Rails - Mar 2012 - Cannot set an attribute in my Join table .... do you think it matters which controller I use?

I tried out some code in my console and I am having difficulty
translating it for my view and controller so that it gives me the same
result.
My console:

        @contract = Contract.new(authnum: "900700",
st_date:"2012-01-01", end_date: "2012-30-06")

        @contract.save

        @code = Code.new(code_name: "S-5463", status:
"Active",  description: "This and That")

        @code.save

        @codeline = @code.codelines.build(:units_alloc => "80.00",
:contract => @contract)

        @codeline.save

        @codeline
        => #<Codeline id: 91, contract_id: 64, code_id: 54, units_alloc:
80.00>

Using pgadmin3 I check my codelines table and I get the same result namely:

        id    contract_id    code_id   units_alloc
        91         64            54       80.00

But if I try to run this through my contracts_controller and view I get:

        id    contract_id    code_id   units_alloc
        1         1           1               ---I think this record comes from
the *@contract.codes.build*
        1         1                     80.00 ---I think this record comes from
the *@contract.codelines.build(:units_alloc => params[:units_alloc],:contract
=> @contract)*


Here are my models:

  class Contract < AR::Base
    has_many :codelines
    has_many :codes, :through => :codelines

    accepts_nested_attributes_for :codes

    attr_accessible :codes_attributes,:codes,:authnum,:st_date,:end_date
  end

  class Codeline < AR::Base
    belongs_to :contract
    belongs_to :code
    units_alloc ...... *this is the attribute I would like to set*
  end

  class Code < AR::Base
    has_many :codelines
    has_many :contracts, :through => :codelines
  end

The new/create action of my app/controllers/contracts_controller.rb

  def new
    @contract = Contract.new
    @contract.codes.build
    @contract.codelines.build(:units_alloc => params[:units_alloc],:contract
=> @contract)
  end

  def create
     @contract = Contract.new(params[:contract])
     if @contract.save
       flash[:success] = "New Contract has been saved"
       redirect_to @contract
     else
       @title = "You have some errors"
       render ''new''
     end
   end

the partial for my view in app/views/contracts/_fields.html.haml

    = f.fields_for :codes do |ff|
      .field
         = ff.label :name, "Code Name"
         %br/
         = ff.text_field :code_name
      .field
      .
      .
    = f.fields_for :codelines do |ff|
      .field
        = ff.label :name, "Units Alloc"
        %br/
        = ff.text_field :units_alloc

Can you please have a look at this and give me some direction?

Thanks.

Something you think should be happening isn''t happening. I
don''t see
any debugging code in your files.

Are you using your log file to verify the parameters being passed in
from your form and review the queries being executed?

You might want to avoid mass assignment for security reasons and to
give more control.
For example, in your controller,

     :stuff = { :authnum    => params[:contract][:authnum],
                  :st_date      => params[:contract][:st_date],
                  :end_date    => params[:contract][:end_date] }
     logger.debug("------------------------ stuff #{stuff.inspect}")
     @contract = Contract.new(stuff)
