Hello,
I want to restrict my users having more than one address.
Here are the definitions from my classes :
class User < ActiveRecord::Base
has_one :address, dependent: :destroy
end
class Address < ActiveRecord::Base
belongs_to :user
validates :user, presence: true
validate :user_association
def user_association
unless Address.where(user_id: user.id).count == 0
errors.add(:user_id, 'Only one address per user')
end
end
end
I'm creating my address from user model, like this :
def create_address_relation
a = Address.create(address_type: @type.to_s, user_id: id)
self.address = a
end
However when I'm able to create two address objects for same user. (I'm using paranoia gem for soft deleting objects, not sure if that is relevant)
Any suggestion how to make validations work? except unique index on the db
