A version of http://djangosnippets.org/snippets/2388/ which assumes UTC-based dates. This is when you store dates in UTC (as you should), and want to display them in your site's local timezone, and you notice that Django's timesince/time template tags still do not support timezones.
Memcached Property Attributes ----------------------------- Setting the attribute will store the value in memcached; accessing the attribute will retrieve from memcached. Most useful as a way of simulating memcached "fields" on model instances. See the docstring for details.
This widget allows you to display preview images with adjustable width and length of the link: [example](http://img526.imageshack.us/img526/6588/screenshotat20111026215.png) AdvancedFileInput(preview=True, image_width=200) For other files, you can adjust the length of the link without preview: [example](http://img845.imageshack.us/img845/6588/screenshotat20111026215.png) AdvancedFileInput(preview=False, url_length=30) by default, parameters are: preview = True url_length = 30 image_width = 200
Django admin orders models by their primary key by default, which can be undesirable on very large tables. This shows how to disable any ordering on a model. Note that this behavior is fixed in 1.4 trunk.
Fields are validate Ukrainian phone numbers in popular formats.
Rename apache (or any) processes to be easily identified from ps output.
A small script that takes a manage.py dumpdata generated json file, and removes fields of the specified models. I needed this because i kept my initial data on a json file and after I removed a field on one of my models, the script wouldn't work anymore.
If your application server is behind a proxy, `request.META["REMOTE_ADDR"]` will likely return the proxy server's IP, not the client's IP. The proxy server will usually provide the client's IP in the `HTTP_X_FORWARDED_FOR` header. This util function checks both headers. I use it behind Amazon's Elastic Load Balancer (ELB).
When using [django debug toolbar](https://github.com/django-debug-toolbar/django-debug-toolbar), I like to be able to turn debugging on and off without having to edit my settings file. This callback makes that possible. Add `?debug=on` to the URL to turn debugging on. It will remain on in the current session until you turn it off with `?debug=off`. Make sure your session middleware comes before your debug toolbar middleware.
It was based in: http://djangosnippets.org/snippets/1586/ Instead of doing this: 'attribute_name = forms.CharField(widget=forms.TextInput(attrs={'class':'special'}))` You can do this in your template: {{ form|cssclass:"attribute_name:special_class"|cssclass:"other_attribute:special_class" }}
Actually the best way to handle this is to use built-in http://docs.haystacksearch.org/dev/searchqueryset_api.html#load-all I just missed it while checking documentation and wrote this crappy snippet!
A FilterSpec that can be used to filter by taggit tags in the admin. To use, simply import this module (for example in `models.py`), and add the name of your TaggableManager field in the list_filter attribute of your ModelAdmin class.
Change model field attributes from a abstract base classes model in a dry way.
**Your model:** class TicketItem(models.Model): hours = models.DecimalField(decimal_places=2, max_digits=6) day = models.DateField() order = models.ForeignKey(Order) tickets = models.ManyToManyField(Ticket) Now you want to auto save m2m fields in your forms.TicketItemCreateForm: 1. inherit from m2mForm-Class 2. define m2m_field(s) **Example:** class TicketItemCreateForm(m2mForm): m2m_field = 'tickets' class Meta: model = models.TicketItem
Renders enclosing contents as it is. Useful to avoid tags conflict with certain javascript libraries (eg. jquery-tmpl.js, mustache.js) Example usage: `<script class="content-tmpl" type="text/x-jquery-tmpl">` `{% alien %}` `{{ tmpl(results) "#results .item-tmpl" }}` `{% endalien %}` `</script>`
