Deploying like a boss

put all the commands in the section "Requirements" in a script. run it.

Running on your own computer

Requirements

You need Python >= 3.3 (IMPORTANT! previous versions do not support some critical unicode string features) with pip, and git. Then run:

cd
git clone [email protected]:tapetersen/aksite.git
cd aksite
pip install virtualenv
virtualenv ~/.virtualenvs/aksite
source ~/.virtualenvs/aksite/bin/activate
pip install -r requirements.txt

Uploading to openshift

Download the secret keys::
rhc env list -a aksite3 > env.txt

You need an account at openshift.org and to be added to the altekamereren app.

Setting up the db

You have several options when it comes to selecting which database for django to use in your developement environment. In the two sections below are instructions for setting up a PostgreSQL server and a solution using SQLite3 respectively.

Using postgreSQL on the local machine

to enable us to connect to the database, run:

rhc port-forward -a aksite3

This command starts a service that will enable port forwarding, so that a port on your local machine will automatically forward all incoming traffic to the corresponding port on the server

To connect to the db and dump its contents in the file db/data.sql, run::
pg_dump aksite3 -h localhost -p PORT -U USER -f db/data.sql

where PORT is the port specified in the table printed by rhc port-forward command above and USER is the username provided under the posgresql tab on the openshift control panel (on the openshift website)

Restore to a local db(note that this will depend on YOUR specific setup) by issuing the command::
psql -U LOCALUSER -d DATABASE -f db/data.sql

where LOCALUSER is a database user that has the necessary permissions and DATABASE is your database's name

for more information on setting up a local database server on ubuntu for development purposes, see Ubuntu Wiki[1]

then, to let django know where the database is located, run::
echo "DATABASE_URL=localhost:5432" >> env.txt

this puts a new environment variable into env.txt. the exact url will depend on your setup. it should be pretty close to this though

you will also need to define a local_settings.py file where you set the DATABASES variable according to your specific setup. Skip ahead to the section "Syncing the database with django"

Using sqlite3 on the local machine

NOTE: this approach does not work for me You can also ssh and dump the data if you want to use SQLite locally or something like that:

rhc ssh -a aksite3
cd app-root/repo/
source ../data/virtualenv/bin/activate
python manage.py dumpdata app page medialibrary auth.group auth.user sites guardian --natural --format=xml > data.xml

NOTE: putting the above in a script "dump" in db folder Transfer it in some way (please write how here if you do) and run locally:

python manage.py loaddata data.xml

Syncing the database with django

To test that the DATABASES variable is set up correctly, running the following command should connect to the database using that database's command line client:

python manage.py dbshell

You are now ready to sync your database with the django framework. Run (ignore the error about auth_permission after the first command):

python manage.py syncdb
python manage.py migrate
python manage.py syncdb

Running the server

To run the server and test your brand new developement environment::
python manage.py runserver

fire up a browser and go to the address that the server is started on(most likely: localhost:8000)

A brief note on virtualenv

if you completed this readme step-by-step you should now have a prompt that looks similar to this: (aksite)axel@axel-thinkpad:~/aksite$

the parenthesis in the beginning means that you are now inside the virtual environment 'aksite'. to get out of it and return to your normal shell, simply run the command:

deactivate

the command is only available when inside a virtual environment

to re-enter the virtual environment (i.e when coding on this website) run::
source ~/.virtualenvs/aksite/bin/activate

protip: put this command in a script or alias it

Congratulations! your environment is now properly configured

Happy hacking!
