This tiny snippets grabs the sourcecode out of a template name without rendering or compiling the template itself.
Add's updated and created fields to a model if mixed in. Example that uses the name as the representation: class Company(models.Model, UnicodeReprMixIn): """ A representation of a comic book company. """ name = models.CharField(max_length=255) slug = models.SlugField() logo = models.ImageField(upload_to=os.path.join('upload', 'company_logos')) url = models.URLField(verify_exists=True) _unicode = "name"
This snippet prevents people from tampering with the data in hidden form fields. This is something you usually want unless you have some Javascript Vodoo going on on the browser side. For the people scratching their heads: This form class will dynamically create a clean function for every passed additional hidden field, which just returns the original value of the hidden field. So the data in the hidden field posted gets actually ignored when calling the (overwritten) clean_{field name} function. This class is just an example using the protected hidden field feature for all passed field variables, which is probably not what you want. You have to add the editable fields the end of the __init__ function in the class. Example: `self.fields['bestbeer'] = forms.CharField(max_length=23)`
Removed for now... Not sure where to share new Ellington snippets due to the gray-area of it being proprietary. It's an awesome package but it's hard to find any good help with Django 91 code. Good luck ellingtoners!

** Help me get better! If you vote (either way) please leave a comment if you have time and say what was good or bad. I appreciate any and all feedback. Thanks! ** I keep finding places in my apps where I need an isolated snippet of text that can periodically be changed from the admin interface. Most often it's html but sometimes it's text, javascript, or css. Use it like so: (Assuming this snippet lives in snippy_snip/models.py and there is a snippet named "Welcome Message" in the database) from snippy_snip.models import snip msg = snip("Welcome Message") Or, you might populate a parameter hash for a template: def showpage(request): params = { 'welcome': snip('Welcome Message'), 'video1': snip('Video 1'), 'NavHeader': snip('Nav.SectionHeader'), } return render_to_response("main.html", params) For clarity, *params* might look something like this: welcome -> "Welcome to our site. Please use the menu on the left..." video1 - > a YouTube snippet NavHeader -> Some HTML which comprises the top of a navigation menu. This is a very simple bit of code but I've found it very useful. It isn't intended for instant changes... Your snippets will cache like anything else, which may cause confusion if you expect immediate changes. And it's probably not great for a high traffic site, but for my moderate traffic sites and workgroup apps I've found it useful. (This code was created for 0.96, but I'm working to bring it into alignment with the latest svn version of Django, see comments.)
Please delete the snippet.
There has been some discussion about removing `auto_now` and `auto_now_add` some time ago. `auto_now_add` can be replaced be using a callable default value, `auto_now` can't. So I wrote this litte function for my current project (older ones still use `auto_add`) to fill the gap...but I'm not sure if `auto_now` will be removed at all.
How to make this work: * Put the code into your settings.py (or even better, local_settings.py if you have one) * Put 3rd party apps you'd like to use into the directories specified in APP_DIRS. * Place 'appname', into INSTALLED_APPS. Just a little trick I use to keep from having to install apps via setup.py; I can just stick apps into arbitrary locations and use them. I also do this to keep single copies of 3rd party apps I use in multiple projects (but again without installing to the global python path). No idea if this is bad practice or anything, but I find it useful.
I use Django's built-in development server all the time, but get tired of typing out the command to run it, and if I'm testing some custom admin css/js, I *really* get tired of typing out the command that correctly directs the middleware to use my admin media dir. So I added this alias to my .bashrc and when I'm in a project's root, I just type 'pyserver' and the development server fires up, automatically passing an --adminmedia arg if I have some custom admin media for the project (otherwise it's 'runserver' as always). Note: This relies on the convention that my custom admin media will be in a folder called admin_media that resides at the project's base. Of course, change it to whatever convention you use. I'm not a bash expert or anything, but this works for me ;)

By default extend tag don't cache parents template. This is extend tag with patch. Workaround for bug: http://code.djangoproject.com/ticket/6586
Disclaimer: I'm not the world's greatest programmer, so there may be better ways to do this, but it works for me (feel free to offer your improvements, though!). Basically, this will pad an integer with leading zeros and return a string representation. User it like this: {% forloop.counter|leading_zeros:"5" %} ...where "5" is the number of desired digits. In this case, if it was the 12th time through the forloop, the filter would return "00012". Why do this? Either for alignment, such as in tables, or for aesthetics -- for an example, see [Shaun Inman's comment section](http://shauninman.com/archive/2007/11/16/mobilesafari_view_source).
