# action that sets <tt>flash[:notice] = "Successfully created"</tt> before redirecting to a display action that can
# then expose the flash to its template. Actually, that exposure is automatically done. Example:
#
- # class WeblogController < ActionController::Base
+ # class PostsController < ActionController::Base
# def create
# # save post
# flash[:notice] = "Successfully created post"
- # redirect_to :action => "display", :params => { :id => post.id }
+ # redirect_to posts_path(@post)
# end
#
- # def display
+ # def show
# # doesn't need to assign the flash notice to the template, that's done automatically
# end
# end
#
- # display.erb
- # <% if flash[:notice] %><div class="notice"><%= flash[:notice] %></div><% end %>
+ # show.html.erb
+ # <% if flash[:notice] %>
+ # <div class="notice"><%= flash[:notice] %></div>
+ # <% end %>
#
# This example just places a string in the flash, but you can put any object in there. And of course, you can put as
# many as you like at a time too. Just remember: They'll be gone by the time the next action has been performed.
