[ruby-dev:30718] Problem: insert data in two tables from an input form.

Hi guys,
I have two tables.
Table1: output_columns  (3 columns)
Table2: file_datas      (2 columns)
In any table I can search, show, edit data. But how can I insert data in
two table?
In my input form there are 5 input fields. I want to input 3 data in
table1 and last 2 data in table2. In the OutputColumnsController (the
controller of table1) I have written the following code
def create
    @output_column = OutputColumn.new(params[:output_column])
    if @output_column.save
      flash[:notice] = 'OutputColumn was successfully created.'
      redirect_to :action => 'list'
    else
      render :action => 'new'
    end
  end
    By this code I can save in the table1. But how can I handle the
input data in table2?
Plz help me.
