Does anybody are conscious of rails website hosts which will provide a free arrange for non-profits to obtain ready to go. I am certain it might simply be liberated to a particular point (bandwidth, disk, etc.) but want to explore the choices.

Take a look at Heroku. They do not provide custom plans for No-Profits, however base plan's free.

If you're located in the US, dreamhost will give you free hosting for non-profits: http://wiki.dreamhost.com/index.php/Non-profit_Discount

and they've a great guide for establishing rails here: http://wiki.dreamhost.com/Getting_Began_with_Ruby_on_Rails

The Five Megabytes storage at Heroku may be the database, only. For actual hosting of assets (files, videos, ...), they recommend using S3 (see http://paperwork.heroku.com/constraints#large-static-assets).

You could upgrade the database itself advertising media are into limits. The very first compensated plan's 50 Megabytes for $15 / month, see http://heroku.com/prices

Also, despite the fact that Heroku doesn't provide a "non-profit-plan", I am confident they'd be prepared to barter some type of link/free database upgrade-exchange whenever you make contact with them directly.
