CSVImport
This is an awesome script! The original can be found here: http://www.djangosnippets.org/snippets/633/ I had to make a couple minor changes to get it working for me, so I thought I would share the love...

ByteSplitterField
When you want to save integers to the db, you usually have the choice between 16-, 32- and 64-bit Integers (also 8- and 24-bit for MySQL). If that doesn't fit your needs and you want to use your db-memory more efficient, this field might be handy to you. Imagine you have 3 numbers, but need only 10 bit to encode each (i.e. from 0 to 1000). Instead of creating 3 smallint-fields (48 bit), you can create one 'ByteSplitterField' which implements 3 'subfields' and automatically encodes them inside a 32 bit integer. You don't have to take care how each 10-bit chunk is encoded into the 32-bit integer, it's all handled by the field (see also field's description). Additionally, the Field offers opportunity to use decimal_places for each of your subfields. These are 'binary decimal places', meaning the integer-content is automatically divided by 2, 4, 8, etc. when you fetch the value from the field. You can also specify how values are rounded ('round' parameter) and what happens when you try to save a value out of range ('overflow' parameter) Not implemented (maybe in the future if I should need it sometime): * signed values. All values are positive right now! * real (10-based) decimal places (actually you could probably directly use DecimalFields here) * further space optimization, i.e. saving into CharField that's length can be chosen byte-wise

Whitelisted overwriting FileSystemStorage

Generate QR Code image for a string
Generate QR Code image from a string with the Google charts API http://code.google.com/intl/fr-FR/apis/chart/types.html#qrcodes Exemple usage in a template {{ my_string|qrcode:"my alt" }} will return the image tag with * src: http://chart.apis.google.com/chart?chs=150x150&cht=qr&chl=my_string&choe=UTF-8 * alt: my alt"

Generic CSV Export
This will generically add csv exporting to your views in the admin. It will default to exporting the entire table you see (without paging). If the table only has one column, it will export the fields the the model. You can overide this functionality. I ended up creating my own admin/change_list.html to apply this functionality universally: {% extends "admin/base_site.html" %} {% load adminmedia admin_list i18n %} {% block stylesheet %}{% admin_media_prefix %}css/changelists.css{% endblock %} {% block bodyclass %}change-list{% endblock %} {% if not is_popup %}{% block breadcrumbs %}<div class="breadcrumbs"><a href="../../">{% trans "Home" %}</a> › {{ cl.opts.verbose_name_plural|capfirst|escape }}</div>{% endblock %}{% endif %} {% block coltype %}flex{% endblock %} {% block content %} <div id="content-main"> {% block object-tools %} <ul class="object-tools"> <li><a href="csv/{%if request.GET%}?{{request.GET.urlencode}}{%endif%}" class="addlink">Export to CSV</a></li> {% if has_add_permission %} <li><a href="add/{% if is_popup %}?_popup=1{% endif %}" class="addlink">{% blocktrans with cl.opts.verbose_name|escape as name %}Add {{ name }}{% endblocktrans %}</a></li> {% endif %} </ul> {% endblock %} <div class="module{% if cl.has_filters %} filtered{% endif %}" id="changelist"> {% block search %}{% search_form cl %}{% endblock %} {% block date_hierarchy %}{% date_hierarchy cl %}{% endblock %} {% block filters %}{% filters cl %}{% endblock %} {% block result_list %}{% result_list cl %}{% endblock %} {% block pagination %}{% pagination cl %}{% endblock %} </div> </div> {% endblock %}

ultralize
This is a function based on django's urlize modified to show different media based on their url. It supports images, links, mp3/ogg links, youtube videos, vimeo videos and dailymotion videos. I added a switch called mini to have two modes to show things in different places. When mini is activated it will only parse the first url provided and discard the rest as well as limiting the height.

create_c
Instead of creating a dictionary on every view everytime you could do this and just call it like c = create_c(request)

Template tags for localizing UTC times with pytz
For example: Last modified: {% localdt item.modified_utc %} ({% localtimesince time.modified_utc %}) Converts the input datetimes to the timezone specified by the localtz context variable (it can also be explicitly specified, and all those other sensible things). Input UTC datetimes can be specified using either a datetime or a timestamp. Provides `localdt`, `localtime`, `localdate` and `localtimesince`.

Management command to list custom management commands
I work with multiple projects, many of which have multiple custom management commands defined. It can be hard to remember them, and slow to pick them out of the "manage.py help" list. This quickie command lists all of a project's custom commands (along with their help text). Writing it was easy after looking at the source of django.core.management. Open questions include: how do you decide which app to put this command in? Should this command list itself?

All Imports Checker
I was using flup to run django in fcgi mode and encountered the dreaded "Unhandled Exception" page quite frequently. So apart from all the precautions about handling this except, I wrote the above code snippet, which checks the import across your ENTIRE project. Ofcourse this can be used on any python project, but I have written it for my favorite framework django. It is now written as a Django command extension, an can be run as: **python manage.py imports_checker** This is a generic command, it does not check the settings.INSTALLED_APPS setting for cleaning. But can be improved to do the same. Public Clone Url: [git://gist.github.com/242451.git](git://gist.github.com/242451.git) Update: Now it supports checking imports, just only at the app level also usage: python manage.py imports_checker <appname>

"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')

Update applications
This snippet is based on 928. I've added the support to update a custom folder, using shell arguments. It requires the argparse module. You can install it with: pip install argparse Usage: # Updates repositories in the specified <folder path> # The default is the ./ folder update_repos --path <folder path> # List available options update_repos -h Alessandro Molari

ImageWithThumbsField
Easy way to generate image thumbnails for your models. Works with any Storage Backend. From: [http://code.google.com/p/django-thumbs/](http://code.google.com/p/django-thumbs/) **Usage example:** ============== photo = ImageWithThumbsField(upload_to='images', sizes=((125,125),(300,200),) To retrieve image URL, exactly the same way as with ImageField: my_object.photo.url To retrieve thumbnails URL's just add the size to it: my_object.photo.url_125x125 my_object.photo.url_300x200 Note: The 'sizes' attribute is not required. If you don't provide it, ImageWithThumbsField will act as a normal ImageField **How it works:** ============= For each size in the 'sizes' atribute of the field it generates a thumbnail with that size and stores it following this format: available_filename.[width]x[height].extension Where 'available_filename' is the available filename returned by the storage backend for saving the original file. Following the usage example above: For storing a file called "photo.jpg" it saves: photo.jpg (original file) photo.125x125.jpg (first thumbnail) photo.300x200.jpg (second thumbnail) With the default storage backend if photo.jpg already exists it will use these filenames: photo_.jpg photo_.125x125.jpg photo_.300x200.jpg **Note:** It assumes that if filename "any_filename.jpg" is available filenames with this format "any_filename.[widht]x[height].jpg" will be available, too.
