ruby on rails - Session Timeout Message in RoR using Devise -

i have application secured devise , session timeout of 30 minutes. devise working normal navigation, if user clicks on link when timed out redirected login screen message saying "your session expired, please sign in 1 time again continue.", excellent.

however have ajax in lot of places. if session times out , user ajax operation want same behavior above rather silently failing 401 error in background.

so far have jquery code on each page grab 401s , reload:

$(document).ajaxerror(function(e, error) { switch(error.status) { case 401: { // unauthorised (possible timeout) location.reload(); break; }

it works enough, there annoying issue:

because ajax request hits devise first, when application reloads page directed login page, don't see timeout message, see unauthenticated "you need sign in or sign before continuing." message.

is there way ensure on sec request devise still shows timeout message?

i think need manually show message, illustration redirecting specific url or setting query parameter.

the problem is, after 401 request got new session , when reload browser, next request nail application empty session. that's why unauthenticated message.

ruby-on-rails ajax ruby-on-rails-3 authentication devise

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
