Overview
Relation fields connect records from different objects—for example, linking People to Companies.Relation names cannot be changed after creation (they affect the API). Plan your names carefully.
Before You Start
Decide:- Which objects are you connecting? (e.g., People → Companies)
- Which is the “one” side? (e.g., Company)
- Which is the “many” side? (e.g., People — many people work at one company)
- What should the field be named on each side?
Steps
- Go to Settings → Data Model
- Select the object where you want the relation (typically the “many” side)
- Click + New Field
- Select Relation as the field type
- Choose the target object
- Select One-to-Many or Many-to-One
- Enter field names for both sides of the relation
- Click Save
Example: People → Companies
- Go to Settings → Data Model → People
- Add a Relation field
- Target: Companies
- Type: Many-to-One
- Field on People: Company
- Field on Companies: Employees
