    <p>Folks, can you please help me with this questions.</p> <pre><code>var Module = function ( options ) { var settings = { selector: 'body', declaration: function () { return{ init: function () { console.log( 'nodule initialize' ); }, destroy: function () { console.log( ' module destroyed' ); } } } }; this.declaration = options.declaration || settings.declaration; this.selector = options.selector || settings.selector; }; var Registration = function ( options ) { this.selector = options.selector || **strong text**; this.declaration = options.declaration } app.utils.extend( Module, Registration ); var m_registration = new Registration( { declaration: function ( f ) { return { init: function () { }, destroy: function () { } } } } ); </code></pre> <p>My main questions, how i can inherit <strong>Module.selector</strong> properties in m_registration, if we haven't need quantity arguments passed when we are creating instance of <strong>Registration</strong></p> <p>My realisation of function app.utils.extend():</p> <pre><code>var app.utils.extend = function ( from, to ) { var F = function () { }; F.prototype = from.prototype; to.prototype = new F(); to.prototype.constructor = to; to.superclass = from.prototype; } </code></pre> <hr> <p><strong>Update</strong>:</p> <p>If we are using these method:</p> <pre><code>var Registration = function ( options ) { Module.call(this, { selector : options.selector }); this.declaration = options.declaration } </code></pre> <p>How we can use inheritance if we really dont know from what instance this class extended or inheritance.</p>

    2. COYou can't define a variable with dots in the name! You have to do `var app = {}; app.utils = {}; app.utils.extend = function() {...};`

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.

SQuiL has stopped working due to an internal error.

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