class Faker::Json
Public Class Methods
Produces a random nested JSON formatted string that can take JSON as an additional argument.
@param json [Hash{String => String}] Specifies a Json.shallow_json
and uses its keys as keys of the nested JSON. @param width [Integer] Specifies the number of nested key-value pairs. @param options [Hash] Specifies a Faker
gem class to use for nested keys and for values, respectably. options_hash = {key: Class.method, value: Class.method} @return [Hash{String => String}]
@example
json = Faker::Json.shallow_json(width: 3, options: { key: 'Name.first_name', value: 'Name.last_name' }) puts json # => {"Alisha":"Olson","Everardo":"DuBuque","Bridgette":"Turner"} json2 = Faker::Json.add_depth_to_json(json: json, width: 2, options: { key: 'Name.first_name', value: 'Name.last_name' }) puts json2 # => {"Alisha":{"Daisy":"Trantow","Oda":"Haag"}, "Everardo":{"Javier":"Marvin","Eliseo":"Schuppe"}, "Bridgette":{"Jorge":"Kertzmann","Lelah":"MacGyver"}} json3 = Faker::Json.add_depth_to_json(json: json2, width: 4, options: { key: 'Name.first_name', value: 'Name.last_name' }) puts json3 # => {"Alisha": {"Daisy": {"Bulah":"Wunsch","Cristian":"Champlin","Lester":"Bartoletti","Greg":"Jacobson"}, "Oda": {"Salvatore":"Kuhlman","Aubree":"Okuneva","Larry":"Schmitt","Velva":"Gibson"}}, "Everardo": {"Javier": {"Eduardo":"Orn","Laila":"Kub","Thad":"Legros","Dion":"Wilderman"}, "Eliseo": {"Olin":"Hilpert","Marisa":"Greenfelder","Karlee":"Schmitt","Judd":"Larkin"}}, "Bridgette": {"Jorge": {"Eloy":"Pfeffer","Kody":"Hansen","Paxton":"Lubowitz","Abe":"Lesch"}, "Lelah": {"Rick":"Wiza","Bonita":"Bayer","Gardner":"Auer","Felicity":"Abbott"}}}

Produces a random simple JSON formatted string.
@param width [Integer] Specifies the number of key-value pairs. @param options [Hash] Specifies a Faker
gem class to use for keys and for values, respectably. options_hash = {key: Class.method, value: Class.method} @return [Hash{String => String}]
@example
Faker::Json.shallow_json(width: 3, options: { key: 'RockBand.name', value: 'Seinfeld.quote' }) # => {"Parliament Funkadelic":"They're real, and they're spectacular.", "Fleetwood Mac":"I'm not a lesbian. I hate men, but I'm not a lesbian.", "The Roots":"It became very clear to me sitting out there today that every decision I've made in my entire life has been wrong. My life is the complete opposite of everything I want it to be. Every instinct I have, in every aspect of life, be it something to wear, something to eat - it's all been wrong."}
