django-livevalidation is a Django app that provides quick and easy client-side form validation which validates as you type. It uses the Live Validation JS library in conjunction with Django Forms. This is by no means a replacement to Django's built in form validation, but it is a suppliment which is purely client-side baed which cuts down on server-side requests for validation. This version of django-livevalidation requires Django >= 1.2, for previous versions please use this project: http://opensource.washingtontimes.com/projects/django-livevalidation/
Install
Place 'livevalidaiton' into your INSTALLED_APPS and make sure it is above the Django admin since it overrides some of the admin templates:
INSTALLED_APPS = (
'livevalidation',
...
'django.contrib.admin',
)
Usage
To use livevalidation in your templates, make sure you load the headers first before doing anything:
{% include 'livevalidation/header.html' %}
This loads the JS library at js/livevalidation_standalone.compressed.js and the CSS at css/livevalidation.css. Feel free to tweak the CSS to your liking
Now you can use the templatetag to validate a form instance:
{% live_validate form [option=value ...] %}
Where the form is any django.forms.Form (or subclass) instance. The optional option=value kwargs are in pairs as follows:
* validMessage - message to be used upon successful validation (DEFAULT: "Thankyou!")
* onValid - javascript function name to execute when field passes validation
* onInvalid - javascript function name to execute when field fails validation
* insertAfterWhatNode - id of node to have the message inserted after (DEFAULT: the field that is being validated)
* onlyOnBlur - whether you want it to validate as you type or only on blur (DEFAULT: False)
* wait - the time you want it to pause from the last keystroke before it validates (milliseconds) (DEFAULT: 0)
* onlyOnSubmit - if it is part of a form, whether you want it to validate it only when the form is submitted (DEFAULT: False)
Requirements:
· Python
· Django
