when searching django jquery uploading library, came across one. https://github.com/alem/django-jfu it seems neat , useful. so, decided give shot , started read demo code. however, highlighted line of code hard understand. in file demo/photos/views.py class home( generic.templateview ): template_name = 'base.html' def get_context_data(self, **kwargs): context = super( home, self ).get_context_data( **kwargs ) **context['accepted_mime_types'] = ['image/*']** return context if want configure able upload both pictures (.jpg, .png, etc.) , .pdf files. how shall highlighted line modified? guess 1 context['accepted_mime_types'] = ['image/* text/plain'] is correct? on other hand, photo_upload_form.html shall changed from {% block js_opts %} sequentialuploads: true, acceptfiletypes: /(\.|\/)(png|gif|jpe?g)$/i {% endblock %} to {% block js_opts %} sequentialuploads: true, acceptfiletypes: /(\.|\/)(png|g

i feel confused code this[not written me]: version = any(func1(), func2()) # wrong, should any([func1(), func2()]) def func1(): if something: return 1 else: return none def func2(): if something: return 2 else: return 3 version must num. when [func1(), func2()] [1, none] , should return 1, when [none, 2] , should return 2, when [1, 2] , should return 1. so think it's wrong use any() in code, because any() return true or false . if rewirte logic using way, can not find graceful way pythoner. i want know whether any() can achieve logic, if not, how achieve gracefully? you can use or here. version = func1() or func2() make sure functions defined before trying call them. this works because or returns first true-like value or last value (if no value true-like) . , 'none' considered false-like in boolean context.

i'm using eloquent project , delete articles. problem database complicated. there articles, have article_lvl1 , article_lvl1 have article_lvl2. when delete article event functions work fine : <?php namespace app\model; class article extends \illuminate\database\eloquent\model { public static function boot() { parent::boot(); // cause delete of product cascade children deleted static::deleting(function($article) { $article->articleniveau1()->delete(); $article->articleniveau2()->delete(); }); } public function articleniveau1() { return $this->hasmany('app\model\articleniveau1', 'id_article'); } public function articleniveau2() { return $this->hasmany('app\model\articleniveau2', 'id_article'); } protected $table = 'article'; public $timestamps = false; protected $primarykey = 'id_article'; } but article can have article_informations, can have article_date. pro

i know common error noobs myself, can't seem read can understand. homework need create array of longs called numberlist. 1 of methods need complete called tostring, turns array string print. so in main method created blank numberlist object , tried running tostring() method on it. compiler says "non-static method tostring() cannot referenced static context". why!? secondly, created test array of longs want pass numberlist object. called array testexample , made arbitrary values. when write new numberlist(testexample); i more errors. why can not this? finally here's code. please ignore every method except main, constructors, , tostring. thank much public class numberlist implements java.util.collection { //instance stuff private long[] longarray; public static void main ( string[] args ) { long[] testexample; testexample = new long[3]; testexample[0] = 1; testexample[1] = 2; testexample[2] = 3; new numberlist();

i'm trying have function return updated object after db runs update method on query right now, can't figure out how return object. function wrote using examples found, extend q.update(cat) return future[cat]. def update(id: long, cat: cat): future[unit] = db.run { val q = { c <- cats if c.id === id } yield c q.update(cat).map(_ => ()) } you should try following: def update(id: long, cat: cat): future[option[cat]] = db.run { cats.filter(_.id === id).update(cat).map { case 0 => none case _ => some(cat) } } you should return future[option[cat]] instead of future[cat] , because cat provided id might not exist (the update method returns 0 value then). violating integrity constraints result in failure of future .

i read in manual , info pages sections optimization levels in find command , cannot understand why should not use aggressive optimization level. the relevant sentences found (from man find version 4.4.2 ): conversely, optimisations prove reliable, robust , effective may enabled @ lower optimisation levels on time. the findutils test suite runs tests on find @ each optimisation level , ensures result same. if understood well, it's proofing right behaviour of find through findutils but, test suit ensures otimization levels giving same result. you're missing sentence: the cost-based optimiser has fixed idea of how given test succeed. that means if have directory highly atypical contents (e.g. lot of named pipes , few "regular" files), optimizer may worsen performance of query (in case assuming -type f more succeed -type p when reverse true). in situation this, you're better off hand-optimizing it, possible @ -o1 or -o2 .

