The relationship field in Payload CMS is a powerful feature that allows you to connect data between different collections, similar to foreign keys in relational databases. This enables the creation of complex, interconnected data models with ease, making it ideal for building scalable, content-driven applications.
How It Works
- Reference Entries: Link items from one collection to another.
- Filter Data: Limit the options shown based on criteria.
- Display Relationships: Easily retrieve and display related data in your frontend.
Example: Linking Authors to Posts
const Posts = {
slug: 'posts',
fields: [
{
name: 'title',
type: 'text',
required: true,
},
{
name: 'author',
type: 'relationship',
relationTo: 'authors',
required: true,
},
],
};
export default Posts;
Benefits of the Relationship Field
- Simplified Data Modeling: Easily link and manage complex content structures.
- Reusability: Reference existing records without duplicating data.
- Consistency: Maintain data integrity with robust relational links.
