Rails - Mar 2006 - dumb question: what is attr_xxxx

i''m very new to the rails scene and am seeing lines of code like 
attr_reader, attr_writer, attr_accessor, etc... and have no idea what 
they do. reading the section in the book i''m reading that explains the 
previous block of code says nothing about it really.

I can recommend reading up on your Ruby syntax. The pick axe book is an 
good start. Its for sale in any bookshop but also on-line here: 
http://www.rubycentral.com/book/.

"attr_reader" is a method that will generate an instance variable, and
a
reader (a.k.a. getter) for it in your class. The others also create 
setters, etc.

Have fun,
     Erik.
