node.actions.rules

NodeActionsRules : d2/sdk/commands/node.actions.rules

Action rules collection. Each rule binds a D2SV menu action to a CommandModel by mapping through it's signature. So that when the menu action is selected by end user from a menu toolbar, business logic from the mapped CommandModel is executed. If a NodeModel is found to have a menu action that is not mapped to any CommandModel's signature, the menu action is ignored.

D2SV application runtime pre-defines many such mappings for OOTB business actions.

One or more rules, to map new actions, could be added to this collection by means of extension.

Extends: Array
See: RulesMatchingMixin for a complete guide on how to write rules.
Example (to register an extension, add in extension.json)

{
  "d2/sdk/commands/node.actions.rules": {
     "extensions": {
        "mybundle": {
           "mybundle/commands/my.node.actions.rules"
        }
     }
   }
}

Example (whereas my.node.actions.rules.js is defined as)

define([], function(){
   'use strict';

   return [
     {
       command_key: 'D2-OpenUrl', //`signature` from a CommandModel implementation
       equals: {action: 'D2_ACTION_OPEN_URL'},
       iconName: 'd2_action_open_url'
     },
     {
       command_key: 'Delete',
       decides: function(item) {
         return item.action === 'D2_ACTION_EXECUTE_MANAGER' &&
           item.actionParameters && item.actionParameters.MANAGER === 'DestroyManager';
       },
       iconName: 'd2_action_delete' // The icon to use when this action is shown in a toolbar with icon.
     }
   ];
});
