Flash:EFI"ActionDispatch::Flash;FI" Object;To:RDoc::Markup::Document: @parts[o;;[o: RDoc::Markup::Paragraph;[ I"yThe flash provides a way to pass temporary objects between actions. Anything you place in the flash will be exposed ;TI"uto the very next action and then cleared out. This is a great way of doing notices and alerts, such as a create ;TI"|action that sets flash[:notice] = "Post successfully created" before redirecting to a display action that can ;TI"cthen expose the flash to its template. Actually, that exposure is automatically done. Example:;To: RDoc::Markup::BlankLine o:RDoc::Markup::Verbatim;[I"4class PostsController < ActionController::Base
;TI" def create
;TI" # save post
;TI"6 flash[:notice] = "Post successfully created"
;TI"' redirect_to posts_path(@post)
;TI" end
;TI"
;TI" def show
;TI"^ # doesn't need to assign the flash notice to the template, that's done automatically
;TI" end
;TI" end
;TI"
;TI"show.html.erb
;TI" <% if flash[:notice] %>
;TI"9 <%= flash[:notice] %>
;TI" <% end %>
;T: @format0o; ;[I"aSince the +notice+ and +alert+ keys are a common idiom, convenience accessors are available:;T@o; ;[I"+flash.alert = "You must be logged in"
;TI"0flash.notice = "Post successfully created"
;T; 0o; ;[I"xThis example just places a string in the flash, but you can put any object in there. And of course, you can put as ;TI"smany as you like at a time too. Just remember: They'll be gone by the time the next action has been performed.;T@o; ;[I"FSee docs on the FlashHash class for more details about the flash.;T:
