Question

I have a hash, @data looking similar to the following:

{
   "calcData"   =>   {
      "coverStartDate"      =>"10/08/2011",
      ...
      "part"=>      [
         {
            "licenceYears"            =>"10",
            "licenceType"            =>"1",

            ...

            "@partname"            =>"ratingData"
         },
         {                
            "dob"            =>"26/01/1964",
            "age"            =>"47",

            ...

            "@partname"            =>"driver"
         },

         ...
      ]
   }
}

There are various more sections in the part bit with difference @partnames.

What is the best way to select one of these @partname bits:

e.g.:

@data["calcData"]["part <<< where @partname="ratingData" >>> "]["licenceYears"]

How can I represent this logic in ruby/rails?

Answer 1

query = 'driver'

@data["calcData"]['part'].select{|part| part['@partname'].eql?query}
 => [{"dob"=>"26/01/1964", "age"=>"47", "@partname"=>"driver"}]
