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 activesupport/lib/active_support/json/encoding.rb, line 19
def self.encode(value, options = nil)
Encoding.json_encoder.new(options).encode(value)
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 activesupport/lib/active_support/json/decoding.rb, line 40
def parse_error
::JSON::ParserError
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
