Rails - Mar 2011 - difference between attr_accessor and attr_accessible?

Hi,

What''s the difference between attr_accessor and attr_accessible?

Is attr_accessor to create a virtual variable/object and attr_accessible
makes it accessible?  Do you need attr_accessible if you already have
attr_accessor?

Thanks!

They''re completely unrelated. attr_accessor is a pure ruby method and
creates a setter & getter method for an instance variable.

attr_accessible (and its counterpart attr_protected) are railsisms and
are there to control which properties of an object a user can change
through mass assignment

This is mass assignment:

User.new(params[:user])

Basically assigning all the attributes to the an instance based on the 
params[:user] hash.
