Improved for BootStrap details: http://twitter.github.com/bootstrap/ Using: class AnyForm(forms.Form, CustomForm): pass Template: <form> {{ form.render_errors }} {{ form.as_div }} </form>
This is a custom field that lets you easily store JSON data in one of your model fields. This is updated to work with Django 1.1. **Example: (models.py)** from django.db import models import JSONField class MyModel(models.Model): info = JSONField() ** Example: (shell)** >>> obj = MyModel.objects.all()[0] >>> type(obj.info) <type 'NoneType'> >>> obj.info = {"test": [1, 2, 3]} >>> obj.save() **[Code at GitHub](http://github.com/bradjasper/django-jsonfield/tree/master)**
Seeing [snippet 1178](http://www.djangosnippets.org/snippets/1178/) reminded me that I also had a go at writing a Choices class at some point. I'm content with the result, but I doubt xgettext will discover your translation strings, which will no doubt be inconvenient. Here it is anyway, in all its overly-complicated glory :-) The following demo was pulled from the function's docstring tests. >>> simple = Choices("one", "two", "three") >>> simple Choices(one=0, two=1, three=2) >>> tuple(simple) ((0, u'ein'), (1, u'zwei'), (2, u'drei')) >>> (0, _('one')) in simple True >>> simple.ONE 0 >>> hasattr(simple, 'FOUR') False Ordering just follows the order that positional arguments were given. Keyword arguments are ordered by their value at appear after positional arguments. >>> [ key for key, val in simple ] [0, 1, 2] >>> Choices(one=1, two=2, three=3) Choices(one=1, two=2, three=3) A Mix of keyword and non-keyword arguments >>> Choices("one", two=2, three=3) Choices(one=0, two=2, three=3) Automatically generated values (for "one" below) should not clash. >>> Choices("one", none=0, three=1, four=2) Choices(one=3, none=0, three=1, four=2) Here is an example of combined usage, using different object types. >>> combined = Choices(one=1, two="two", three=None, four=False) >>> len(combined) 4 >>> (1, _('one')) in combined True >>> ('two', _('two')) in combined True >>> (None, _('three')) in combined True >>> (False, _('four')) in combined True And here is an empty choices set. Not sure why you would want this.... >>> empty = Choices() >>> empty Choices()
Dehydrates objects that can be dictionaries, lists or tuples containing django model objects or django querysets. For each of those, it creates a smaller/dehydrated version of it for saving in cache or pickling. The reverse operation is also provided so dehydrated objects can also be re-hydrated. *Example:* >>> import pickle >>> users = list(User.objects.all()[:20]) >>> print users [<User: Indiana Jones>, <User: Bilbo Baggins>, ...] >>> pickled_users = pickle.dumps(users) >>> print len(pickled_users) 17546 >>> dehydrated_users = dehydrate(users) >>> pickled_dehydrated_users = pickle.dumps(dehydrated_users) >>> rehydrated_users = hydrate(pickle.loads(pickled_dehydrated_users)) >>> print rehydrated_users [<User: Indiana Jones>, <User: Bilbo Baggins>, ...] >>> print len(pickled_dehydrated_users) 1471
A revised version of [zeeg's Sphinx Search ORM](http://www.djangosnippets.org/snippets/231/), using my Sphinx client and adding support for Sphinx's excerpt generator. It's still missing support for search modes/order_by/filter/exclude, but it should be easy and I will add the relevant methods soon as I need them. Usage is the same as zeeg's class, except that you can pass a field name (or tuple for related objects) to its constructor, that will be used for excerpts: class MyModel(models.Model): search = SphinxSearch(excerpts_field='description') MyModel.search.query('query') MyModel.search.query('query').count() Returns an ordered list of the objects in your database.
Very simple middleware to implement "remember me" functionality. Updates the session once per day to keep user logged.
The {% url %} templatetag is awesome sometimes it is useful to get the full blown URL with the domain name - for instance for links in emails. The **{% absurl %}** templatetag mirrors the behaviour of {% url %} but inserts absolute URLs with the domain of the current Site object. Usage: {% absurl viewname %} >>> http://www.example.org/my/view/
This file includes two Django view decorators `header` and `headers` that provide an easy way to set response headers. Also, because I have to work with a lot of cross domain requests, I include few shortcuts for convenience to set the Access-Control-Allow-Origin header appropriately.
Theses two templatetags make easy to add an active class on a navigation link. The first one is based on a regexp an search if the request path match it. The second one simply use view names.
Use this directive to show google-map if you don't want to use 'raw' directive. default location is my favorite place. Of course you can change it :)
This is a YAML version of http://djangosnippets.org/snipptes/2397
Provide additional context_data in case the submitted form is valid. This can be a message to confirm that the changes are saved.
For use with S3 BotoStorage STATICFILES_STORAGE ="storages.backends.s3boto.S3BotoStorage" and AWS_PRELOAD_METADATA = True Custom management command that compares the MD5 sum and etag from S3 and if the two are the same skips file copy. This makes running collect static MUCH faster if you are using git as a source control system which updates timestamps.
This is my POC code for a progress bar backend (for delivering JSON to some AJAX frontend) in Django using Django-Celery (with RabbitMQ). It is quite concise, yet it took me a while to get there because Celery's Documentation is IMHO rather puristic. Web development is meant to be copy-paste! Here you go!
