themed_template_loader
I developed this template loader for adding themes support in [gitology](http://www.amitu.com/gitology/). In order to support theming django applications, add this template loader at as the first TEMPLATE_LOADERS settings.py setting. Anywhere you request base.html, blog/index.html, when the theme is set to "bw", it will look for bw/base.html or bw/blog/index.html files first. Takes care of both render_to_response() in view or {% load template %} in templates.

Pagination shortcut
This is a function wrapping the code from [example](http://docs.djangoproject.com/en/dev/topics/pagination/#using-paginator-in-a-view) from django docs. The required parameters are: `request` which is a `Request` object from a view, and `objects` - a list of objects to paginate. You may want to tune number of items per page by specifying `count` and the name of a GET parameter through `param_name` To use it in your view just wrap the paginated object into a function for example: def someview(request): articles = Article.objects.all() ... some other logics ... return render_to_response(template, {'articles': paginate(request, articles)}

Readonly fields on Form/Modelform
A Form and ModelForm which provides the ability to specify certain fields as readonly, meaning that they will display their value as text wrapped with a <span> tag. The user is unable to edit them, and they are protected from POST data insertion attacks. The recommended usage is to place a NewMeta inner class on the form, with a readonly attribute which is a list or tuple of fields, similar to the fields and exclude attributes on the Meta inner class. class MyForm(ReadonlyForm): foo = forms.TextField() bar = forms.TextField() class NewMeta: readonly = ('foo',) Use these forms as you would a standard form in your templates.

Uk postcode googlemap templetag
Entirely based on and with big thanks to: [http://www.tomanthony.co.uk/](http://www.tomanthony.co.uk/) Drops in a googlemap with a placemarker based on a uk postcode Looks like this: {% googlemap_from_ukpostcode postcode "XxY" zoom %} e.g. {% googlemap_from_ukpostcode "SP27AS" "220x290" 16 %} postcode and zoom can optionally be template variables. "XxY" is the x/y size of the map you want to drop in. zoom can be omitted and defaults to 14. requires: in settings: GOOGLE_AJAX_API_KEY, GOOGLE_MAPS_API_KEY google_map_ukpostcodes.js: is slight variation on js at http://www.tomanthony.co.uk/demo/geocode_uk_postcode/gmap.js For further and better info see: [http://www.tomanthony.co.uk/blog/geocoding-uk-postcodes-with-google-map-api/](http://www.tomanthony.co.uk/blog/geocoding-uk-postcodes-with-google-map-api/)

inclusion tag with template as variable
Sometimes you need to write a tag that renders other template, but the template name depends on template tag arguments. Usually you use simple_tag or write your own Node class. Here is a simple aproach that uses inclusion_tag. This way you can use context objects when used with takes_context=True
- template
- tag
ifcontains tag
Django does not have ability to write {% if "item" in list %}, so I had to write this tag. It can be used just like ifequal tag
- tag
- if
- ifcontains
- block-tag
head inclusion middleware
Inspired by [http://www.djangosnippets.org/snippets/712/](YUI Loader as Django middleware) This loads in css and javascript files where you want them (usually in the head) - but allows you to put them anywhere in your code - i.e. in a TemplateTag. so your head code will look like this: ` <head> ... <!-- HEAD_init --> ... </head> ` then somewhere in your templates you can load in javascript or css files like so: ` <!-- HEAD_include myfile.js myotherfile.css --> ` It automatically checks if you've already included the files, and only puts them in once. It automatically figures out if its a javascript or css file by the file name - If you have an irregular filename (i.e. a google maps api script url) you can force it by using either of the following tags: ` <!-- HEAD_include_js [my javascript file] --> <!-- HEAD_include_css [my css file] --> ` Or you can write inline code to get rendered in the head: ` <!-- HEAD_render <script> someJavascriptCall(); </script> --> ` Todo: make it compress the js into one file...

general-purpose django XMLRC dispatcher
create an instance of this class: `rpcserver = XMLRPC()` then define handlers on it with the register decorator: @rpcserver.register("pingback.ping") def handle_pingback(sourceURI, targetURI) # ... de-serialization of the arguments and serialization of the return values is handled by the XMLRPC object, so just expect python built-in types as your arguments and use them as your return values. you can also raise instances of xmlrpclib.Fault from within your handlers and a proper xmlrpc fault will be sent out as the response. then you can use `rpcserver.view` in your urlconf to offer up your XML-RPC service at a URL: urlpatterns = patterns('', url(r'^$', rpcserver.view, name="xmlrpc"), # ... )

Unit Test Profiling
A test runner for Django unittests which profiles the tests run, and saves the result. Very useful for diagnosing your apps. Place the top portion of the code into a file called `profiling.py` someplace in your python path. Update your `settings.py` file with the bottom two lines of the code. Now you are ready, so just run `python manage.py test [appnames...]` to test any apps listed with profiling. By default this will just print a nice report after the unittests. If you change the value of `TEST_PROFILE` to a file, the profile will be saved to that file. The latter is recommended because these profiling reports have a lot of info in them, so it is best to tear through them with the `pstats` module.

More flexible "Partial Template"
This is an extension of the snippet http://www.djangosnippets.org/snippets/1302/ to make it a bit more flexible and been able pass more than one parameter to our "Partial Template". To use it you can {% partial_template template_name param1:variable1 param2:variable2 ... %} or: {% partial_template partials/mini_template.html item:data1 var2:"False" var3:"2*2" %}
