Rails的嵌套属性与

我用Rails 4.2和3.5制定并试图获得嵌套属性的工作设计（注册表格）（我已经通过多个职位消失了，似乎仍不能修复它。）Rails的嵌套属性与

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）。

模式

/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（很肯定这是错的）

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

我没有任何直接的经验覆盖'Devise :: RegistrationsController'，所以我不知道如何解决你的问题。但我会建议创建自己的'users_controller.rb'，它具有'：new'和'：create'的动作。我们在应用程序中这样做，所以我们对整个请求 - 响应生命周期中发生的事情有全面的了解和控制。 –

谢谢@ Jay-ArPolidario ...在我自己的'users_controller.rb'中将'resource.bookings.new'添加到'：create'，然后在下面的输出中创建下面的错误（'“user_id不能为空”）： 'bookings_attributes：！ruby/hash：ActionController ::参数 '0'：！ruby/hash：ActionController ::参数 book_date：'2016-02-04T06：45：00 + 00：00' unit_type：One Bedroom agent_id：'1' 我怀疑它与在属性之前添加的'0'有关吗？思考？再次感谢 – Hughberto

@Hughberto我的回答对你有帮助吗？请让我们知道，并考虑将我的答案标记为已接受，我将不胜感激。谢谢 – SsouLlesS

有趣的是，它似乎错误是在我的预订模型中，我验证了lead_id，presence：true。删除它可以解决问题。感谢大家的帮助！

您的形式发送参数的方法是只附加1预订的用户，而不是“多”，这是你的客人到达您设计出一种方法：

"booking"=>{"book_date"=>"2016-02-11T09:15:00+00:00", "unit_type"=>"Two Bedroom", "agent_id"=>"1"}

这是因为在你的表格你使用的是单数符号：

#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 %>

如果你只是要附加1个预订喜欢它，使用以下命令：

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

然后如果你想允许一个以上的预订，然后只需添加复数在<%= f.fields_for :bookings do |booking_form| %>

，然后你可以在permit语句中使用booking_attributes: []。
