<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}} <a href="" {{action "filterGenre"}}>All</a> {{#each genres}} <a href="" {{action "filterGenre" this}}>{{this}}</a> {{/each}} <a href="" {{action "sortAZ"}}>A-Z</a> <a href="" {{action "sortZA"}}>Z-A</a> <a href="" {{action "sortSuggested"}}>Suggested</a> <section > {{#each filteredContent}} {{#linkTo 'catchup/item' this}} <div class="catchup-list-item"> {{#if thumbnailUrl}} <div> <img {{bindAttr src="thumbnailUrl"}} /> </div> {{/if}} <div {{bindAttr class=":title validDownloadUrl::invalid"}}> <div>{{ProgramName}}</div> <div>{{subTitle}}</div> </div> </div> {{/linkTo}} {{/each} </section> </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>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
