i new angular feeling lost in of it's documentation. problem: trying create button has 3 phases: add user - remove request - remove user so if want add user click on add button , sends ajax request server , if successful button should turn pending button . in pending state if click on again, request deleted , again turn add button . the third phase if user has accepted request, seeing remove user button when click on again see add button if click pending button , forth. so familiar button if you've been using social networks. when page loaded user see users , buttons each user based on it's current condition (so server handling part). part angular should handle ajax calls , changing of button per user connection request. what need: have done ajax part sending request. can't manage handle part angular needs change button it's new state (for specific user on list, meaning list has more 1 user can send connection add/pending/delete requests.) ...

i want train svm classifier image categorization scikit-learn. , want use opencv-python's sift algorithm function extract image feature.the situation follow: 1. scikit-learn's input of svm classifier 2-d array, means each row represent 1 image,and feature amount of each image same; here 2. opencv-python's sift algorithm returns list of keypoints numpy array of shape . here question is: how deal sift features fit svm classifier's input? can me ? update1 : thanks pyan's advice, i've adapt proposal follow: 1. sift feature vectors each image 2. perform k-means clustering on vectors 3. create feature dictionary, a.k.a. cookbook, based on cluster center 4. re-represent each image based on feature dictionary, of course dimention amount of each image same 5. train svm classifier , evaluate it update2: i've gathered image sift feature vectors array(x * 128),which large, , need perform clustering on it. problem is: if use k-means , parameter c...

i have table of fixtures looks this; user_id opponent_id gameweek league_id i have results table stores result of fixture , when come in. user_id gameweek league_id result what struggling relationship between 2 , how call relationship when need it. essentially, each fixture contains 2 results; 1 user_id_result , 1 opponent_id_result (both of refer id in users table) i did in fixture model; public function userresult() { return $this->hasmany('app\models\result', 'league_id', 'league_id') ->where('user_id', $this->user_id) ->where('gameweek', $this->gameweek); } and, although worked, don't think it's quite right , did not work when called through eager loading. thanks guys. this doesn't seem database structure root of problem lies. both tables have 3 columns same thing. not inefficient confusing. at first glance, make more sense drop 3 columns in results ta...

it's first time i'm transferring app, , want release un update app received. i have questions: i tried create bundle id old 1 (com.example.app) developer center said it's not available. should use 1 or one? if use bundle, old users receive update? if should use original app bundle, how can unlock it? you want use old one. if use different bundle id (e.g., com.example.app2), users not receive update expect: itunes connect , app store treats them separate apps. my understanding wouldn't "create" new bundle id either, exist in apple's systems. should able use developer center create development and/or distribution provisioning profiles newly transferred app id, ensure id in use in xcode project. when you're ready distribute, archive product (or use build system sign app store distribution profile), , upload itunes connect using login associated itunes connect account received incoming id. this contingent upon itunes connect login ...

when user scrolls down , comes end, , still tries scroll down, arc appears. example, in whatsapp, on message window, can't scroll down if @ end , arc appears. how can in cordova mobile app ( android ) using angular.js , ionic? or name of property ? thanks in advance answer: i found property ionic framework. not want, shows there no more data after last ion-list item bouncing page. if has-bouncing attribute added ion-content, page bounce. attribute's value true default ios, don't need add it, have add android. <ion-content has-bouncing="true"> </ion-content> when scroll down, mean using on-infinite-scroll for exemple, use following function mymodel.maxitemloaded boolean false, except if loaded items. <ion-infinite-scroll ng-if="!mymodel.maxitemloaded" icon="ion-loading-c" on-infinite="loadmoredata()" distance="10" > </ion-infinite-scroll> t...

update 2 essentially, i'd pass datatable sql server, not "create it", temporary thing using: cmd.commandtext = "select * table1 inner join datatable on sample.name = datatable.name" how can pass datatable vb.net (.net 2.0) sql server in similar fashion? update 1 so i'm thinking maybe passing data text file datatable , using compare against sql server table? how go doing if @ possible? original post have table in sql server 2012 (i.e., dbo.sample1) within table there column contains names (i.e., abc01, abc02, abc03, hijk01, hijk02...) i ran vb code extract file names without extension directory on machine (i.e., abc01, abc02...) met conditions, these file names saved on separate lines within text file. is there easier convenient way of linking names on text file ones on table not show rows not on text file? figured can sit , plug in bunch of name = 'abc01'... didn't w...

i have following 2 models. class url(mongoengine.document): codes = mongoengine.listfield(mongoengine.intfield(required=true), verbose_name='codes') name = mongoengine.stringfield(max_length=255, required=true) class bytesforurl(mongoengine.document): url = mongoengine.referencefield(url) value = mongoengine.floatfield(required=true) timestamp = mongoengine.datetimefield(required=true) i need data of bytesforurl given url name within time range. how query that. bytes = mongo_models.bytesforurl.objects(timestamp__gte=from_time, timestamp__lte=to_time, ) byte in bytes: print byte.value, byte.timestamp but how pass value url. help? you can use this urls = mongo_models.url.objects.filter(name=name) bytes = mongo_models.bytesforurl.objects.filter( timestamp__gte=from_time, timestamp__lte=to_time, url__in=urls)

i reading through article on image processing in c# there bit of code in there don't because it's unsafe, , know if can made safe: public static bool invert(bitmap b) { // gdi+ still lies - return format bgr, not rgb. bitmapdata bmdata = b.lockbits(new rectangle(0, 0, b.width, b.height), imagelockmode.readwrite, pixelformat.format24bpprgb); int stride = bmdata.stride; system.intptr scan0 = bmdata.scan0; unsafe { byte * p = (byte *)(void *)scan0; int noffset = stride - b.width*3; int nwidth = b.width * 3; for(int y=0;y < b.height;++y) { for(int x=0; x < nwidth; ++x ) { p[0] = (byte)(255-p[0]); ++p; } p += noffset; } } b.unlockbits(bmdata); return true; } the line byte* p = (byte*)(void*)scan0; looks culprit, have don't understand it's doing, or how made safe. can shed light...
