    <p>I have a Backbone View which handles a registration component, because this required a lot of form access I had the idea to store the form selectors in an object property.</p> <pre><code>define(["models/security/user", 'text!templates/security/registration.html'], function(SecurityUserModel, Template){ var SecurityRegistrationView; SecurityRegistrationView = Backbone.View.extend({ initialize: function(){ this.model = new SecurityUserModel(); this.model.bind("validated:valid", this.valid); this.model.bind("validated:invalid", this.invalid); Backbone.Validation.bind(this); this.render(); }, render: function(){ $(this.el).append(Template); }, events: { "submit form": "submit" }, form: { "username": $("#_user_username") , "email": $("#_user_email") , "password": $("#_user_password") }, submit: function(e){ e.preventDefault(); this.model.set("username", this.form.username.val()); this.model.set("password", this.form.email.val()); this.model.set("email", this.form.password.val()); this.model.validate(); // debug console.log([this.form, this.form.username.val(), this.form.email.val()]); if (this.model.isValid) { this.model.save(); } }, valid: function(model, attrs){ // error this.form.attrs[0].username.parent("div.control-group").addClass("success"); }, invalid: function(model, attrs){ // error this.form.attrs[0].username.parent("div.control-group").addClass("error"); } }); return SecurityRegistrationView; }); </code></pre> <p>When I console.log this.form, I get an object which looks quite good nothing undefined or weird:</p> <pre><code>[ Object email: e.fn.e.init[0] context: HTMLDocument selector: "#_user_email" __proto__: Object[0] password: e.fn.e.init[0] context: HTMLDocument selector: "#_user_password" __proto__: Object[0] username: e.fn.e.init[0] context: HTMLDocument selector: "#_user_username" __proto__: Object[0] __proto__: Object ] </code></pre> <p>Loggin an jquery function accessing the selectors (this.form.username.val()) fails with undefined.</p> <p>Why can't use jQuery functions on properties ($el uses this to) where is the thinking error?</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
