Load Template from App

Updated a similar snippet by "King" to work with Django 1.6. This is especially useful for overriding the admin templates without having to symlink or copy them into your project. For example {% extends "admin:base.html" %} would extend the admin page base.html.

Admin action for a generic "CSV Export" (fix for unicode)

Based on [#2369](https://djangosnippets.org/snippets/2369/) Save the snippet as actions.py within your django app, and then add an action on any model you want in it's ModelAdmin definition. Example usage: from actions import export_as_csv_action class YourModelAdmin(admin.ModelAdmin): list_display = (...) list_filter = [...] actions = [export_as_csv_action("CSV Export", fields=[...])] - Unicode fix (requires unidecode)

regex search in admin forms

Despite warning coming from django developers, I'm still using admin classes to quickly get into reverse engineering databases. One feature is missing: searching into fields thanks to a regex. One dirty solution I found is to overwrite get_search_results. But most of the code comes from django itself. If anyone has a better idea ;) **Usage:** 1. works since get_search_results is part of ModelAdmin (1.5 if I remember well) 2. Inherit your Admin class from RegexModelAdmin 3. enclose by / the field you want to regex with: `search_fields = ['/field/', ]`

Django admin autoregister

Official GitHub page: https://github.com/Mimino666/django-admin-autoregister One call to autoregister_admin() automatically creates and registers admin views for all the models in the specified module with intelligent linking between ForeignKey, OneToOneField and ManyToManyField fields.

Email backend to BCC all emails

The backend lets you quickly get an idea of all emails that are sent out. Helpful for debugging or keeping an archive of all communications. Use instead of Django's SMTPBackend.

Ultimate(?) export/download CSV admin action

This owes a debt to a number of earlier snippets by myself and others, including: *(most directly)* [#2868](http://djangosnippets.org/snippets/2868/), plus [#2020](http://djangosnippets.org/snippets/2020/), [#2712](http://djangosnippets.org/snippets/2712/), [#1697](http://djangosnippets.org/snippets/1697/) Use of OrderedDict means it requires Python 2.7+. You also need to `pip install singledispatch` which is a backport of a Python 3.4 feature. Singledispatch (along with custom attributes instead of a factory function) gives a very clean interface in your ModelAdmin, whether or not you need a custom `short_description`. This version allows you to (optionally) specify custom column labels, or to (optionally) use Django's usual prettifying mechanism (`field.verbose_name`). Thanks to #2868 it can do relation-spanning double-underscore lookups and also model attribute/method (rather than field) lookups for columns, just like you can in your ModelAdmin `list_display`.

Test runner that installs 'tests' packages as apps

Ever tried to unit test custom fields or abstract models? If so, you probably used a solution like [this one](http://djangosnippets.org/snippets/2843/). It surely works, but it has some issues: 1. Runs 'syncdb' several times. 2. It's not automatic. You must add the mixin or copy the code to each of the TestCases. This test runner adds to INSTALLED_APPS the 'app.tests' package for **each of the specified** apps, **before the 'syncdb' happens**. This has the [discovery runner](https://pypi.python.org/pypi/django-discover-runner) as a dependency (for 1.5 only, it will be the default in 1.6). However, it comes as a mixin so it should be easily pluggable to other test runners. If you intend to use the mixin with other runners, note that it imports 'app.tests.models' so it won't work with tests modules (tests.py). Your runner must "use" test packages (like discovery runner). # USAGE # in your settings.py: TESTAPPS_INSTALL = ( 'app1', 'app2', # ... ) TEST_RUNNER = 'testapp_runner.DiscoverTestAppRunner' # example import path # extra apps in command line. # run test for apps 'app1' to 'app4', adding 'app3' and 'app4' to the TESTAPPS_INSTALL setting. manage.py test app1 app2 app3 app4 --with-test-app=app3 --with-test-app=app4

Get derived model instance

Get derived model without storing their names or content types in databases. You write only one line, it expands into only one SQL-query (with many LEFT OUTER JOIN's). Model definition example: class BaseModel(models.Model): foo = models.IntegerField(null=True) derived = DerivedManager() class FirstChild(BaseModel): bar = models.IntegerField(null=True) class SecondChild(BaseModel): baz = models.IntegerField(null=True) How to use: >>> f = FirstChild.objects.create() >>> s = SecondChild.objects.create() >>> print list(BaseModel.objects.all() [<BaseModel object 1>, <BaseModel object 2>] >>> print list(BaseModel.derived.all() [<FirstChild object 1>, <SecondChild object 2>] >>> print BaseModel.derived.get(pk=s.pk) <SecondChild object 2>
