Is there a combined Ruby / Rails online documentation?

Question

There are a number of resources online that host Rails and Ruby documentation in various forms and styles. A number of them are good, but none of them document the modules and classes with the methods available from the numerous extensions provided by ActiveSupport and others.

For example, with the Standard ruby Hash class, the core ruby version is Here.

But, ActiveSupport has a number of extensions to the Hash class, one of them (Hash#except) is documented Here

In order to find the full documentation for the Hash class and a list of all methods available, you'd have to know all the different places to look and know which modules are included in which classes.

Is there any online documentation resource that attempts to document each class in Ruby / Rails with all of the mixed in extensions on a single page?

Update

I've seen and used the following resources, but I'm looking for something that documents the modules and classes as the are within the runtime environment, i.e. all the methods listed in Hash.instance_methods documented in one place (Hash is just an example)

• http://www.gotapi.com/rubyrails
• http://railsapi.com/
• http://apidock.com/rails
• http://api.rubyonrails.org/
• several others that aren't around anymore (i.e. noobkit)

Answer 1

http://railsapi.com/

You pick the version of Rails and Ruby that you want (and some other popular gems), and it will build you a custom set of docs. You can either download the docs, or browse them online. Love this site.

The only downside (for me) is they don't keep docs for Ruby 1.8.6 (only 1.8.7), which is what I run for Heroku.

Answer 2

http://apidock.com/ is very good too. Not only you get access to the documentation, but also to valuable comments left by users.

Answer 3

No, there isn't such a resource is also a possible answer.

If you are pretty sure there is no such resource, please vote this up.
