Module Innate::Helper::Flash
In: lib/innate/helper/flash.rb

Simple access to session.flash.

Flash is a mechanism using sessions to provide a rotating holder of key/value pairs.

Every request that is made will rotate one step, dropping contents stored two requests ago.

The purpose of this class is to provide an easy way of setting/retrieving from the current flash.

Flash is a way to keep a temporary pairs of keys and values for the duration of two requests, the current and following.

Very vague Example:

On the first request, for example on registering:

  flash[:error] = "You should reconsider your username, it's taken already"
  redirect R(self, :register)

This is the request from the redirect:

  do_stuff if flash[:error]

On the request after this, flash[:error] is gone.
