How to use a Custom Preview Component on the Document View

15 replies
Last updated: Apr 21, 2020
how do I use a custom preview component on the document view?
Apr 21, 2020, 5:46 PM
say i have an document 
video
that i want to show the video preview on the document view
i also reference this video in another document, but when its a reference, I only want to show the 
video
document title
how is this accomplished?

Just to confirm I’m understanding fully, you have a custom preview component for your 
video
document type, e.g. something like on https://www.sanity.io/guides/portable-text-how-to-add-a-custom-youtube-embed-block . You’re happy to show this preview in 
video
, but when you add a reference to the document type you don’t want to see it. Is that correct? What kind of preview does the reference currently show?

yes...

Video document... would like the preview here
Apr 21, 2020, 6:13 PM
When referenced ... this is fine
Apr 21, 2020, 6:13 PM
the reason the reference looks ok, is because I removed the 
preview
from the schema, otherwise it was trying to load the videoPreview component

Thanks for the shots, always helps! 🙂 Have you considered adding a video object to your video document (under a different name)? That should let you show the preview on the document but just the title in the reference 📽️
This would require loading the preview component in the object instead.

i had not considered that ... so making a 
video
object that goes inside the 
video
document. does the object only contain the URL for the video? (i'm sourcing from vimeo)
Apr 21, 2020, 7:50 PM
Yep, I’d say so, unless you want to add more data that specifically belongs to the video like a title or caption etc.
Apr 21, 2020, 7:54 PM
well, i would think i could just use the 
document
title... since the document is really about the video
Apr 21, 2020, 7:55 PM
One thing you could consider is whether you need that kind of data in the document where you reference the video.
Apr 21, 2020, 8:05 PM
been thinking the same thing ...
Apr 21, 2020, 8:06 PM
99% of the time, i'm probably also the document editor, and i'll know the video already
Apr 21, 2020, 8:06 PM
however, i do see a scenario down the road where I use this dataset as a source for another Sanity project, and the people using that project will need a visual reference to what the video looks like
