Ruby on rails 当我在activeadmin中单击“创建”时，我得到一个质量分配错误

所以我有主动管理员。我有一个客户模型和一个地址模型。我的地址嵌套在客户中。当我单击“创建客户”时，我得到一个质量分配错误

错误

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

   attr_accessible :name, :email, :phone, :addresses_attributes
  has_many :addresses
  accepts_nested_attributes_for :addresses, :allow_destroy => true

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

在地址模型中，您不需要在attr\u accessible方法中引用客户id，也不需要声明客户id

您已经使用“属于”和“拥有”设置了两个模型之间的关系

确保您有：

t、 参考资料：联系方式

---

在您的地址迁移中。

您确实为has\u-one关系构建表单，但您有多个has\u-one关系

 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 像

如果您有一个关系，则将模型声明更改为

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

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

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

class客户true
结束

地址模型

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

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

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