How do I replicate my console exercise in my view and controller?

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 = "900700", st_date: "2012-01-01",         end_date: "2012-30-06")

        @code = "S-5463", status: "Active",         description: "This and That")

        @codeline = => "80.00",         :contract => @contract)

        @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         91 64 54         92 64 80.00

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 = => params[:units_alloc],     :contract => @contract)   end

  def create      @contract =[:contract])      if        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

Please have a look to see if you can help me translate my console code into the appropriate code for my contracts_controller?
