Often a page contains a link to itself, with an additional parameter for in the url. E.g. to sort the page in a different way, to export the data into another format, etc... This tag makes this easy, avoiding any hardcoded urls in your pages.
When using [django debug toolbar](https://github.com/django-debug-toolbar/django-debug-toolbar), I like to be able to turn debugging on and off without having to edit my settings file. This callback makes that possible. Add `?debug=on` to the URL to turn debugging on. It will remain on in the current session until you turn it off with `?debug=off`. Make sure your session middleware comes before your debug toolbar middleware.
Apply a decorator to every urlpattern and URLconf module returned by Django's include() method . This allows you use a decorator on any number of views without having to decorate each one individually. The use case here is wrapping all of the Django Admin with a superuser decorator. This is code that's better left alone where we can't actually go in and decorate the Admin views and urlpatterns manually. It's also almost guaranteed the Admin will include() other URL files. So the added bonus is all the INSTALLED_APPS that have their admin.py files registered by admin.autodiscover() will be decorated automatically as well. This snippet is greatly inspired by [@miracle2k](http://djangosnippets.org/users/miracle2k/)'s excellent [#532](http://djangosnippets.org/snippets/532/). In the comments there @timbroder offers a modification to decorate includes but I think this is cleaner, simpler code and not subject to changes in the Django base code driving _get_url_patterns().
Very straightforward way to display a thumbnail in the admin using [django-thumbnails-works](http://pypi.python.org/pypi/django-thumbnail-works) . django-thumbnails-works requires [cropresize](http://pypi.python.org/pypi/cropresize/#downloadsInstaller) (which requires and installs PIL). Add 'thumbnail_works'to INSTALLED_APPS in settings.py and here you go. Tested in django 1.3 alpha.
This code allows you to upload a mp3 to the Admin Frontend. The ID3 tags are automatically read out and filled in to the according fields. This should work for other filetypes as well. As long as they have an id3 tag.
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.
Here's the python code to produce an admin related widget with the edit and delete link also. * [RelatedFieldWidgetWrapper](http://djangosnippets.org/snippets/2562) * [related-widget-wrapper.html](http://djangosnippets.org/snippets/2563) * [related-widget-wrapper.js](http://djangosnippets.org/snippets/2564) * [RelatedWidgetWrapperAdmin](http://djangosnippets.org/snippets/2565)
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
