[Digikam-devel] Renaming imported photos (was: Re: [Bug 106928] Digikam custom filename format from date and time)

[Andreas Mair]

Hi,

this weekend I tried the camera import dialog again.
This time I tried to also add the folders where the photos should be stored. 
I've organised my photos in folders like <digiKam photo 
path>/<year>/<month>/<photos>.jpg
So I tried to set the filename pattern to "%Y/%m/%Y-%m-%d_%%02d". But I 
couldn't manage to get this work :(

So my question:
Am I supposed to store all my photos in a single folder? Well, that's not 
what I want...

Any change to get this feature?

But this simply adds a sequence number to every imported picture. It does 
not check if it's really needed.
Above that: what happens if the destination file already exists?

Would it be possible to get an option for getting unique filenames that 
calculates the appended number from the destination filename? So if there's 
no file matching "2005-07-01_???.jpg" name it "2005-07-01_001.jpg" but if 
some exist name it "2005-07-01_<next free sequence number>.jpg".

Maybe this can be presented on the GUI by a "Keep filenames unique" 
selectbox having the options "across all files", "in folder", "using per 
file sequence".
Where "across all files" should number all images known to digiKam uniquely. 
"in folder" would use a unique sequence number per folder. And "using per 
file sequence" will do what I tried to explain above.
Maybe this select box can have a "no" option to disable adding a sequence 
number.
