Jquery ajax csrf framework for Django

1. Framework to extend the jquery ajax() function to construct post requests that contain a csrf token. 2. The example view used with the framework takes JSON data and returns JSON data containing either: 3. "success" with a message and additional dictionary of JSON data to use in the page 4. "error" with an error message. 5. The ajax function framework satisfies Django's csrf requirements by injecting a csrf token into the post requests created using the function. This example is a form with ~160 fields that we wanted to help fill in customer information to automatically. 1. User calls the lookup() script from the onblur attribute of the customer_id form field by leaving the field. 2. The lookup script takes the contents of the customer_id formfield and uses the jquery ajax() function to construct a JSON post request to the "/json /?act=" url. 3. The json view takes actions as get requests. We pass the post request to the JSON url already including the get request. "/json/?act=lookup" 4. The jquery framework in the snippet includes a csrf token in the ajax request automatically. 5. The customer_id is passed as JSON to the json view lookup action and customer details are attempted to be looked up in the database. 6. If successful the request returns a JSON dictionary of customer details which are pushed into the formfields using javascript in the lookup() function. The end result is if the user fills out the customer_id field of the form first (which we suggest with tooltip overlay) the customer name and address information will populate automatically. *Credit to Guangcong Luo https://github.com/Zarel

Something like list_detail generic view but returns PDF document instead

This should work as a `django.views.generic.list_detail` generic view but will produce PDF version of given template. This code is merged code from perenzo's [example](http://www.djangosnippets.org/snippets/659/) and code from `django.views.generic.list_detail` module. `pisa` package is required from (http://www.htmltopdf.org/download.html) with `html5lib` package and Reportlab Toolkit 2.1+ NOTE: this is code for Django 0.96. In Django 1.0 change in line 3: ObjectPaginator to Paginator

JSONField

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)**

SuperChoices

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()

Django model objects and querysets dehydration/hydration

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

Sphinx Search ORM / Revised

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.

Absolute URL Templatetag

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/

Header view decorators

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.
