Buildout recipe for Django

Project Description
Djangorecipe: easy install of Django with buildout
==================================================

With djangorecipe you can manage your django site in a way that is familiar to
buildout users. For example:

- ``bin/django`` to run django instead of ``bin/python manage.py``.

- ``bin/test`` to run tests instead of ``bin/python manage.py test yourproject``.
(Including running coverage "around" your test).

- ``bin/django`` automatically uses the right django settings. So you can have
a ``development.cfg`` buildout config and a ``production.cfg``, each telling
djangorecipe to use a different django settings module. ``bin/django`` will
use the right setting automatically, no need to set an environment variable.

Djangorecipe is developed on github at
https://github.com/rvanlaar/djangorecipe, you can submit bug reports there. It
is tested with travis-ci and the code quality is checked via landscape.io:

Setup
-----------

You can see an example of how to use the recipe below with some of the most
common settings::

[buildout]
show-picked-versions = true
parts =
django
eggs =
yourproject
gunicorn
develop = .
# ^^^ Assumption: the current directory is where you develop 'yourproject'.
versions = versions

[versions]
Django = 1.8.2
gunicorn = 19.3.0

[django]
recipe = djangorecipe
settings = development
eggs = ${buildout:eggs}
project = yourproject
test = yourproject
scripts-with-settings = gunicorn
# ^^^ This line generates a bin/gunicorn-with-settings script with
# the correct django environment settings variable already set.


Earlier versions of djangorecipe used to create a project structure for you,
if you wanted it to. Django itself generates good project structures now. Just
run ``bin/django startproject <projectname>``. The main directory created is
the one where you should place your buildout and probably a ``setup.py``.

Startproject creates a ``manage.py`` script for you. You can remove it, as the
``bin/django`` script that djangorecipe creates is the (almost exact)
replacement for it.

See django's documentation for `startproject
<https://docs.djangoproject.com/en/1.8/ref/django-admin/#django-admin-startproject>`_.

You can also look at `cookiecutter <https://cookiecutter.readthedocs.org/>`_.



Supported options
-----------------

The recipe supports the following options.

project
This option sets the name for your project.

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`.

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. Normally, it is
recommended that you use this option and set it to your project's name.

scripts-with-settings
Script names you add to here (like 'gunicorn') get a duplicate script
created with '-with-settings' after it (so:
``bin/gunicorn-with-settings``). They get the settings environment variable
set. At the moment, it is mostly useful for gunicorn, which cannot be run
from within the django process anymore. So the script must already be passed
the correct settings environment variable.

**Note**: the package the script is in must be in the "eggs" option of your
part. So if you use gunicorn, add it there (or add it as a dependency of
your project).

eggs
Like most buildout recipes, you can/must pass the eggs (=python packages)
you want to be available here. Often you'll have a list in the
``[buildout]`` part and re-use it here by saying ``${buildout:eggs}``.

coverage
If you set ``coverage = true``, ``bin/test`` will start coverage recording
before django starts. The ``coverage`` library must be importable. See the
extra coverage notes further below.

The options below are for older projects or special cases mostly:

dotted-settings-path
Use this option to specify a custom settings path to be used. By default,
the ``project`` and ``settings`` option values are concatenated, so for
instance ``myproject.development``. ``dotted-settings-path =
somewhere.else.production`` allows you to customize it.

extra-paths
All paths specified here will be used to extend the default Python
path for the `bin/*` scripts. Use this if you have code somewhere without a
proper ``setup.py``.

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 `[ ]`). Traditionally,
the part is called ``[django]``.

initialization
Specify some Python initialization code to be inserted into the
`control-script`. This functionality is very limited. In particular, be
aware that leading whitespace is stripped from the code given.

wsgi
An extra script is generated in the bin folder when this is set to
`true`. This is mostly only useful when deploying with apache's
mod_wsgi. The name of the script is the same as the control script, but with
``.wsgi`` appended. So often it will be ``bin/django.wsgi``.

wsgi-script
Use this option if you need to overwrite the name of the script above.

deploy_script_extra
In the `wsgi` deployment script, you sometimes need to wrap the application
in a custom wrapper for some cloud providers. This setting allows extra
content to be appended to the end of the wsgi script. For instance
``application = some_extra_wrapper(application)``. The limits described
above for `initialization` also apply here.

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



Coverage notes
--------------

Starting in django 1.7, you cannot use a custom test runner (like django-nose)
anymore to automatically run your tests with coverage enabled. The new app
initialization mechanism already loads your ``models.py``, for instance,
before the test runner gets called. So your ``models.py`` shows up as largely
untested.

With ``coverage = true``, ``bin/test`` starts coverage recording before django
gets called. It also prints out a report and export xml results (for recording
test results in Jenkins, for instance) and html results.

Behind the scenes, ``true`` is translated to a default of ``report xml_report
html_report``. These space-separated function names are called in turn on the
coverage instance. See the `coverage API docs
<http://coverage.readthedocs.io/en/latest/api.html>`_ for the available
functions. If you only want a quick report and xml output, you can set
``coverage = report xml_report`` instead.

