Kobo Libra2: template collections not created

chaley · 05-31-2022, 10:25 AM

I use this template to create collections.

Code:

program:
	globals(serial_number='N4181B1027108');

	if serial_number == 'N4181B1027108' then
		return list_join(
			':@:', 
			list_re($#cbhtags, ',', '^(.*)$', 'CBH Tags: \1'), ',', 
			list_re($authors, '&', '(^.).*', 'Authors: \1'), '&')
	fi;
	if serial_number == 'N4181B5019336' then
		return list_join(
			':@:', 
			list_re($#dthtags, ',', '^(.*)$', 'DTH Tags: \1'), ',',
			list_re($authors, '&', '(^.*)', 'Authors: \1'), '&')
	fi

The problem: no collections are created even though the debug log says the template returned values. Instead I get the following error for all the collections.

Code:

category not added to book.device_collections []

I debugged the problem by copying one book to a new library, preserving structure, and setting the debugging title appropriately. After a few trials I found that the problem is caused by create_collections returning false because nothing is in the collections attributes box. The fix: kobo.driver.py line 3681:

Code:

    @property
    def create_collections(self):
        return (self.manage_collections and self.supports_bookshelves and self.get_pref('create_collections') and
                                (len(self.collections_columns) > 0 or self.use_collections_template))

Do I need to say anything else?

Even that is too much.

You changed/added a lot of stuff, and it is very easy to miss something you don't frequently (if ever) use. For example, I broke separators in template for loops when I added ranges. I discovered this by accident 10 days later when I connected my Libra before my mini-break. My plugboard uses a loop with an '&' separator to rewrite authors from "LN, FN" to "FN LN", and all the author names became "TEMPLATE ERROR".

for all your work.

Just checked the change in and created the pull request. It included the firmware and database version bumps.
