OneToMany class

OneToMany relationship annotation

Defines a one-to-many relationship between entities. This is the owning side - a FK column will be created in the target entity's table. The FK column name is automatically derived as {ownerTableName}_id (singular, snake_case). The target table name is automatically resolved from the target entity's @Entity annotation.

Example:

// In UserEntity (tableName: 'users') - owns the relationship
// Automatically creates user_id FK column in posts table (resolved from PostEntity's @Entity)
@OneToMany(targetEntity: PostEntity)
List<PostEntity>? posts;

// With explicit FK (if target entity uses a different FK column name):
@OneToMany(
  targetEntity: PurchasesEntity,
)
List<PurchasesEntity>? purchases;
