How to show custom message when somebody clicks on refresh button of Coldfusion cfGrid (When session is out)? -

i using coldfusion (9.0.1) cfgrid populate data. code given below

<cfform id="viewnewcustomerreport" name="viewnewcustomerreport"> <div class="buttonclass"> <cfinput type="button" id="generatereport" name="generatereport" value="generate report" /> <cfinput type="hidden" name="filters" id="filters" bind="javascript:generatereport({generatereport@click})"/> </div> <br/> <div id="gridcontainer"> <cfgrid name="newcustomerreport" autowidth="yes" colheaderbold="true" selectonload="false" width="710" bind="url:index.cfm?fuseaction=reportscommon.getnewcustomerreport&page={cfgridpage}&pagesize={cfgridpagesize}&gridsortcolumn={cfgridsortcolumn}&gridsortdirection={cfgridsortdirection}&filter={filters}" bindonload="false" striperows="true" striperowcolor="##f6f6f6" format="html" pagesize="10"> <cfgridcolumn name="company_name" width="280" header="company name" /> <cfgridcolumn name="subject_assigned" width="280" header="subject assigned" /> <cfgridcolumn name="no_of_users" header="no. of users" width="180" /> </cfgrid> </div> <div id="wrapperdiv"><label id="lblerror" class="customerror"></label></div> </cfform>

and javascript part

var generatereport = function(filters){ var returnval; var checkform = $('#viewnewcustomerreport').validationengine('validate'); returnval = datefrom + '|' + dateto; if(checkform) { var gridobject = coldfusion.grid.getgridobject("newcustomerreport"); var store = gridobject.getstore(); store.addlistener("load",function(){ if(store.data.items == 0) { gridobject.setvisible(false); $("#gridcontainer").hide(); $("#wrapperdiv").show(); $("#wrapperdiv").css("text-align","center"); $("#lblerror").text("no record found").css({"font-size":"20px","font-weight":"normal"}); } else { gridobject.setvisible(true); $("#gridcontainer").show(); $("#wrapperdiv").hide(); } }); } else { $('#gridcontainer').hide(); } homecoming returnval; };

now if logout application in tab , refreshes grid show message

cfgrid: totalrowcount missing response info [enable debugging adding 'cfdebug' url parameters see more information]

when session out in homecoming json info collected {"issessionout":true} http status code 200 http status message ok

so question instead of showing default error message want show custom message session out please log in continue.

how can these achieved ?? in advance ......

every bind operation/ajax phone call in coldfusion has onerror/binderror handler function, can called @ time of error, or can phone call help of http response setting http status code.

whenever want self generated error message, can write code @ response/action page of site:

error = getpagecontext().getresponse().setstatus(306, "your session out");

(you can set http status code thing more 300 have checked 306 , works)

by can phone call onerror function of cfgrid

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...
