title: how to read/understand ruby/rails documentation
body: <p>How can i read in documentation the methods that my object supports? For example, if i made a has_many association in rails, how to know which methods exists on that, what type is it? I know i can call each method but where is documented that? I could not find that in anywhere! I would like to see that in documentation, not always having to call methods method on the object... is there something like the javadoc where i see the methods that my object has and which he inherits?</p>
  
  <p>Sorry about the stupid question but i'm new in ruby/rails =/</p>
