Setting Rating from JSON file

[sebutzu]

calling exiftool with:

Code Select Expand

-fast -m -q -q -charset filename=UTF8 -d "%Y.%m.%d %H:%M:%S" -c "%.8f" -s -G:0:1 -a -all -use mwg -api largefilesupport=1 -overwrite_original -P -v3 -f -j="C:\Users\sebas\AppData\Local\Temp\tmpupmrcr.tmp"  "C:/Work/test photos/2022-03-05 12.16.14 0001.jpg"where the file contains:

Code Select Expand

[
  {
    "SourceFile": "C:/Work/test photos/2022-03-05 12.16.14 0001.jpg",
    "Composite:MWG:Rating": 4
  }
]
gives me:

Code Select Expand

Please help, I do not know what am I doing wrong...
I would expect to set the value of rating...but it just gives me Nothing changed...

Code Select Expand

> exiftool a.jpg -composite:mwg:rating=1
Warning: Sorry, composite:mwg:Rating doesn't exist or isn't writable
Nothing to do.
> exiftool a.jpg -mwg:rating=1

I should probably look into why this doesn't work with the Composite group specified.

Ah I see:

Code Select Expand

> exiftool -use mwg a.jpg -composite:mwg:rating=1
    1 image files updated
The MWG module isn't being loaded automatically when "Composite" comes first.  I should be able to fix this.

- Phil

Edit: I've patched this and ExifTool 13.12 will fix this issue.

I have -use mwg in my command...

[Phil Harvey]

Right.  So this is a different problem.

Your command works when I remove -all.

(Something else that could be fixed)

[sebutzu]

Yes, removing all makes it work, thanks a lot!

I've looked into this...

The documentation doesn't state that wildcards and/or "all" may be used when specifying tags to import from a JSON file, but adding support for "all" is easy so I'll do that (even though it is completely unnecessary because this is the default).  But other wildcards still won't be supported.
