Forms splitted in fieldsets
This template tag build a Form splitted in fieldsets. The fieldsets are configured with a second parameter, that is a tuple like the one used in the Admin class in models in the attribute "fields". You pass to the template the form and the tuple and than use them as parameters for the templatetag. You can take a look at the source and modify It to build forms the way you like. It is very useful If you do not like the way Django build forms with the methods as_p, as_ul or as_table and also do not like to write html by hand.

URL based breadcrumbs
This is a simple URL based breadcrumb filter I'm using on a site I'm currently building. To use it, just throw the code into template-tag file, and simply pass the current url in a page template like so {{ request.get_full_path|breadcrumbs }} As an example of how to style it, wrap it in a unordered list with an id of breadcrumb, and then in your styles use #breadcrumb li { display: inline; }. On a contact form for a site user, this will produce something along the lines of you are here : [home](/) » [users](/users/) » [username](/username/) » contact form Hopefully someone may find it useful.

Specify a manager for the Admin
This example shows how you can easily limit the objects in the admin by specifying which Manager the admin should use. I haven't seen this documented anywhere (perhaps I've missed it), but it's proven extremely useful to me. The example here will limit objects to those that are attached to the current Site, but you can use any Manager you want (for example, a Manager that shows only published Articles). Finally -- not that I'm suggesting this -- but you *could* combine this with the ThreadLocals trick to show only objects that have been created by that user.

Another Memcache Status View
This was inspired by [this memcache status snippet](http://www.djangosnippets.org/snippets/54/) However, this version uses the quasi-internal cache._cache.get_status(), and it compiles a list of stats for each server that you specify in your CACHE_BACKEND setting.

Cache Manager
I had a problem: too many fetches from the DB. So, how to reduce load on the database without major changes to the code? Cache Manager is the answer. I've managed to reduce number of DB hits as much as 80% in some cases (dictionaries, complex relations). It is using standard cache mechanisms. I'm using it with mathopd. This is a very simple solution, instead of standard Manager, put this in your model definition as: `objects = CacheManager()` Then everythere elase in the code instead of all() or get(...) call all_cached() or get_cached(). I've kept original methods intact, to have an dual access, when you really, really must have frest data from the DB, and you can't wait for cache to expire. This is much easier to work with, then manually getting fetched data from the cache.No change to your existing code 9except model) and voila! Additionally if you have some data, you would like to store with your serialized object (e.g. related data, dynamic dictionaries), you can do this in the model method '_init_instance_cache'). Drop me an email if you find this useful. :)

UPDATED: Django Image Thumbnail Filter
A Django image thumbnail filter, adapted from code by [Batiste Bieler](http://batiste.dosimple.ch/blog/2007-05-13-1/). This updated version drops support for cropping and just rescales. You should use it in your templates like this: `<img src='{{ MEDIA_URL }}{{ image.get_image_filename|thumbnail:"300w,listingimages" }}' alt="{{ image.title }}" title="{{ image.title }}" />` This will produce a 300-pixel wide thumbnail of image, with the height scaled appropriately to keep the same image aspect ratio. 'listingimages' is the path under your MEDIA_ROOT that the image lives in - it'll be whatever upload_to is set to in your ImageField. If instead you wanted an image scaled to a maximum height of 140px, you'd use something like this: `<img src='{{ MEDIA_URL }}{{ image.get_image_filename|thumbnail:"140h,listingimages" }}' alt="{{ image.title }}" title="{{ image.title }}" />` Note the number has changed from 300 to 140, and the trailing letter from 'w' to 'h'. Please leave feedback and bug reports on [my blog, Stereoplex](http://www.stereoplex.com/two-voices/a-django-image-thumbnail-filter). I've only lightly tested this so you'll probably find something!

Enhanced "avoid widows" template filters
Building on [jcroft's snippet](http://www.djangosnippets.org/snippets/17/), here's a slightly more advanced version which has two filters, one for basic text and the other for html snippets. Usage is like so: <h2>{{ blog_entry.headline|escape|widont }}</h2> {{ blog_entry.html|widont_html }} On top of Jeff's reasons for using these filters, they are important because they help keep one of [God's commandments](http://www.ebible.com/bible/NIV/Exodus+22%3A22). ;)

instant 'master' admin site
The newforms-admin branch (to be merged by 0.97, I think) is very nice to work with, separating models from the admin. It is trivial to create an admin site that includes every app that is installed. Note that you also get all your docs for things like template tags, etc.

keeptags: strip all HTML tags from output except a specified list of elements
Django has several filters designed to sanitize HTML output, but they're either too broad (striptags, escape) or too narrow (removetags) to use when you want to allow a specified set of HTML tags in your output. Thus keeptags was born. Some of the code is essentially ripped from the Django removetags function. It's not perfect--for example, it doesn't touch attributes inside elements at all--but otherwise it works well.

Fuzzy Time of Day
This filter will display the time as word(s) indicating roughly the time of day ("Morning", "Afternoon", "Evening", etc). For example, the following template snippet: Posted in the {{ post.date|fuzzy_time }} of {{ post.date|date:"F j, Y"} }}. will result in the following (assuming `post.date == datetime.datetime(2007, 6, 13, 20, 57, 55, 765000)`): Posted in the evening of June 13, 2007. The terms used and breakpoints (hours only) can be rather arbitrary so you may want to adjust them to your liking. See the docs for [bisect][] for help in understanding the code. Just remember you should have one less breakpoint than periods and the first breakpoint falls at the end of the first period. The idea was inspired by [Dunstan Orchard][1], although the code is *very* different (php case statement). He uses quite a bit more periods in a day, so you might want to take a look.
