The date field in the newforms module includes American style mm/dd/yyyy , which anyone outside the US will recognise as being complete madness. This date field behaves sensibly.

IfValueTag
Don't repeat yourself: when you wish to have a block of html with a variable value, but only if the variable is set, you can do this: {% ifvalue company.contact.email as email %} <h3>Email address</h3> <a href='mailto:{{ email }}'>{{ email }}</a> {% endifvalue %} Instead of this: {% if company.contact.email %} <h3>Email address</h3> <a href='mailto:{{ company.contact.email }}'>{{ company.contact.email }}</a> {% endifvalue %} The tags ifvalue and ifnotvalue are provided by this snippet. If you don't specify `as somename`, then the variable's value will be assigned to the name "value".

PyIf Template Tag (Conditional Tag)
Cheers to limodou for getting me thinking about this. The only problem with his implementation is that it doesn't support Django's "." syntax for accessing array/dict elements. In the Django style of allowing simple syntax for designers while allowing for greater flexibility, and less template duplication for conditionals that were previously impossible to represent in templates, I modified Django's built-in If tag. This is an adaptation/enhancement to Django's built in IfNode {% if ... %} that combines if ifequal ifnotequal into one and then adds even more. This Supports 1. ==, != 2. not .... 3. v in (1,"y",z) 4. <=, <, >=, > 5. nesting (True and (False or (True or False))) How to use it: {% pyif i == 1 or (5 >= i and i != 7) and user.first_name in ('John', 'Jacob') %} 'Tis true. {% else %} 'Tis false. {% endif %} I hope you like it.

Honeypot Field
Simple anti-spam field which will cause the form to raise a `ValidationError` if the value in this field changes. Displays as a CSS hidden `<input type="text" />` field. If you specify a `class` in the `attrs` of the widget, the default `style="display:none;"` won't be rendered with the widget so that you can use a predefined CSS style to do your hiding instead. You can also cause the widget to be wrapped in an html comment to ensure it is not visible to the end user: class EmailForm(Form): email = EmailField() website = HoneypotField(widget=HoneypotWidget( attrs={'class':'fish'}, html_comment=True))

{% with %} template tag
Add a value to the context (inside of this block) for easy access. Provides a way to stay DRYer in your templates. **NOTE:** This tag is now in Django core, so if you have Django >0.96 (or SVN) then you do NOT need this.

Better render_to_response
I'm finding this much more efficient (from a coding perspective) than using the `render_to_response` shortcut. It looks complex, but it's simple to use: just look at the example in the docstring. Call this script `renderer.py` and chuck it in your project root.

WordWrap template tag
Basically a clone of the default "wrap" filter. I use it to generate plaintext e-mail that has to be broken at 75 characters. {% wordwrap 80 %} Some text here, including other template tags, includes, etc. {% endwordwrap %} I prefer this over the {% filter wordwrap:80 %} as my template (e-mail) writers keep screwing it up.

Digg Style URL String Parser
Does a digg url effect to a string, can be useful for using an item's title in the url, from this: .hi's., is (a) $ [test], will it "work"/ \ to this: his_is_a_test_will_it_work I understand this isn't a very well made script, I am not very good at string manipulation. But I would be happy if someone would recode it in a faster, more managable way. I recomend saving the rendering.

Subclassing a model.field for newforms
The newforms fields are more capable than the django models fields. In this snippet, we subclass models.IntegerField, and add min_value and max_value. e.g. age = MMIntegerField('How old are you?', min_value=13, max_value=120)

MediaWiki Markup
This is a copy paste job of mediawiki's syntax parser built in Python. You'll probably have to edit it to fit your needs MediaWiki-style markup parse(text) -- returns safe-html from wiki markup code based off of mediawiki

Django Registration with GMail account
This code works with Django-registration app found here: http://code.google.com/p/django-registration/ If you plan to use this django-registrtion code in your website to allow user registration but do not run your own email server,this snippet can be handy. It uses gmail server to send out email. You have to install libgmail module first. Add two lines to your `settings.py` GMAIL_USERNAME = '[email protected]' GMAIL_PASSWORD = 'your_password' Change models.py - create_inactive_user(...) as given above

Authenticate with Email Address
This code gives you the ability to authenticate a user by their email address instead of the username. I've also added the ability to authenticate via LDAP. Some code used from this [snippet](http://www.djangosnippets.org/snippets/74/)

Convert newlines into <p> and </p> tags
Based upon (i.e., mostly lifted from) the built-in "linebreaks" and "linebreaksbr" filters, this one works as they do: `{{ object.text|paragraphs }}`
