Auto rendering decorator with options

This view decorator renders automaticaly the template with the context provided both by the view "return" statement. For example: @auto_render def my_view(request): ... return 'base.html', locals() You can still return HttpResponse and HttpResponseRedirect objects without any problems. If you use Ajax requests, this decorator is even more useful. Imagine this layout: def aggregating_view(request): ... context = locals() partial1 = partial_view_1(request, only_context=True) partial2 = partial_view_2(request, only_context=True) # aggregate template include partial templates return 'aggregate.htmt', context.update(partial1).update(partial2) def partial_view_1(request): ... return 'partial_1.html', locals() def partial_view_2(request): ... return 'partial_2.html', locals() This way you can render you view individualy for specific ajax calls and also get their context for the aggregating view.

Age - custom filter

Based on the discussion at Empty Thoughts (http://blog.michaeltrier.com/2007/8/6/age-in-years-calculation) I built a quick and dirty custom filter. Save this as a file in your "templatetags" folder. I called mine "calculate_age.py" and then in your template "{% load calculate_age %}" then use it, "{{ object.birthdate|age }}"

htmlentities

The built-in escape filter only works with certain characters. It works great in environments where you can declare your charset (UTF-8). However, not everything can handle anything outside of the ASCII charset. This replaces all non-ASCII characters with their encoded value as `®` for ®, for example.

SQLLoggerMidleware + infobar

This middleware will add a log of the SQL queries executed at the top of every page, in the form of an IE-like 'infobar'. It also includes a query count and total and per-query execution times. This snippet is based on snippet #344 "SQL Log Middleware + duplicates" by guettli. I did some adjustments to the code, to also add support for the application/xhtml+xml mime type, aswell as add the code for the infobar. Need DEBUG on, aswell as DEBUG_SQL, should not be used on production sites. It also expects a 16x16 png image called infobar_icon.png, which it is looking for in the /media/images folder (or /static/images, depending on your MEDIA_URL setting). I used a little light bulb icon from the Tango icon set, but am unable to attach the image. Any 16x16 png will do off course. Update 0.1.1: In the initial version of this middleware, the path to /media/images was hard-coded, and you had to adjust this middleware accordingly. Now, it correctly uses the MEDIA_URL setting from your settings.py file, so you no longer have to edit this middleware. 0.1.2: Made some adjustments to the CSS to get rid of a padding bug when the bar was displayed on a Django error page. Also if a page contains no queries, it won't bother printing an 'empty' table, with just column headers. 0.1.3: More tweaks to the CSS, odd/even row shading on queries table. 0.1.4: More CSS tweaks again 0.1.5: Minor tweaks 0.1.6: Sorry, I just realised that after some time, this snippet broke in the latest SVN of Django with a Unicode error, as arthur78 mentioned. I have managed to fix it, by wrapping line 258 and 259 in an str() function.

Simple Plone Migration

This is a very simple script to do a **simple** migration from plone content to django. ATNewsItems and PloneArticles are imported into the django model *Article* (with Foreignkey to the django models *File* and *Image*). ATDocuments are imported into the django model *Page*. **Usage** 1. Make sure that the Python version running Zope can import django 2. The django database should be writeable from within the Zope environment 3. Set the shell variable *DJANGO_MODULE_SETTING* to the settings file of the django project you want to import your Plone content to 4. Start the Zope server in the debug modus: $ bin/zopectl debug Then import the python module above, and pass the site you want to migrate to the start function: import simple_migration mysite = app.mysite simple_migration.start(mysite) Found 1253 objects Saved Test Document Type: ATNewsItem ... Hope it helps someone. Used for the migration of **Plone-2.5.3** content in a **Python-2.4.4** environment.

Template tags/filter for working with query strings

Some template tags/filter for working with query strings in templates. Examples: {% load qstring %} {% qstring %} # Prints current request's query string {% qstring as current_qstring %} # Same but goes to context {{ current_qstring|qstring_del:"key1" }} # Deletes all key1 values {{ current_qstring|qstring_del:"key1&key2" }} # Deletes all key1 and key2values {{ current_qstring|qstring_set:"key1=1&key2=2" }} # Deletes all old key1 and key2 values and adds the new values.

Currency filter

Formats a number in the local currency format. E.g., if `foo` is equal to `49277`, then > ` {{ foo|currency }}` would print > `$49,277` If your locale is the U.S. You can use this filter in your templates as described in the [Django documentation](http://www.djangoproject.com/documentation/templates_python/)

Time ranges like 7-9 p.m.

Template filter to format a start and end time in to a range. Uses Django's ["P" format](http://www.djangoproject.com/documentation/templates/#now) and assumes start and end time are on the same day or night before/morning after. `{{ start_time|time_range:end_time }}` Examples: 7-8 p.m. 8 p.m. - midnight noon - 4 p.m. 9:45 a.m. - 5:15 p.m. 10:30 p.m. - 1:30 a.m.

Alternate method of autoloading Django models in ipython

This is a little improvement to the [idea](http://www.djangosnippets.org/snippets/540/) from sheats a few days ago. I like it over the previous solutions because it doesn't involve doing anything other than running `./manage.py shell` inside your project directory. You don't have to create any files anywhere or remember to call anything, and `ipython` still works fine outside of a Django project. Throw this code in `~/.ipython/ipy_user_conf.py` (`ipythonrc` has apparently been deprecated).

Add the attribute "rel='lightbox'" to all Links, if the target is an image. `<a href="/path/to/image.jpg">Image</a>` becomes `<a rel="lightbox" href="/path/to/image.jpg">Image</a>` Works for JPG, GIF and PNG Files.

really spaceless (trim spaces at line start)

This tag is meant to override the current implementation of '{% spaceless %}' tag and remove spaces at the beginning of a line too. I.e. a template like this: <div> <div>useless space up front</div> </div> will become this `<div>` `<div>useless space up front</div>` `</div>` All the other behaviour of spaceless stays the same! Put this in your app/name/templatetags/tags.py And if you want it to override the default "spaceless"-tag to the following from django.template import add_to_builtins add_to_builtins('app.name.templatetags.tags')

"for" template tag with support for "else" if array is empty

This is a customized version of the default `for` template tag which takes an optional `{% else %}` clause that will be displayed if the given array is empty. from django.template import * >>> t1 = Template(""" {% load mytags %} {% for athlete in athlete_list %} {{ athlete }} {% else %} No athlete in list! {% endfor %} """) >>> c1 = Context( {'athlete_list': ['me', 'myself', 'I'] }) >>> t1.render(c1) u'me myself I ' >>> c2 = Context({}) >>> t1.render(c2) u'No athlete in list!' If you want to automatically override the builtin `for` template-tag add it to the builtins: from django.template import add_to_builtins add_to_builtins('python.path.to.mytags')

Capture template output as a variable

Tags like `url` and `trans` provide no way to get the result as a context variable. But how would you get a computed URL into a `blocktrans`? This snippet solves the general problem. Just put the template code whose output you want to capture within `captureas` tags. For example: {% captureas login_url %}{% url login %}{% endcaptureas %} {% blocktrans %} <a href="{{login_url}}">login</a> {%endblocktrans%}

Pad integers with leading zeros (template filter)

Disclaimer: I'm not the world's greatest programmer, so there may be better ways to do this, but it works for me (feel free to offer your improvements, though!). Basically, this will pad an integer with leading zeros and return a string representation. User it like this: {% forloop.counter|leading_zeros:"5" %} ...where "5" is the number of desired digits. In this case, if it was the 12th time through the forloop, the filter would return "00012". Why do this? Either for alignment, such as in tables, or for aesthetics -- for an example, see [Shaun Inman's comment section](http://shauninman.com/archive/2007/11/16/mobilesafari_view_source).
