attr_accessor

I'm looking at an example here: http://stackoverflow.com/questions/1330273/how-to-calculate-difference-of-two-fields-on-form-submit-ruby-on-rails

And, came along this line in MyModel:

attr_accessor :start_amount, :end_amount

What is "attr_accessor"?

Thanks.

This isn't a Rails specific question, as attr_accessor is built-in Ruby functionality.

Perhaps you should take a look at a Ruby tutorial about classes:

Can I ask how long you spent trying to answer this for yourself? _Please_ do some basic Ruby tutorials and also get and read the Pickaxe Ruby book. If you keep asking such basic questions here people will eventually get tired of answering them, and when you really need help with a tricky problem you will have used up all your calling credit.
