  1. POemberjs - strange workaround for filtering based on controller property
    text
    copied!<p>I am trying to figure out why filtering on a controller's property directly is not working as expected.</p> <p>controller:</p> <pre><code>var VideoIndexController = Em.ArrayController.extend({ genreFilter: "", actions: { filterGenre: function(genre) { this.set("genreFilter", genre); } }, genres: function() { var genres = this.get('content').map(function(video) { return video.get("GenreName");; }).filter(function(genre, index, arr) { return arr.indexOf(genre) == index; }); console.log("genres", genres); return genres }.property("content"), filteredContent: function() { var content = this.get("arrangedContent"); if (!Ember.isEmpty(this.get("genreFilter"))) { return content.filterBy("GenreName", this.get("genreFilter").valueOf()); } else { return content; } }.property("arrangedContent", "genreFilter") }); </code></pre> <p>console.log for genres:</p> <pre><code>["Youth/Children", "Movies", "Actuality/Information", "Series", "Shows", "Sport", nextObject: function, firstObject: undefined, lastObject: undefined, contains: function, getEach: function…] 0: "Youth/Children" 1: "Movies" 2: "Actuality/Information" 3: "Series" 4: "Shows" 5: "Sport" __ember1384338760148_meta: Meta _super: undefined length: 6 __proto__: Array[0] </code></pre> <p>template:</p> <pre><code>{{outlet}} &lt;a href="" {{action "filterGenre"}}&gt;All&lt;/a&gt; {{#each genres}} &lt;a href="" {{action "filterGenre" this}}&gt;{{this}}&lt;/a&gt; {{/each}} &lt;a href="" {{action "sortAZ"}}&gt;A-Z&lt;/a&gt; &lt;a href="" {{action "sortZA"}}&gt;Z-A&lt;/a&gt; &lt;a href="" {{action "sortSuggested"}}&gt;Suggested&lt;/a&gt; &lt;section &gt; {{#each filteredContent}} {{#linkTo 'catchup/item' this}} &lt;div class="catchup-list-item"&gt; {{#if thumbnailUrl}} &lt;div&gt; &lt;img {{bindAttr src="thumbnailUrl"}} /&gt; &lt;/div&gt; {{/if}} &lt;div {{bindAttr class=":title validDownloadUrl::invalid"}}&gt; &lt;div&gt;{{ProgramName}}&lt;/div&gt; &lt;div&gt;{{subTitle}}&lt;/div&gt; &lt;/div&gt; &lt;/div&gt; {{/linkTo}} {{/each} &lt;/section&gt; </code></pre> <p>notice the 2nd parameter in <code>content.filter()</code></p> <p>if I call this like:</p> <p><code>content.filterBy("GenreName", this.get("genreFilter"));</code></p> <p>then the returned array is always empty.</p> <p>adding <code>.valueOf()</code> gives me the expected output. This seems pretty cumbersome and error prone.</p> <p>edit: note that I am using <code>arrangedContent</code>, as I have some snipped actions that perform sorting</p> <p>edit2: updated to include template</p> <p>edit3: added genres array console log</p>
