Convenience accessor for flash
Convenience accessor for flash=
Marks the entire flash or a single flash entry to be discarded by the end of the current action:
flash.discard # discard the entire flash at the end of the current action flash.discard(:warning) # discard only the "warning" entry at the end of the current action
Keeps either the entire current flash or a specific flash entry available for the next action:
flash.keep # keeps the entire flash flash.keep(:notice) # keeps only the "notice" entry, the rest of the flash is discarded
Convenience accessor for flash
Convenience accessor for flash=
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'].
Used internally by the keep and discard methods
use() # marks the entire flash as used use('msg') # marks the "msg" entry as used use(nil, false) # marks the entire flash as unused (keeps it around for one more action) use('msg', false) # marks the "msg" entry as unused (keeps it around for one more action)
Returns the single value for the key you asked to be marked (un)used or the FlashHash itself if no key is passed.
