i need check if django query has values if not need append dict query set validation purpose. so, don't want create entry in database. obviously, since can't append queryset(attribute error) there other way add this? listing = listing.objects.values() if len(listing) < 1: listing.append({ 'address': 'some string', 'range': 'some other string' }) if want manually create list when queryset empty, that's rather easy listing = listing.objects.values() if len(listing) < 1: listing = [{ 'address': 'some string', 'range': 'some other string' }] if want append regardless of whether queryset empty or not: listing = list(listing.objects.values()) listing.append({ 'address': 'some string', 'range': 'some other string' })

how concat html , tell php send html in end of recursive loop ? i have recursive loop build tree table (parent-child) nodes. functions work want return full html not print it, use return, breaks foreach loop. function show_full_tree($ne_id) { $store_all_id = array(); $id_result = $this->comment_model->tree_all($ne_id); foreach ($id_result $comment_id) { array_push($store_all_id, $comment_id['parent_id']); } //echo $this->db->last_query();exit; $this->in_parent(0,$ne_id, $store_all_id); } function in_parent($in_parent,$ne_id,$store_all_id) { if (in_array($in_parent,$store_all_id)) { $result = $this->comment_model->tree_by_parent($ne_id,$in_parent); echo $in_parent == 0 ? "<ul class='tree'>" : "<ul>"; foreach ($result $re) { echo " <li class='comment_box'>

i have trigger in database. create trigger trigg_varer_ledit_iu on items insert, update begin update items set lastedit = getdate() itemnr in (select itemnr inserted) end; it works good. every time update , insert new data items "lastedit" field updated. but: have spesific fields in table should not trigger update lastedit field. how can achieve that? now works every fields updated. need keep of them out of circus. you can use if construct check. example on updates inserted.column = deleted.column related question - compare deleted , inserted table in sql server 2008

so bit of nitty gritty question... i have time-series signal has non-uniform response spectrum need whiten. whitening using frequency time normalization method, incrementally filter signal between 2 frequency endpoints, using constant narrow frequency band (~1/4 lowest frequency end-member). find envelope characterizes each 1 of these narrow bands, , normalize frequency component. rebuild signal using these normalized signals... done in python (sorry, has python solution)... here raw data: and here spectrum: and here spectrum of whitened data: the problem is, have maybe ~500,000 signals this, , takes while (~a minute each)... entirety of time being spend doing actual (multiple) hilbert transforms i have running on small cluster already. don't want parallelize loop hilbert in. i'm looking alternative envelope routines/functions (non hilbert), or alternative ways calculate entire narrowband response function without doing loop. the other option make frequency

here code: system.out.println(" serverstarttime:" + serverstarttime + " serverrunningtime:" + serverrunningtime); timestamp stime = converttimeformat(serverstarttime, "mmm d, yyyy h:mm:ss z"); timestamp etime = converttimeformat(serverrunningtime, "mmm d, yyyy h:mm:ss z"); long diff = (etime.gettime() - stime.gettime()); system.out.println("etime.gettime():" + etime.gettime() + " stime.gettime():" + stime.gettime() + " time diff:" + diff); the converttime looks like: private timestamp converttimeformat(string msgdate, string srcdateformat) { simpledateformat sdf = new simpledateformat(srcdateformat); simpledateformat output = new simpledateformat("yyyy-mm-dd hh:mm:ss"); try { date d = sdf.parse(msgdate); string formattedtime = output.format(d); return timestamp.valueof(formattedtime); } catch (parseexception e) { e.printstacktrace(); } retu

how create keyvaluepair in log4j2 in propterties file? i know in log4j version 1 it's done like: log4j.appender.x.additionalfields={'key': 'value'} and xml way in log4j2 is: <keyvaluepair key="key" value="value"/> so way properties file this: `appender.x.keyvaluepair ={'key': 'value'}` ? this working example of how define key value pair example graylog2 (gelf) appender: appender.graylog.type=gelf appender.graylog.name=graylog appender.graylog.server=yourhostname appender.graylog.includestacktrace=true appender.graylog.additionalfields.type=keyvaluepair appender.graylog.additionalfields.key=yarncontainer appender.graylog.additionalfields.value=containerxyz

i cannot make solution work... result app crash. made listview, added items , got selected ones, miss making elements of list contacts' names instead of random ones. once selected, ask number , putextra them in activity. edit: suggested, here's code i'm trying working: cursor phones = getcontentresolver().query(contactscontract.commondatakinds.phone.content_uri, null,null,null, null); while (phones.movetonext()) { string name=phones.getstring(phones.getcolumnindex(contactscontract.commondatakinds.phone.display_name)); string phonenumber = phones.getstring(phones.getcolumnindex(contactscontract.commondatakinds.phone.number)); } phones.close(); i'll insert loop every contact, adding every time strings name , phonenumber arraylist. however, when press button should run code (and button working fine), long list of errors android monitor (here's first lines): e/androidruntime: fatal except

so, i'm trying make easter egg in calculator program, if type friend johns name in, prints nerd, keep getting invalid syntax on line if statement starts. here's code looks like: x = input(' ') if x = john: print nerd else: print x please keep in mind i'm using python 2.7, not 3. when googled it, got answers worked in 3. x = raw_input('enter name ') if x == 'john': print 'nerd' else: print x you doing assignment, need == check equality

i function in python converts string command ast (abstract syntax tree). the syntax command follows: commandname(3, "hello", 5.0, x::int) a command can accept number of comma separated values can either integers strings floats types suppose function called convert_to_ast , then convert_to_ast('commandname(3, "hello", 5.0, x::int)') should yield following ast: { 'type': 'command', 'name': 'commandname', 'args': [{ 'type': 'int', 'value': 3 }, { 'type': 'str', 'value': 'hello' }, { 'type': 'float', 'value': 5.0 }, { 'type': 'var', 'kind': 'int', 'name': 'x }] seems evaluate string , pick off types there: >>> items = ast.literal_eval('(404.5, "hello", 5)') >>> [{'type': t

i have been researching how extract title tags html. i've pretty figured out regex , html don't mix , grep can used. however, code found here , looks this: awk -vrs="</title>" '/<title>/{gsub(/.*<title>|\n+/,"");print;exit}' now, works find text between title tags once. know how can make run on every line. cat file; while read line; ...; done . however, know not efficient there's better way. secondly, in file need keep lines start string '--'. believe requires adding 'or' statement in awk match title tags , line starting '--' the input file this: text text text <title>random text of title 1</title> random html stuff --time-- xyz more random text <title>random text of title 2</title> hmtl text --time-- text <title>random text of title 3</title> more text tags --time-- text here <title>random text of title 4</title> random text html --time-- t

i know dataframes supposed immutable , , know it's not great idea try change them. however, file i'm receiving has useless header of 4 columns (the whole file has 50+ columns). so, i"m trying rid of top row because throws off. i've tried number of different solutions (mostly found on here) using .filter() , map replacements, haven't gotten work. here's example of how data looks: h | 300 | 23098234 | n d | 399 | 54598755 | y | 09983 | 09823 | 02983 | ... | 0987098 d | 654 | 65465465 | y | 09983 | 09823 | 02983 | ... | 0987098 d | 198 | 02982093 | y | 09983 | 09823 | 02983 | ... | 0987098 any ideas? the cleanest way i've seen far along lines of filtering out first row csv_rows = sc.textfile('path_to_csv') skipable_first_row = csv_rows.first() useful_csv_rows = csv_rows.filter(row => row != skipable_first_row)
