  [@company,@user].each {|ins|
      raise ActiveRecord::RecordInvalid.new(ins) unless ins.valid?
    }
  User.transaction do

I am not getting error messages through <%= f.error_messages %> please help!!

A solution:

In your Company model:

 accepts_nested_attributes_for :user

In your controller:

def create
  @company = Company.new(params[:company].merge(:user_attributes => params[:user])
  if @company.save
    #what you want
  else
    @user = @company.user          
    render :action => 'new'
  end
end
