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:

http://juixe.com/techknow/index.php/2007/01/22/ruby-class-tutorial/

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.

on the comments example i gave you go to the article.rb there is an explanation

also look at this

http://railscasts.com/episodes/26-hackers-love-mass-assignment

you can mail me directly for simple questions like this at

rbritom@gmail.com

that way you wont use up all your “calling credit”

Thanks all for your replies.

And, really appreciate it @radhames.

It's a sign that you need to go learn Ruby. :slight_smile:

Thanks.

Sure @Marnen :slight_smile:
