django-tools 0.24.4

miscellaneous tools for django

Miscellaneous tools for django.

existing stuff

local sync cache

Keep a local dict in a multi-threaded environment up-to-date. Usefull for cache dicts. More info, read DocString in ./local_sync_cache/local_sync_cache.py.

threadlocals middleware

For getting request object anywhere, use ./middlewares/ThreadLocal.py

Dynamic SITE_ID middleware

Set settings.SITE_ID dynamically with a middleware base on the current request domain name. Domain name alias can be specify as a simple string or as a regular expression.

more info, read ./dynamic_site/README.creole.

StackInfoStorage

Message storage like LegacyFallbackStorage, except, every message would have a stack info, witch is helpful, for debugging. Stack info would only be added, if settings DEBUG or MESSAGE_DEBUG is on. To use it, put this into your settings:

MESSAGE_STORAGE = "django_tools.utils.messages.StackInfoStorage"

More info, read DocString in ./utils/messages.py.

limit to usergroups

Limit something with only one field, by selecting:

• anonymous users

• staff users

• superusers

• ..all existing user groups..

More info, read DocString in ./limit_to_usergroups.py

DOM compare in unittests

The Problem: You can’t easy check if e.g. some form input fields are in the reponse, because the form rendering use a dict for storing all html attributes. So, the ordering of form field attributes are not sorted and varied.

The Solution: You need to parse the response content into a DOM tree and compare nodes.

We add the gread work of Gregor Müllegger at his GSoC 2011 form-rendering branch. You will have the following assert methods inherit from: django_tools.unittest_utils.unittest_base.BaseTestCase

• self.assertHTMLEqual() – for compare two HTML DOM trees

• self.assertDOM() – for check if nodes in response or not.

• self.assertContains() – Check if ond node occurs ‘count’ times in response

More info and examples in ./tests/test_dom_asserts.py.

small tools

debug_csrf_failure()

Display the normal debug page and not the minimal csrf debug page. More info in DocString here: django_tools/views/csrf.py.

upgrade virtualenv

A simple commandline script that calls pip install —-upgrade XY for every package thats installed in a virtualenv. Simply copy/symlink it into the root directory of your virtualenv and start it.

Note: Seems that this solution can’t observe editables right.

To use it, without installing django-tools:

~/$ cd goto/your_env
.../your_env/$ wget https://github.com/jedie/django-tools/raw/master/django_tools/upgrade_virtualenv.py
.../your_env/$ chmod +x upgrade_virtualenv.py
.../your_env/$ ./upgrade_virtualenv.py

This script will be obsolete, if pip has a own upgrade command.

..all others…

There exist many miscellaneous stuff. Look in the source, luke!

pip upgrade

To do a pip upgrade in a virtual environment, run this:

~$ cd /YourVirtualEnv/bin
~/YourVirtualEnv/bin$ source activate
(YourVirtualEnv)~/YourVirtualEnv/bin$ pip install --upgrade --verbose --editable=git+git://github.com/jedie/django-tools.git#egg=django-tools

The example used git readonly clone url. If you use subversion do this:

(YourVirtualEnv)~/YourVirtualEnv/bin$ pip install --upgrade --verbose --editable=http://svn.github.com/jedie/django-tools.git#egg=django-tools

If you have git write access, use this:

(YourVirtualEnv)~/YourVirtualEnv/bin$ pip install --upgrade --verbose --editable=[e-mail]:jedie/django-tools.git#egg=django-tools

…or just use our limit_to_usergroups.py script (see above)

fast repo update

To made a fast repository update, you can run this simple shell script:

~$ cd /path/to/django-tools
/path/to/django-tools$ ./update.sh

the update script runs “git pull origin master” or “svn update”.
