Lizard-ui v.3.7


lizard-ui provides a basic Django user interface, so a base Django template and some CSS + javascript. We designed it at Nelen & Schuurmans for our geographical information websites (with water management information).Choices, requirements, assumptionsLizard-ui is opinionated: it makes choices and prescribes (good!) technologies. * Included: the blueprint css framework. It resets css styles so that we've got a common base. It fixes common IE layout bugs. It gives a basic typography that's quite pleasing. * Required: django-staticfiles. For a more verbose description, see Reinout's blog entry (written with lizard-ui in mind). * Required: django_compressor for combining css/javascript files in production. * Assumption: one screen, using the full width/height of the browser, without scrolling. Our main goal is showing a nice big map with a small header and a sidebar. You don't want to scroll a map. It is of course possible to have a scrollbar inside that main content area itself. * Assumption: javascript is available. Hey, we're showing a map so you need javascript. So we liberally use javascript to get the UI right, for instance by detecting and setting the main content area's width and height. * Included: jquery. Yeah, it is pretty much the standard nowadays. So we use jquery where jquery can be used instead of doing it with generic javascript. * Included: both jqueryui and jquerytools. Visual goodies. Jquerytools for the overlay and tabs, jqueryui for the rest (drag/drop and so). * Included: openlayers as map javascript library. (Lizard-map, sooooon to be released, contains our basic map interaction javascript and python code).Lizard-ui ships with a couple of external css/javascript libraries.Blueprint Modified MITJquery and jqueryui Dual licensed under the MIT or GPL Version 2 licenses.

The media and static root directory setup assumes the use of buildout, but you can translate it to your own filesystem setup:INSTALLED_APPS = [ 'lizard_ui', 'compressor', 'staticfiles', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', ]# Note: the below settings are more elaborate than needed,# but we want to test django_compressor's compressing which# needs a media url and root and so.# Set COMPRESS to True if you want to test compression when# DEBUG == True. (By default, COMPRESS is the opposite of# DEBUG).COMPRESS = False# SETTINGS_DIR allows media paths and so to be relative to# this settings file instead of hardcoded to# c:onlyonmycomputer.SETTINGS_DIR = os.path.dirname(os.path.realpath(__file__))# BUILDOUT_DIR is for access to the "surrounding" buildout,# for instance for BUILDOUT_DIR/var/static files to give# django-staticfiles a proper place to place all collected# static files.BUILDOUT_DIR = os.path.abspath(os.path.join(SETTINGS_DIR, '..'))# Absolute path to the directory that holds user-uploaded# media.MEDIA_ROOT = os.path.join(BUILDOUT_DIR, 'var', 'media')# Absolute path to the directory where django-staticfiles'# "bin/django build_static" places all collected static# files from all applications' /media directory.STATIC_ROOT = os.path.join(BUILDOUT_DIR, 'var', 'static')# URL that handles the media served from MEDIA_ROOT. Make# sure to use a trailing slash if there is a path component# (optional in other cases).MEDIA_URL = '/media/'# URL for the per-application /media static files collected# by django-staticfiles. Use it in templates like "{{# MEDIA_URL }}mypackage/my.css".STATIC_URL = '/static_media/'# URL prefix for admin media -- CSS, javascript and# images. Make sure to use a trailing slash. Uses# STATIC_URL as django-staticfiles nicely collects admin's# static media into STATIC_ROOT/admin.ADMIN_MEDIA_PREFIX = STATIC_URL + 'admin/'# Storage engine to be used during compressionCOMPRESS_STORAGE = ""# The URL that linked media will be read from and compressed# media will be written to.COMPRESS_URL = STATIC_URL# The absolute file path that linked media will be read from# and compressed media will be written to.COMPRESS_ROOT = STATIC_ROOT# Used for django-staticfilesTEMPLATE_CONTEXT_PROCESSORS = ( # Default items. "django.core.context_processors.auth", "django.core.context_processors.debug", "django.core.context_processors.i18n", "", # Needs to be added for django-staticfiles to allow you # to use {{ STATIC_URL }}myapp/my.css in your templates. 'staticfiles.context_processors.static_url', )And a suitable apache config hint: # The css/javascript/image staticfiles are cached in the # browser for a day. ExpiresActive On ExpiresDefault "access plus 1 day" # django_compress's generated timestamp'ed files: # cache forever ExpiresActive On ExpiresDefault "access plus 10 years"# Static files are hosted by apache itself.# User-uploaded media: MEDIA_URL = '/media/'Alias /media/ ${buildout:directory}/var/media/# django-staticfiles: STATIC_URL = '/static_media/'Alias /static_media/ ${buildout:directory}/var/static/UsageYou can mount lizard-ui's urls, but it contains only live examples. So perhaps you should only mount it in debug mode under /ui. Handy, as it contains reasonably full documentation on how to use it, including available blocks and classes/IDs that you can use.The base layout is defined in realbase.html. You should however extend lizard_ui/lizardbase.html and then override the blocks that you want.CSS and javascript should be added to the relevant blocks, but don't forget to call "block.super". An example:{% extends "lizard_ui/lizardbase.html" %}{% block css %}{{ block.super }}{% endblock css %}{% block javascript %}{{ block.super }}{% endblock javascript %}{% block content %}{% endblock content %}A example of a common task: change the logo. For that, make a media/lizard_ui directory in your django application (or site) and place a logo.png in it. Django-staticfiles' mechanism will take your logo.png in preference to lizard-ui's.Development installationThe first time, you'll have to run the "bootstrap" script to set up setuptools and buildout:$> python bootstrap.pyAnd then run buildout to set everything up:$> bin/buildout(On windows it is called binbuildout.exe).You'll have to re-run buildout when you or someone else made a change in or buildout.cfg.The current package is installed as a "development package", so changes in .py files are automatically available (just like with python develop).If you want to use trunk checkouts of other packages (instead of released versions), add them as an "svn external" in the local_checkouts/ directory and add them to the develop = list in buildout.cfg.#md5=ab207670c288327a171b93798a365830
