Subject: Re: Find elment in array of hashes

Thanks,

I tried your code but I keep getting nil, but I know for sure that the
value "3" is in there.

    sql = "SELECT p.id, s.price FROM services s inner join products as p
ON s.product_id = p.id where s.shop_id = 1"
    r  = ActiveRecord::Base.connection.select_all(sql)
    @array = r.find {|k,v| k[:id] == "3"}


if I change it to
 @array = r.find {|k,v| v[:id] == "3"}
I get
undefined method `[]' for nil:NilClass
