Twitter Bootstrap mixin for Django forms

http://twitter.github.com/bootstrap

Installation

Add 'bootstrap.forms' to INSTALLED_APPS

Usage

Define the form:

	from bootstrap.forms import BootstrapFormMixin,Field,Inline,Addon,TEMPLATE_PREFIX
	from django import forms

	class ExampleForm(BootstrapFormMixin,forms.Form):
	    class Meta:
	        bootstrap = (
	            Field('flight',span=3),
	            Inline('Flying',('from', Field('ex',span=2),'to',Field('to',span=2))),
	            Addon(field=Field('price',span=1),addon='$',prepend=False),
	            Addon(field=Field('gst',span=1),addon=Field('add_gst')),
	        )

	    flight = forms.CharField(help_text='E.g. CA147')
	    ex = forms.CharField(help_text='E.g. Shanghai')
	    to = forms.IntegerField(help_text='E.g. Sydney')
	    price = forms.IntegerField(help_text='AUD',label='GST')
	    gst = forms.IntegerField(help_text='%',label='GST')
	    add_gst = forms.BooleanField()
	    secret_field = forms.CharField(widget=forms.HiddenInput,required=True)

And mention it in the template:

	<div class="row">
	    <div class="span14">
	    	<form>
	    		<fieldset>
	    			<legend>Normal form</legend>
	    			{{form}}
	    		</fieldset>
	    		<fieldset>
	    			<legend>Form with errors</legend>
	    			{{error_form}}
	    		</fieldset>
			</form>
		</div>
	</div>

Or use template tags on a normal form:

	<fieldset>
		<legend>Form with errors rendered with templatetags</legend>
		{% bootstrap_field error_form.first_name error_form.last_name label='custom label' %}
		{% bootstrap_field error_form.gst append=error_form.add_gst span=5 %}
	</fieldset>
