hi all,
using rails 1.2.3 on windows xp
i have a controller method like so:
def index
...do stuff...
if some_error
flash[:notice] = "error!"
end
end
and the layout has:
<% if flash[:notice] -%>
<div class="flash"><%= flash[:notice] %></div>
<% end -%>
the form for index submits via GET method. if i cause the some_error
condition through the form, i get the flash message as expected.
however, if i immediately submit again with conditions that do not
cause some_error, i still get the flash message again. it takes until
submitting a third time for the flash message to clear. isn''t it
supposed to clear itself after it renders the first time in the
layout? i know i''m not setting it again because i have a debug
statement when it gets set in the controller.

What you describes maps with my understanding of flash. From ActiveController:Flash: "Anything you place in the flash will be exposed to the very next action and then cleared out." I think what you want is flash.now: flash.now[:notice] = "error!" - Hal jemminger wrote:> hi all, > > using rails 1.2.3 on windows xp > > i have a controller method like so: > > def index > ...do stuff... > if some_error > flash[:notice] = "error!" > end > end > > and the layout has: > <% if flash[:notice] -%> > <div class="flash"><%= flash[:notice] %></div> > <% end -%> > > the form for index submits via GET method. if i cause the some_error > condition through the form, i get the flash message as expected. > however, if i immediately submit again with conditions that do not > cause some_error, i still get the flash message again. it takes until > submitting a third time for the flash message to clear. isn''t it > supposed to clear itself after it renders the first time in the > layout? i know i''m not setting it again because i have a debug > statement when it gets set in the controller.--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
