Buildout recipe for Django

Description

Please send me feedback and comments to carlitos.kyo@gmail.com

Based on djangorecipe and code from setuptools used.

This buildout recipe can be used to create a setup for Django. It will automatically download Django and install it in the buildout’s sandbox. You can use either a release version of Django or a subversion checkout (by using trunk instead of a version number).

The directory structure is based on: http://django.es/blog/convenciones-proyecto-django/ and now for django-1.3 use previous versions for older django versions.

logs directory to handle separete logs from webserver urls into project packages used to handle differents urls for each project

You can see an example of how to use the recipe below:

[buildout]
parts = satchmo django
eggs = ipython

[satchmo]
url = http://www.satchmoproject.com/snapshots/satchmo-0.6.tar.gz
md5sum = 659a4845c1c731be5cfe29bfcc5d14b1

[django]
recipe = djbuild
version = trunk
settings = development
eggs = ${buildout:eggs} extra-paths =${satchmo:location}
project = dummyshop

Supported options

The recipe supports the following options.

apps

projects that can be installed using pypi or compressed files. No handle dependencies do it by hand using buildout, the decision was taken for these reasons:

• if dependency is a django app this should be declared into this option to install it into the extarnal-apps directory or it should be omited if the dependency was customized and it is on local-apps directory

• if dependency is not a django app this should be declared into eggs option.

To delete an application should be by hand.

project

This option sets the name for your project. The recipe will create a basic structure if the project is not already there.

external-apps

This option sets the directory where external reusable apps goes. Which do not be installed as an egg or if you don’t want install it as an egg.

local-apps

This option sets the directory where local reusable apps goes, usually put the company name for this directory, and customized apps.

projectegg

Use this instead of the project option when you want to use an egg as the project. This disables the generation of the project structure.

python

This option can be used to specify a specific Python version which can be a different version from the one used to run the buildout.

version

The version argument can accept a few different types of arguments. You can specify trunk. In this case it will do a checkout of the Django trunk. Another option is to specify a release number like 0.96.2. This will download the release tarball. Finally you can specify a full svn url (including the revision number). An example of this would be http://code.djangoproject.com/svn/django/branches/newforms-admin@7833.

settings

You can set the name of the settings file which is to be used with this option. This is useful if you want to have a different production setup from your development setup. It defaults to development.

Set this to a folder somewhere on you system to speed up installation. The recipe will use this folder as a cache for a downloaded version of Django.

extra-paths

All paths specified here will be used to extend the default Python path for the bin/* scripts.

pth-files

Adds paths found from a site .pth file to the extra-paths. Useful for things like Pinax which maintains its own external_libs dir.

control-script

The name of the script created in the bin folder. This script is the equivalent of the manage.py Django normally creates. By default it uses the name of the section (the part between the [ ]).

test

If you want a script in the bin folder to run all the tests for a specific set of apps this is the option you would use. Set this to the list of app labels which you want to be tested.

testrunner

This is the name of the testrunner which will be created. It defaults to test.

used to install apps

All following options only have effect when the project specified by the project option has not been created already, on the setting file especified.

FCGI specific settings

Options for FCGI can be set within a settings file (settings.py). The options is FCGI_OPTIONS. It should be set to a dictionary. The part below is an example:

FCGI_OPTIONS = {
'daemonize': 'false',
}

Another example

The next example shows you how to use some more of the options:

[buildout]
parts = django extras
eggs =
hashlib

[extras]
recipe = iw.recipe.subversion
urls =

[django]
recipe = djbuild
version = trunk
settings = development
project = exampleproject
wsgi = true
eggs =
${buildout:eggs} test = someapp anotherapp Example using .pth files Pinax uses a .pth file to add a bunch of libraries to its path; we can specify it’s directory to get the libraries it specified added to our path: [buildout] parts = PIL svncode myproject [PIL] recipe = zc.recipe.egg:custom egg = PIL find-links = http://dist.repoze.org/ [svncode] recipe = iw.recipe.subversion urls = http://svn.pinaxproject.com/pinax/tags/0.5.1rc1 pinax [myproject] recipe = djbuild version = 1.0.2 eggs = PIL project = myproject settings = settings extra-paths =${buildout:directory}/myproject/apps
${svncode:location}/pinax/apps/external_apps${svncode:location}/pinax/apps/local_apps
pth-files     = \${svncode:location}/pinax/libs/external_libs
wsgi          = true

Above, we use stock Pinax for pth-files and extra-paths paths for apps, and our own project for the path that will be found first in the list. Note that we expect our project to be checked out (e.g., by svn:external) directly under this directory in to ‘myproject’.

Example with a different Python version

To use a different Python version from the one that ran buildout in the generated script use something like:

[buildout]
parts = myproject

[special-python]
executable = /some/special/python

[myproject]
recipe        = djbuild
version       = 1.0.2
project       = myproject
python        = special-python

Example configuration for mod_wsgi

If you want to deploy a project using mod_wsgi you could use this example as a starting point:

<Directory /path/to/buildout>
Order deny,allow
Allow from all
</Directory>
<VirtualHost 1.2.3.4:80>
ServerName      my.rocking.server
CustomLog       /var/log/apache2/my.rocking.server/access.log combined
ErrorLog        /var/log/apache2/my.rocking.server/error.log
WSGIScriptAlias / /path/to/buildout/bin/django.wsgi
</VirtualHost>
