I have been looking but so many of them are just snippets, or out of date (different file locations etc, assets vs public etc etc).

Also, how up to date is the tutorial list on this site?  I would read through them but it does not appear to have been updated since 2007.

All I am trying to do is have a link button submit with POST data, then update a div with content from a different controllers action.

The tutorials I have read so far either are full of bugs, are out of date, or skip many steps, particularly in choosing what kind of JavaScript approach to use, JQuery, CookieScript, I just cannot find something which explains setting it up, then performing what used to be ridiculously simple tasks in Rails 1.

For the simple things I am trying to do it seems needlessly convoluted, I get the idea of code separation blah blah blah but I am one step away from just writing old fashioned JS myself.

A rails3 tutorial that guides one through the creation of a model for time calculations.

The format is time_in and time_out with the ability to do a calculation to give one the total hours as an integer. For example:
08:00am to 04:15pm giving one the total hours of 08.25 hours.

The view should show these fields horizontally aligned across the page. And of course, as if I am not asking enough already, as you enter these fields they use unobtrusive javascript and update the view adding row after row in the form with and edit button and a locked button next to each entry.

Ok...I know that I am asking a lot but I willl gladly pay if someone is willing to create such a tutorial.
Thanks for your time and generosity.

2. How to install plugins with Rails

This may sound confusing, but is it possible in Rails to build a very basic app whose on job is to redirect what people type in for that site to something on another site? Here's an example:

Let's just say that a netflix.com URL to a movie is something like netflix.com/search?category=Fantasy&name=Heroes&blahtechnical-stuff

Could you make a really simple app in Rails at say the domain netflixit.com that allows people to just type in like netflixit.com/fantasy/heroes and be instantly directed to the netflix version? So, I guess it has to convert and change the URL, but I don't know how. The website would be pretty much blank. The only thing it would be used for is automatically redirecting to the netflix site. The idea is just to give people an easier way to find something in a database type site if they already know what they are looking for.

It may be really simple, if so, could anyone point me in the right direction as for already made tutorials or something?

Thanks!

EDIT: Another feature it could have would be a counter for every URL it redirects.

Star ratings
Autocomplete movie titles
Making the site overall more secure
Optimizing the site's performance
...whatever else would go with something like this.

Thanks

Actually I am interested in learning ruby as a web programming language. Please suggest me some easy to learn tutorials specifically for ruby web programming.

Many thanks
