For some reason, which I cannot detect, no flash notices that I set
prior to redirects are available after the redirect.
This standard "forgot password" action as an example:
def forgot
if request.post?
user = User.find_by_email(params[:user][:email])
if user
user.create_reset_code
flash[:notice] = "A reset email was sent to #{user.email}"
redirect_back_or_default(''/'')
else
flash[:notice] = "The email #{params[:user][:email]} does not
exist in system"
redirect_to forgot_path
end
end
end
If I enter a bad email address, the forgot action/view should redisplay
with the flash message. Up until a little while ago, it did. Something
changed, but I am not sure what it is. Flash messages that are set
before renders do display (my layouts contain the display of the flash
message, so are available on most every page).
Using the debugger, I have verified that just after the flash[:notice]
statement, the flash hash is set correctly. But when processing returns
to the forgot method after the redirect, the flash hash is empty. So it
seems that the message is not making to the session, or is not being
restored from the session.
Sessions are working properly otherwise.
Any thoughts would be greatly appreciated.

As far as I know, the flash is only available to the next request after the current request, and then it''s automatically deleted. So if your flash is empty, there must have been two requests since you set the flash. A redirect causes the browser to issue a new request. Is there a second redirect in your code somewhere? -- Posted via http://www.ruby-forum.com/.

I was thinking along the same lines, so checked the console after issuing a request that should end with a displayed flash message and saw that there was only a single redirect. I also tried adding "keep" to the flash set statement, but alas, no message appeared. I am really stumped on this one. -- Posted via http://www.ruby-forum.com/.

Take that out and everything worked properly. However this might be something worth looking at too: https://rails.lighthouseapp.com/projects/8994/tickets/2200-session-support-broken Ta Luke -- Posted via http://www.ruby-forum.com/.

I use embedded Active Scaffolds, so need to have render component installed. I commented out a line that called flash.sweep: def assign_shortcuts_with_render_component(request, response) assign_shortcuts_without_render_component(request, response) flash(:refresh) #flash.sweep if @_session && !component_request? end which seems to make things work without breaking others, but I can''t be too sure. I sent a message to the author of render_component and have not heard whether this is a bad thing to do. Tom -- Posted via http://www.ruby-forum.com/.
