Variable "Send to device" path

[cipesek]

Hi everybody,
I want my calibre to find out if book comes in series and accordingly to answer choose from saving it to "author_sort" folder or "_series_" folder....please - where I catch wrong grip?

{series:'test($,
strcat("Knihy/_",field("series"),"_/",field("series_index"),". ",field("title")," (",field("author"),")"),
strcat("Knihy/",field("author_sort"),"/",field("title")," (",field("author"),")"))'}

PS: Even start may be wrong using "series" as output variable, but I couldn't use #var from some reason i don't get....

I tried using your template in a custom column and it produced a result, so it isn't clear what your problem is. What problem are you are having? Where are you using that template when it doesn't do whatever you want?

As an aside, you might be better off using something like

{series:'test($,
template("Knihy/_[[series]]_/[[series_index]].[[title]] ([[author]])"),
template("Knihy/[[author_sort]]/[[title]] ([[author]])"))'}

Expressing the result as a template evaluation seems clearer to me than doing it as a series of concatenated values.

Even better (for me) would be to use general program mode, letting you use {} instead of [[ ]] to bracket field references in the template.

program:
test(field('series'), 
	template("Knihy/_{series}_/{series_index}.{title} ({author})"),
	template("Knihy/{author_sort}/{title} ({author})"))

THANX A LOT! ..."general program" shows some error, but "[[]]" code works smoothly

BTW: problem was program dont accepted my template and used last working template instead...

PS: can I somehow detect biggest "series_index" for book in selected series, to automatically choose number of prefix zeros before series number? (e.g.: if in series of transfered book is some book labeled like "195-th part", than use for series_index 3 digits...) ....its no big deal, but for series like Coollorado westerns, Perry Rhodan, Ren Dhark.... there are tens/houndreds of storyes )

What error?

No. Templates operate on one book at a time. There is no way to get information that requires scanning the database.

Thank you. That helped find a bug when using GPM templates in save-to-disk.
