https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=12133 --- Comment #38 from Emmi Takkinen <emmi.takkinen@koha-suomi.fi> --- Okay, "Child cannot be guarantor" error happens because $patron_category needs "can_be_guarantee" value set as 0. "Invalid value passed, borrowers.updated_on=SCALAR(0x558a5143c3d8) expected type is datetime#" happens because calling store for $child2 a.k.a modding patron sends "updated_on" as a scalar. This can be solved with calling discard_changes() after first time calling $child2->store succesfully. -- You are receiving this mail because: You are watching all bug changes.
