Rails - Sep 2011 - How to iterate an array of hashes and return the interested array

Hi folks,

I have the following structure /json like:

{

    -
    items: [
        -
        {
            google_analytics_id: null
            title: "abc"
            type: "station"
            masthead_file: null
            slug: "abcd"
        }
        -
        {
            google_analytics_id: null
            title: "xyz"
            type: "station"
            masthead_file: null
            slug: "xyzt"
        }
etc.

I want to iterate the array of hashes and return for example the
second hash or return the value from the second hash for title key.
Can you provide some guidelines ?

Thank you,

Dan

That isn''t valid ruby syntax.  Are you trying to parse a file with that
syntax?

Take a look at this, http://developer.yahoo.com/ruby/ruby-json.html

my_array.select{|item| item[:key] == my_criterion}

..will give you an array of items that meet your needs if the
''item''
is a hash.

I already parsed the json call. The idea is that i want to access a
certain hash within :item => [] or return the slug value for title =>
"xyz"

Well, it looks to me like you have an outer hash with key/values, and a 
value is an array of hashes, so you would do this:


main_hash["items"][1]["title"] ==>
''xyz''


main_hash["items"][1]["title"] ==>
''xyz''
             ^     ^
             |     |
           array   |
                   |
                  hash
