  Hi @Lloyd useAsTitle does not support nested fields currently, we will commonly use a virtual field to get specific data for your document title. For example:

  
  
  

      {
        name: 'title',
        type: 'text',
        admin: {
          hidden: true,
        },
        hooks: {
          beforeChange: [
            ({ data }) => {
              return data.course.title;
            }
          ],
        },
      },

  
  
  

  Then you would set

  useAsTitle: 'title'

  Hi, it seems like a really good solution, thanks a lot!

  
  
  

  I've encountered only one problem, in my case

  data.course.title

  did not contain the title of the course, here's the output of

  data

  :

  
  

  {
    tier: 'base',
    user: '63c66090c20a548b1c0a325b',
    title: '',
    course: '63f4835d1c09415657bfccff'
  }

  
  

  But I fetched it like this

  
  

      {
        name: 'title',
        type: 'text',
        admin: {
          hidden: true
        },
        hooks: {
          beforeChange: [
            async ({data}) => {
              const req = await fetch(`${process.env.URL}/api/courses/${data.course}`)
                .then(res => res.json())
                .then(data => {
                  return data.title
                })
              return req
            }
          ]
        }
      }

  
  
  

  And now everything works well
