notify admin what fields have changed in form submission
here is some working code from a site that maintains profile information (address, phone number, etc) for users ("Partners"). this snippet handles the submitted form (after validation) and checks to see if any fields have been changed by the partner. if so, it shoots off an email to the admin showing the current profile information with changed fields marked with asterisks.

Thumbnails in admin using django-thumbnails-works
Very straightforward way to display a thumbnail in the admin using [django-thumbnails-works](http://pypi.python.org/pypi/django-thumbnail-works) . django-thumbnails-works requires [cropresize](http://pypi.python.org/pypi/cropresize/#downloadsInstaller) (which requires and installs PIL). Add 'thumbnail_works'to INSTALLED_APPS in settings.py and here you go. Tested in django 1.3 alpha.

TLS(SSL) middleware, per URL pattern or whole site
Allows url patterns to include a boolean indicating whether a view requires TLS(SSL). The accompanying middleware handles the redirects needed to make sure that it upholds this requirement. **WARNING**: this monkey-patches some Django internals and is difficult to test since Django's TestClient does not support TLS. If you use this make sure you test it thouroughly. Add this to your Django settings USE_TLS = True # The default for this setting is False. URL pattern usage url(r'^login$', 'myproject.login.index', {'require_tls': True}, name='login-index'), Use `require_tls` True to force the middleware to perform redirects needed to make sure your are serving this view using https. Use `require_tls` False to force the middleware to redirect to http. Be careful with this setting, this may not behave as you expect. If you don't care if the view is served via https or http then do not include `require_tls` in the pattern. If you wish to have every view in the site served with TLS then specify the following Django setting ALWAYS_USE_TLS = True # Django setting, use TLS for every view

joinstrings filter
In one situation I needed to join strings in template, so I wrote this filter. Use it like this: 1) var = 23 {{"I have eat %d apples today."|joinstrings:var}} -> "I have eat 23 apples today." var = '23' {{"I have eat %s apples today."|joinstrings:var}} -> "I have eat 23 apples today." 2) var = [23, 45] #or any iterable object (except string - see pt. 1) {{"I have eat %d apples and %d pears today."|joinstrings:var}} -> "I have eat 23 apples and 45 pears today."

Image inlining template tag lib
A custom templatetag for inlining image in the browser. The principe is to base64 encode the image and avoid a http request. There is a cache handling, you just have to specify a writable directory. An example of the utilisation (template part): [http://djangosnippets.org/snippets/2267/](http://djangosnippets.org/snippets/2267/) The explication on [http://raphaelbeck.wordpress.com/2010/11/14/make-inline-images-to-improve-performance-with-django-template-tags/](http://raphaelbeck.wordpress.com/2010/11/14/make-inline-images-to-improve-performance-with-django-template-tags/)

Improved Accept middleware with webkit workaround
An accept middleware, which is based on the code of http://djangosnippets.org/snippets/1042/ but adds a workaround for the buggy accept header, sent from webkit browsers such as safari and chrome. The workaround affects any accept header, that has xml and (x)html in the best q, but also the xml mediatype at first place in the list. If this is the case, the header is rearanged, by shifting the xml mediatype to become the last element of the best quality entries in the header. If the workaround did manipulate the header, and there is a html entry in the list with lower quality as an xhtml entry that is also in the list (with best q), then the html entry is also raised in q to be one entry in front of xml.

Limit ForeignKey filter values to those that have a relationship with current model
This is an updated snippet based on http://djangosnippets.org/snippets/2260/ The updated snippet can limit the filtering options for a foreign key field to only those entries that are related to the current model. I.e. if you have an Author model with a FK to Institution model, you can configure Author's changelist to include a filter on Institution, but only allow you to select institutions that have authors. Institutions that do not have authors won't show up on the list. To enable this, in your model's ModelAdmin class, set <fieldname>_fk_filter_related_only=True <fieldname>_fk_filter_name_field=<display this field of the related model in filter list> For example, in your AuthorAdmin class, you can do institution_fk_filter_related_only=True institution_fk_filter_name_field='name' Note that for the effect described above to work, you just need the last few lines of the big else clause in __init__, so if you don't care about filtering by FK property, you can just grab those few lines and create a simpler FilterSpec.

Monkey-patch Django's test client to return WSGIRequest objects
Testing low-level functionality sometimes requires a WSGIRequest object. An example of this is testing template tags. This will monkey-patch the test Client object to return WSGIRequest objects Normal Django behavior: >>> client.get('/') <HttpResponse > With this code, get the request object: >>> client.request_from.get('/') <WSGIRequest > Installation: For this to work, you simply need to import the contents of this file. If you name this file `clientrequestpatch.py`, do this inside your Django tests. from django.test.testcases import TestCase from myproject.test import clientrequestpatch
- request
- test
- client
