i'm still new to rails and working on digesting everything i come across. recently i came across these two. what is the difference between attr_accessor and attr_accessible?
They are completely unrelated. attr_accessible and its counterpart attr_protected are there to help avoid users injecting parameters via mass assignment (ie Model.new would ignore them).
attr_accessor is a ruby method that is the combination of attr_reader & attr_accessor: it creates a pair of accessor methods for an instance variable (Don't use this for database attributes - Rails creates those accessors for you)

typo: attr_reader and attr_writer
