Like db: seed of a model and all its nested models?

Question

I have the following classes:

class User
  has_one :user_profile
  accepts_nested_attributes_for :user_profile
  attr_accessible :email, :password, :password_confirmation, :user_profile_attributes
end

class UserProfile
  has_one :contact, :as => :contactable
  belongs_to :user
  accepts_nested_attributes_for :contact
  attr_accessible :first_name,:last_name, :contact_attributes
end

class Contact
   belongs_to :contactable, :polymorphic => true 
   attr_accessible :street, :city, :province, :postal_code, :country, :phone
end

I am trying to insert a record in all 3 tables as follows:

consumer = User.create!(
  [{
  :email => '[e-mail]',
  :password => 'aaaaaa',
  :password_confirmation => 'aaaaaa',
  :user_profile => {
      :first_name => 'Gina',
      :last_name => 'Davis',
      :contact => {
        :street => '221 Baker St',
        :city => 'London',
        :province => 'HK',
        :postal_code => '76252',
        :country => 'UK',
        :phone => '2346752245'
    }
  }
}])

The record is inserted in the table users, but not in the tables user_profilesor contacts. The error also does not occur.

What is the right way to do this?

solvable (thanks @Austin L. for the link)

params =  { :user =>
    {
    :email => '[e-mail]',
    :password => 'aaaaaa',
    :password_confirmation => 'aaaaaa',
    :user_profile_attributes => {
        :first_name => 'Gina',
        :last_name => 'Davis',
        :contact_attributes => {
            :street => '221 Baker St',
            :city => 'London',
            :province => 'HK',
            :postal_code => '76252',
            :country => 'UK',
            :phone => '2346752245'
          }
      }
  }
}
User.create!(params[:user])

Answer 1

Your user model must be configured to accept nested attributes using accepts_nested_attributes

See the Rails documentation for more information and examples: http://api.rubyonrails.org/classes/ActiveRecord/NestedAttributes/ClassMethods.html

: has_one :contact, :through => :user_profile, : @contact = User.first.contact.

2: rails c , , :

@c = Contact.new(#all of the information)
@up = UserProfile.new(#all of the information, :contact => @c)
User.create(#all of the info, :user_profile => @up)
