djbuild 1.0.4
Buildout recipe for Django
License: BSD

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]
  recipe = gocept.download
  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`.

download-cache
  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`.
  
find-links
  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 = {
      'method': 'threaded',
      '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 =
    http://django-command-extensions.googlecode.com/svn/trunk/ django-command-extensions
    http://django-mptt.googlecode.com/svn/trunk/ django-mptt

  [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>
