Photo naming error (QField)

Question

Follow the instructions at https://qfield.org/docs/prepare/picture_path.html?highlight=photo

I write the following route to "Photo naming":

'DCIM / INV / INV_' || (now () || '.jpg'

But it only generates a DCIM folder with all the photos and named JPEG ... as if it wasn't set up:

DCIM / JPEG_20210924091021590.jpg

Where is the error? Do I need to do something else?

Answer 1

There is an superfluous parenthesis before now(), i.e. you have '(now ()' The additional white spaces are also confusing. Try

'DCIM/INV/INV_'||now()||'.jpg'

or if you want to format your date so it is more readable, something like

'DCIM/INV/INV_'||format_date(Now(), 'yyyy-MM-dd_hhmmss')||'.jpg'
