
