Ruby on Rails - Nested attributes not working

Question

I have this two simple models:

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

And

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

I'm trying to create some stub Communities using a seed.rb:

def self.create_community(administrators: [], residents: [], address: {})
     Community.create(
        name:  Faker::Name.name,
        administrators: administrators,
        residents: residents,
        address_attributes: address
      )

    @communities += 1
  end

But I always get:

ActiveRecord::RecordInvalid: Validation failed: Address community must exist

PS: Also tried using "community.create_address" and other things. To only way I could get it to work was:

Saving Community (with no address)
Saving Address referencing community_id.

But I had to hack my Model and remove :address from the validates method in community.rb.

So how can I make accepts_nested_attributes_for work?

I think you are using Rails 5. This issue is because of feature change in Rails 5. For more info read this. You should try adding optional: true to belongs_to relationship. Like this.

class Address < ApplicationRecord
    belongs_to :community, optional: true
end
