Ways to examine models/objects in Ruby on Rails?

I'm currently looking through a system trying to figure out how things work together - I know a couple basic ways to examine objects (I'm in the console), such as Object.methods, but I was wondering if there were ways to find, say, it's attributes, and it's relationships with other models (for example, has_many relationships) and the like.

The Pry gem is awesome for this sort of thing.

Dig this Railscasts episode.

Sounds like you're referring to specifically an ActiveRecord object. If you look up the documentation on ActiveRecord (e.g., http://api.rubyonrails.org/classes/ActiveRecord/Base.html), you'll find a lot of methods to get some useful info. For example, to see the attributes, you could examine MyActiveRecord.attribute_names.
