horizon-django contrib¶
Library built on top of Django and Horizon(part of OpenStack Dashboard) for building modern web applications.
With this toolkit is building applications blazingly fast and easy !
This library provide generic implementation most of Horizon components, add more tools for easily scaffolding applications and preserves support for complex customizations.
Short story¶
Horizon is pretty package for fast creating UI for everything. But is designed for model-less applications like an OpenStack Dashboard. If we connect Horizon with typical Django application we must create same pieces of same components and this is really suck ! We want more declarative and less imperative code. For this purpose we create this library which compose common stuff in one place.
Features¶
With Django and Conent Types
- Views - PaginatedIndex, Create, Update, Delete in Angular modal’s
- Tables with inline-ajax update
- Modal Forms autohandled
- Generic - IndexView with pagination, CRUD actions and AJAX inline-edit.
no implementation required, all Django stuff is generated automatically like an admin, but in more customizeable and extendable form.
Rest API Dashboards
- APIModel
- ClientBase - simple implementation which uses
requests
- Generic - Tables, Views, Actions
and plus all features defined under Django because if we have model most of things works well without any modification.
Manager has all responsibilty for get data from remote API. It`s simple object which has similar methods with django model managers. And it’s bound to Abstract model.

- ReactJS integration - for large tables with thousands rows we have integrated https://github.com/glittershark/reactable as
ReactTable
- tabs, templates (modal login, ...)
- set of common filters, templatetags

Contents:
Requires¶
- Django
- Horizon - part of OpenStack Dashboard
Tested with¶
- Horizon 2012+ (Icehouse +)
- Django 1.4 +
- Python 2.6 +
Installation¶
pip install horizon-contrib
pip install git+https://github.com/michaelkuty/horizon-contrib.git@develop
Configuration¶
INSTALLED_APPS += ('horizon_contrib',)
Optionaly include horizon_contrib.urls
with namespace='horizon'
. This is only for generic functionality like a index,create,update,delete views.
from django.conf.urls import patterns, include, url
urlpatterns = patterns('',
...
url(r'^contrib/', include('horizon_contrib.urls', namespace='horizon'), ),
...
)
Note
namespace
is important for url reverse
Django example¶
With Django model everythings works well without any code. Only navigate your browser to
/contrib/models/project/index
/contrib/models/project/create
/contrib/models/project/1/update
For override behaviour see doc.
Note
project
in url is model name
Horizon example REST-API !¶
Dashboard structure:
my_dashboard
|-- __init__.py
|-- projects
|-- __init__.py
|-- models.py # define data structure
|-- managers.py # load remote data
|-- panel.py # register namespace
|-- dashboard.py
Your models.py
from horizon_contrib.api import APIModel
from horizon_contrib.common import register_model
class Project(APIModel):
name = models.CharField('id', primary_key=True) # default primary is id
description = models.CharField..
...
objects = Manager() # see below
class Meta:
verbose_name = 'Project'
abstract = True
register_model(Project) # supply Django Content Type framework
New managers.py
from horizon_contrib.api import Manager
class Manager(Manager):
def all(self, *args, **kwargs):
return self.request('/projects')
Finally panel.py
from horizon_contrib.panel import ModelPanel
from horizon_redmine.dashboard import RedmineDashboard
class ProjectPanel(ModelPanel):
name = "Projects"
slug = 'projects'
model_class = 'project'
RedmineDashboard.register(ProjectPanel)
navigate your browser to /contrib/models/project/index
! or /contrib/models/project/create
Warning
This project depends on Horizon library, but isn’t in the requirements ! You may use leonardo-horizon
or openstack horizon.
