    <p>So I have a new form set up it saves temporarily and all but I want it to only be able to update when it is validated otherwise show some errors. This is during the view section for the saveEdits event Any clue as to what I am doing wrong?</p> <p>This is my main.js file</p> <pre><code>(function () { window.App = { Models: {}, Collections: {}, Views: {}, Templates: {}, Router: {} }; // MODEL App.Models.User = Backbone.Model.extend({ defaults: { firstName: 'first', lastName: 'last', email: 'Email', phone: '222', birthday: '07/22/1980' }, validate: function (attrs) { if (!attrs.firstName) { return 'You must enter a real first name.'; } if (!attrs.lastName) { return 'You must enter a real last name.'; } if (attrs.email.length &lt; 5) { return 'You must enter a real email.'; } if (attrs.phone.length &lt; 10 &amp;&amp; attrs.phone === int) { return 'You must enter a real phone number, if you did please remove the dash and spaces.'; } if (attrs.city.length &lt; 2) { return 'You must enter a real city.'; } }, initialize: function() { this.on('invalid', function (model, invalid) { console.log(invalid); }); } }); //var userModel = new App.Models.User(); //VIEW App.Views.User = Backbone.View.extend({ el: '#user', //model: userModel, //tagName: 'div', //id: 'user', //className: 'userProfile', //template: _.template($("#userTemplate").html()), //editTemplate: _.template($("#userEditTemplate").html()), initialize: function (){ }, render: function() { this.template = Handlebars.compile($("#userTemplate").html()); this.editTemplate = Handlebars.compile($("#userEditTemplate").html()); this.$el.html(this.template(this.model.toJSON())); return this; }, events: { 'click button.edit': 'editProfile', 'click button.save': 'saveEdits', 'click button.cancel': 'cancelEdits' }, editProfile: function () { this.$el.html(this.editTemplate(this.model.toJSON())); }, saveEdits: function () { var form = $(this.el).find('form#updateUser'); this.model.set({ firstName : form.find('.firstName').val(), lastName : form.find('.lastName').val(), email: form.find('.email').val(), phone: form.find('.phone').val(), birthday: form.find('.birthday').val() }); this.model.validate(); this.render(); }, cancelEdits: function() { this.render(); } }); //start history service Backbone.history.start(); var user = new App.Views.User({model: new App.Models.User()}); user.render(); })(); </code></pre> <p>It works fine until I insert the this.model.validate and an error shows up stating this: <code>Uncaught TypeError: Cannot read property 'firstName' of undefined</code> </p>

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.
