    <p>Hi i am a newbie to backbone. I am trying to follow <a href="http://listen-dom-events-backbone.herokuapp.com/" rel="nofollow">http://listen-dom-events-backbone.herokuapp.com/</a>. I edited the html so as to input three attributes : Name age and occupation</p> <pre><code>&lt;form id="addPerson" action=""&gt; &lt;input type="text" placeholder="Name of the person" id="name"&gt; &lt;input type="text" placeholder="Age" id="age"&gt; &lt;input type="text" placeholder="Occupation" id="occ"&gt; &lt;input type="submit" value="Add Person"&gt; &lt;/form&gt; &lt;script id="personTemplate" type="text/template"&gt; &lt;span&gt;&lt;strong&gt;&lt;%= name %&gt;&lt;/strong&gt; (&lt;%= age %&gt;) - &lt;%= occupation %&gt;&lt;/span&gt; &lt;button class="edit"&gt;Edit&lt;/button&gt; &lt;button class="delete"&gt;Delete&lt;/button&gt; &lt;/script&gt; </code></pre> <p>And the Validation of my backbone is something like this.</p> <pre><code>App.Views.AddPerson = Backbone.View.extend({ el: '#addPerson', events: { 'submit': 'submit' }, submit: function(e) { e.preventDefault(); var newPersonName = $(e.currentTarget).find('input[type=text]').val(); var newage = $(e.currentTarget).find(age).val(); var newocc = $(e.currentTarget).find(occ).val(); var person = new App.Models.Person({name: newPersonName, age: newage, occupation: newocc}); // Only when the data exists it has to be added to the collection // This is what i tried // Method 1: var attributes = person.attributes(); validate: function(){ if(attributes.newage ==null){alert("Please Enter Age")} if(attributes.newocc ==null){alert("Please enter occupation")} } //Method 2 var attributes = person.attributes(); validate: function(attributes){ if(attributes.newage !=null){person.set({age: newage});} if(attributes.newocc !=null){person.set({occupation: newocc}); } // Only if everything above is correct this value should be returned this.collection.add(person); } </code></pre> <p>});</p> <p>Am i doing this right or there is something wrong ?</p>

    1. COI solved it this way: var newPersonName = $(e.currentTarget).find('input[type=text]').val(); var newage = $(e.currentTarget).find(age).val(); var newocc = $(e.currentTarget).find(occ).val(); if (newPersonName != ''){ if (newage != ''){ if (newocc !=''){ var person = new App.Models.Person({ name: newPersonName , age: newage, occupation: newocc}); this.collection.add(person); } } } is this the right way or is there a better way to do it ?

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.
