Requirements

  • python >= 2.7
  • pubnub_blocks_client >= 1.0

Parameters

Parameter Choices/Defaults Comments
account
(added in 2.4)
Name of PubNub account for from which application will be used to manage blocks.
User's account will be used if value not set or empty.
application
required
Name of target PubNub application for which blocks configuration on specific keyset will be done.
cache Default:
{}
In case if single play use blocks management module few times it is preferred to enabled 'caching' by making previous module to share gathered artifacts and pass them to this parameter.
changes Default:
{}
List of fields which should be changed by block itself (doesn't affect any event handlers).
Possible options for change is: name.
description Default:
New block
Short block description which will be later visible on admin.pubnub.com. Used only if block doesn't exists and won't change description for existing block.
email
Email from account for which new session should be started.
Not required if cache contains result of previous module call (in same play).
event_handlers Default:
[]
List of event handlers which should be updated for specified block name.
Each entry for new event handler should contain: name, src, channels, event. name used as event handler name which can be used later to make changes to it.
src is full path to file with event handler code.
channels is name of channel from which event handler is waiting for events.
event is type of event which is able to trigger event handler: js-before-publish, js-after-publish, js-after-presence.
Each entry for existing handlers should contain name (so target handler can be identified). Rest parameters (src, channels and event) can be added if changes required for them.
It is possible to rename event handler by adding changes key to event handler payload and pass dictionary, which will contain single key name, where new name should be passed.
To remove particular event handler it is possible to set state for it to absent and it will be removed.
keyset
required
Name of application's keys set which is bound to managed blocks.
name
required
Name of managed block which will be later visible on admin.pubnub.com.
password
Password which match to account to which specified email belong.
Not required if cache contains result of previous module call (in same play).
state
    Choices:
  • started ←
  • stopped
  • present
  • absent
Intended block state after event handlers creation / update process will be completed.
validate_certs Default:
yes
This key allow to try skip certificates check when performing REST API calls. Sometimes host may have issues with certificates on it and this will cause problems to call PubNub REST API.
If check should be ignored False should be passed to this parameter.

Return Values

Common return values are documented here, the following are the fields unique to this module:

Key Returned Description
module_cache
dict
 always
Cached account information. In case if with single play module used few times it is better to pass cached data to next module calls to speed up process.


Status

This module is flagged as preview which means that it is not guaranteed to have a backwards compatible interface.
