Skeleton for Nelen & Schuurmans projects

Project description

Django code skeletons

nensskel provides so-called “paster templates” so you can easily create new Django applications, websites and python libraries. They’re not fully generic, as they originated within one company (see below).

The nensskel script creates a directory structure for you with (some partially filled) basic files (like a README.rst and a

Call the nensskel script to get usage information.

Installation is straightforward with easy_install:

$ easy_install nensskel

or with pip:

$ pip install nensskel

(Probably you need to run it with sudo on osx/linux).

Don’t forget to update from time to time:

$ easy_install --upgrade nensskel

Available templates

Three nens-specific templates are included:

  • nens_library: A buildout for nens libraries

  • nens_djangoapp: A buildout for nens Django applications

  • nens_lizardsite: A buildout for nens lizard Django sites


Nensskel originates at Nelen & Schuurmans. We set it up the way we like it and we change it the way we like it so it might not fit your case 100%.

But it does provide a good example to give you a head start with a completely setup Django application/site. For example, the Django sites come with a full-blown nginx config and Django-staticfiles is included for easy css/js setup.

If the available templates don’t serve your need, you can do two things:

  • Clone the repository and edit the template as you like; possibly submit a pull request

  • Make your own template

Drop us a line if you need help.

Example for your own skeleton

When you want to create your own skeleton, nensskel can be a nice, small example. Just download the .tar.gz and unpack it.

Do the regular python && bin/buildout and you’re good to go. The nensskel and paster scripts are created in the bin/ directory.

There is one python script in nensskel/*.py per template. The actual templates are in nensskel/templates/*. See for some documentation on what paster can do. If you want elaborate examples: is the most elaborate set of templates available.

Development and issue tracker

Nensskel is developed on github: .

Changelog for nensskel

1.36.1 (2015-09-19)

  • Update packages mitigating the ‘ValueError: too many values to unpack’.

  • Updated versions, using new lizard5 KGS. You can just as well remove the ‘extends’ line for your own projects, but at least for testing nensskel, I’m keeping it in for now. [reinout]

  • Fixed djangorecipe setup. Deprecated options have been removed (fixes #12). [reinout]

  • Using file and the new djangorecipe scripts-with-settings option: this fixes the gunicorn (and celery) setup for modern django/gunicorn combinations. [reinout]

  • Improved tests so that more buildout failures show up (like the necessary djangorecipe changes from the previous point). The test setup now also includes integration for coverage reports. [reinout]

1.35 (2015-01-21)

  • Unpinned buildout default version. Updated

1.34 (2014-10-06)

  • Updated everything for django 1.6 (regarding imports) and buildout 2.x.

  • Added the new leansite template (also removed it again).

  • Removed the deprecated GZipMiddleware from Django settings for all templates.

1.33 (2013-05-02)

  • Corrected sentry/raven setup.

  • Prepare django apps and sites to be translatable with Transifex.

1.32 (2013-02-18)

  • Bugfix: there was still a buildout-versions in the lizardsite template.

1.31 (2013-02-15)

  • Upgraded nensskel’s own setup to buildout 2.0.

  • Updated nose/coverage test setup in the generated projects and in ourselves.

  • Added pydev support also to lib/djangoapp buildouts instead of only to the site buildout.

  • Updated lizardsite demo fixture to the latest lizard-wms.

1.30 (2013-02-11)

  • Added buildout 2.0!

  • Added a django-session-cleanup-cronjob part for production and staging, which cleans old sessions in the database.

  • Added nose coverage report setup. And included mock by default.

  • Added __future__ imports everywhere for print statements and unicode. Everywhere except django settings, btw, as that weirdly breaks the testrunner!

1.29 (2012-10-11)

  • The library buildout.cfg now also extends the latest KGS; this prevents problems with mismatched buildout versions.

1.28 (2012-10-11)

  • Fixed license header (small tweak only: it pointed to LICENSE.txt instead of the .rst one).

  • Added max log size of 10MB to the logrotate script in the lizard site template.

1.27 (2012-09-24)

  • Added lizard-wms (and lizard-maptree) to the lizardsite template. Almost every site needs them and it makes the empty site more suited for demo purposes and experimenting.

1.26 (2012-06-28)

  • Fixed small issues in the lizardsite template:

    • Added auto-checkout plus explanation to its buildout config.

    • Generated random password for the production/staging databases.

    • Using site name as database name.

1.25 (2012-06-26)

  • Git instructions are now printed after generating the project (if we’re not generating an svn project). It assumes nens/lizardsystem github URLs (which you can change, of course).

  • Added more example imports to and, for instance the ugettext/ugettext_lazy import. And the lizard-ui and lizard-map base class based views.

