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.

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
boolean
    Choices:
  • no
  • 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
dictionary
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.
