djangorecipe 0.15.1

Description

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.

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 = djangorecipe
version = trunk
settings = development
eggs = ${buildout:eggs}
extra-paths =
  ${satchmo:location}
project = dummyshop

Supported options

The recipe supports the following options.

project

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

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.

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 [ ]).

wsgi

An extra script is generated in the bin folder when this is set to true. This can be used with mod_wsgi to deploy the project. The name of the script is control-script.wsgi.

fcgi

Like wsgi this creates an extra script within the bin folder. This script can be used with an FCGI deployment.

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.

All following options only have effect when the project specified by the project option has not been created already.

urlconf

You can set this to a specific url conf. It will use project.urls by default.

secret

The secret to use for the settings.py, it generates a random string by default.

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 = djangorecipe
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        = djangorecipe
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.

WARNING: The first time you run this, buildout seems to try and run the recipe before the [svncode] section checks out Pinax, and it emits a warning that it couldn’t find any pth libraries. But then it runs the [svncode] and then [myproject] and does seem to find the pth libraries, but emits the bin/myproject script without the pth libraries – as if it’s cached the previous non-libraries. If you run buildout again, it will generate them with the expanded pth locations found from the [svncode] section. This feels like a bug in buildout but I don’t undrestand it well enough to provide a work-around.

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>
