How to set a minimal Ruby page on a webserver that can add / edit / delete records?

I am trying to add a page on dreamhost.com to display

record = Record.find(params[:id])   # such as Record.find(1)
print record.content                # to show content of this record

and that's it... probably using sqlite or mysql, and want to have the ability to add a record, similar to Ruby on Rails's scaffold.

If using Ruby on Rails, it is probably too big for such a sim开发者_运维知识库ple purpose, but if I use Sinatra, then it looks like I have to start it on a port (and can't start it on port 80 because it is the dreamhost.com's port)

Can Sinatra or any tool or framework fit this purpose?

Go with Rails

Dreamhost offers Rails already installed and at no extra cost. And knowing Rails will certainly be more useful to you in the future than knowing Sinatra.

So, I don't see the benefit in Sinatra unless you are hosting the server.

Since Rails is a framework, it will give you a basic application easily, despite it's massive internal complexity.

I know this doesn't exactly answer the question, sorry about that, but on a shared-hosting site you will have limited opportunity to fiddle with the configuration. It's easier in this case to go with Rails.

Rails isn't really that heavyweight. Unless you need your "app" to be very high performance, Rails is probably a good solution that'll let you have this up in a matter of a couple hours.

That said, I'm sure Dreamhost has a way for you to run a Sinatra app within Phusion.

I wonder why nobody mentioned Padrino yet. It is lightweight and provides you with a simple admin interface!
