ember.js - I need some ideas for this. Emberjs -

i have helper named format-log

//format-log.js import ember 'ember';  export function formatlog(text) {     var hashtag = text.match(/[#]\w+/g);     var newtext = text;     if (hashtag !== null && hashtag !== undefined) {         ( var = 0; < hashtag.length; i++){             newtext =  newtext.replace(hashtag[i], "<a href='' class='hash'>"+ hashtag[i] +"</a>");         }            return newtext;     }else{         return text;             }  }  export default ember.handlebars.makeboundhelper(formatlog); 

when make new log, have need add hashtag example

"this example #log"

that text go-through helper , returns format

"this example < href="">#log< /a>"

i wanna filter log contains same hashtag make trends twitter, using ember cli , ember-data

my model

//log.js import ds 'ember-data';  export default ds.model.extend({   text: ds.attr('string'),   date: ds.attr('date') }); 

you filter on hashtag first defining hashtags property on model return hashtags found in text, example:

//log.js import ds 'ember-data';  export default ds.model.extend({     text: ds.attr('string'),     date: ds.attr('date'),      hashtags: function() {         // return array of hash tags in text, ie ['#tag1','#tag2']         var text = this.get('text') || '';         return text.match(/#\w+/g) || [];      }.property('text') }); 

you can filter multiple log models hashtag doing (for example in controller):

modelscontainingtesttag: ember.computed.filter('logs', function(log) {     return log.get('hashtags').contains('#test'); }) 

where logs refering array of log models.

this start, example concatenate hashtags of models hashtags (using uniq() eliminate duplicates). , hashtags above filtering or sort of counter.
