Massive strides have been made to allow -for the addition of new "plug-in" components and customization of OpenStack -Dashboard deployments. - -To support this extensability, all the components used to build on Horizon's -interface are now modular and reusable. Horizon's own dashboards use these -components, and they have all been built with third-party developers in mind. -Some of the main components are listed below. - -Dashboards and Panels -~~~~~~~~~~~~~~~~~~~~~ - -Horizon's structure has been divided into logical groupings called dashboards -and panels. Horizon's classes representing these concepts handle all the -structural concerns associated with building a complete user interface -(navigation, access control, url structure, etc.). - -Data Tables -~~~~~~~~~~~ - -One of the most common activities in a dashboard user interface is simply -displaying a list of resources or data and allowing the user to take actions on -that data. To this end, Horizon abstracted the commonalities of this task into a -reusable set of classes which allow developers to programmatically create -displays and interactions for their data with minimal effort and zero -boilerplate. - -Tabs and TabGroups -~~~~~~~~~~~~~~~~~~ - -Another extremely common user-interface element is the use of "tabs" to break -down discrete groups of data into manageable chunks. Since these tabs often -encompasse vastly different data, may have completely different access -restrictions, and may sometimes be better-off being loaded dynamically rather -than with the initial page load, Horizon includes tab and tab group classes for -constructing these interfaces elegently and with no knowledge of the HTML, CSS -or JavaScript involved. - -Nova Features -------------- - -Support for Nova's features has been greatly improved in Essex: - -* Support for Nova volumes, including: - * Volumes creation and management. - * Volume snapshots. - * Realtime AJAX updating for volumes in transition states. -* Improved Nova instance display and interactions, including: - * Launching instances from volumes. - * Pausing/suspending instances. - * Displaying instance power states. - * Realtime AJAX updating for instances in transition states. -* Support for managing Floating IP address pools. -* New instance and volume detail views. - -Settings --------- - -A new "Settings" area was added that offers several userful functions: - -* EC2 credentials download. -* OpenStack RC file download. -* User language preference customization. - -User Experience Improvements ----------------------------- - -* Support for batch actions on multiple resources (e.g. terminating multiple - instances at once). -* Modal interactions throughout the entire UI. -* AJAX form submission for in-place validation. -* Improved in-context help for forms (tooltips and validation messages). - - -Community ---------- - -* Creation and publication of a set of Human Interface Guidelines (HIG). -* Copious amounts of documentation for developers. - -Under The Hood --------------- - -* Internationalization fully enabled, with all strings marked for translation. -* Client library changes: - * Full migration to python-novaclient from the deprecated openstackx library. - * Migration to python-keystoneclient from the deprecated keystone portion - of the python-novaclient library. -* Client-side templating capabilities for more easily creating dynamic - interactions. -* Frontend overhaul to use the Bootstrap CSS/JS framework. -* Centralized error handling for vastly improved stability/reliability - across APIs/clients. -* Completely revamped test suite with comprehensive test data. -* Forward-compatibility with Django 1.4 and the option of cookie-based sessions. - -Known Issues and Limitations -============================ - -Quantum -------- - -Quantum support has been removed from Horizon for the Essex release. It will be -restored in Folsom in conjunction with Quantum's first release as a core -OpenStack project. - -Keystone --------- - -Due to the mechanisms by which Keystone determines "admin"-ness for a user, an -admin user interacting with the "Project" dashboard may see some inconsistent -behavior such as all resources being listed instead of only those belonging to -that project, or only being able to return to the "Admin" dashboard while -accessing certain projects. - -Exceptions during customization -------------------------------- - -Exceptions raised while overriding built-in Horizon behavior via the -"customization_module" setting may trigger a bug in the error handling -which will mask the original exception. - -Backwards Compatibility -======================= - -The Essex Horizon release is only partially backwards-compatible with Diablo -OpenStack components. While it is largely possible to log in and interact, many -functions in Nova, Glance and Keystone changed too substantially in Essex to -maintain full compatibliity. |
