Rails - Jul 2006 - Creating multiple objects from form data

I''m in the process of creating a sign up form for an online
application.
The form collects account info, company info, and then info for an
administrative user.

The method looks like this:

def create
  @account = Account.create!(params[:account])
  @company = @account.companies.create!(params[:company])
  @user = @company.users.create!(params[:user])
end


However, this inevitably fails on validation and ActionController comes back
saying that "Validation failed: Username can''t be blank, First
name can''t be
blank, Last name can''t be blank, Email address can''t be
blank"

However, values for user are present in the request parameters:

*Parameters*: {"company"=>{"name"=>"poop",
"account_id"=>29},
"user"=>{"password_confirmation"=>"poop",
"username"=>"poop",
"company_id"=>29, "time_zone"=>"International
Date Line West",
"first_name"=>"poop",
"password"=>"poop",
"last_name"=>"poop",
"email_address"=>"poop"},
"account"=>{"name"=>"poop",
"url"=>"poop"}}

I''ve tried using User.new(params[:user]) with the same results.  The
only
thing that has given me something different is to loop through the
key/values from params[:user].  I''m a bit stumped here, and any help is
appreciated.

Thanks,

Jeremiah

Curiously enough, when I run this same sequence of code through
script\console, I get the same error.

account = Account.create!(:name => "poop", :url =>
"poop")
company = account.companies.create!(:name => "poop")
user = company.users.create!(:first_name => "poop", :last_name
=> "poop",
:username => "poop", :email_address => "poop",
:password => "poop",
:password_confirmation => "poop")

produces

ActiveRecord::RecordInvalid: Validation failed: Username can''t be blank

Here''s the code from the user model

require ''digest/sha2''

class User < ActiveRecord::Base
  belongs_to :account
  belongs_to :company
  belongs_to :department
  belongs_to :address
  belongs_to :default_project,

             :foreign_key => ''default_project_id''
  has_and_belongs_to_many :roles
  has_and_belongs_to_many :projects
  has_and_belongs_to_many :meetings

  validates_uniqueness_of :username
  validates_confirmation_of :password
  validates_presence_of :username
  #validates_presence_of :password
  #validates_presence_of :password_confirmation
  #validates_presence_of :first_name
  #validates_presence_of :last_name
  #validates_presence_of :email_address

  cattr_accessor :current_user

  attr_accessor :password, :password_confirmation
  attr_accessible :password, :password_confirmation

  def hashed_password=(pass)
    salt = [Array.new(6){rand(256).chr}.join].pack("m").chomp
    self.password_salt, self.password_hash = salt,
Digest::SHA256.hexdigest(pass
+ salt)
  end

  def self.authenticate(username, password)
    user = User.find(:first, :conditions => [''username =
?'', username])
    if user.blank? || Digest::SHA256.hexdigest(password + user.password_salt)
!= user.password_hash
      raise "Username or password invalid"
    end
    user
  end
end

Guess I didn''t read my own code close enough.  I was blocking myself
with
attr_accessible.
