http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=4530 --- Comment #23 from Gaetan Boisson <gaetan.boisson@biblibre.com> --- I think we really need 0 and NULL to be treated differently. It is important for instance to define that a type of document cannot be issued to a certain category of patrons, without falling back on a more generic rule that would allow it. Sometimes we also want to define that 0 books of that type can be issued to a patron category, with a loan period of X days : if we force the loan on an exceptional basis, the length of the loan will already be defined. Here is my test plan so far: i have defined 8 rules, matching the 8 possibilities. For every rule i put the same value in each field: 8 for same library, same patron type, same item type 7 for same library, same patron type, all item types 6 for same library, all patron types, same item type 5 for same library, all patron types, all item types 4 for all libraries, same patron type, same item type 3 for all libraries, same patron type, all item types 2 for all libraries, all patron types, same item type 1 for all libraries, all patron types, all item types the i tweak to put NULL (or 0 at the moment) at different places, loan some books and see what happens. So far one thing that turned out not to work out was the number of renewals : it falls straight back to rule 3, and if i void rule 3 it falls back to rule 1, ignoring rule 2. There are a lot of possibilities to test and i am not done yet... -- You are receiving this mail because: You are the QA Contact for the bug. You are watching all bug changes.
