前言：我正在尝试为其创建一个具有嵌套地址表单的客户。单击创建客户后，我收到此错误。
ActiveModel::MassAssignmentSecurity::Error in Admin::CustomersController#create
Can't mass-assign protected attributes: address
客户模型
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
说我已经尝试了一切都是谎言，因为它不起作用，尽管我试图让它工作一段时间。
