name	domain-entity-one-to-many-relation-adder
description	Add a one-to-many relation between existing entities and update dependent artifacts; use for prompts like "Add a one-to-many relation ...".

Task preconditions

You MUST NOT generate code if even one of the preconditions is not met.

Identify target entity

Extract the entity name from the request. Check if the entity class exists. Replace placeholder '{Entity}' with the given name. Replace placeholder '{entity}' with kebab case of the the given name. Replace placeholder '{table}' with snake case of the the given name.

Identify relation name

Extract the relation column name from the request. Check if each name is a valid identifier for the programming languages Java, Typescript and SQL. Replace placeholder '{Name}' with the given name. Replace placeholder '{name}' with camel case of the the given name. Replace placeholder '{column}' with snake case of the the given name.

Identify relation type

Extract the relation type from the request. Check if the entity class exists. Replace placeholder '{Type}' with the given type. Replace placeholder '{type}' with camel case of the the given type. Replace placeholder '{otherTable}' with snake case of the the given type.

Identify relation on the other side

Check if the identified relation type has a @ManyToOne relation for this entity.

Task steps

Determine relation semantics

Extract optionality and fetch strategy from the request. If not specified, use defaults from the implementation guide.

Update entity fact sheet {Entity}.adoc

Add a short description for the new relation with its type, constraints, and a one-line description.

Update Liquibase changesets

No changes.

Update entity class {Entity}.java

Use doc/concept/spring/endpoint.adoc as the implementation baseline. Add property with name all{Name} of type Type and annotations. Initialize all{Name} in both constructors. Update operation isEqual. Update operation withId. Add or update operation verify only when requested. Add or update operation extraJson only when requested as it may have negative impact on the performance if relations are involved. Add operation addAll{Name}.

Update entity test class {Entity}Test.java

Use doc/concept/spring/endpoint.adoc as the implementation baseline. If relation is mandatory update existing test data with a default value. Update existing tests with asserts for the new relation.

Update repository interface {Entity}Repository.java

No changes.

Update repository test {Entity}RepositoryTest.java

Use doc/concept/spring/endpoint.adoc as the implementation baseline. If relation is mandatory update existing test data with a default value. Update existing tests with asserts for the new relation. Do not create a new test for the relation.

Update REST API controller class {Entity}RestController.java

No changes.

Update REST API test {Entity}RestApiTest.java

Use doc/concept/spring/endpoint.adoc as the implementation baseline. If relation is mandatory update existing test data with a default value. Update existing tests with asserts for the new relation.

Update GraphQL schema {Entity}.gqls

Use doc/concept/spring/endpoint.adoc as the implementation baseline. Add all{Name}: [{Type}] to GraphQL type {Entity} in {Entity}.gqls with correct nullability. Do not add new queries in Query.gqls.

Update GraphQL controller class {Entity}GraphqlController.java

Use doc/concept/spring/endpoint.adoc as the implementation baseline. Add method all{Name} for batch loading.

Update GraphQL test {Entity}GraphqlTest.java

Update tests for new relation as required in the implementation guide. If relation is mandatory update existing test data with a default value. Update existing tests with asserts for the new relation. Do not create a new test for the relation.

Update Server test set

No changes.
