Overview
Base class to create update processors. With callbacks, session and helpers.
Public methods ending with ‘!` handle messages with commands. Message text is automatically parsed into method arguments. Be sure to use default values and splat arguments in every action method to not get errors, when user sends command without necessary args / with extra args.
def start!(token = nil, *)
if token
# ...
else
# ...
end
end
def help!(*)
respond_with :message, text:
end
To process plain text messages (without commands) or other updates just define public method with name of payload type. By default they receive payload as an argument, but some of them are called with more usefuk args:
def ()
respond_with :message, text: "Echo: #{['text']}"
end
def inline_query(query, offset)
answer_inline_query results_for_query(query, offset), is_personal: true
end
To process update run:
ControllerClass.dispatch(bot, update)
There is also ability to run action without update:
ControllerClass.new(bot, from: telegram_user, chat: telegram_chat).
process(:help, *args)

Second argument can be either update object with hash access & string keys or Hash with ‘:from` or `:chat` to override this values and assume that update is nil.
-
#process(action, *args) ⇒ Object
It provides support for passing array as action, where first vaule is action name and second is action metadata.

#action_for_payload ⇒ Object
Calculates action name and args for payload. Uses ‘action_for_#payload_type` methods. If this method doesn’t return anything it uses fallback with action same as payload type. Returns array ‘[action, args]`.

#action_type ⇒ Object
There are multiple ways how action name is calculated for update (see Commands, MessageContext, etc.). This method represents the way how action was calculated for current udpate.
Some of possible values are ‘:payload, :command, :message_context`.

# File 'lib/telegram/bot/updates_controller.rb', line 178 def action_type [:type] || :payload end |
#chat ⇒ Object
Accessor to ‘’chat’‘ field of payload. Also tries `’chat’‘ in `’message’‘ when there is no such field in payload.
Can be overriden with ‘chat` option for #initialize.
