[英]Ruby on Rails - Nested attributes not working
我有兩個簡單的模型:
class Address < ApplicationRecord
belongs_to :community
geocoded_by :full_address
validates :address, :city, :province, :country, presence: :true
validates :postalcode, presence: true, postalcode: true
after_validation :geocode
def full_address
[address, province, postalcode, country].compact.join(', ')
end
end
和
class Community < ApplicationRecord
has_one :address, dependent: :destroy
accepts_nested_attributes_for :address
has_many :community_people, dependent: :destroy
has_many :people, through: :community_people, source: :user
validates :name, :address, :administrators, presence: true
# ...
end
我正在嘗試使用seed.rb創建一些存根社區:
def self.create_community(administrators: [], residents: [], address: {})
Community.create(
name: Faker::Name.name,
administrators: administrators,
residents: residents,
address_attributes: address
)
@communities += 1
end
但是我總是得到:
ActiveRecord::RecordInvalid: Validation failed: Address community must exist
PS:還嘗試使用“ community.create_address”和其他方法。 我唯一可以使它工作的方法是:
但是我不得不修改我的模型,並從community.rb的validates
方法中刪除:address
。
那么如何使accepts_nested_attributes_for工作呢?
我認為您正在使用Rails5。此問題是由於Rails 5中的功能更改引起的。有關更多信息, 請閱讀this 。 您應該嘗試添加optional: true
belongs_to
關系。 像這樣。
class Address < ApplicationRecord
belongs_to :community, optional: true
