[英]How to save a belongs_to association for a polymorphic model with nested attributes?
For example I have these models: 例如,我有以下模型:
class Person < ActiveRecord::Base
# attributes: id, name
has_one :address, as: :addressable
accepts_nested_attributes_for :address
end
class Company < ActiveRecord::Base
# attributes: id, name, main_address_id
has_one :address, as: :addressable
belongs_to :main_address, class_name: 'Address', foreign_key: :main_address_id
accepts_nested_attributes_for :main_address
def main_address_attributes=(attributes)
puts '='*100
puts attributes.inspect
self.build_main_address(attributes)
self.main_address.addressable_id = self.id
self.main_address.addressable_type = self.class.to_s
puts self.inspect
puts self.main_address.inspect
end
end
class Address < ActiveRecord::Base
# attributes: id, address1, address2, city_id,..
belongs_to :addressable, polymorphic: true
validates :addressable_id, :addressable_type, presence: true
end
I am trying to save the Company
with nested attributes, you can assume this as the params: 我正在尝试使用嵌套属性保存
Company
,您可以将其视为参数:
{"name"=>"Test Company", "email"=>"", "display_name"=>"Company pvt ltd", "description"=>"Company desc", "founded_in"=>"2014-08-05", "website"=>"", "main_address_attributes"=>{"address1"=>"My address1", "address2"=>"My address2", "city_id"=>"10"}}
This doesn't work as it rejects and doesn't save data when addressable( addressable_id
and addressable_type
) for main_address isn't present, even when I am trying to add it in main_address_attributes=(attributes)
method in Company
class. 这不起作用,因为当main_address的 addressable(
addressable_id
和addressable_type
)不存在时,即使我试图在Company
类的main_address_attributes=(attributes)
方法中添加它,它也拒绝并且不保存数据。
Whenever I try to save this with the above params I get this error: 每当我尝试使用上述参数保存时,都会出现此错误:
Main address addressable can't be blank
How do I resolve this? 我该如何解决?
In case with belongs_to
you will have something like: company
related to address
(through main_address_id
) which in return is related to another( Company
or Person
) through polymorphic addressable
. 如果使用
belongs_to
您将拥有类似以下内容的信息:与address
相关的company
(通过main_address_id
),而该address
通过多态addressable
与另一个( Company
或Person
)相关。
As example you could change: 例如,您可以更改:
has_one :address, as: :addressable
to: 至:
has_many :address, as: :addressable
and then add to your Address
: 然后添加到您的
Address
:
enum address_type: [:primary, :secondary]
