now

Sets a flash that will not be available to the next action, only to the current.

flash.now[:message] = "Hello current action"

This method enables you to use the flash as a central messaging system in your app. When you need to pass an object to the next action, you use the standard flash assign (`[]=`). When you need to pass an object to the current action, you use `now`, and your object will vanish when the current action is done.

Entries set via `now` are accessed the same way as standard entries: `flash[‘my-key’]`.

Also, brings two convenience accessors:

flash.now.alert = "Beware now!"
# Equivalent to flash.now[:alert] = "Beware now!"

flash.now.notice = "Good luck now!"
# Equivalent to flash.now[:notice] = "Good luck now!"
