Admin list thumbnail

This code will add a thumbnail image to your Model's Admin list view. The code will also generate the thumb images, so the first view may be a little slow loading. This assumes you have an **ImageField** in your Model called **image**, and the field's **upload_to** directory has a subdirectory called **tiny**. You then must add **"thumb"** to your Model's Admin **list_display**. The thumbnail images are also linked to the full size view of the image. I found this **VERY** useful... hope someone else does as well.

SQL Log Middleware - with multiple databases

This is an improvement of [joshua](http://djangosnippets.org/users/joshua/)'s [SQL Log Middleware](http://djangosnippets.org/snippets/61/). If you have more than one database connection, then all queries are logged, grouped by connection. If a connection has no queries, then it's not shown.

Profiling Middleware w/sorting

Based *very heavily* on the middleware in [this snippet](http://www.djangosnippets.org/snippets/727/). As with that one, append '?prof' to the URL to see profiling output instead of page output. The big change is that you can also pass an argument to control sorting. For example, you can append '?prof=cumulative' to sort the results by the cumulative time consumed. See the [documentation on the Stats class](http://docs.python.org/library/profile.html#pstats.Stats.sort_stats) for all the options.

Add the decorator to an already defined templatetag that returns a Node object: @with_as def do_current_time(parser, token): ... return a_node The decorator will patch the node's render method when the "as" syntax is specified and will update the context with the new variable. The following syntaxes are available: {% current_time %} {% current_time as time %} {{ time }}

It defaults to .2, %20. {% sometimes %} <img src='spy_behind_sniper.jpg'/> {% else %} <img src='sniper.jpg'/> {% endsometimes %} -- or -- {% sometimes .001 %} You win! {% else %} Sorry, not a winner.
