i've been writing game picking style webapp django , decided implement views api endpoints drf, give me more flexibility when comes frontend approaches. have basic serializers , viewsets each of models, , can browse them (excellent) browsable api. here couple: class sheetserializer(serializers.hyperlinkedmodelserializer): user = userserializer(read_only = true) league = leagueserializer(read_only = true) picks = serializers.hyperlinkedrelatedfield( source='pick_set', many=true, view_name='pick-detail', read_only = true ) class meta: model = sheet fields = ('url', 'id', 'league_week', 'user', 'league', 'picks') class gameserializer(serializers.hyperlinkedmodelserializer): class meta: model = game fields = ('url', 'home_team', 'away_team', 'week', 'home_team_score', 'away_team_score') class pickserializer(serializers.hy...

action pasteaction = new defaulteditorkit.pasteaction(); jpopupmenu popmenu = new jpopupmenu(); menuitem = new jmenuitem(); menuitem.addactionlistener(pasteaction); menuitem.addactionlistener(searchaction); menuitem.settext("paste & search"); popmenu menu shown up; on mouse right click on jtextfield pasteaction ready made. searchaction has code check if jtextfield empty or not. if not empty, search... the problem - think - pasteaction , searchaction invoked simultaneously. searchaction invoked no matter pasteaction has finished job. when searchaction invoked check jtextfield content; founds empty! how make searchaction dependent on pasteaction 's finish? one option make generic action implementation takes in list of actions take in serial. loop on list, calling 1 @ time. use new implementation , add action listener.

i getting rows access db. need check fields length. got work, problem if field comes null. check fails. how made check length (array[0] column name checked), , works: results = query.where(p => p.field<string>(array[0]).length > 10); now problem if field null. screen shot displays field coming empty , fails check. field number 25. how can make ignore nulls , still check length? you can try avoid nulls. results = query.where(p => !string.isnullorempty(p.field<string>(array[0])) && p.field<string>(array[0]).length > 10);

when pause game have pause scene. i put there 3 buttons : rateapp button backtomain button. resumegame button. what happens: rateapp button working. resumegame button working. not working : backtomain button. why? because game still pause. pausegame function func pausegame() { ispause = true self.view?.paused = true pointslabel.hidden = true boocharacter.hidden = true pausebutton.hidden = true if #available(ios 9, *) { recordbutton.hidden = true } pausescreen = skspritenode() pausescreen.name = "pausescreen" pausescreen.position = cgpointmake(self.size.width/2, self.size.height/2) pausescreen.color = uicolor.blackcolor() pausescreen.alpha = 0.9 pausescreen.size = cgsizemake(1242,2208) addchild(pausescreen) pauselable.text = "pause" pauselable.fontsize = 75 pauselable.fontname = "fut...

i writing package performs statistical analysis while handling missing values. using wonderful, life-changing function anyna added sometime after 3.0 ( commit ). added function people might want use olsonnames . so using function, package won't work on older versions of r. see 4 options dealing this. make whole package depend on r >= 3.1 in description. redefine function in source. redefine function if user using <3.1 , don't define if using >= 3.1 or make function check version each time e.g. anyna <- function(x) if(as.numeric(r.version()$minor) > 3.1){ return(anyna(x) } else { return(any(is.na(x)) } } or if(as.numeric(r.version()$minor) > 3.1){ anyna <- base::anyna } else { anyna <- function(x) any(is.na(x)) } i'm not sure second 1 work in package source code. rewrite code using any(is.na(x)) . my concrete question is there official cran preference 1 of these ? failing that, there reasons use 1 ...

i've seen question on google/so/mongo docs, , i've tried implement solution, it's not working me. have following test database: > db.test.find().pretty() { "_id" : objectid("56b4ab167db9acd913ce6e07"), "state" : "helloworld", "items" : [ { "guid" : "123" }, { "guid" : "124" }, { "guid" : "123" } ] } and want sort "guid" element of items. running sort commands yields: > db.test.find().sort( {"items.guid" : 1}).pretty() { "_id" : objectid("56b4ab167db9acd913ce6e07"), "state" : "helloworld", "items" : [ { "guid" : "123" }, { "guid" : "124" }, { "guid...
