This view is asking for a p tag wrapped around the string
representation of the return value of func. As written, func returns
the input hash. Try something like this:
def func(hash)
hash.collect do |k, v|
"#{k} -> #{v}"
end.join("<br>")
end
It will return "animal -> true<br>number -> 5" for your sample input.
