if you have multiple choice field in front and you need just a string contains chosen values this is it! Unicode encoding row related with another snippet - "Switched value typed choice field", In typical cases, you do not need to call additional methods.
Decrease the verbosity of writing view tests. Also available here: https://gist.github.com/1310549.
Sometimes I don't want to reveal a staff-only view so I created this decorator, using ``django.contrib.admin.views.decorators.staff_member_required`` as my boilerplate. Non staff members are kicked to the 404 curb. Suggestion: Create a file, ``decorators.py`` in your project (or single app) and import like so: ``from myproject.app_name.decorators import staff_or_404``.
Just a quick and dirty solution I needed to uniquely color code entries in a selection form list. It uses the hashlib to generate it's coloring.
Unfortunately the built in Django JSON serialzer encodes GeoDjango GeometyrField as WKT text. This snippet extends django's serializer and adds support for GEOJson format. Built in JSON serializer output: [{"pk": 1, ... "geopoint": "POINT (-76.5060419999999937 44.2337040000000030)" ... }] GeoJSON serializer ouput: [{"pk": 1, ... "geopoint": {"type": "Point", "coordinates": [-76.503296000000006, 44.230956999999997], "__GEOSGeometry__": [ "__init__", [ "SRID=4326;POINT (-75.5129950000000036 44.2442360000000008)" ] ] }] Note: the "__GEOSGeometry__" is a class hint as defined by JSON-RCP and used during deserilization.
This mimicks the keys used internally by the @cache_page decorators and site-wide CacheMiddleware. Now you can poke them, prod them, delete them, do what you like with them (eg, delete after you update some content and you want a specific URL refreshed).
Model backend that enables permissions for AnonymusUsers. I wanted it to be as simple as possible so anonymous users just forward their permission checks to some fixed user model. This instance can be edited via django admin, assigned to groups, etc. To control which user will represent anonymous user you use ANONYMOUS_USER_NAME setting in settings file. To provide some sensible level of security i enforce following for user that represents anonymous user: * This user must have password equal to UNUSABLE_PASSWORD * This user may not log in * You cant cange password for this user via admin. You need to enable this backend by setting AUTHENTICATION_BACKENDS. Please note that you should not place this backend alongside django ModelBackend. This backend inherits from it.
Use this paginator to make admin pages load more quickly for large tables when using PostgreSQL. It uses the reltuples statistic instead of counting the rows when there is no where clause. To use this code, add the following in your admin: `class BigTableAdmin(admin.ModelAdmin): paginator = LargeTablePaginator def get_changelist(self, request, **kwargs): return LargeTableChangeList `

Adds Boolean like Filter in Admin to OneToOneField reference. Allowing to filter in the Parent for instances without Referenced Field. To register the filter, import in `urls.py` for example: import filterspecs Example `models.py`: from django.db import models class Place(models.Model): name = model.CharField(maxlength=50) address = model.CharField(maxlength=80) class Restaurant(meta.Model): place = model.OneToOneField(Place) place.exists_filter = True serves_hot_dogs = model.BooleanField() serves_pizza = model.BooleanField() Example `admin.py`: from django.contrib import admin from models import * class PlaceAdmin(admin.ModelAdmin): list_filter = ('restaurant',) admin.site.register(Place, PlaceAdmin) With this example PlaceAdmin will have a filter: By Restaurant All Yes No Where `Yes` will list `Place` with `Restaurant` instances, and `No` will list `Place` without `Restaurant` instances.
Trying to build a state-machine that stores state in the model or in settings.py rather then in the database, I wrote this small generic pre_save hook that lets me leave all the data in the Model.
This widget renders choices as submit buttons. This may be a better choice than radio buttons + submit sometimes
When developing a site, I sometimes want to be able to visually reference the HTML before it's given a real context, and a view. This extra bit of code will allow you to add a directory within your templates dir, and pull any html files and subdirectories from it. I added the if statement to automatically use an index.html file if there's no file and extension at the end. You can substitute anything you like for the "html" in "(?P<base>html)". That's just passed as an argument to prepend to the template as a base directory for the templates.
Saves image from a url into django's ImageField in a model. Uses [requests](http://pypi.python.org/pypi/requests/) library.
