Adds a templatetag that works like an if block, but . The one and only argument is a float that reflects the percentage chance. It defaults to .2, %20. {% sometimes %} <img src='spy_behind_sniper.jpg'/> {% else %} <img src='sniper.jpg'/> {% endsometimes %} -- or -- {% sometimes .001 %} You win! {% else %} Sorry, not a winner. Play again! {% endsometimes %} -- or -- {% sometimes .5 %} This shows up half the time. {% endsometimes %}
This is a conditional templatetag decorator that makes it *very* easy to write template tags that can be used as conditions. This can help avoid template boilerplate code (e.g. setting a variable in your template to be used in a condition). All you have to do is define a function with expected parameters that returns True or False. Examples are in the code.
My admin allows editing of some html fields using TinyMCE, so I end up with horrible code that contains lots of nested `<p>`, `<div>`, `<span>` tags, and style properties which destroy my layout and consistence. This tag based on lxml tries to kill as much unneeded tags as possible, and style properties. These properties can be customized by adapting the regex to your needs.
This class generates a crows-foot notation ERD for your models (currently does not include fields) using GraphViz. The cardinality/modality of the relationships isn't perfect, but it works for 99% of cases out there.
A mixin to define permissions on models. This is more of an abstract model to subclass/customise than a plug-in solution. Explanations are [here](http://www.muhuk.com/2009/05/django-permission-system/).
This snippet is for [django-flag](http://code.google.com/p/django-flag/) Pinax app to make it generic moderator for any content model. You don't need to modify neither your model nor your views to moderate your flagged content objects.
Slightly shonky implementation of a custom URL shortening view, as [described on my blog](http://simonwillison.net/2009/Apr/11/revcanonical/). Depends on [baseconv.py](http://www.djangosnippets.org/snippets/1431/)
This TemplateTag simply returns a True when it is Naked CSS Day allowing you to hide your CSS or display a custom message on that date. Allows allows for parameters should the date change (again).
This is an example how to dynamically import modules other than `models.py` from installed apps. It allows you to define the full module path just once in `INSTALLED_APPS` in the settings. Using this technique makes it possible to write extensible and reusable apps as mentioned in [Abstract Models and Dynamicly Assigned Foreign Keys](http://djangotricks.blogspot.com/2009/02/abstract-models-and-dynamicly-assigned.html). Probably, it would be great to have some helpers for doing this in django itself. For example: from django.db import models from django.utils import importlib def import_installed(path): """ Imports a module from an installed app >>> import_installed("myapp.forms") <module 'myproject.apps.myapp.forms'> """ app_name, module = path.split(".", 1) app = models.get_app(app_name) return importlib.import_module(app.__name__[:-6] + module) UPDATE: Reported as ticket [#10703](http://code.djangoproject.com/ticket/10703)
By enabling this backend: AUTHENTICATION_BACKENDS = ( 'path.to.my.backends.CaseInsensitiveModelBackend', ) Your users will now be able to log in with their username, no matter whether the letters are upper- or lower-case.
Since the admin URLs refactoring, you can easily link to the admin change view thanks to named URLs. I just discovered it, hope it helps!
This is a function wrapping the code from [example](http://docs.djangoproject.com/en/dev/topics/pagination/#using-paginator-in-a-view) from django docs. The required parameters are: `request` which is a `Request` object from a view, and `objects` - a list of objects to paginate. You may want to tune number of items per page by specifying `count` and the name of a GET parameter through `param_name` To use it in your view just wrap the paginated object into a function for example: def someview(request): articles = Article.objects.all() ... some other logics ... return render_to_response(template, {'articles': paginate(request, articles)}
Django does not have ability to write {% if "item" in list %}, so I had to write this tag. It can be used just like ifequal tag
Inspired by [http://www.djangosnippets.org/snippets/712/](YUI Loader as Django middleware) This loads in css and javascript files where you want them (usually in the head) - but allows you to put them anywhere in your code - i.e. in a TemplateTag. so your head code will look like this: ` <head> ... <!-- HEAD_init --> ... </head> ` then somewhere in your templates you can load in javascript or css files like so: ` <!-- HEAD_include myfile.js myotherfile.css --> ` It automatically checks if you've already included the files, and only puts them in once. It automatically figures out if its a javascript or css file by the file name - If you have an irregular filename (i.e. a google maps api script url) you can force it by using either of the following tags: ` <!-- HEAD_include_js [my javascript file] --> <!-- HEAD_include_css [my css file] --> ` Or you can write inline code to get rendered in the head: ` <!-- HEAD_render <script> someJavascriptCall(); </script> --> ` Todo: make it compress the js into one file...
I often use it so I hope it helps! Usage: urlpatterns = patterns('', url(r'^nav/$', redirect('/navigation/')), url(r'^search/(?P<category_name>\w+)/$', redirect('/documents/%(category_name)s/')), and so on... ) It keeps GET arguments too.
