Question

Let’s say we have a hash:

flash = {}
flash[:error] = "This is an error."
flash[:info] = "This is an information."

I would like to convert it to a string:

"<div class='error'>This is an error.</div><div class='info'>This is an information".

in nice one liner 😉

I found something like that:

flash.to_a.collect{|item| "<div class='#{item[0]}'>#{item[1]}</div>"}.join

That solves my problem but maybe there is nicer solution built in hashtable class?

Answer 1

Hash includes Enumerable, so you can use collect:

flash.collect { |k, v| "<div class='#{k}'>#{v}</div>" }.join
