How to iterate an array of hashes and return the interested array

Rails
1

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 json syntax nor is it valid ruby syntax. Are you
trying to parse a file with that
syntax?

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.

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

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’
^ ^
| |
array |
|
hash

Or,

outer_hash.values.each do |array|
array.each do |hash|
#do something with hash
end
end
