caching - How to detect stale data in search result with paging? -

let's have rest api search: /items?querystring=foo&pagesize=20&page=3

as search results fetched page after page, search total results might alter , items of each page might vary while browsing through pages.

what kind of approaches there observe changes in data? total number of result 1 indication not fool proof.

usually there none detection. when come in page, new request done (rest) , recent info page displayed. google says 'about x results in total'. if insist on having counter fixed, have stop calling service 'a rest', take snapshot first search , display disabled entries when user browse pages

caching search language-agnostic

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...
