Assemble Target Property For JsonLogicEvaluationContext

by ADMIN 56 views

Overview

In the context of ActionValidationService, assembling the target property for JsonLogicEvaluationContext is a crucial step in the validation process. This ticket focuses on populating the target field by conditionally creating the JsonLogicEntityContext for the target (if one exists) and assigning it to the target property of the JsonLogicEvaluationContext.

Goal

The primary goal of this ticket is to conditionally create the JsonLogicEntityContext for the target (if one exists) and assign it to the target property of the JsonLogicEvaluationContext being assembled in ActionValidationService.isValid.

Description

This ticket requires checking if a valid targetEntity was resolved earlier in the isValid method and, if so, creating the context structure similar to the actor, using createComponentAccessor. The evaluationContext object and targetEntity variable should be available for this task.

Tasks

Locate Position

The work for this ticket should be done within ActionValidationService.isValid, after the actor context assembly (Sub-Ticket 3.2.2). The evaluationContext object and targetEntity variable should be available.

Check Target Existence

Add a conditional check to ensure that the targetEntity exists and has an id.

if (targetEntity && targetEntity.id) {
  // Create target context
} else {
  // Handle no target
}

Create Target Context

Inside the if block, create the JsonLogicEntityContext object for the target and assign it to evaluationContext.target.

evaluationContext.target = {
  id: targetEntity.id,
  components: createComponentAccessor(targetEntity.id, this.#entityManager, this.#logger)
};

Log Creation

Add a debug log message confirming target context creation.

this.#logger.debug('Assembled target context for JsonLogic evaluation.', evaluationContext.target);

Handle No Target (Implicit)

If the if condition is false, evaluationContext.target will retain its initial null value (set during initialization in 3.2.2). Add a debug log for this case.

this.#logger.debug('No valid targetEntity found, target context remains null.');

Acceptance Criteria

Valid Target Entity

If targetEntity is a valid entity object, the evaluationContext.target property should be an object containing:

  • An id property matching targetEntity.id.
  • A components property initialized by calling createComponentAccessor with the correct arguments (targetEntity.id, this.#entityManager, this.#logger).

Invalid Target Entity

If targetEntity is null or invalid, evaluationContext.target should remain null.

Debug Messages

Appropriate debug messages should be logged for both cases (target context created vs. target context null).

Code Compilation

The code should compile/run without errors related to this change.

Dependencies

This ticket depends on the following sub-tickets:

  • Sub-Ticket 3.2.1 (Imports)
  • Sub-Ticket 3.2.2 (Initializes evaluationContext)

Estimate

The estimate for this task is small.

Code Implementation

Here is the code implementation for this ticket:

// ActionValidationService.isValid
if (targetEntity && targetEntity.id) {
 evaluationContext.target = {
    id: targetEntity.id,
    components: createComponentAccessor(targetEntity.id, this.#entityManager, this.#logger)
  };
  this.#logger.debug('Assembled target context for JsonLogic evaluation.', evaluationContext.target);
} else {
  this.#logger.debug('No valid targetEntity found, target context remains null.');
}

Example Use Case

Here is an example use case for this ticket:

// ActionValidationService.isValid
const targetEntity = this.#entityManager.find(EntityType, 1);
if (targetEntity && targetEntity.id) {
  evaluationContext.target = {
    id: targetEntity.id,
    components: createComponentAccessor(targetEntity.id, this.#entityManager, this.#logger)
  };
  this.#logger.debug('Assembled target context for JsonLogic evaluation.', evaluationContext.target);
} else {
  this.#logger.debug('No valid targetEntity found, target context remains null.');
}

    id: targetEntity.id,

  };
  this.#logger.debug('Assembled target context for JsonLogic evaluation.', evaluationContext.target);
} else {
  this.#logger.debug('No valid targetEntity found, target context remains null.');
}

Q: What is an example use case for this ticket?

A: Here is an example use case for this ticket:

// ActionValidationService.isValid
const targetEntity = this.#entityManager(EntityType, 1);
if (targetEntity && targetEntity.id) {
  evaluationContext.target = {
    id: targetEntity.id,
    components: createComponentAccessor(targetEntity.id, this.#entityManager, this.#logger)
  };
  this.#logger.debug('Assembled target context for JsonLogic evaluation.', evaluationContext.target);
} else {
  this.#logger.debug('No valid targetEntity found, target context remains null.');
}

In this example, the targetEntity is resolved from the entityManager, and if it exists, the target context is created and logged. If the targetEntity does not exist, a debug message is logged indicating that the target context remains null.
