Elide Java @ComputedRelationship computed relationship getter semantics
💡 Result:
In Elide, the @ComputedRelationship annotation is used to mark a field or method as a relationship whose value is computed in code rather than retrieved directly from a persistent data store [1][2]. Its primary semantic purpose is to ensure that Elide exposes the relationship through its API, even if the underlying field or method is marked as @Transient (which would otherwise cause it to be ignored by data store frameworks like Hibernate) [2][3]. Key semantics and usage include: 1. Exposure: When a field or method is annotated with @ComputedRelationship, Elide includes it in the exposed data model [1][2]. This is critical for scenarios where the data is derived, such as traversing a relationship chain or performing logic to determine a related entity [2][4]. 2. Compatibility: It is frequently used in conjunction with @Transient to prevent persistence layers from attempting to map or store the computed value while allowing the Elide API to serve it [2][4]. 3. Implementation: The method annotated with @ComputedRelationship should contain the necessary logic to calculate or return the related entity [2][4]. For example, a common pattern involves checking for the existence of an object and then returning a property or sub-relationship from that object [4]. 4. Applicability: The annotation can be applied to both fields and methods [1][5]. In essence, @ComputedRelationship acts as an override instruction to Elide, telling the framework to treat a computed value as a formal relationship in the API schema regardless of its transient status in the database layer [2][3].

site:elide.io/pages/guide/v7 @ComputedRelationship getter method computed relationship
💡 Result:
The @ComputedRelationship annotation is a feature provided by the Elide framework used to mark a field or a method as a computed relationship [1][2]. This annotation allows developers to define custom relationships that are computed at query time rather than being retrieved directly from a persistent data store [3]. When you apply @ComputedRelationship to a getter method, it instructs Elide to expose that method as a relationship in the API, even if the field or method is marked as @Transient [1][2]. This is particularly useful for scenarios where you want to include data in your API model that is generated or calculated in the JVM but is not stored in the underlying database [2]. For example, if you annotate a getter method with @Transient to ensure Hibernate ignores it, adding @ComputedRelationship ensures that Elide still exposes this as a relationship in your API schema [2]. The annotation can be applied at the field or method level [1].

Populate reviewRequests before exposing the computed relationship.
Game.getReviewRequests() only returns the transient reviewRequests field. No code assigns this field, and GameEnricher does not populate it. GameReviewRequest stores only the forward game reference and uses the ephemeral no-op datastore. Therefore, an Elide read cannot obtain review requests from this relationship. Add a population path and an integration test for create-then-read behavior.

Return a unique resource ID.
GameReviewRequest.getId() is annotated with @Id but always returns "N/A". Elide exposes Game.getReviewRequests() as a @ToMany relationship, so multiple requests cannot have distinct resource identities. Clients cannot reliably address or retrieve an individual request.
Store a generated unique ID in GameReviewRequest, or use the ephemeral datastore's supported ID mechanism. Add an integration test that creates two requests for one game and verifies distinct IDs.

site:elide.io documentation JSON API nested create relationship @CreatePermission @ToMany``
💡 Result:
In the Elide framework, which implements JSON API, the annotations @CreatePermission and @ToMany are used to define security and relationship structures, respectively [1][2]. @ToMany The @ToMany annotation is a non-JPA relationship annotation used to mark a field or method as a "to-many" relationship that should be exposed through the Elide API [1][2]. It is essential for defining the entity-relationship graph that the API traverses [2]. @CreatePermission The @CreatePermission annotation defines the security rules for creating an object or initializing a field in a newly created model instance [1][3]. When a new model instance is created, initialized fields are evaluated against the @CreatePermission check rather than the @UpdatePermission check [3][4]. This annotation can be applied at the package, entity (class), or field level, with the most specific annotation taking precedence [3]. Nested Relationships Elide supports arbitrarily deep nested relationships in URLs [5][6]. While JSON API allows fetching primary collections and including nested relationships via the include query parameter, Elide currently requires that all individual entities be addressed by their ID within a URL path (e.g., /articles/1/author/34/address instead of /articles/1/author/address) [5][6]. To handle complex or bulk mutations involving nested objects, Elide supports extensions like Atomic Operations or JSON Patch, which allow bundling multiple operations into a single request [5][6]. For newly created objects, if the server generates the IDs, clients can use a local ID (lid) in the request to maintain relationships [5].

Authorization Bypass
Reachability: External
Exploitability: Moderate
CWE: CWE-639 — Authorization Bypass Through User-Controlled Key (IDOR)
Do not derive ownership from a client-selected Player.
GameReviewRequest exposes a writable player relationship and maps getEntityOwner() to that value. An authenticated client can submit a nested create request with another Player, while @CreatePermission(expression = Prefab.ALL) does not bind player to the authenticated principal.
Set player from the authenticated principal during creation and reject payload-supplied player values. Add an integration test that creates a request as Player A with Player B in the payload. The request must be rejected or owned by Player A.
