Converts a passed decorator to one that can be applied to a class based view (ie. automatically decorates dispatch). This means no more overriding dispatch for every view / request method you want to apply decorators to. Works in Django 1.3 but I suspect it probably works in 1.2 as well.
Renders enclosing contents as it is. Useful to avoid tags conflict with certain javascript libraries (eg. jquery-tmpl.js, mustache.js) Example usage: `<script class="content-tmpl" type="text/x-jquery-tmpl">` `{% alien %}` `{{ tmpl(results) "#results .item-tmpl" }}` `{% endalien %}` `</script>`
This snippet is an improved version of the [ifusergroup](http://djangosnippets.org/snippets/1576/) tag that allows spaces in any of the group names. It also fixes a small bug where if a group didn't exist none of the subsequent groups would be checked.

Truncates a string after a certain number of chars. Question: > *Why don't you use the built-in filter slice?* I need the "three points" (...) only when it really truncates.
You can extend the class **ModifiedModel** to set new fields, replace existing or exclude any fields from a model class without patch or change the original code. **my_app/models.py** from django.db import models class CustomerType(models.Model): name = models.CharField(max_length=50) def __unicode__(self): return self.name class Customer(models.Model): name = models.CharField(max_length=50) type = models.ForeignKey('CustomerType') is_active = models.BooleanField(default=True, blank=True) employer = models.CharField(max_length=100) def __unicode__(self): return self.name **another_app/models.py** from django.db import models from django.contrib.auth.models import User from this_snippet import ModifiedModel class City(models.Model): name = models.CharField(max_length=50) def __unicode__(self): return self.name class HelperCustomerType(ModifiedModel): class Meta: model = 'my_app.CustomerType' description = models.TextField() class HelperCustomer(ModifiedModel): class Meta: model = 'my_app.Customer' exclude = ('employer',) type = models.CharField(max_length=50) # Replaced address = models.CharField(max_length=100) city = models.ForeignKey(City) def __unicode__(self): return '%s - %s'%(self.pk, self.name) class HelperUser(ModifiedModel): class Meta: model = User website = models.URLField(blank=True, verify_exists=False)
I basically mixed both BRCPFField and BRCNPJField to create a widget that validates either an CPF or an CNPJ. The doc strings are not localized. So you probably have to hardcode it yourself.
`GPXMapping` is a subclass of `LayerMapping` that imports GPX files into 3D GeoDjango models (requires Django 1.2 or SVN r11742 and higher). Here's an example of GeoDjango models for GPX points and tracks, respectively: from django.contrib.gis.db import models class GPXPoint(models.Model): timestamp = models.DateTimeField() point = models.PointField(dim=3) objects = models.GeoManager() def __unicode__(self): return unicode(self.timestamp) class GPXTrack(models.Model): track = models.MultiLineStringField(dim=3) objects = models.GeoManager() Assuming the above models, then `GPXMapping` may be used to load GPX tracks and waypoints (including elevation Z values): track_point_mapping = {'timestamp' : 'time', 'point' : 'POINT', } track_mapping = {'track' : 'MULTILINESTRING'} gpx_file = '/path/to/file.gpx' lm = GPXMapping(GPXPoint, gpx_file, track_point_mapping, layer='track_points') lm.save(verbose=True) lm = GPXMapping(GPXTrack, gpx_file, track_mapping, layer='tracks') lm.save(verbose=True)
Save method, useful for automate pdf files creation if you want to use the file in database.
A simple InlineModelAdmin class that enables you to edit models that are bound by the instance via a generic foreign key (`content_type`, `object_id` pair) Use like: class PlacementInlineOptions( generic.GenericTabularInline ): model = Placement extra = 2 ct_field_name = 'target_ct' id_field_name = 'target_id' Can be also found at #4667
Tag for simple embed video from youtube watch link. It can be modified to manage size of embedded video.
If, like me, you've had trouble installing the [Python Imaging Library](http://www.pythonware.com/products/pil/) or [FreeType](http://freetype.sourceforge.org), you may have also had trouble getting a captcha to work. Here's my quick and dirty workaround — be warned, this is _very_ low level security, and shouldn't be used on high-profile sites. Originally published at <http://gregbrown.co.nz/code/django-captcha-without-freetype-or-pil/> Credit to the author of [django-simple-captcha](http://code.google.com/p/django-simple-captcha/), from whom I borrowed most of this code. ### Usage from django import forms from ABOVE-FILE import CaptchaField class CaptchaTestForm(forms.Form): myfield = forms.TextField() security_check = CaptchaField()
Place this snippet at the bottom of your settings.py file, and if a local_settings.py file is present in the directory, all settings in that file will override those in settings.py
This manager is based on the economical method of randomization. It usable in related models. For support this behavior required to be defined as default manger.
