Payload automatically manages relational data using PostgreSQL under the hood. The relationships will be stored as JSON fields containing references to related documents.
const user = await payload.find({
collection: “users”,
where: {
id: { equals: “USER_ID” },
},
depth: 2, // Fetch nested relationships
});
console.log(user);
Use depth in API calls to fetch nested relational data efficiently.
Set unique: true for one-to-one relationships to ensure data integrity.
Use hasMany: true for one-to-many and many-to-many relationships.
Create indexes in PostgreSQL for frequently queried fields to optimize performance.