  • Added example class based view configuration in

  • Added

  • Added the from __future__ import unicode_literals import to use unicode everywhere.

  • Updated .gitignore: we now ignore the nginx config files instead of the not-used-anymore apache ones.

1.24 (2012-06-19)

  • Added nensskel version number to the generated ‘initial generation’ changelog entry.

  • Removed TODO.rst from all the templates. We don’t actually use it.

  • Added configuration for testing on travis.

  • Using url() instead of tuples in the url patterns again. Plus fixed syntax error there.

  • Updated lizardsite skeleton to latest server configuration and fabfile.

  • Added, staging.cfg

  • Made tests work

1.22 (2011-12-08)

  • Added a templates/ subdirectory to the djangoapp.

  • Renamed media/ dir in djangoapp to static/ to match Django 1.3.

1.21 (2011-11-15)

  • Using latest and greatest server setup. Including nginx and sitesetup.

1.20 (2011-10-21)

  • Added MEDIA_URL and MEDIA_ROOT to the djangoapp template. The debugmode urlpatterns loaded in fail with a traceback otherwise.

1.19 (2011-10-18)

  • Updated the .coveragerc to be more complete.

1.18 (2011-10-18)

  • Not git-ignoring *.mo files by default: django doesn’t compile them on the fly, so they need to be included with the source code.

  • Using ‘graft’ option in the to just include everything in our project directory. .pyc/pyo files are excluded anyway, so this is more or less OK.

1.17 (2011-09-30)

  • Important bugfix: the “hidden” .something files weren’t being generated. They are now.

1.16 (2011-09-09)

  • Added git ignore file and basic to the templates.

  • Removed unneeded lizard-ui middleware as django 1.3’s logging handles it.

  • Adjusted context processors to django 1.3’s default list.

  • Added logging setup for sentry in the lizard site template.

  • Cleaned up the from djangoapp.

1.15 (2011-08-25)

  • Added the KGS to djangoapp and sites and updated for django 1.3.

  • Removed map_settings from lizardsite

  • Commented out wsgiimmportscript in apache conf (it gives an error).

  • Added lizard-map context processor (outcommented) in lizardsite

1.14 (2011-05-30)

  • Adding deadlock-timeout and especially display-name to the wsgi config. The deadlock might help with shapefiles clogging up the server. The display-name shows you which server is actually using up the CPU/mem instead of just showing ‘apache2’.

1.13 (2011-05-23)

  • Re-release of 1.12 as that download tarball was broken.

  • Adding django.contrib.gis to the INSTALLED_APPS lists as that’s needed for south migrations of geo fields.

  • nens_djangoapp’s was missing an import os.

1.12 (2011-04-13)

1.10 (2011-03-31)

  • Adding mostly-empty READMEs to the two empty ‘fixtures’ and ‘media/+package+’ dirs in the django app template. On some machines, the empty directories were not getting created. This way they are.

  • Svn-ignoring the doc/build directory (with sphinx output).

  • Added svn revert instructions for in the website template (in addition to removing the file).

1.9 (2011-03-02)

  • Small restructured text heading level fixes for the sphinx documentation.

1.8 (2011-02-01)

  • Removed buildout usage part from the readme.rst as it gets repeated lots of times all over the place this way.

  • Added matplotlib tweaks to the django site

  • Added django-extensions to the standard dependencies of django apps so that we can get a model graph.

1.7 (2011-01-19)

  • Added sphinx setup. Also swapped the .txt files for .rst ones.

1.6.1 (2010-12-03)

  • Fixed too-restrictive regex in apache’s openlayers AliasMatch: the openlayers css/icons now also work in the root of the site…

1.6 (2010-12-03)

  • Added sysegg part to the buildouts.

1.5 (2010-12-03)

  • Printing .egginfo directory removal instructions.

  • Updated list of standard svn:ignores.

  • Added django gzip middleware to the lizardsite template.

  • Added lizard-ui’s traceback logging middleware to lizardsite.

  • Updated database settings to new django multiple databases style.

1.4 (2010-10-15)

  • Added setup.cfg that tells nose to output xml test reports for use with Hudson.

  • Fixes to the test setup of django_app.

1.3 (2010-10-01)

  • Added copyright notice at the top of every file including pointer to the LICENSE.txt GPL file. No, I’m not copy/pasting 10 unneeded lines of GPL boilerplate into every file.

1.2 (2010-08-25)

  • adjustments: using the 1.4.x buildout one for now.

1.1.1 (2010-08-10)

  • Documentation update.

1.1 (2010-08-10)

  • Changed test setup of djangoapp and lizardsite to match Reinout’s latest experiments :-)

  • Added django compressor settings to the lizardsite template.

0.3 (2010-03-22)

0.2 (2010-02-12)

  • Django fixes after using skeleton in real life.
