Working With Rails

It’s dead simple … Just take a look at the examples and you should be fine …
http://livevalidation.com/examples

ya checked that.. but which .js file to download.. can u just briefly explian… because i am very new to ror and interested in live validation….

There should be a file named livevalidation_standalone.compressed.js in your download files – copy it to your public/javascripts file and include it. That should do the trick.

Just a little recommendation: If you’re new to Rails, I’d suggest building your first apps without too much AJAX because it can sometimes be quite tricky. Try to get comfy with Rails first and add the AJAX stuff later.

HTH

thanx kof.. let me try it and know u the results…

Sergio Gil released a plugin recently which allows automatic integration with the livevalidation library. The nice thing is that it uses the validations defined in your model to generate the javascript which keeps things nice and DRY.
Not all validations are supported but the main types are all there.

You can find the docs here: http://livevalidation.rubyforge.org/

And always remember that any client-side validation is cosmetical only. As the saying goes – never trust user input. Use live validation all you want, but make sure all data is also checked again by implementing the proper validation in your model.
