Duplicate role

Role is duplicated by RoleDuplicateBulkAction bulk action. This action propagate DUPLICATE event type with content:

  • original source - contains the selected original role
  • content - contains duplicated role

Creating duplicate role is then propagated into registered (and enabled) entity event processors. Custom processors can be registered by the different module (or product processor can be disabled and overriden, see below).

Processors can register form attributes into the bulk action form - distinct form attributes (by code, the first attribute wins by processor's order) are rendered and used as input for the bulk action.

Form attributes registered by processor can be localized in the custom module. Each attribute can have different module - module is preset automatically by the processor's module.
If role is duplicated into different environment and role with the same base code already exists there, then new role on the target environment is not created, but updated by the source (selected) role. E.g. when some basic role attribute is changed or some automatic role is added ⇒ this changes can be "synchronized" into target role repetitively. Roles are paired between environments by the base code ⇒ if base code is changed, then new duplicate will be created.

Processors

Implemented processors in the product sorted by order of the processing:

DuplicateRolePrepareProcessor

@since 9.5.0

  • Event content: IdmRoleDto
  • Event type: DUPLICATE
  • Default order: -1000

Prepares role's basic properties.

Register custom processor after this processor's order, if some role basic property has to be overriden (or filled by different business logic). 
## Enable / disable
idm.sec.core.processor.core-duplicate-role-prepare-processor.enabled=true

DuplicateRoleSaveProcessor

@since 9.5.0

  • Event content: IdmRoleDto
  • Event type: DUPLICATE
  • Default order: 0

Here is the role persisted into database.

Register custom processor after this processor's order, if some related entities has to be duplicated (e.g. guarantees). 
## Enable / disable
idm.sec.core.processor.core-duplicate-role-save-processor.enabled=true

DuplicateRoleFormAttributeProcessor

@since 9.5.0

  • Event content: IdmRoleDto
  • Event type: DUPLICATE
  • Default order: 50

Duplicate role form attributes - parameters for the identity (~assigned) roles. Parameters are created for the target role or updated - extended attribute code is used for pairing.

Parameters provided to the bulk action form:

  • Duplicate role form attributes - if role form attributes will be duplicated.

Configuration properties: 

## Enable / disable
idm.sec.core.processor.core-duplicate-role-form-attribute-processor.enabled=true

DuplicateRoleCompositionProcessor

@since 9.5.0

  • Event content: IdmRoleDto
  • Event type: DUPLICATE
  • Default order: 100

Duplicate configured role composition (sub roles by business role definition) and duplicate sub roles recursively. If the same environment is selected, the only role composition is created - existing sub roles are used. If the different environment (~target environment) is used, then sub roles with the same environment as original are duplicated recursively into target environment.

Parameters provided to the bulk action form:

  • Duplicate sub roles (by business role definition) - if business role configuration will be duplicated (recursively).

Overidable methods (can be used for on the projects, e.g. example below):

  • duplicateRecursively - Returns true, when role should be cloned recursively - can be overriden, if some role hasn't be cloned recursively, if doesn't exist on the target environment before.
  • includeComposition - Returns true, when role composition should be included in the target role - can be overriden, if some role hasn't be cloned recursively, if doesn't have the same environment etc.

Configuration properties: 

## Enable / disable
idm.sec.core.processor.core-duplicate-role-composition-processor.enabled=true

Custom processor example

Core processor can be disabled and overriden by processor implemented in custom module, if behavior of the core processor has to be changed. 

/**

	}
}

DuplicateRoleAutomaticByTreeProcessor

@since 9.5.0

  • Event content: IdmRoleDto
  • Event type: DUPLICATE
  • Default order: 200

Duplicate configured automatic roles by tree structure. Automatic roles are duplicated recursively, if composition is duplicated recursively (see DuplicateRoleCompositionProcessor above).

Parameters provided to the bulk action form:

  • Duplicate automatic roles - if automatic roles will be duplicated (both by tree structure and attribute).

Configuration properties: 

## Enable / disable
idm.sec.core.processor.core-duplicate-role-automatic-by-tree-processor.enabled=true

DuplicateRoleAutomaticByAttributeProcessor

@since 9.5.0

  • Event content: IdmRoleDto
  • Event type: DUPLICATE
  • Default order: 300

Duplicate configured automatic roles by attribute. Automatic roles are duplicated recursively, if composition is duplicated recursively (see DuplicateRoleCompositionProcessor above).

Parameters provided to the bulk action form:

  • Duplicate automatic roles - if automatic roles will be duplicated (both by tree structure and attribute).

Example processor

Processors can be registered to process event with type DUPLICATE and IdmRoleDto content. 

/**
 * Duplicate role - example processor, just create log
 */

}

Entity state usage

When some role composition or automatic role (~related entity) is removed from the source role and role is duplicated into different environment repetitively (⇒ update), then all removed related entities are removed at the end of the bulk action to prevent some account on target system (acc) will be removed and created again. When bulk action is processed (by processors) and some related entity has to be removed, then entity state deleted is created for this entity only. All entities with the deleted state are removed at end. States are marked with transactionId, which creates envelope for all states creates by one bulk action ⇒ only states for the current bulk action are processed.
