Question

here is my problem, i get a variable from a request and store it in @response.

then i debug response, debug(@response), and get this output:

--- !ruby/hash:Hashie::Mash
results:
- !ruby/hash:Hashie::Mash
  id: '33098557'
  firstName: john
  lastName: star
  relationship: self
  photo: https://foursquare.com/img/blank_boy.png
  tips: !ruby/hash:Hashie::Mash
    count: 0
  lists: !ruby/hash:Hashie::Mash
    groups:
    - !ruby/hash:Hashie::Mash
      type: created
      count: 1
      items: []
  gender: male
  homeCity: mexico
  bio: ''
  contact: !ruby/hash:Hashie::Mash
    email: [e-mail]
unmatched: !ruby/hash:Hashie::Mash
  email: []

i can get the results by typing @response.results, and get debuged this:

---
- !ruby/hash:Hashie::Mash
  id: '33098557'
  firstName: john
  lastName: star
  relationship: self
  photo: https://foursquare.com/img/blank_boy.png
  tips: !ruby/hash:Hashie::Mash
    count: 0
  lists: !ruby/hash:Hashie::Mash
    groups:
    - !ruby/hash:Hashie::Mash
      type: created
      count: 1
      items: []
  gender: male
  homeCity: mexico
  bio: ''
  contact: !ruby/hash:Hashie::Mash
    email: [e-mail]

but i cant get the inner attributes like the email or firstname, how can i access those attributes???

Answer 1

@response is an instance of Hashie::Mash, while @response.results is an instance of Array, so you need to access the index of the array you wish to receive a result for.

@response.results[0].firstName
@response.results[0].contact.email

will return the values for firstName and email of the first result respectively. You can loop through the responses (to get all results if there happens to be more than one) with

@response.results.each do |result|
  result.firstName
  result.contact.email
end

If there’s always only one result you can also access this with Ruby’s .first method

@response.results.first.email
