i building aviation website need store aircraft manufacturer, type , version of particular aircraft....boeing 777 300 example. here boeing manufact., 777 version , 300 model. model use is: class manufa(mod...): name=charfield .... manufact=models.foreignkey(manufact) type=models.foreignkey(type) version=models.foreignkey(version) this allows easy search problem every time have display item in search, have make 3 separate queries full name of aircraft form foreign key id....for search page 100 items...thats unimaginable number of queries.. if store these names if change version name or have edit each of rows...how solve can aircraft name same row...no second query.. you have read more of great django docs ;) https://docs.djangoproject.com/en/dev/ref/models/querysets/#select-related btw. should post full model definition

var = { b: "this"; }; = null; when removing reference object literal 'a' referencing in beginning, reference "this" removed well, or cause memory leak? do have change code this: delete a.b; = null; ? this not cause memory leak. garbage collector typically works walking set of live references, marking set of objects finds , collecting didn't see. in case neither value assigned a or literal "this" found , both eligible collection

i have main tableviewcontroller. when user tap on cell in tableview, if condition statement true, show main tableviewcontroller again(but show data on screen), , if condition false, show viewcontroller. in prepareforsegue method have this: if segue.identifier == "identifier1" { let destination = segue.destinationviewcontroller as? mainviewcontroller // destination!.x = // x variable in view controller } else if segue.identifier == "identifier2" { let destination = segue.destinationviewcontroller as? viewcontroller2 destination!.y = } also, run segue after tap on cells in tableview added this: override func tableview(tableview: uitableview, didselectrowatindexpath indexpath: nsindexpath) { tableview.deselectrowatindexpath(indexpath, animated: true) if condition true { self.performseguewithidentifier("identifier1", sender: self) } else{ self.performseguewithidentifier("identifier2", sender

when open text file , write in , @ end of program close it, lines stay in text file. when reopen program, rather writing on new set of lines, overwrites there. want keep both pieces of text, data logging. ideas on how fix this. you should use a mode, this: with open("file","a") f: f.write("something") this append file instead of overwriting it.

in sdl2 project, sdl_pollevents( sdl_event* e ) doesn't send events, , allways returns 0 , can't process events. event processing loop looks fine : sdl_event e; while( sdl_pollevent( &e ) > 0 ) { //this never reached ! printf( "recieved event %d\n", e.type ); switch(e.type) { case sdl_quit: quit = true; } } on other hand, compiles fine, drawing works, , i'm sure it's not stuck in infinite loop ( made print out message @ each frame ). i link against sdl2 , other dependencies, make gcc/g++ call sdl-config --cflags . how can fixed ? you shouldn't call sdl-config --cflags . sdl ( first version of library ), not sdl2 . somehow conflicts , stops events reaching sdl_pollevents() . remove , should work !

i automating process using c#. script below, update table set param_val = replace(param_val,'proxy430/','proxy440/') param_key = 'proxy_url'; update table set param_val = replace (param_val, '.420/', '.430/') param_val '%.420/%'; for every month, upgrade version 44 in place of 43 , 43 in place of 42 , run script. automate, i've written c# code , used below code string text = file.readalltext(filepath); text.replace(oldvale, newvalue); file.writealltext(filepath, text); but, issue can replace 1 word only. how replace 2 texts in file. in case, proxy430 should replaced proxy440 , proxy440 proxy450 in single shot. how achieve this? if call replace in right order can accomplish 2 replacements on single line. string teststring = @"update table set param_val = replace(param_val, 'proxy430/', 'proxy440/') param_key = 'proxy_url'; update table set param_v

i have double need rounded 3 decimal places. i'm not sure how accurately implement math.round. have far: double distance= math.sqrt(deltax + deltay); math.round((decimal)distance, 3); console.writeline("distance :" + distance); use return value of math.round (already noted uwe keim ) , remove decimal cast. double distance = math.sqrt(10.438295 + 10.4384534295); console.writeline("distance :" + math.round(distance, 3));

i have question regarding query. there 2 tables: objects table: ============== object id date 1 2016-03-15 2 2016-01-20 attributes table: ================= parent id attribute attributedata 1 size xl 2 size s 2 price 20 query join data this: ========================================== objet id size price 1 xl null 2 s 20 this: ========================================== objet id size price 2 s 20 a left join doesn't - because there no entry in attribute table price id1. i sorry beein such newbie on this. glad help. steffen i think conditional aggregation want: select parentid, max(case when attribute = 'size' attributedata end) size, max(case when attribute = 'price' attributedata end) price attributes group parentid; using left join do: select o.*, s.attributedata size, p.attributedata price objects o left join attributes s

i trying connect in 2 sessions same spring security user , subscribe same queue using spring 4.2.4. separate messages each session. it's easy using @sendtouser , seems it's not trivial when using simpmessagingtemplate.sendtouser(...) - every session receives messages specific other session. example @sendtouser : @controller public class testcontroller { @messagemapping("/queue/hello") @sendtouser(value = "/queue/hello", broadcast = false) public string test() { return integer.tostring(new random().nextint()); } } example simpmessagingtemplate : template.convertandsendtouser("sessionuser{id=123}", "/queue/hello", "test"); i've tried adding sessionid in headers suggested example in thread: sending-error-message-in-spring-websockets unfortunately not in version of spring. have ideas? seems setting session id in headers still works, has simpsessionid, not sessionid. assumptions

i have around 200k latitude & longitude data points. how can cluster them each clusters have latitude & longitude points strictly within radius = 1 km centroid only? i tried leadercluster algorithm/package in r eventhough specify radius =1 km not strictly enforcing i.e. give clusters lot of point 5 - 10 kms cluster centroid within same cluster. not meeting requirement. number of points in cluster can vary & not problem. is there way enforce strict radius constraint in heirarchical or clustering algorithm? looking steps & implementation in r/python. tried searching in stackoverflow couldn't find solution in r/python. how visualize cluster centroids in google maps after clustering in done? edit parameters using in elki. please verify this not clustering, set cover type of problem. @ least if looking good cover. clustering algorithm finding structure in data; looking forced quantization. anyway, here 2 strategies can try e.g. in elki: c

i have following python 2 example code want make compatible python 3: call = 'for in {1..5}; sleep 1; echo "hello $i"; done' p = subprocess.popen(call, stdout=subprocess.pipe, shell=true) line in iter(p.stdout.readline, ''): print(line, end='') this works in python 2 in python 3 p.stdout not allow me specify encoding , reading return byte strings, rather unicode, comparison '' return false , iter won't stop. this issue seems imply in python 3.6 there'll way define encoding. for now, have changed iter call stop when finds empty bytes string iter(p.stdout.readline, b'') , seems work in 2 , 3. questions are: safe in both 2 , 3? there better way of ensuring compatibility? note: i'm not using for line in p.stdout: because need each line printed it's generated , according this answer p.stdout has large buffer. you can add unversal_newlines=true . p = subprocess.popen(call, stdout=subprocess.p

i read somewhere there different between these 2 indexes groups: add key id_user (id_user,seen); add key id_user (seen,id_user); well there? if yes order should based on parameter? in reality have these 2 queries on 1 table: query1: select * mytable id_user = :id , seen null query2: select * mytable id_user = :id , timestamp > :tm so kind of indexes proper in case? have 3 separated indexed on id_user , seen , timestamp columns. both queries have equality condition on id_user . hence, either can take advantage of index id_user first key in index. so, recommend first index mention. mysql has documentation on multi-column indexes. suggest start there learn them. your query can take advantage of indexes on (id_user, seen) , (id_user, timestamp) . probably, first key important. should try different indexes , see best meet performance goals.
