Rails: uniq vs. distinct

Question

Can someone briefly explain to me the difference in use between the methods uniq and distinct?

I\'ve seen both used in similar context, but

Answer 1

Its not exactly answer your question, but what I know is:

If we consider ActiveRecord context then uniq is just an alias for distinct. And both work as removing duplicates on query result set(which you can say up to one level).

And at array context uniq is so powerful that it removes duplicates even if the elements are nested. for example

arr = [["first"], ["second"], ["first"]]

and if we do

arr.uniq

answer will be : [["first"], ["second"]]

So even if elements are blocks it will go in deep and removes duplicates.

Hope it helps you in some ways.
