Best practice based on [YSlow recommendations](http://developer.yahoo.com/yslow/), add the following to your Apache config for your media directory. <Directory /home/.../site_media/> ... FileETag None ExpiresActive on ExpiresDefault "access plus 10 years" AddOutputFilterByType DEFLATE text/css application/x-javascript </Directory` Make sure to enable mod_deflate and mod_expires.
Special thanks to all the authors of djangosnippets. It's my first contribution. Maybe the method **online_users** could be better, but for now it's working for me. Best Regards from Bolivia.
In the past, whenever I had a script that I wanted to properly configure the settings for, I would use something like the following idiom at the top of the script: import sys, os; dirname = os.path.dirname # sys.path.insert(0, dirname(dirname(__file__))) sys.path.insert(0, dirname(__file__)) os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings' Notice that this is a relative setting to `__file__` variable in the script. The djangopath function is an attempt to do away with the above such that I can now write the following: from lib import djangopath; djangopath(up=2, settings='myapp.settings') This seems to work for me, but it assumes that you are packaging your script inside your projects/apps. If they are elsewhere then you may need to resort to another method (e.g. absolute paths, etc.) AK
The venerable CustomImageField, invented by [Scott Barnham](http://scottbarnham.com/blog/2007/07/31/uploading-images-to-a-dynamic-path-with-django/) and rejiggered for newforms-admin by [jamstooks](http://pandemoniumillusion.wordpress.com/2008/08/06/django-imagefield-and-filefield-dynamic-upload-path-in-newforms-admin/#comments). This here is a stab at a [post-Signals-refactor](http://code.djangoproject.com/wiki/BackwardsIncompatibleChanges#Signalrefactoring) version. Seems to do 'er. Note: This should be pointless once [fs-refactor](http://code.djangoproject.com/ticket/5361) lands.
When you're using Django model inheritance, sometimes you want to be able to get objects of the base class that aren't instances of any of the subclasses. You might expect the obvious way of doing this, `SuperModel.objects.filter(submodel__isnull=True)`, to work, but unfortunately it doesn't. (Neither does `SuperModel.objects.filter(submodel__supermodel_ptr=None)`, or any other convoluted way I could think of doing it.) Here's a nicer approach for doing this. [The blog entry is here.](http://sciyoshi.com/blog/2008/aug/07/custom-django-manager-excludes-subclasses/)
Refactors two similar django template files to use `{% block %}` tags. Takes two template files, where one is a modified version of the other, and looks for differences and similiarities between the two. It then generates refactored (and renamed) versions of each file and a third 'base' file, adding an `{% extends %}` tag as appropriate. Block tags are named with matching numbers in all 3 files, making it easy to do a search and replace with more meaningful labels. `sample_data_in_base` controls whether or not the content from file 1 is copied into place in the base file as an example. Problems: it doesn't identify open `{% for %}` or `{% if %}` tags, so this needs some manual fixing (moving the `{% endfor %}` and `{% endif %}` tags into the proper blocks). It doesn't add the correct path for the `{% extends %}` tag either (ie. `"app/base.html"`). `collapse_whitespace` is not working at all.
Uses JSMin. Python version available from [http://www.crockford.com/javascript/jsmin.py.txt](http://www.crockford.com/javascript/jsmin.py.txt) Provides template tags to minify JavaScript on the fly. `{% minifyjs %}[code]{% endminifyjs %}`
The original USPhoneNumberField only validates xxx-xxx-xxxx values. This field validates... > (xxx) xxx xxxx > xxx-xxx-xxxx > (xxx)-xxx-xxxx > many others. **Explanation of the regular expression:** 1. Accepts either (xxx) or xxx at the start of the value. 2. Allows for any amount of dashes and spaces (including none) before the next set of digits. 3. Accepts 3 digits 4. Allows for any amount of dashes and spaces (including none) before the next set of digits. 5. Accepts 4 digits, finishing the value. This field saves in the same format that the original USPhoneNumberField does (xxx-xxx-xxxx). Enjoy!
This filter converts HTML to nicely-formatted text using the text-browser W3M. I use this for constructing e-mail bodies, since it means I don't have to have two templates, one HTML and one plain-text, for each detailed e-mail I want to send. Besides the obvious maintenance benefits, this is nice because Django's templating system isn't well-suited to plain-text where whitespace and line-breaks are significant. I chose W3M because it renders tables nicely and can take in HTML from STDIN (which Lynx can't do). An alternative is ELinks; to use it, change "cmd" to the following: `elinks -force-html -stdin -dump -no-home`
This sample site_logging.py module uses the [MODPYTHON Logging snippet](http://www.djangosnippets.org/snippets/627/). It assigns the ApacheLogHandler class to the main logging object, when Django is run inside MODPYTHON. You must have the MODPYTHON Logging snippet, and name it modpython_logging.py for this to work. Apache will write to virtual host-specific logs only with Python 2.5. Users are encouraged to change the two logging settings. Log Level: handler.setLevel(logging.WARNING) Log Format: logging.Formatter(...)
Given such code: class ProductImage(models.Model): fullsize = models.ImageField(upload_to= "products/%Y/%m/%d/") display = AutoImageField(upload_to= "products/%Y/%m/%d/",prepopulate_from='fullsize', size=(300, 300)) thumbnail = AutoImageField(upload_to="products/%Y/%m/%d/",null=True,default='/media/noimage.jpg')) display will be automatically resized from fullsize, and thumbnail will default to /media/noimage.jpg if no image is uploaded Note: At some point the code broke against trunk, which has now been updated to work properly
A custom FileSystemStorage made for normalizing extensions. It lets PIL look at the file to determine the format and append an always lower-case extension based on the results.
An example of using it in your settings.py: MIDDLEWARE_CLASSES = ( 'django.middleware.common.CommonMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.middleware.doc.XViewMiddleware', 'util.loginmiddleware.RequireLoginMiddleware', ) LOGIN_REQUIRED_URLS = ( r'/payment/(.*)$', r'/accounts/home/(.*)$', r'/accounts/edit-account/(.*)$', ) In a nutshell this requires the user to login for any url that matches against whats listing in LOGIN_REQUIRED_URLS. The system will redirect to [LOGIN_URL](http://www.djangoproject.com/documentation/settings/#login-url)
A simple addition for the urls.py that exposes the 404/500 templates during development. This way you can test how those look. They're mounted under /404/ and /505/ respectively. Add this at the bottom of your main urls.py.
Usage: from django.db import models from imagevariations.fields import ImageVariationsField, Thumbnail class Image(models.Model): name = models.CharField(max_length=20) image = ImageVariationsField(upload_to='testimages', variations=(Thumbnail,) ) How to use in templates: Use the lowercase name of the image variation class. {{ object.image.variations.thumbnail.url }} By default all image variations will use the same storage backend as the field but can be replaced per variation by setting self.storage on the variation class.
