Parsing, Extracting & Returning JSON as Hash - json

Question

I am trying to make a localized version of this app: SMS Broadcast Ruby App
I have been able to get the JSON data from a local file & sanitize the number as well as open the JSON data. However I have been unable to extract the values and pair them as a scrubbed hash. Here's what I have so far.
def data_from_spreadsheet
file = open(spreadsheet_url).read
JSON.parse(file)
end
def contacts_from_spreadsheet
contacts = {}
data_from_spreadsheet.each do |entry|
puts entry['name']['number']
contacts[sanitize(number)] = name
end
contacts
end
Here's the JSON data sample I'm working with.
[
{
"name": "Michael",
"number": 9045555555
},
{
"name": "Natalie",
"number": 7865555555
}
]
Here's how I would like the JSON to be expressed after the contacts_from_spreadsheet method.
{
'19045555555' => 'Michael',
'19045555555' => 'Natalie'
}
Any help would be much appreciated.

Answer 1

You could create array of pairs (hashes) using map and then call reduce to get a single hash.
data = [{
"name": "Michael",
"number": 9045555555
},
{
"name": "Natalie",
"number": 7865555555
}]
data.map{|e| {e[:number] => e[:name]}}.reduce Hash.new, :merge
Result: {9045555555=>"Michael", 7865555555=>"Natalie"}

Answer 2

You don't seem to have number or name extracted in any way. I think first you'll need to update your code to get those details.
i.e. If entry is a JSON object (or rather was before parsing), you can do the following:
def contacts_from_spreadsheet
contacts = {}
data_from_spreadsheet.each do |entry|
contacts[sanitize(entry['number'])] = entry['name']
end
contacts
end

Answer 3

Not really keeping this function within JSON, but I have solved the problem. Here's what I used.
def data_from_spreadsheet
file = open(spreadsheet_url).read
YAML.load(file)
end
def contacts_from_spreadsheet
contacts = {}
data_from_spreadsheet.each do |entry|
name = entry['name']
number = entry['phone_number'].to_s
contacts[sanitize(number)] = name
end
contacts
end
This returned back clean array here:
{"[phone]"=>"Michael", "[phone]"=>"Natalie"}
Thanks everyone who added input!
