Question

所以我有活跃的管理员。我有一个客户模型和一个地址模型。我在客户中嵌套了地址。当我点击创建客户时，我收到批量分配错误。

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 do
    # Menu item
  menu :label => "Customers", :parent => "Administration"

  filter :name
  filter :created_at
  filter :updated_at


  index do
    column :name
  end

    form :partial => "form"

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

Answer 1

在地址模型中，您不需要在attr_accessible方法中引用customer_id，也不需要声明costumer_id。

您已经使用belongs_to和has_may设置了两个模型之间的关系。

确保您拥有：

Answer 2

你为has_one关系构建表单，但你有has_many一个。

 f.inputs "Addresses" do
        f.has_many :addresses do |t|
             t.input :street 
             t.input :city 
             t.input :state
             t.input :zip, as: :string

      end
end

在这种情况下，您的模型应该看起来像

如果您有has_one关系，则将模型声明更改为

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
end

如果您有has_one关系，则将模型声明更改为

客户模式

class Customer < ActiveRecord::Base
   attr_accessible :name, :email, :phone, :address_attributes
  has_one :address
  accepts_nested_attributes_for :address, :allow_destroy => true
end

地址模型

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

当我在activeadmin中单击create时，我收到了一个质量分配错误