i have indexes on 2 columns of type timestamp(2) start_date , end_date , query whare clause like: where c.start_date <= sysdate , sysdate <= c.end_date the explain plan makes table access full instead of index range scan. -if change <= = index used. -if change sysdate systimestamp it's worse in explain plan: sys_extract_utc(internal_function(c.start_date))<=sys_extract_utc(systimestamp(6)) with full scan again. -using to_timestamp brings desired index range scan: where c.start_date <= to_timestamp ('10-sep-02 14:10:10.123000', 'dd-mon-rr hh24:mi:ss.ff') , to_timestamp ('10-sep-02 14:10:10.123000', 'dd-mon-rr hh24:mi:ss.ff') <= c.end_date but need use current date. can explain why happens? edit: these simplified versions of query, same behavior appears. explain plans. explain plan select * communication c c.campaign_start_date <= sysdate , sysd

i need compute mean of set of ratings (var v_cr1 v_cr11) provided relevant control variable (var targ_i.1 targ_i.11) each rating satisfies condition (>=4 , not missing). at first attempted adjust syntax found http://stackoverflow.com/questions/12711613/loop-through-items-and-sum-items-in-spss/12794702 . this used: compute targ_vcs=0. execute. vector targ_i = targ_i.1 targ_i.11. vector targ_vc = v_cr1 v_cr11. loop #vecid = 1 11. if (targ_i(#vecid) <=4 , not missing (targ_vc((#vecid)))). compute targ_vcs= targ_vcs+ targ_vc(#vecid). end if. end loop. execute. it seems have worked provide me sum, although returns zeroes instead of missing when conditions not satisfied, can work around that. however, sum valid mean need count of valid v_cr satisfy targ_i. data has targ_i <=4 , not missing there missing v_cr (and other way around, accounted in above code), simple count won't do. i figure need either straightforward way compute mean within loop, way embed count in c

'{"value1": "0", "value2": "0", "value3": "20", "value4": "40", "value5": "string" }]}'; i wondering how content of json file "as is" displayed in console.log(); ? want exact json file. when var obj = json.parse(content); console.log(obj); or var obj = json.parse(content); console.log(obj.content); i this [object object] is there obj.all() or something? you don't parse json logged. a json is string. so only console.log(content);

i have 2 machines different cultures format mm/dd/yyyy parsed specflow (it's step argument) in 1 fails in other. i want tests culture independent. how configure specflow use cultureinfo.invariantculture parsing dates ? well, nobody answered this. solution problem edit app.config file , add <bindingculture name="en-us" /> in <specflow> config section. this forces specflow, on both machines, correctly parse mm/dd/yyyy date format.

i know 2 ways connect database divided 2 methods (method1 , method 2) connection connection; public void getconnectionmethod1() { try { class.forname("net.sourceforge.jtds.jdbc.driver"); connection = drivermanager.getconnection("jdbc:jtds:sqlserver://localhost:1433/latihan","sa","denni"); } catch (sqlexception e) { } } public void getconnectionmethod2() { try { drivermanager.registerdriver(new net.sourceforge.jtds.jdbc.driver()); connection = drivermanager.getconnection("jdbc:jtds:sqlserver://localhost:1433/latihan","sa","denni"); } catch (sqlexception e) { } } my question is; there difference between them ? method 1 uses class.forname while method 2 uses registerdriver what advantages , disadvantages between them? note : can use preparedstatement on method 2. from jdbc 4.0,java developers no longer need explicitly load jdbc drivers using

i'm having trouble accessing file while trying select on beginning characters basis... set location "/users/myuser/desktop/" set bom posix file (location & (first file of location name begins "thisfile")) tell application "preview" open bom is path/alias vs text type of thing? only system events , finder know file in file system is. finder has property desktop points desktop of current user. tell application "finder" set bom first file of desktop name begins "thisfile" tell application "preview" open (bom alias) or arbitrary posix path set location posix file "/users/myuser/desktop" text tell application "finder" set bom first file of folder location name begins "thisfile" tell application "preview" open (bom alias) the alias coercion needed because preview doesn't recognize finder file specifier objects.

suppose have file contents this, combination of config information , commands: server1 192.168.0.1 server2 192.168.0.12 file1 /home/user1/file1 upload file1 server1 ping server1 replicate server1 shutdown server1 the command pattern well-suited each of "upload", "ping", "replicate", , "shutdown" can represented command. however, still have few questions: 1. responsibility parse input? input file has necessary information files , servers are. parsing? client? receiver? invoker? 2. should parsed information stored? parsed information first 3 lines go in hashmap . according dzone's blog post , the receiver has knowledge of carry out request. so, guessing receiver 1 hashmap stored? 3. can commands return results? commands "ping" or "shutdown" should indicate happened after command executed. can these commands return values? whose responsibility parse input? each
