A FilterSpec that can be used to filter by taggit tags in the admin. To use, simply import this module (for example in `models.py`), and add the name of your TaggableManager field in the list_filter attribute of your ModelAdmin class.
By default, you can only see the action log ("History") for particular model instances and a list of your own actions on the admin's index. This adds a fully-fledged admin view for the LogEntry model, where you can filter actions by user, content type, action type, browse by change date, and also search in the change message. Add the code to any of your apps' admin.py. The entries will be visible only to superusers and won't be editable.
HTML allows an option in a <select> to be disabled. In other words it will appear in the list of choices but won't be selectable. This is done by adding a 'disabled' attribute to the <option> tag, for example: `<option value="" disabled="disabled">Disabled option</option>` This code subclasses the regular Django Select widget, overriding the render_option method to allow disabling options. Example of usage: class FruitForm(forms.Form): choices = (('apples', 'Apples'), ('oranges', 'Oranges'), ('bananas', {'label': 'Bananas', 'disabled': True}), # Yes, we have no bananas ('grobblefruit', 'Grobblefruit')) fruit = forms.ChoiceField(choices=choices, widget=SelectWithDisabled())
By default every time you change and save an object in the admin, the change_list "jumps" to the first page, so filters you used to find the object (or the pagination-page) have to be applied again. If you have to go through a multi-object-list step-by-step this could become really annoying. The above snippet changes this behaviour by returning to the referring URL when saving. Included in this URL are variables for the filters/pagination. The snippet is part of your custom Model.admin in admin.py.
This 'smart_spaceless' template tag is a replacement for Django's built-in 'spaceless'. If settings.DEBUG = True, spaces will not be removed to make debugging your template code easier. When DEBUG = False, spaces will be removed. Happy coding!
This is an enhancement of snippet [#172](http://djangosnippets.org/snippets/172/). Here I use [BeautifulSoup](http://www.crummy.com/software/BeautifulSoup/) — far more easier to install through pip in a virtualenv, and possibly a bit more maintained — to format and properly indent the rendered HTML from templates. I also added a check to only tidy contents in a `DEBUG=True` environment, regarding high impact on performance while doing so in production. Last, it's compatible with Django 1.2.x.
Adds `--pretty` option to django `./manage.py dumpdata` command, which produces pretty utf8 strings instead of ugly unicode-escaped shit: $ ./manage.py dumpdata app.pricingplan --indent=1 [ { "pk": 1, "model": "app.pricingplan", "fields": { "name": "\u0411\u0430\u0437\u043e\u0432\u044b\u0439", } }, { "pk": 2, "model": "app.pricingplan", "fields": { "name": "\u0425\u0443\u044f\u0437\u043e\u0432\u044b\u0439", } } ]% ./manage.py dumpdata app.pricingplan --indent=1 --pretty [ { "pk": 1, "model": "app.pricingplan", "fields": { "name": "Базовый", } }, { "pk": 2, "model": "app.pricingplan", "fields": { "name": "Хуязовый", } } ]%
Create in your template dir html files named example.static.html and with this snippet you can get the static page with the url /example/. If you put static file in a sub-directory, the url will be /sub-directory/example/ **Example:** `static_urls = StaticUrls()` `urlpatterns = patterns('', *static_urls.discover())` `urlpatterns += patterns('',` `(r'^admin/doc/', include('django.contrib.admindocs.urls')),` `(r'^admin/', include(admin.site.urls)),` `)`
CSV serialization for models. Can be used via the dumpdata/loaddata management commands or programmatically using the django.core.serializers module. Supports multiple header lines and natural keys. Add the following to settings.py: SERIALIZATION_MODULES = { 'csv' : 'path.to.csv_serializer', } Examples of usage: $ python manage.py dumpdata --format csv auth.user > users.csv from django.core import serializers csvdata = serializers.serialize('csv', Foo.objects.all()) To run the regression tests distributed with the Django tarball: $ cd /path/to/Django-1.2.x/tests $ PYTHONPATH=/path/to/myproject ./runtests.py --settings=myproject.settings serializers_regress
This will allow you to attach HTML multipart emails (HTML/text) and use inline images. In my example, I'm attaching an image that's stored as an 'attachment' to an 'event.' The file name of the attachment is called "inline.jpg" and I'm referencing it in my HTML message. I'm also attaching a VCAL file (.ics) file that has some information about an associated event.
This simple template tag can be used to add famfamfam's silk icons easily to any element in your template.
Using Python mixins, you can chain methods on your queryset.
Almost copied from snipplet http://djangosnippets.org/snippets/752/, but I used Google Maps API v3
`formfield_for_manytomany` allows you to limit the choices/queryset for a ManyToManyField, but without direct access to the parent object. This snippet stores a reference to the parent object in `get_formset` and allows limiting of `ManyToManyField`s to objects related to the same parent object. See `ExampleInline` for example usage. If for some reason you have a `ManyToManyField` in a `TabularInline`, just change the `template` in the subclass.
I recently needed an easy way to add different input types to form fields based on the type of input. So, I created a widgets.py file and added varying input classes to meet my needs.
