For example: Last modified: {% localdt item.modified_utc %} ({% localtimesince time.modified_utc %}) Converts the input datetimes to the timezone specified by the localtz context variable (it can also be explicitly specified, and all those other sensible things). Input UTC datetimes can be specified using either a datetime or a timestamp. Provides `localdt`, `localtime`, `localdate` and `localtimesince`.
If you want to test for trivial error in your add and changelist admin views, use this snippet. Save the snippet in admintests.py and put it anywhere in your pythonpath. Put this code in your tests.py: from django.test import TestCase from admintest import adminviews_test class TestAdminViews(TestCase): def test_admin_views(self): adminviews_test(self)
Django lacks support of MySQL's "tinyint" 8-bit-integer datatype. This snippet gives you a TinyIntegerField and a PositiveTinyIntegerField. Falls back Django's SmallIntegerField if a different database-engine is used
This snippet allows you to return back to the filtered change_list after clicking "Save" on a change form. Other snippets I've found don't seem to take into account clicking on "Save and add another" or "Save and continue"
Django's built-in {% regroup %} template tag is great, but sometimes, you need to pass in the attribute you want to group on instead of declaring the attribute when you define the tag. {% dynamic_regroup %} is identical in function to {% regroup %}, except that it will attempt to resolve a context variable for the attribute you want to group by. {% dynamic regroup %} is also backward compatible, so you can also hand in the attribute literal and it will work as expected. See the end of the code for an example of usage.
**Description** A filestorage system that + is whitlisted, + changes the file name and targeting directory to put the file in - with respect to (runtime) instance information. + replaces files if they exists with the same name.

This allows you to order the models on the index page of the administration site in a custom way. This modification goes in the index method of django.contrib.admin.sites.AdminSite. I personally monkey patched it in where my models are loaded and registered with the admin site. Be careful that if you add new models you update the sorting dictionary, else you will get a key error. If no sorting is defined for an app, it will default to alphabetical order. Note that you'll probably want to also insert this into the app_index function as well. --- If you like my work, please check out my employer's site at 829llc.com - Dan
Adding this mixing to your existing class based views allows for outputting of queries into any registered serialzier format -- very handy for dynamic JS based GUI on the JSON format. This generic view mixing was created on our last project which required a fancy JS based user experience and yet also needed to be accessible through non JS enabled browsers.
Usually I start an authentication app with this model. Don't forget to set it up in the settings file AUTH_PROFILE_MODULE = 'authentication.UserProfile'
Apply the `login_required` decorator to all the handlers in a class-based view that delegate to `cls.dispatch`. Optional arguments: * redirect_field_name = `REDIRECT_FIELD_NAME` * login_url = `None` See the documentation for the [`login_required`](https://docs.djangoproject.com/en/dev/topics/auth/#the-login-required-decorator) method for more information about the keyword arguments. Usage: @LoginRequired class MyListView (ListView): ...
By using map_path([directory_name]) you can avoid hard coding paths for a specific OS in your settings.py
See the function docstring.
This is http://djangosnippets.org/snippets/1376/ rewritten as a new class-style Loader, and slightly improved. Allows you to reference templates like this: app_label:some/template/name.html This makes it possible to insert customizations at any point in a template hierarchy. For example, you could replace a block within the base admin template: {% extends "admin:admin/base.html" %} {% block breadcrumbs %}Custom Breadcrumbs-Style{% endblock %}
Loading templates by path app.template_name -> app/templates/template_name.html app.subdir.template_name -> app/templates/subdir/template_name.html Usage: append in settings.TEMPLATE_LOADERS and using render_to('app.index', context)
This is a model that implements (most of) the python dictionary interface. Meaning, you can work with this model exactly like a python dictionary, and it handles querying the database for it's values, saving/deleting the helper objects, etc. I wrote this originally when I needed to store an arbitrary dictionary in the database, and decided to work it up into a near-complete implementation of a dictionary. In order to make sure that the dictionary is the most optimized possible, I have a static method that can be used for retrieval. Feel free to ignore it if you don't care about optimizing database queries. Here's an example: Python 2.6.1 (r261:67515, Jun 24 2010, 21:47:49) [GCC 4.2.1 (Apple Inc. build 5646)] on darwin Type "help", "copyright", "credits" or "license" for more information. (InteractiveConsole) >>> from binder.models import Dictionary >>> d = Dictionary.getDict('Foobar') >>> print d {u'Foobar': u'omgbbq', u'HAHAHAH': u"who's afraid of a big, black, bat?"} >>> d['pot'] = 'The kettle is black.' >>> print d {u'Foobar': u'omgbbq', u'pot': u'The kettle is black.', u'HAHAHAH': u"who's afraid of a big, black, bat?"} >>> print d['pot'] The kettle is black. >>> for k, v in d.iteritems(): ... print k +":", v ... Foobar: omgbbq HAHAHAH: who's afraid of a big, black, bat? pot: The kettle is black. >>> print d.keys() [u'Foobar', u'HAHAHAH', u'pot'] >>> print d.values() [u'omgbbq', u"who's afraid of a big, black, bat?", u'The kettle is black.'] >>> There's several more functions that I've implemented; check the code to see. (An interesting note: DictField saves immediately upon making a change, which is good to keep in mind in case that functionality isn't expected.) Hope someone finds this useful. :) --Chris
