Included Snippets

186. Profiling Middleware

Displays hotshot profiling for any view. Add a "prof" key to the query string by appending ?prof (or &prof=) and you'll see the profiling results in your browser, i.e. http://yoursite.com/yourview/?prof

Original Snippet - http://djangosnippets.org/snippets/186/

To enable add snippetscream.ProfileMiddleware to your MIDDLEWARE_CLASSES setting, i.e.:

MIDDLEWARE_CLASSES = MIDDLEWARE_CLASSES + ('snippetscream.ProfileMiddleware',)

963. RequestFactory

Easily create mock request objects for use in testing.

Original Snippet - http://djangosnippets.org/snippets/963/

Example:

from snippetscream import RequestFactory
request = RequestFactory().get('/')

1031. Model Inheritance With Content Type

Supplies a model class aware of its child models, allowing for child class objects to be resolved from parent objects.

Original Snippet - http://djangosnippets.org/snippets/1031/

Example:

=== example usage in interpreter ===
>>> from snippetscream import PolyModel
>>> class TrunkModel(PolyModel):
...     pass
>>> class LeafModel(TrunkModel):
...     pass
>>> leaf_obj = LeafModel()
>>> leaf_obj.save()
>>> trunk_obj = TrunkModel.objects.get(id=leaf_obj.id)
>>> trunk_obj
... <TrunkModel: TrunkModel object>
>>> trunk_obj.as_leaf_class()
... <LeafModel: LeafModel object>

1378. Resolve URLs to View Name

Supplies a resolve_to_name function that takes in a path and resolves it to a view name or view function name (given that the path is actually defined in your urlconf).

Original Snippet - http://djangosnippets.org/snippets/1378/

Example:

=== urlconf ====
urlpatterns = patterns(''
    url(r'^some/url/$', 'app.views.view'),
    url(r'^some/other/url/$', 'app.views.other.view', name='this_is_a_named_view'),
)

=== example usage in interpreter ===
>>> from snippetscream import resolve_to_name
>>> print resolve_to_name('/some/url/')
'app.views.view'
>>> print resolve_to_name('/some/other/url/')
'this_is_a_named_view'

1875. Auto-create Django Admin User During syncdb

This avoids the frustrating step of having to set up a new admin user every time you re-initialize your database.

Original Snippet - http://djangosnippets.org/snippets/1875/

To enable add snippetscream to your INSTALLED_APPS settings and create the following setting:

CREATE_DEFAULT_SUPERUSER = True

2240. CSV Serializer

Supplies 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.

Original Snippet - http://djangosnippets.org/snippets/2240/

To enable add snippetscream.csv_serializer to your SERIALIZATION_MODULES setting, i.e.:

SERIALIZATION_MODULES = {
    'csv': 'snippetscream.csv_serializer',
}

Example:

=== example dumpdata usage ===
$ python manage.py dumpdata --format csv auth.user > users.csv

=== example usage in interpreter ===
>>> from django.core import serializers
>>> csvdata = serializers.serialize('csv', Foo.objects.all())

2536. Configurable defaults for contrib.sites default Site during syncdb

Modelled after #1875, this provides a more sensible default for the Site object created during the first pass of syncdb (default domain of localhost:8000). It means that the admin's view on site button will work automagically, amongst other things.

Original Snippet - http://djangosnippets.org/snippets/2536/

To enable add snippetscream to your INSTALLED_APPS settings and create the following setting:

CREATE_DEFAULT_SITE = True

If you'd like to customise the default Site yourself, you can specify DEFAULT_SITE_DOMAIN and DEFAULT_SITE_NAME settings, e.g:

DEFAULT_SITE_DOMAIN = 'my.site.com'
DEFAULT_SITE_NAME = 'My Site'

Optionally you can manually call the create_default_site method and pass name and domain arguments which take precedence over the settings parameters.
