Iterate JSON array and find all matched values

Question

So I am trying to find all elements within the json array below with an email with the domain example.com

JSON Array used:

[{"addedAt"=>123456,
  "vid"=>123456,
  "canonical-vid"=>123456,
  "merged-vids"=>[],
  "portal-id"=>123456,
  "is-contact"=>true,
  "profile-token"=>"portal-token-goes-here",
  "profile-url"=>"portal-url-goes-here",
  "properties"=>{"firstname"=>{"value"=>"Ramon"}, "lastmodifieddate"=>{"value"=>"12345"}, "company"=>{"value"=>"Some Company"}, "lastname"=>{"value"=>"Carleones"}},
  "form-submissions"=>
   [{"conversion-id"=>"some-convo-id-goes-here",
     "timestamp"=>123456,
     "form-id"=>"form-id-goes-here",
     "portal-id"=>405406,
     "page-url"=>"page-url-goes-here",
     "content-type"=>"standard-page",
     "page-title"=>"page-title-goes-here",
     "title"=>"title-goes-here",
     "first-visit-url"=>"first-visit-url-goes-here",
     "first-visit-timestamp"=>123456,
     "meta-data"=>[]}],
  "identity-profiles"=>
   [{"vid"=>123456,
     "saved-at-timestamp"=>123456,
     "deleted-changed-timestamp"=>0,
     "identities"=>[{"type"=>"EMAIL", "value"=>"ramon@example.com", "timestamp"=>123456}, {"type"=>"Important", "value"=>"some-value", "timestamp"=>123456}]}],
  "merge-audits"=>[]},
 {"addedAt"=>123456,
  "vid"=>123456,
  "canonical-vid"=>123456,
  "merged-vids"=>[],
  "portal-id"=>123456,
  "is-contact"=>true,
  "profile-token"=>"portal-token-goes-here",
  "profile-url"=>"profile-url-goes-here",
  "properties"=>{"firstname"=>{"value"=>"Sally"}, "lastmodifieddate"=>{"value"=>"123456"}, "company"=>{"value"=>"Acme Inc."}, "lastname"=>{"value"=>"Jackson"}},
  "form-submissions"=>
   [{"conversion-id"=>"some-convo-id-goes-here",
     "timestamp"=>123456,
     "form-id"=>"some-form-id",
     "portal-id"=>123456,
     "title"=>"Big Freakin Title",
     "meta-data"=>[]}],
  "identity-profiles"=>
   [{"vid"=>123456,
     "saved-at-timestamp"=>123456,
     "deleted-changed-timestamp"=>0,
     "identities"=>[{"type"=>"EMAIL", "value"=>"sjackson@acme-example.com", "timestamp"=>123456}, {"type"=>"Team Lead", "value"=>"some-value", "timestamp"=>123456}]}],
  "merge-audits"=>[]
  }]

Here is the code I was trying: I used factory girl and used an instance variable:

#@json_array.contacts_obtained is a hash - contacts_obtained is the key, and the 
#value is the actual json array above.

      @json_array.contacts_obtained.detect do |i| i['identity-profiles'][0]['identities'][0]['value'] == /@example.com/
puts i
end

I wasn't sure if it was ok to do a regex there like that. It doesn't appear to work when I tried that. So I was wondering if there was another way to do this.

I am trying to obtain all the elements with @example.com domain so I can 'pop' them or remove them from the json array. Essentially I need a filter. That will filter out all the array elements with certain domain emails.

Answer 1

You are almost there. Use =~ instead of == iy ou want to match a string with a regexp:

@json_array.contacts_obtained.select do |i| 
  i['identity-profiles'][0]['identities'][0]['value'] =~ /@example.com/
end
