Everybody know about long spagetty-style settings file for django :-)
I tried to find any cool settings loader, but have no luck.I created this one myself.
Ok, we forgetting about `settings.py` and creating module settings (folder named settings with file `__init__.py`).
This `__init__.py` file have preloader for modules placed in settings folder and `../settings_local.py` (if exists) at the end. settings_local is awesome tool, when you use any VCS like git and have settings in vcs, but for example you have different database connection settings. You can change this settings in settings_local.
Settings splitter have variable moduleweights. This variable declares weights for selected modules to allow loader sort modules by priority and use already defined settings in each other loaded module. You can define your custom modules and weights there.
Ok, now few examples.
settings/env.py
import os
# Quick-start development settings - unsuitable for production
# See https://docs.djangoproject.com/en/1.6/howto/deployment/checklist/
DEBUG = not 'http/ask.helldude.ru/' in os.path.realpath(__file__)
settings/assets.py
# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/1.6/howto/static-files/
import os
import sys
settings = sys.modules['project.settings']
STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(settings.BASE_DIR, 'static')
STATICFILES_DIRS = (os.path.join(settings.BASE_DIR, "project/static"),)
STATICFILES_FINDERS = (
'django.contrib.staticfiles.finders.FileSystemFinder',
'django.contrib.staticfiles.finders.AppDirectoriesFinder',
'compressor.finders.CompressorFinder',
)
settings_local.py:
import sys
settings = sys.modules['project.settings']
print 'I WAS LOADED KHA KHA KHA'
if settings.DEBUG:
print 'In debug mode'
You can see amazing 'hack' there :-)
I use already defined settings via sys.modules['project.settings'] (where project is common folder for my project applications).
I hope you like this small lifehack for django settings!

Note: must call within __init__() method, so you must do self.fields["field"] = ModelChoiseField(...). This is because I did not use a ModelChoiceIterator.
A subclass of ModelChoiceField which represents the tree level of each node when generating option labels. It's limited to one level of nesting, if you need more, you should consider the django-mptt package.
For example, where a form which used a ModelChoiceField:
category = ModelChoiceField(queryset=Category.objects.all())
...would result in a select with the following options:
---------
Root 1
Root 2
Child 1.1
Child 1.2
Child 2.1
Using a NestedModelChoiceField instead:
category = NestedModelChoiceField(queryset=Category.objects.all(),
related_name='category_set',
parent_field='parent_id',
label_field='title')
...would result in a select with the following options:
Root 1
--- Child 1.1
--- Child 1.2
Root 2
--- Child 2.1
jQuery dataTables is a fantastic and powerful client-side plugin, which has many capabilities.
There are many libraries out there that easily integrate it with django with little to no effort. However, they provide everything out of the box, which isn't always the most flexible solution. I also think beginners have a lot to learn from not using already created tools.
So, finding the general examples out there lacking, I though I'd hatch out a quick example of how to very basically integrate the two.
I supply two lists at the top which define how to order the fields and which are searchable (quite similar to the one defined in the admin site) and later everything is figured from there.
Of course, for a little more complex implementation (say using a method instead of a field) this will not work (since getattr doesn't automatically call a function if it is a function), but this snippet isn't supposed to provide everything but a very basic usage example, which can be very quickly expended in any way needed.
Anyway, this snippet should work on all django versions and all dataTables versions without a hitch.
last note- I use `cStringIO` with `json.dump` out of good personal experience with that settings, though it might not be the best way to serialize the data.
Good luck, share use and enjoy, ~yuvi
