Sometimes when sending email you want to specify a Return-Path different from the "From:" address on the email. The Return-Path is used for bounced email and is required for [VERP](http://en.wikipedia.org/wiki/VERP). This class overrides SMTPConnection so that you can specify return_path.
A zen study.
A simple filter that generates a url from an object that has a get_absolute_url method. {{ object|quick_url }} a previous, simpler approach: [#511](http://www.djangosnippets.org/snippets/511/)
Usage: {% mailto email [linktext] %} `email' parameter is required; linktext is optional, defaulting to the email address.
This javascript has the functionality of the 'Edit Object' bookmarklet as [described by James Bennett](http://www.b-list.org/weblog/2007/nov/07/bookmarklets/) but instead of putting it within a bookmarklet it creates a div on the page with a link to the main admin screen, an edit the object link, and logout link. Just include the javascript on any page you want the links to show up on and make sure that the page is using the populate_xheaders function to provide the needed headers as [described here](http://www.b-list.org/weblog/2007/nov/07/bookmarklets/). The built in generic views provide the needed headers by default.
This class will automatically create a django choices tuple like this: STATUS_CHOICES = django_choices(Draft=1, Public=2, Closed=3) Additionally, it includes a method that converts the choices tuple to a dictionary. Like this: STATUS = STATUS_CHOICES.to_dict() Those types can come in handy when you need to use those magic values in your code. Best done within the model once so everyone can use it. Code based on: http://www.djangosnippets.org/snippets/455/. By the way, if you want to just have the method without having to convert to the newer syntax.. it's backward compatible. Just add django_choices in front of the first paren for your choices tuple.
nnoDB tables within MySQL have no ability to defer reference checking until after a transaction is complete. This prevents most dumpdata/loaddata cycles unless the dump order falls so that referenced models are dumped before models that depend on them. This code uses Ofer Faigon's topological sort to sort the models so that any models with a ForeignKey relationship are dumped after the models they reference. class Entry(models.Model): txt = .... class Comment(models.Model): entry = models.ForeignKey(Entry) This code will ensure that Entry always gets dumped before Comment. Fixtures are an important part of the django Unit Testing framework so I really needed to be able to test my more complicated models. Caveats 1. You use this snippet to dump the data and the built in manage.py loaddata to load the fixture output by this program. A similar solution could be applied to the XML processing on the loaddata side but this sufficed for my situations. 2. This code does not handle Circular or self-references. The loaddata for those needs to be much smarter.
Inherit your forms from model from this ModelForm and it will check all the database fields with unique=True in `is_valid()`. This is a hack around [#5736](http://code.djangoproject.com/ticket/5736). It is actually a part of a grand problem mentioned in [#4895](http://code.djangoproject.com/ticket/4895). You can use this hack until the issue is fully resolved.
This snippet demonstrates the use of the SpecialOps patch ( [link here](http://hackermojo.com/mt-static/archives/2008/02/django-special-ops.html) )to the django 0.96 admin. Once you have the patch, adding actions like these is simple. You can use the @admin_action decorator on model and manager methods to expose them inside the admin. For manager methods, the method should accept a list of IDs. For model methods, only self should be required.
By default extend tag don't cache parents template. This is extend tag with patch. Workaround for bug: http://code.djangoproject.com/ticket/6586
I love the Django templates and ORM, but I prefer to use CherryPy as my web server. So I want to be able to do the equivalent of "python manage.py sql" but without actually needing to have a Django application. So I stick all of my models in a file named "models.py" and then run this script and it prints out all of the CREATE TABLE statements for my database.
template tag to format two dates as a date range
This middleware replaces the behavior of the APPEND_SLASH setting in the CommonMiddleware. Please set `APPEND_SLASH = False` and `SMART_APPEND_SLASH = True` if you are going to use this middleware. In your URL patterns, omit the trailing slash for URLs you want accessible without the slash. Include the slash for those URLs you wish to be automatically redirected from an URL with the slash missing. If a URL pattern exists both with and without a slash, they are treated as two distinct URLs and no redirection is done. Example urlpatterns = patterns('some_site.some_app.views', (r'^test/no_append$','test_no_append'), (r'^test/append/$','test_append'), (r'^test/distinct_url$', 'view_one'), (r'^test/distinct_url/$', 'view_two'), ) Behavior of URLs against the above patterns with SMART_APPEND_SLASH enabled: http://some_site/test/no_append → test_no_append() http://some_site/test/no_append/ → 404 http://some_site/test/append → http://some_site/test/append/ http://some_site/test/append/ → test_append() http://some_site/test/distinct_url → view_one() http://some_site/test/distinct_url/ → view_two() This module is also available [in our SVN repository](http://trac.ambitone.com/ambidjangolib/browser/trunk/middleware/common.py).
Easy comma separated users field. I use it take custom permission for some users.
Just a simple regex function to convert a camel case string ("ClassName") to a lower case string with underscores ("class_name"). Came across a need for this when I was trying to add properties to a model at runtime using `object.__class__.__name__`. This is a modification of the function "get_verbose_name" found in django.db.models.options.
