module ActiveSupport::JSON

Parses a JSON string (JavaScript Object Notation) into a hash. See www.json.org for more info.

ActiveSupport::JSON.decode("{\"team\":\"rails\",\"players\":\"36\"}")
=> {"team" => "rails", "players" => "36"}

# File lib/active_support/json/decoding.rb, line 21
def decode(json)
  data = ::JSON.parse(json, quirks_mode: true)

  if ActiveSupport.parse_json_times
    convert_dates_from(data)
  else
    data
  end
end

Dumps objects in JSON (JavaScript Object Notation). See www.json.org for more info.

ActiveSupport::JSON.encode({ team: 'rails', players: '36' })
# => "{\"team\":\"rails\",\"players\":\"36\"}"

# File lib/active_support/json/encoding.rb, line 20
def self.encode(value, options = nil)
  Encoding.json_encoder.new(options).encode(value)
end

Returns the class of the error that will be raised when there is an error in decoding JSON. Using this method means you won't directly depend on the ActiveSupport's JSON implementation, in case it changes in the future.

begin
  obj = ActiveSupport::JSON.decode(some_string)
rescue ActiveSupport::JSON.parse_error
  Rails.logger.warn("Attempted to decode invalid JSON: #{some_string}")
end

# File lib/active_support/json/decoding.rb, line 41
def parse_error
  ::JSON::ParserError
end
