Question

前言：我正在尝试创建一个具有嵌套地址表单的客户。点击创建客户后，我收到此错误。

ActiveModel::MassAssignmentSecurity::Error in Admin::CustomersController#create

Can't mass-assign protected attributes: address

客户模式

class Customer < ActiveRecord::Base
 attr_accessible :name, :email, :phone, :addresses_attributes
 has_many :addresses
 accepts_nested_attributes_for :addresses, :allow_destroy => true
end

地址模型

  class Address < ActiveRecord::Base
    attr_accessible :street, :city, :state, :zip, :customer_id
    belongs_to :customer
    has_one :customer_id
end

客户控制器

ActiveAdmin.register Customer, :sort_order => "name_asc" do
    # Menu item
  menu :label => "Customers", :parent => "Administration"

  filter :name
  filter :created_at
  filter :updated_at

  action_item :only => [:show] do
    link_to "Contacts", client_contacts_path( resource )
  end

  index do |t|
    selectable_column
    column(:name, sortable: :name) { |customer| link_to truncate(customer.name, length: 35), customer, title: customer.name }
    column "Created", :sortable => :created_at do |customer|
      customer.created_at.humanize
    end
    column "Updated", :sortable => :updated_at do |customer|
      customer.updated_at.humanize
    end
    column "" do |customer|
      restricted_default_actions_for_resource(customer) + link_to( "Contacts", client_contacts_path(customer), :class => "member_link" )
    end
  end

    form :partial => "form"

  show :title => :name do
      panel "Customer Details" do
          attributes_table_for resource do
            row :name
            row :email
            row :phone
            row :created_at do
              resource.created_at.humanize
            end
            row :updated_at do
              resource.updated_at.humanize
            end
          end
        text_node(render :partial => "admin/addresses/show", :locals => { :address => resource.address })
      end
    end
end

说我已经尝试过所有事情都是谎言，因为它不会起作用，尽管我试图让它工作一段时间。

Answer 1

您必须add

 accepts_nested_attributes_for :addresses

在您的客户模型中。

那么，为什么错误是单数的（地址而不是地址）？

您也必须将:addresses_attributes添加到attr_accessible调用。

还有一个无法大量分配受保护的属性：地址帖子
