View

ARK2 provides a table driven configuration of Views on Data Schemas and Items, such as Pages, Forms and Tables. View Elements can be nested to build up complex layouts.

View Elements

View elements are either Basic Elements, or Compound Elements made up of other Basic and/or Compound Elements.

Basic Elements

  • Widget - An object embedded in a page, e.g. a form element, text element, button, etc
  • Field - A widget that is linked to a specific Attribute in a Schema and inherits its behaviour from that Attribute, e.g. an Actor's name is a text form field with defined size constraints
  • Nav - A widget that is used for site navigation, e.g. a clickable link with or without an icon

Compound Elements

  • Page - A layout of other elements in a page, with standard elements such as header, sidebar, footer, and content
  • Grid - A layout of other elements in rows and columns, both basic and compound
  • Form - An HTML5 Form
  • Table - An HTML5 Table
  • Tree - Currently not implemented, a layout of other elements in a hierarchical tree, e.g. a navigation menu

Tables

Tables are a Compound Element defined by the ARK\View\Table class, and can only embed ARK\View\Field or ARK\View\Widget Basic Elements. They cannot embed other Compound Elements. When a Table embeds Field Elements, then all Fields must belong to a single Schema, i.e. a Table embeds a Schema, with each row embedding an Item that is an instance of that Schema.

The Table Element is defined in the ark_view_table table, which is mapped by Doctrine to the ARK\View\Table class. The definition seeks to abstract the HTML5 Table definition and the currently chosen JavaScript Table widget in a generic way to avoid implementation specifics. The Twig or JavaScript frontends are expected to translate this generic definition into the specific implementation being used.
