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?
Hash
includes Enumerable
, so you can use collect
:
flash.collect { |k, v| "<div class='#{k}'>#{v}</div>" }.join
