python.org

The new www.python.org!

Getting going

Requires ✨Python 3.3!✨ (brew install python3)

You'll want a virtualenv. Python 3.3 actually includes virtualenv built-in, so you can do:

$ pyvenv-3.3 <env>
$ source <env>/bin/activate
(etc)

But you can also use your existing virtualenv/wrapper:

$ mkvirtualenv --python=python3.3 <env>

And then it's the standard:

$ pip install -r requirements.txt
$ ./manage.py syncdb

You may need to specify the pip version, even with the virtualenv activated:

$ pip-3.3 install -r requirements.txt

This expects a local database named "python.org". If you need to change it:

$ export DATABASE_URL=postgres://user:pass@host:port/dbname

To compile and compress static media, you will need compass and yui-compressor:

$ gem install bundler
$ bundle install
$ brew install yuicompressor

NOTE: On OSX you may need to adjust your PATH to be able to find the sass binary, etc.

Python 3.3 and OSX 10.8.2

Homebrew's recipe for python3.3 has some difficulty installing distribute and pip in a virtualenv. The python.org installer for OSX may work better, if you're having trouble.

Using Vagrant

You can ignore the above instructions by using Vagrant. After installing:

$ vagrant up
$ vagrant ssh

The box will be provisioned by Chef with Python 3.3, a virtualenv set up with requirements installed, and a database ready to use. The virtualenv is activated upon login. You will need to run ./manage.py createsuperuser to use the admin.

Running tests

$ pip install -r dev-requirements.txt
$ coverage run manage.py test
$ coverage report

Generate an HTML report with coverage html if you like.

Cheatsheet for Front End devs that know enough to be dangerous

But not really enough to remember all these CLI commands by heart.

Spinning up a VM

1. Open Terminal.app
2. cd ~/github/python
3. source ENV/bin/activate
4. Maybe you need to install requirements? pip install -r requirements.txt
5. export DATABASE_URL="postgres://localhost/python.org"
6. ./manage.py runserver 0.0.0.0:8000 (or whatever port you run at)

Nuke the DB!

1. Do steps 1-4 above.
2. export PATH="/Applications/Postgres.app/Contents/MacOS/bin:$PATH"
3. dropdb python.org
4. createdb python.org
5. ./manage.py syncdb
6. ./manage.py migrate
7. Install data below if you like.

Other Useful Commands

Create a super user (for a new DB): ./manage.py createsuperuser

Import calendars: ./manage.py import_ics_calendars

Want to save some data from your DB before nuking it, and then load it back in? ./manage.py dumpdata --format=json --indent=4 [app-name] > fixtures/[app-name].json

Load a specific fixture: ./manage.py loaddata fixtures/[name].json

Load all fixture files: find ./fixtures -name "*.json" -exec ./manage.py loaddata {} \;

List All the active DBs: psql -U postgres -c -l esq from window... q

If Postgres can't connect to your localhost DB, put this in pydotorg/settings/local.py:

DATABASES = {
    'default': dj_database_url.config(default='postgres://localhost:{port#}/{DBName, probably python.org}')
}

Go into PSQL and dump a DB backup:

cd /Applications/Postgres.app/Contents/MacOS/bin
./pg_dump <db_name> > path/to/file.name
./pg_dump python.org > ~/github/python/development.dump

Reload a DB dump from a file:

./pg_restore -d <db_name> <path-to-file>
./pg_restore --clean -d python.org ~/github/python/preview.dump

See here for the --clean methods http://www.postgresql.org/docs/9.2/static/app-pgrestore.html
