cykooz.djangorecipe 1.1

Buildout recipe for Django

Description

This project is a fork of django recipe (https://launchpad.net/djangorecipe) originally created by Jeroen Vloothuis. Forked to alter for our internal workflow and directory structure.

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 see an example of how to use the recipe below:

[buildout]
parts = satchmo django
eggs = ipython
versions = versions

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

[django]
recipe = cykooz.djangorecipe
settings = development
eggs = ${buildout:eggs}
extra-paths =
  ${satchmo:location}
project = dummyshop

[versions]
Django = 1.2.5

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.

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.

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.

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 default name of the script is control-script.wsgi.

wsgi-script

The name of the wsgi script.

wsgilog

In case the WSGI server you’re using does not allow printing to stdout, you can set this variable to a filesystem path - all stdout/stderr data is redirected to the log instead of printed

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.

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',
}

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 = cykooz.djangorecipe
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        = cykooz.djangorecipe
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        = cykooz.djangorecipe
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>

• Add option wsgi-script for change default wsgi script name.

• Now, the recipe creates the file settigs.py by using the startproject command from django.

0.20

0.19

• When running again with non-newest set the recipe will no longer update the Subversion checkout. Thanks to vinilios for the patch.

• The WSGI and FCGI scripts are now generated using Buildout’s own system. This makes them more similar to the generated manage script with regard to the setup of paths. Thanks to Jannis Leidel for the patch.

0.18

• Paths from eggs and extra-paths now get precedence over the default system path (fixes #370420). Thanks to Horst Gutmann for the patch.

• The generated WSGI script now uses the python option if present. This fixes #361695.

0.17.4

• Fixed a problem when not running in verbose mode (fixes #375151).

0.17.3

• Removed dependency on setuptools_bzr since it does not seem to work like I expected.

0.17.2

• Changed the download code to use urllib2. This should make it work from behind proxies (fixes #362822). Thanks to pauld for the patch.

0.17

• Added an option to specify a log file for output redirection from the WSGI script. Thanks to Guido Wesdorp for the patch.

0.16

• Subversion aliases are now supported (something like svn+mystuff://myjunk). Thanks to Remco for the patch.

0.15.2

• Update to move pth-files finder from the __init__ method to the install method so it runs in buildout-order, else it looks for pth files in dirs that may not yet exist. Thanks to Chris Shenton for the update to his original patch.

0.15.1

• Update to make the previously added pth-files option better documented.

0.15

• Added “pth-files” option to add libraries to extra-paths from site .pth files. Thanks to Chris Shenton for the patch.

0.14

• The recipe now supports creating a FCGI script. Thanks to Jannis Leidel for the patch.

• When downloading a Django recipe for the first time the recipe now properly reports the url it is downloading from.

0.13

• Specifying a user name within a subversion url now works. The code that determined the revision has been updated. This fixes issue #274004. Thanks to Remco for the patch.

• Updated the template for creating new projects. It now uses the current admin system when generating it’s urls.py file. This fixes issue #276255. Thanks to Roland for the patch.

0.12.1

• Re-upload since CHANGES.txt was missing from the release

0.12

• The recipe no longer executes subversion to determine whether the versions is to be downloaded using subversion. This fixes issue #271145. Thanks to Kapil Thangavelu for the patch.

• Changed the pythonpath option to extra-paths. This makes the recipe more consistent with other recipes (see issue #270908).

0.11

• Another go at fixing the updating problem (#250811) by making sure the update method is always called. It would not be called in the previous version since the recipe wrote a random secret (if it wasn’t specified) to the options for use with a template. Buildout saw this as a change in options and therefore always decided to un-install & install.

• When both projectegg and wsgi=True are specified, the generated wsgi file did not have the correct settings file in it. This has been fixed with a patch from Dan Fairs.

• The recipe now has logging. All print statements have been replaced and a few extra logging calls have been added. This makes the recipe more informative about long running tasks. Thanks erny for the patch from issue #260628.

0.10

• The recipe no longer expects the top level directory name in a release tarball to be consistent with the version number. This fixes issue #260097. Thanks to erny for reporting this issue and suggesting a solution.

• Revision pinns for the svn checkout now stay pinned when re-running the buildout. This fixes issue #250811. Thanks to Remco for reporting this.

• Added an option to specify an egg to use as the project. This disables the code which creates the basic project structure. Thanks to Dan Fairs for the patch from issue #252647.

0.9.1

• Fixed the previous release which was broken due to a missing manifest file

0.9

• The settings option is fixed so that it supports arbitrary depth settings paths (example; conf.customer.development).

• The version argument now excepts a full svn url as well. You can use this to get a branch or fix any url to a specific revision with the standard svn @ syntax

• The wsgi script is no longer made executable and readable only by the user who ran buildout. This avoids problems with deployment.
