A question about sort order: What is a good way of sorting list items by a child field? I have a

Registration

document that references

Program

(so people can register to a program). I’d like to sort registrations by

program.startDate

. Is this possible with

orderings

? The following produces an error:

orderings: [
  {
    title: 'Program date',
    name: 'programDate',
    by: [{ field: 'program.startDate', direction: 'descending' }]
  },
]

Thanks!

UPDATEI made a typo (

descending

should be

desc

), that’s why it didn’t work.

Ah… I made a mistake there:

direction

should be

desc

and not

descending

. Fixing this fixes my sort issue.
