how to convert a hash value returned from a date_select in rails to a Date object?

Question

I have a date_select in my view inside a form, however on submit the value returned is in a hash form like so:

{\"(1i)\"=>\"2010\", \"(2i)\"=>\"8\", \"         


        

Answer 1

I don't know about a rails way, but this "one-liner" does the trick:

irb(main):036:0> d = Date.parse( {"(1i)"=>"2010", "(2i)"=>"8", "(3i)"=>"16"}.to_a.sort.collect{|c| c[1]}.join("-") )
=> #
irb(main):037:0> d.to_s
=> "2010-08-16"

Or, with less magic:

h={"(1i)"=>"2010", "(2i)"=>"8", "(3i)"=>"16"}
d=Date.new(h['(1i)'].to_i, h['(2i)'].to_i, h['(3i)'].to_i)
d.to_s
=> "2010-08-16"