Note that you cannot pass options to these functions, like html output
location. For that, add a ``.coveragerc`` next to your ``buildout.cfg``. See
the `coverage configuration file docs
<http://coverage.readthedocs.io/en/latest/config.html>`_. Here is an example::

[run]
omit =
*/migrations/*
*settings.py
source = your_app

[report]
show_missing = true

[html]
directory = htmlcov

[xml]
output = coverage.xml



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>

Corner case: there is a problem when several wsgi scripts are combined in a
single virtual host instance of Apache. This is due to the fact that Django
uses the environment variable DJANGO_SETTINGS_MODULE. This variable gets set
once when the first wsgi script loads. The rest of the wsgi scripts will fail,
because they need a different settings modules. However the environment
variable DJANGO_SETTINGS_MODULE is only set once. The new `initialization`
option that has been added to djangorecipe can be used to remedy this problem
as shown below::

[django]
settings = acceptance
initialization =
import os
os.environ['DJANGO_SETTINGS_MODULE'] = '${django:project}.${django:settings}'


Generating a control script for PyDev
---------------------------------------------------

Running Django with auto-reload in PyDev requires adding a small snippet
of code::

import pydevd
pydevd.patch_django_autoreload(patch_remote_debugger=False, patch_show_console=True)

just before the `if __name__ == "__main__":` in the `manage.py` module (or in
this case the control script, normally ``bin/django``, that is generated). The
following example buildout generates two control scripts: one for command-line
usage and one for PyDev, with the required snippet, using the recipe's
`initialization` option::

[buildout]
parts = django pydev
eggs =
mock

[django]
recipe = djangorecipe
eggs = ${buildout:eggs}
project = dummyshop

[pydev]
<= django
initialization =
import pydevd
pydevd.patch_django_autoreload(patch_remote_debugger=False, patch_show_console=True)


Example usage of django-configurations
--------------------------------------

django-configurations (http://django-configurations.readthedocs.org/en/latest/)
is an application that helps you organize your Django settings into classes.
Using it requires modifying the manage.py file. This is done easily using the
recipe's `initialization` option::

[buildout]
parts = django
eggs =
hashlib

[django]
recipe = djangorecipe
eggs = ${buildout:eggs}
project = myproject
initialization =
# Patch the manage file for django-configurations
import os
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myproject.settings')
os.environ.setdefault('DJANGO_CONFIGURATION', 'Development')
from configurations.management import execute_from_command_line
import django
django.core.management.execute_from_command_line = execute_from_command_line


Changes
=======


2.2.1 (2016-06-29)
------------------

- Bugfix for 2.2: ``bin/test`` was missing quotes around an option. [reinout]


2.2 (2016-06-29)
----------------

- Added optional ``coverage`` option. Set it to ``true`` to automatically run
coverage around your django tests. Needed if you used to have a test runner
like django-nose run your coverage automatically. Since django 1.7, this
doesn't work anymore. With the new "coverage" option, ``bin/test`` does it
for you. [reinout]

- Automated tests (travis-ci.org) test with django 1.4, 1.8 and 1.9 now. And
pypi, python 2.7 and python 3.4. [reinout]

2.1.2 (2015-10-21)
------------------

- Fixed documentation bug: the readme mentioned ``script-with-settings``
instead of ``scripts-with-settings`` (note the missing ``s`` after
``script``). The correct one is ``script-with-settings``.
[tzicatl]


2.1.1 (2015-06-15)
------------------

- Bugfix: ``script-entrypoints`` entry point finding now actually works.


2.1 (2015-06-15)
----------------

- Renamed ``script-entrypoints`` option to ``scripts-with-settings``. It
accepts script names that would otherwise get generated (like ``gunicorn``)
and generates a duplicate script named like ``bin/gunicorn-with-settings``.

Technical note: this depends on the scripts being setuptools "console_script
entrypoint" scripts.


2.0 (2015-06-10)
----------------

- Removed project generation. Previously, djangorecipe would generate a
directory for you from a template, but Django's own template is more than
good enough now. Especially: it generates a subdirectory for your project
now. Just run ``bin/django startproject <projectname>``.

See django's documentation for `startproject
<https://docs.djangoproject.com/en/1.8/ref/django-admin/#django-admin-startproject>`_.

You can also look at `cookiecutter <https://cookiecutter.readthedocs.org/>`_.

This also means the ``projectegg`` option is now deprecated, it isn't needed
anymore.

- We aim at django 1.7 and 1.8 now. Django 1.4 still works, (except that that
one doesn't have a good startproject command).

- Gunicorn doesn't come with the django manage.py integration, so ``bin/django
run_gunicorn`` doesn't work anymore. If you add ``script-entrypoints =
gunicorn`` to the configuration, we generate a ``bin/django_env_gunicorn``
script that is identical to ``bin/gunicorn``, only with the environment
correctly set. **Note: renamed in 2.1 to ``scripts-with-settings``**.

This way, you can use the wsgi.py script in your project (copy it from the
django docs if needed) with ``bin/django_env_gunicorn yourproject/wsgi.py``
just like suggested everywhere. This way you can adjust your wsgi file to
your liking and run it with gunicorn.

