Use this in your form if you want to accept input in microseconds. In a ModelForm you can override the field like this: def __init__(self, *arg, **kwargs): super(MyForm, self).__init__(*arg, **kwargs) self.fields['date'] = DateTimeWithUsecsField() *Update* May 26 2009 - Updated to address a couple issues with this approach. See http://code.djangoproject.com/ticket/9459
Looks up for a template based on the template-name plus the current users language code. Loads the template and renders it with the current context. Example:: {% langinclude "foo/some_include.html" %} Based on the users LANGUAGE_CODE, assumed we have 'de', it tries to render the template 'foo/some_include.html.de'. If that doesn't exists, it renders the template 'foo/some_include.html'. This is the default behavior of the include-Tag. Basically this is a shortcut for the following code, just with a fallback for the default template:: {% ifequal LANGUAGE_CODE "de" %} {% include "foo/some_include.html.de" %} {% else %} {% include "foo/some_include.html" %} {% endifequal %} --- Ein deutscher [Weblogeintrag mit Beschreibung](http://www.mahner.org/weblog/sprachabhangige-template-imports/)
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.
Post new saved objects to Twitter. **Example:** from django.db import models class MyModel(models.Model): text = models.CharField(max_length=255) link = models.CharField(max_length=255) def __unicode__(self): return u'%s' % self.text def get_absolute_url(self): return self.link # the following method is optional def get_twitter_message(self): return u'my-custom-twitter-message: %s - %s' % (self.text, self.link) models.signals.post_save.connect(post_to_twitter, sender=MyModel)
A management.py loading customized SQL feeding it raw to the database backend. Just put it as `management.py` in your app and put whatever SQL you want run after syncdb in `app/sql/custom.backend_driver.sql`. If the `backend_driver` is skipped the SQL will be loaded no matter database backend. Since it is run after syncdb it will also be run for test.

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/)
For disabling autocomplete and security purpose, this snippet defines a CharField with a randomness name for each request of the form. This is useful for turning off autocomplete for credit card input in all browsers, without breaking the xhtml validation. * [https://wiki.mozilla.org/The_autocomplete_attribute_and_web_documents_using_XHTML#Security](https://wiki.mozilla.org/The_autocomplete_attribute_and_web_documents_using_XHTML#Security) * [http://en.wikipedia.org/wiki/Cryptographic_nonce](http://en.wikipedia.org/wiki/Cryptographic_nonce)
I wanted a global way to filter profanity w/out having to modify every model, view, or form. While middleware takes overhead, this technique is intended mainly for sites w/few postbacks. Hopefully this snippet will lead to more/better techniques in the comments below. Usage (settings.py): MIDDLEWARE_CLASSES = ( 'PROJECT_NAME.FILE_NAME.ProfanityFilterMiddleware', )
This is a field that allows multiple markup types but also stores the pre-rendered result in the database which offers an advantage over calling one of the render methods each time. Example usage looks like: class BlogPost(models.Model): ... post = MarkupField() the various extra fields can then be accessed as follows: BlogPost.objects.get(pk=1).post # raw content BlogPost.objects.get(pk=1).post_markup_type # markup type (plain text, html, markdown, rest, textile) BlogPost.objects.get(pk=1).post_rendered # content of post rendered to html BlogPost.objects.get(pk=1).post_as_html # property that access post_rendered but marked safe for easy use in templates After writing my initial version of this I was pointed at the similar http://www.djangosnippets.org/snippets/1169/ I find mine a bit more useful as it includes ReST and includes a mark_safe call to allow showing the rendered HTML directly. I have however borrowed the nice idea of dynamically building MARKUP_TYPES from #1169. Also available via http://gist.github.com/67724.
I use this snippet to simplify my auth system with flash uploader SWFUpload. flash_login_required ensures that the user is authenticated and inject the context dictionnary into the specified template. To redirect a user, just set the variable `context['redirect']` with an url. Remember to include the cookie js in your template to get the sessionid variable POSTed to your view: `<script type="text/javascript" src="/static/js/swfupload/swfupload.cookies.js"></script>`
I've often found myself wanting to store passwords for other web services (e.g. maillist managers, IMAP accounts, IM accounts etc) for use by a web application, but have not wanted to hard-code them in `settings.py` or store them as plaintext in the database. This uses the [pycrypto][] library to encrypt each bit of information using the concatenation of a salt value and the SECRET_KEY value from your `settings.py`, hopefully leading to a bit more security and flexibility. [pycrypto]:http://www.dlitz.net/software/pycrypto/ You'll probably want to add some views to let people edit these things as I can't find a way to make the admin interface play nicely with it. **Example usage:** In [1]: p = Password( name='IMAP account', slug='imap', username='example', password='password', host='imap.gmail.com' ) In [2]: p.host Out[2]: 'imap.gmail.com' In [3]: p.e_host Out[3]: '6wdyMDKYy8c=$YXw6t/Q9wI[...]' In [4]: p.save()
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
A drop-in module to allow for full-text searchable models with very little effort. Tested with PostgreSQL 8.3, but should work on earlier versions with the tsearch2 module installed.
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
