PicklePersistence

class telegram.ext.PicklePersistence(filepath, store_data=None, single_file=True, on_flush=False, update_interval=60, context_types=None)

Bases: telegram.ext.BasePersistence

Using python’s builtin pickle for making your bot persistent.

Attention

The interface provided by this class is intended to be accessed exclusively by Application. Calling any of the methods below manually might interfere with the integration of persistence into Application.

Note

This implementation of BasePersistence uses the functionality of the pickle module to support serialization of bot instances. Specifically any reference to bot will be replaced by a placeholder before pickling and bot will be inserted back when loading the data.

Examples

Persistent Conversation Bot

Use In

telegram.ext.ApplicationBuilder.persistence()

Available In

Making Your Bot Persistent

Changed in version 20.0:

• The parameters and attributes store_*_data were replaced by store_data.

• The parameter and attribute filename were replaced by filepath.

• filepath now also accepts pathlib.Path as argument.

Parameters:

• filepath (str | pathlib.Path) – The filepath for storing the pickle files. When single_file is False this will be used as a prefix.

• store_data (PersistenceInput, optional) – Specifies which kinds of data will be saved by this persistence instance. By default, all available kinds of data will be saved.

• single_file (bool, optional) – When False will store 5 separate files of filename_user_data, filename_bot_data, filename_chat_data, filename_callback_data and filename_conversations. Default is True.

• on_flush (bool, optional) – When True will only save to file when flush() is called and keep data in memory until that happens. When False will store data on any transaction and on call to flush(). Default is False.

• context_types (telegram.ext.ContextTypes, optional) –

  Pass an instance of telegram.ext.ContextTypes to customize the types used in the context interface. If not passed, the defaults documented in telegram.ext.ContextTypes will be used.

  Added in version 13.6.

• update_interval (int | float, optional) –

  The Application will update the persistence in regular intervals. This parameter specifies the time (in seconds) to wait between two consecutive runs of updating the persistence. Defaults to 60 seconds.

  Added in version 20.0.
