This django application eliminates certain annoyances in the Django framework.
- render_to decorator - Reduce typing in django views.
- signals decorator - Allow using signals as decorators.
- ajax_request decorator - Returns JsonResponse with dict as content.
- autostrip decorator - Strip form text fields before validation
- get_object_or_None function - Similar to get_object_or_404, but returns None if the object is not found.
- get_config function - Get settings from django.conf if exists, return a default value otherwise.
- AutoOneToOne field - Creates a related object on first call if it doesn't exist yet.
- JSONField - A field that stores a Python object as JSON and retrieves it as a Python object.
- HttpResponseReload - Reload and stay on same page from where the request was made.
- StaticServer middleware - Instead of configuring urls.py, just add this middleware and it will serve your static files when you are in debug mode.
- Copy the
annoyingdirectory to your django project or put in on your PYTHONPATH. - You can also run
sudo python setup.py install,sudo easy\_install django-annoying, orsudo pip install django-annoying. - Add
"annoying"under INSTALLED_APPS in yoursettings.pyfile.

Add this middleware as first item in MIDDLEWARE_CLASSES
example:
MIDDLEWARE_CLASSES = (
'annoying.middlewares.StaticServe',
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.doc.XViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
)
It will serve static files in debug mode. Also it helps when you debug one of your middleware by responding to static requests before they get to debugged middleware and will save you from constantly typing "continue" in debugger.
