given a hash of keys => values, I want to construct a conditional statement that the hash describes, in the form "a = b AND c = d", etc. So far I've came up with
| code: |
irb(main):001:0> foo = {"a"=>"b","c"=>"d"} => {"a"=>"b", "c"=>"d"} irb(main):002:0> bar = "" => "" irb(main):003:0> foo.each{|key, value| irb(main):004:1* bar = "#{bar} #{key} = #{value} AND" } => {"a"=>"b", "c"=>"d"} irb(main):005:0> bar.slice!(0..-4) => " a = b AND c = d " |
which seems like a pretty ugly solution. I especially don't like that last hack on a leftover "AND". Is there a more eligant approach?
While #collect gives me a nice array
| code: |
irb(main):007:0> foo.collect => [["a", "b"], ["c", "d"]] |
the #join acts as if the array was flattened
| code: |
irb(main):006:0> foo.collect.join("*") => "a*b*c*d" |
