Hello,

I felt annoyed enough when having to redirect user back to their  
previous location in a hackish way that I wrote this plugin.

It avoids storing POST and Ajax request. It also has a facility to  
specify actions not to store in the history.

If you are interested, it’s there:

See you all,

Damien

If you ask Chuck Norris what time it is, he always says, “Two seconds  
'til.”  
After you ask, “Two seconds 'til what?” he roundhouse kicks you in the  
face.

Looked to me like a good plugin to explain those metaprogramming  
idioms. I blogged about it here:

Thank you very much! I did not thought it could serve as tutorial.  
Great article.

Quick point, as Xavier’s diary doesn’t support comments.

Module#append\_features is deprecated. Module#included is the new kid  
on the block, and no need to call super!

def self.included(base)  
base.extend(ClassMethods)  
end

Thank you!

Is there a reason to call class\_eval inside history()?

def history(options)  
logger.debug(“history: setting up history”)  
include History::InstanceMethods  
class\_eval do  
ActionController::Base.history\_container =  
History::Container.new(options)  
after\_filter :store\_location  
end  
end

Wouldn’t that code work without class\_eval? (See mock-up below, where  
croak is after\_filter, and tryme is history)

– fxn

class Base  
def self.croak  
puts “croak! in #{self}”  
end  
end

module M1  
def self.included(base)  
base.extend(M2)  
end

module M2  
def tryme  
croak  
end  
end  
end

class Base  
include M1  
end

Base.tryme # -\> croak! in Base
