Hello @Jeff_Hager , out of curiosity I wanted to ask if it’s possible to generate codes such as this upon a button press only, or once generated, is automatically stored into a separate column without any button inputs.

My use-case is that this computed field takes a long time to load, especially when I’m displaying a large list of records. So instead of the computed field working automatically, I was thinking if it would be possible to only generate thumbnails when I press a button (e.g. called “Generate thumbnail”). Does Glide have any features like this?

The problem is that computed columns are generated in every session. So I’m thinking that once I press the button mentioned above, it could generate (or copy & paste) the thumbnail into an “Image” column, so that the thumbnail is stored as part of the record, and it won’t need to be computed every time the record is displayed.

In the simplest form, you could leave it as part of your table, and then have a button the copies the result to a different column.

You could also probably have it as part of a custom form when adding rows, and then write the result to the destination table when you submit the form.

I suppose you could probably use some external service if it allows you to process code and return a result.

A lot of ways to approach it, but I guess it all comes down to how rows are added, or how a video is uploaded or linked, and when in the process you would want to save the permanent image uri.
