manage.py reboot

1) Simply create a "management/commands" folder in one of your INSTALLED_APPS folders. Then add a "reboot.py" file in your "management/commands" 2) In settings.py, you can OPTIONALLY add: PROJECT_NAME = 'Blah' PROJECT_DOMAIN = 'blah.com' These two settings will be used to create a "Site" object as well as a superuser. If you choose not to use these settings, the reboot command simply reverts to using your DATABASES[default] username as superuser. 3) Execute the command via "python manage.py reboot" Enjoy.

Validation for full e-mails (e.g. "Joe Hacker <[email protected]>")

Out of the box, Django e-mail fields for both database models and forms only accept plain e-mail addresses. For example, `[email protected]` is accepted. On the other hand, full e-mail addresses which include a human-readable name, for example the following address fails validation in Django: Joe Hacker <[email protected]> This package adds support for validating full e-mail addresses. **Database model example** from django import models from full_email.models import FullEmailField class MyModel(models.Model): email = FullEmailField() **Forms example** from django import forms from full_email.formfields import FullEmailField class MyForm(forms.Form): email = FullEmailField(label='E-mail address') I maintain this code in a [GitHub gist](https://gist.github.com/1505228). It includes some unit tests as well.

Fetching list of SQL queries executed so far for all requests

These snippets together give you the ability to view all Django SQL queries executed across all incoming requests by visiting a particular URL (`/profiling` in the example). This is useful when developing with the Django test server. This is useful if most of the incoming requests are AJAX requests, because in such cases the debug toolbar will not be able to show which queries got executed. The `SqlProfilingMiddleware` class is the key one. At the end of every incoming request it appends the executed SQL queries to a static class member list. Any information request profiling information can be added in this way. The snippet does not add any security around viewing such information. This was done just to keep the code simple. But when implementing this you will definitely want to restrict access to this URL to only people allowed to view such information.

Admin actions as buttons instead of a menu [v2]

Add this to your admin change_list.html template to replace the actions drop-down with buttons. This is a rewritten version of snippet [1931](http://djangosnippets.org/snippets/1931/) with Django 1.3 compatibility and cleaner code. Thanks to [andybak](http://djangosnippets.org/users/andybak/) for the idea.

Generic object_detail view with multiple named URL filters

This snippet is greatly inspired by [@jlorich](http://djangosnippets.org/users/jlorich/)'s useful [#2436](http://djangosnippets.org/snippets/2436/). The main difference is that I wanted to choose the names of my URL params instead of being forced into naming them "value1", "value2", etc. When reversing the URL you have to remember that the kwargs aren't friendly. By using the same names in the `filters` list, you don't have to change the way your otherwise write the URL pattern. Also it's clear throughout how you'll be filtering the QuerySet. The other change I made was "erroring early". This avoids running the QuerySet all over again inside `object_detail()` just to have it raise an exception we could have caught the first time.

ModelChoiceField with option groups

This is a ModelChoiceField where the choices are rendered in optiongroups (this is already posible with a normal Choicefield) For this to work properly the queryset you supply should already be ordered the way you want (i.e. by the group_by_field first, then any sub-ordering)

create or update, then get, model instances from JSON/py dict

Basically the idea is to import/update model instances from a json data that closely matches the model structure (i.e. identical field names) From my answer to this question: [http://stackoverflow.com/a/8377382/202168](http://stackoverflow.com/a/8377382/202168) See the original question for sample data format.
