Prep your dev environment
Install virtualbox: https://www.virtualbox.org/
Build a Linux VM from Ubuntu 12.04: http://www.ubuntu.com/
Installing the Open Data Catalog
Non-Python Dependencies
sudo apt-get update
sudo apt-get install git sendmail postgresql python postgresql-plpython-9.1 python-pip libpq-dev python-dev libxml2-dev libxslt1-dev libgeos-c1 mercurial meld
Python Dependencies
sudo pip install virtualenv
Setting up the App
Create Virtual Env
Create the shell of the virtual env and "activate" it
virtualenv opendatacatalog
cd opendatacatalog
source bin/activate
Grab the source
At this point you can grab the source from github:
git clone git://github.com/azavea/Open-Data-Catalog.git
cd Open-Data-Catalog
Or fork the code, make it better and send us a pull request!
Grab the python dependencies and do some final setup:
pip install -r requirements.txt
cd OpenDataCatalog
mkdir media
chmod 755 media
ln -s ../../lib/python2.7/site-packages/django/contrib/admin admin_media
Setting up the database
Create a new postgres db
sudo su postgres # Become the postgres user
createuser -P odc-user
psql template1 -c "CREATE DATABASE opendata OWNER \"odc-user\";"
createlang plpythonu opendata
psql -d opendata -f etc/pycsw_plpythonu.sql
exit # Exit out of the postgres user's shell
Note that running the unit tests requires that your postgres user be a super user (since it drops/creates databases). To create a user as a superuser simply do:
createuser -Ps odc-user
You can verify the connection with:
psql opendata odc-user -h localhost
Update settings
Copy local_settings.py.example to local_settings.py
Update the database settings in local_settings.py. You'll probably have to update "name", "user", "password", and "host". It should look similar to:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'opendata',
'USER': 'odc-user',
'PASSWORD': 'PASSWORD',
'HOST': 'localhost',
'PORT': '',
}
}
Open Data Catalog supports the [OGC Catalogue Service] (http://www.opengeospatial.org/standards/specifications/catalog) specification (CSW) using pycsw. CSW settings can be set/modified in settings.CSW. As well, settings.SITEHOST and settings.SITEPORT must be set accordingly for your deployment environment.
Creating the database scheme
To create the scheme we use django "syncdb" command
python manage.py syncdb --migrate
Running a server
We installed gunicorn as part of the installation process. All you need to do now is start it:
gunicorn_django
Customizing your installation
Settings
You should read OpenDataCatalog/local_settings.py for a list of configurable values, such as TWITTER_USER and SITE_ROOT. Feel free to play with these settings as much as you want.
Style
In local_settings.py you should specify a LOCAL_TEMPLATE_DIR that is the full path to your template location. As you want to change the style, you copy files out of OpenDataCatalog/templates and into your local overly directory and make the changes there. That way you can keep your repository in sync with the upstream more easily while still maintaining your own style.
Deploy to Heroku
For a quick and free deployment you can deploy directly to heroku (http://heroku.com). First make an account on the heroku website and then do the following:
Edit the .gitignore file and remove the following line:
local_settings.py
Ths will allow your personal settings from being pushed to heroku. Then:
sudo gem install heroku
heroku create --stack cedar --buildpack https://github.com/cirlabs/heroku-buildpack-geodjango/
git push heroku master
heroku run python OpenDataCatalog/manage.py syncdb
Apache
Django can run via mod_wsgi on Apache as well. Add the following to a new Apache site:
WSGIScriptAlias /hidden /<project location>/odp.wsgi
Alias /media /<project location>/media
Alias /static /<project location>/static
create /<project location>/odp.wsgi >
import os, sys
sys.path.insert(0, '/home/azavea/NPower_OpenDataPhilly')
import settings
import django.core.management
django.core.management.setup_environ(settings)
utility = django.core.management.ManagementUtility()
command = utility.fetch_command('runserver')
command.validate()
import django.conf
import django.utils
django.utils.translation.activate(django.conf.settings.LANGUAGE_CODE)
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
