working on project in laravel , want integrate vue , vue resource it. have setup not working expected. below code: routes.php route::get('api/projects', function() { return app\project::all(); }); app.js new vue({ el: '#project', data: { projects: [] }, ready: function() { this.getprojects(); }, methods: { getprojects: function() { this.$http.get('api/projects').then(function(projects) { this.$set('projects', projects); }); } } }); my view <div class="content" v-for="project in projects"> <h3 class="title"> @{{ project.title }} </h3> @{{ project.description }} </div> with code above, nothing displayed on page if i @{{ $data | json }} i projects data in json. kind of weird, please doing wrong. thanks @programmator on laracast . answer solved issue...

i have array of hash. eg) array_of_hash = [ { id: 20, name: 'john' }, { id: 30, name: 'doe'} ] i records match criteria in particular hash. query want executed is select persons.* persons persons.id = 20 , persons.name = 'john' or persons.id = 30 , persons.name = 'doe' what best way construct query array of hash? i think okay: ids = array_of_hash.map { |h| h[:id] } names = array_of_hash.map { |h| h[:name] } person.where(id: ids, name: names) (although it's not super generic) other attempt: people = person.all array_of_hash.each |h| people = people.where(h) end people # => generate long long query.

i have map of lists, each list has integers. output map of sets of elements disjoint in every other list of elements. for ex: below map of lists list 1 - 1,2,3,4,5 list 2 - 3,4,5,6,7,8 list 3 - 1,2,3,5,6,7,8 intersection of lists - 3,5 output should map of lists (excluding 3, 5) list 1 - 1,2,4 list 2 - 4,6,7,8 list 3 - 1,2,6,7,8 i have solution using 2 loops has o(n*n) complexity. trying find optimal solution. pointers appreciated. can represent different sets using hashtables. way computing overall intersection o(m) m total number of elements across sets. then, need compute set difference between original sets , computed intersection. again, done fast using hashtables o(k*n) k number of elements in overall intersection , n number of sets. the structure of algorithm use 2 non-nested loops. first compute intersection of sets, second rid of redundant elements in sets. you find running example in c++ live on coliru . #include <vector> #in...

so i'm deleting nodes database, , want retrieve nodes i've deleted far don't go looking them later. how neo4j ids of deleted nodes in java code? you can return ids of nodes you're deleting them: match (n:somelabel) delete n return id(n) however, mentioned in documentation, ids can reused neo4j, it's bad idea keep referencing them outside of transaction (not sure if that's use case).

the code below checks whether url loaded , logs console. know if there simple, clean method check if page loaded bfcache or http cache? firefox documentation states load event should not triggered if go url b , hit button url a, not experience, both load , pageshow logged regardless, know why? var tabs = require("sdk/tabs"); function onopen(tab) { tab.on("pageshow", logpageshow); tab.on("load", logloading); } function logpageshow(tab) { console.log(tab.url + " -- loaded (maybe bfcache?)

i know because of binary double representation, comparison equality of 2 double s not quite safe. need perform computation this: double a; //initializing if(a != 0){ // <----------- here double b = 2 / a; //do other computation } throw new runtimeexception(); so, comparison of double s not safe, not want to devide 0. in case? i'd use bigdecimal performance not quite acceptable. well, if issue dividing zero, news can have since if value isn't 0, can divide it, if it's really, small. you can use range comparison, comparing lowest value want allow, e.g. a >= 0.0000000000001 or similar (if it's going positive).

i need perform operation on subclass , return result: public interface ientity { } public abstract class entity : ientity { public abstract ientity dostuff(ientity e1, ientity e2, ientity e3); } public class customer : entity { public override ientity dostuff(ientity e1, ientity e2, ientity e3) { // <-- yuck var customer1 = e1 customer; // <-- yuck var customer2 = e2 customer; // <-- yuck var customer3 = e3 customer; // <-- yuck // stuff return foo; } } i want avoid subclass' method signature, , associated typecasting. so prefer this: public override customer dostuff(customer c1, customer c2, customer c3) { // stuff return foo; } how use type system accomplish that? edit: i changed name of method compare dostuff , reiterate operation irrelevant. i'm not trying compare. want change types. how do that? ...

i'm trying search keyword in rows business_type manufacturer it's not working , it's getting rows. method in model: public function search($keyword) { $this->db->like('category',$keyword); $this->db->or_like('keyword',$keyword); $this->db->or_like('products_deals_with',$keyword); $this->db->or_like('buisness_name',$keyword); $params['conditions'] = array( 'business_type' => 'manufacturer' ); $query = $this->db->get_where('business_listings', $params['conditions']); return $query->result_array(); } generated query is: select * `business_listings` `category` '%%' escape '!' or `keyword` '%%' escape '!' or `products_deals_with`like '%%' escape '!' or `buisness_name` '%%' escape '!' , `business_type` = 'manufacturer' i've found solution. i...

in page.php file, i'm aiming have different categories' loops different pages using conditioner: if (is_page(array('pagename1', 'pagename2'))) { } but when placed loop below inside 'is_page' braces, got blank page <?php $newsposts = get_posts('cat=4'); foreach($newsposts $post) : setup_postdata($post); ?> <a href="<?php the_permalink(); ?>"> <div class="col-lg-3 col-md-4 col-sm-6"> <div class="newsbox2 newsboxcolor1"> <div class="newsbox3pix boxeq"> <?php if ( has_post_thumbnail() ) { the_post_thumbnail( 'full', array() ); }else { ?> <img src="<?php echo get_bloginfo('template_directory');?>/images/noimage.jpg" alt="no image"> <?php ...

i wrote method determine distance destination along path , determine distance next waypoint along path. problem is, don't go within 10 meters of waypoint it's not getting caught having been reached. sure, increase threshold of distance make waypoint met, i'd rather come solution determine if i've passed waypoint , skip (by adding waypointsreached list) move on next one. checking see if distance location waypoint increasing instead of decreasing won't work because may stray off path before waypoint. can me wrap head around idea of way can determine if i've passed waypoint , move on next one? here's method i've written distance final destination , next waypoint. // method calculate distance destinatoin loaded route private void calculateroutetodestination(location location) { new asynctask<location, void, arraylist<double>>(){ @override protected arraylist<double> doinbackground(location... params) { ...

if have input, 51 (00110011) , index representing bit index (ex. = 0 -> 1, = 2 -> 0), how find power of 2 these examples. sorry, i'm not great math notation can give sample input , output. example: if given 51 , index 1 (001100 1 1), want function return 00010000 = 16. also, if given 173 , index 2 (10101 1 01), function must return 00001000 = 8. i'm looking solution uses bit operations , no loops based on size of number preferably. edit : isn't homework. i'm writing program stores user selections number. i'm trying challenge myself here. here little i've been able do x--; (int j = 0; j < 5; j++) { x |= x >> (int) math.pow(2, i); } x++; return x; this takes 32 bit number , returns next power of 2. i'm not sure if of use though problem. tried seeing if else had posted similar , found , thought might play in i'm trying do. edit 2 i'm having users select days of week , store days in single n...
