Readline

GNU readline is a commonly used library for line-editing; it is used for example by Bash, FTP, and many more (see the details of [readline][5] package under "Required By" for more examples). readline is also customizable (see man page for details).

belongs_to:

1. Assigning an object to a belongs_to association does not automatically save the object. It does not save the associated object either.

has_one:

1. When you assign an object to a has_one association, that object is automatically saved (in order to update its foreign key).
2. In addition, any object being replaced is also automatically saved, because its foreign key will change too
3. If either of these saves fails due to validation errors, then the assignment statement returns false and the assignment itself is cancelled.
4. If the parent object (the one declaring the has_one association) is unsaved (that is, new_record? returns true) then the child objects are not saved. They will automatically when the parent object is saved.

To be able to use PHP5 PDO with MS Access mdb files the following is required (the same applies for the PHP4 style of using odbc_X except for the obviously PDO specific requirements):

PHP ODBC module

In Linux this is achieved by intalling the php5-odbc package:

module A
  def do_something
    puts 'A->do_something'
    super
  end
end

module B
  def do_something
    puts 'B->do_something'
