is there way force scheduled job runs performed user, instead of user enabled scheduling? thanks edit: sorry, maybe didn't explain myself properly. meant rundeck user, not node user, defined in realm.properties file. let's have 2 users defined: user1 , user2. user1 logs rundeck , starts job. in recent executions list job appear performed "by user1". user1 edits job , enables "schedule run repeatedly" option. when job starts on schedule reported ran "by user1". what need way tell rundeck jobs have "schedule run repeatedly" enabled should run user (such user2) instead of user edited them , enabled scheduling (user1). why want this? 2 reasons: 1. cleanliness: want automated jobs listed ran "rundeck service" user. 2. issues ldap , acls: our rundeck users imported ldap , rundeck acls set ldap groups. when job run on schedule rundeck not call ldap server retrieve group list, user treated having no group , consequen...

i stuck in design scenario have javascript/html5 based application runs in offline mode . browser based , there crud operations happen. now when in offline mode maintain server time in application. server time needed crud operations etc how maintain server time using javascript/html5 when running locally? note : application contacts server first time , downloads data, can fetch time too. ** i cannot calculate server time using device's local time because user can change device's time , create fraud entries. ** you can't, there's no way of stopping users changing time on device , can't contact online server if have no network connection. if verifiable audit crucial should record time when updates hit server rather attempting record time updates hit device. of course, nothing stopping doing both.

i find changing data design via acce slow process , might cause human errors. propagating changes 1 environment seems quite tedious (for example dev test). is there way propagate data design changes other p8 environments? maybe it's possible write kind of update scripts? filenet ships program called "filenet deployment manager" fdm. this helps take tediousness away pushing changes dev through prod. if prod environment established, need rebuild dev environments first deploying production backwards. i suggest looking tool, learning strengths , weaknesses. has helped out bunch. btw fdm has vastly improved 4.5.1 5.2.1. can deploy global objects marking sets etc.

is possible target last n sibling elements when there y siblings? for example have list of items, if , only if there 8, 11, 14... etc sibling elements want last 2 different (so 8 + 3n ). if there other amount of children want them same. the easiest way far target each of 2 elements want style own set of pseudo-classes. the last child, state, represented 3n+8 (8, 11, 14...). follows penultimate child 3n+7 (7, 10, 13...). li:nth-last-child(1):nth-child(3n+8), li:nth-last-child(2):nth-child(3n+7) { color: red; } ul { counter-reset: item; list-style-type: none; } li { display: inline; padding: 0.25em; } li::before { content: counter(item); counter-increment: item; } <ul><li><li><li><li><li><li><li><li></ul> <ul><li><li><li><li><li><li><li><li><li></ul> <ul><li><li><li><li><li><li><l...

i attempting write function convert function. function should work follows: check see if function , if returns it. check see if string , if there global function name, if return that. check see if string can evaluated , if return lambda (anonymous) function evaluates string. if previous attempts convert value function fail, return lambda (anonymous) function returns value. how handle other variable types (numbers, null, undefined, boolean, objects , arrays). function caneval(str){ try { eval(str); } catch (e){ return false; } return true; } function tofunc(v){ if(typeof(v) == "function") return v; if(typeof(v) == "string"){ if( window[v] != undefined && typeof(window[v]) == "function" ) return window[v]; if(caneval(v)) return function(){eval(v)}; } return function(){return v;}; }; the problem code caneval evaluates code, in circumstances not want code (in string) run more once. evaluates str...

i sending email in odoo 8 python code several users. to using send_mail method email.template model, but, have pass 1 user id method, have loop send mail users: for user in users: if user.partner_id , user.partner_id.email: mails_sent &= self.pool.get('email.template').send_mail( self.env.cr, 1, template.id, user.id, force_send=true, context=context) my question is: how can send 1 email users instead of 1 email each user? you need see hr odoo 8 inherit class mail.thread _inherit = ['mail.thread'] #..... #after can call id_msg = self.message_post( cr, uid, false, body=message, partner_ids=[id1,id2,id3], subtype='mail.mt_comment', context=context ) i hope :)

i testing itertools.groupby() , try groups lists can't figure out how make work. using examples here, in how use python's itertools.groupby()? from itertools import groupby things = [("animal", "bear"), ("animal", "duck"), ("plant", "cactus"), ("vehicle", "speed boat"), ("vehicle", "school bus")] i tried (python 3.5): g = groupby(things, lambda x: x[0]) ll = list(g) list(tuple(ll[0])[1]) i thought should first group ("animal") list ['bear', 'duck'] . empty list on repl. what doing wrong? how should extract 3 groups lists? if want groups, without keys, need realize group generators go, per docs : because source shared, when groupby() object advanced, previous group no longer visible. so, if data needed later, should stored list. this means when try list -ify groupby generator first using ll = list(g) , before...

i used excel 2016 create excel table vba program generate word document report automatically. macro generates compile error when used on excel 2013 older office library. i tried following without success: using older version of excel save macro (no improvement). changing code (e.g: word.application -> object) proposed on other threads. main problem program ~2000 lines long , when fix something, compile error arise few lines later. plus, formatting in word document altered. updating office 2016 not solution either various compatibility reasons other programs. the remaining solution can see export microsoft office 16.0 office library , microsoft excel 16.0 library computers running excel 2013 , adding them vba references. i cannot locate these 2 libraries. path shown in tools->references window cut because window short (and of course not possible resize). what path , file name 2 libraries? do think solution work , if not, know better 1 or workaround?
