Iterate and search a JSON array for the element in the array - ruby

Question

I have a JSON array that looks like this:
response = {
"items"=>[
{
"tags"=>[
"random"
],
"timestamp"=>12345,
"storage"=>{
"url"=>"https://example.com/example",
"key"=>"mykeys"
},
"envelope"=>{
},
"log-level"=>"info",
"id"=>"random_id_test_1",
"campaigns"=>[
],
"user-variables"=>{
},
"flags"=>{
"is-test-mode"=>false
},
"message"=>{
"headers"=>{
"to"=>"random#example.com",
"message-id"=>"foobar#example.com",
"from"=>"noreply#example.com",
"subject"=>"new subject"
},
"attachments"=>[
],
"recipients"=>[
"result#example.com"
],
"size"=>4444
},
"event"=>"stored"
},
{
"tags"=>[
"flowerPower"
],
"timestamp"=>567890,
"storage"=>{
"url"=>"https://yahoo.com",
"key"=>"some_really_cool_keys_go_here"
},
"envelope"=>{
},
"log-level"=>"info",
"id"=>"some_really_cool_ids_go_here",
"campaigns"=>[
],
"user-variables"=>{
},
"flags"=>{
"is-test-mode"=>false
},
"message"=>{
"headers"=>{
"to"=>"another_great#example.com",
"message-id"=>"email_id#example.com",
"from"=>"from#example.com",
"subject"=>"email_looks_good"
},
"attachments"=>[
],
"recipients"=>[
"example#example.com"
],
"size"=>2222
},
"event"=>"stored"
}]
}
I am trying to obtain the "storage" "url" based on the "to" email.
How do I iterate through this array where x is just the element in the array
response['items'][x]["message"]["headers"]["to"]
Once I find the specific email that I need, it will stop and return the value of x which is the element number.
I was going to use that value for x and call response['items'][x]['storage']['url']
which will return the string for the URL.
I thought about doing this but there's gotta be a better way:
x = 0
user_email = another_great#example.com
while user_email != response['items'][x]["message"]["headers"]["to"] do
x+=1
value = x
puts value
end

Answer 1

target =
response['items'].detect do |i|
i['message']['headers']['to'] == 'another_great#example.com'
end
then
target['storage']['url']

Answer 2

This is another option by creating Hash with key of to's email. And on basis of it fetch required information like this:
email_hash = Hash.new
response["items"].each do |i|
email_hash[i["message"]["headers"]["to"]] = i
end
Now if you want to fetch "storage" "url" then simply do:
user_email = "another_great#example.com"
puts email_hash[user_email]["storage"]["url"] if email_hash[user_email]
#=> "https://yahoo.com"

Answer 3

You can use it as #Satoru suggested. As a suggestion, if you use case involves complex queries on json data (more complex than this), then you can store your data in mongodb, and can elegantly query anything.