For other wsgi runners (or programs you want to use with the correct
environment set), you can add a full entry point to ``script-entrypoints``,
like ``script-entrypoints = gunicorn=gunicorn.app.wsgiapp:run`` would be the
full line for gunicorn. Look up the correct entrypoint in the relevant
package's ``setup.py``.

Django's 1.8 ``wsgi.py`` file looks like this, see https://docs.djangoproject.com/en/1.8/howto/deployment/wsgi/::

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "yourproject.settings")

application = get_wsgi_application()


- The ``wsgilog`` option has been deprecated, the old apache mod_wsgi script
hasn't been used for a long time.

- Removed old pth option, previously used for pinax. Pinax uses proper python
packages since a long time, so it isn't needed anymore.



1.11 (2014-11-21)
-----------------

- The ``dotted-settings-path`` options was only used in management script. Now
it is also used for the generated wsgi file and the test scripts.


1.10 (2014-06-16)
-----------------

- Added ``dotted-settings-path`` option. Useful when you want to specify a
custom settings path to be used by the ``manage.main()`` command.

- Renamed ``deploy_script_extra`` (with underscores) to
``deploy-script-extra`` (with dashes) for consistency with the other
options. If the underscore version is found, an exception is raised.


1.9 (2014-05-27)
----------------

- ``bin/test`` now passes along command line arguments to the underlying
management command. Previously, only the equivalent of ``manage.py test
list_of_apps`` would be done. Now command line arguments are passed as-is
after the list of apps.

- Added ``deploy_script_extra`` option. It is appended to the wsgi script.
Useful for instance for a cloud hoster where you need to wrap your wsgi
application object in a custom call.


1.8 (2014-05-27)
----------------

- Supporting buildout's relative-paths setting now.


1.7 (2013-12-11)
----------------

- Add option to change the wsgi script name. Thanks hedleyroos (Fixes pull #74)

1.6 (2013-10-28)
----------------

- Djangorecipe works with django 1.6 now.

- Tested with Django 1.4, 1.5 and 1.6. Pre-1.4 support is gone, now. Also
tested on Python 2.6/2.7, 3.2/3.3.

- Moved to buildout 2 support only.

- Removed generation of fastcgi script. You can run it easily as ``bin/django
runfcgi`` and it will be deprecated in Django 1.7 anyway.


1.5 (2013-01-25)
----------------

- Removed support for a different python version than the one you use to run
buildout with. Previously, you could run your buildout with 2.6 but get
Django to use 2.7 instead. zc.buildout 2.0 doesn't allow it anymore, so we
removed it too.


1.4 (2013-01-15)
----------------

- Added initialization code support. Thanks to anshumanb, jjmurre. (Closes #58).


1.3 (2012-09-07)
----------------

- Removed deprecation warning in Django 1.4. Fixes #49, thanks Shagi.

- Added documentation for use with mr.developer. Thanks shagi (closes issue #45)

- Added Travis support.


1.2.1 (2012-05-15)
------------------

- Fixed broken 1.2 release (missing ``*.rst`` files due to a recent txt-to-rst
rename action).


1.2 (2012-05-14)
----------------

- Removed location path from recipe. Thanks bleskes (fixes issue #50).

1.1.2
-----

- Added correct url to the deprecation warning

1.0
---

- Stable release with a real 1.0 version.
- Made djangorecipe more pep08 compliant.

0.99
----

- Djangorecipe now depends on Django. The use of the `version =` statement
is deprecated. Specify the django version in the
`[versions]` section. Install django via mr.developer if you need to use
an svn/git/hg repository. For other uses
Versionpin djangorecipe to 0.23.1 if you don't want to upgrade.
Thanks to Reinout van Rees for help with this release.

- Removed subversion and download support.

0.23.1
------

- Added a missing 'import os'

0.23
----

- Support for settings/urls boilerplate for django 1.2 and django 1.3.
It defaults to 1.3 when the version isn't 1.2.

0.22
----

- Added support for svn urls with spaces. Thanks to Brad103 (fixes #537718).

- Updated code and buildout to use newest zc.recipe.egg,
zc.recipe.testrunner and python-dateutil.

0.21
----

- The admin url is now configured for django 1.1 or higher. Thanks to
Sam Charrington (fixes #672220).

- Bootstrap.py updated (fixes #501954).

0.20
----

- The recipe know makes the `django` package know to setuptools during install.
This closes #397864. Thanks to Daniel Bruce and Dan Fairs for the patch.

- Fixed #451065 which fixes a problem with the WSGI log file option.

- Added the posibilty to configure more FCGI related settings. Thanks to Vasily
Sulatskov for the patch.

0.19.2

- The generated WSGI & FCGI scripts are now properly removed when
options change (fixes #328182). Thanks to Horst Gutmann for the
patch.

- Scripts are now updated when dependencies change. This fixes #44658,
thanks to Paul Carduner for the patch.

0.19.1
------

- Applied fix for the change in WSGI script generation. The previous
release did not work properly.

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

----

- 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.
