Question

I’m using Devise for authentication with two custom fields added = :organization_id and :username. I also generated a scaffold for the Organization which simply consists of Name.

Currently when users sign up they can type in an Organization ID (integer) and a username (string).

Users belong_to organizations, and organizations has_many users.

Here’s what my models look like (I left everything else untouched except for the files inside app/views/devise/registrations to add organization_id and username):

#user.rb

class User < ActiveRecord::Base
  belongs_to :organization
  # Include default devise modules. Others available are:
  # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me, :organization_id, :username

end

#organization.rb

class Organization < ActiveRecord::Base
  has_many :users
end

What I would like is for an organization to be automatically created when a user signs up without the user having to specify the organization_id.

Also, ideally the @organization.name would be exactly the same as :username

How would I go about doing this?

I’ve seen the Railscast on nested model forms but he’s creating a question inside the survey form, and questions belong to a survey. I need to do it the other way around (create an organization inside the user form, where users belong to a survey.)

Any help and suggestions would be greatly appreciated..

Answer 1

class User < ActiveRecord::Base
  before_create :create_organization

  private
  def create_organization
    self.organization = Organization.create :name => self.username
  end
end

The create_organization method will be executed right before the sql query which creates the user. It’ll create a new organization and assign it to the user.
