Hi, There's been some discussion in the comments for bug 10120 [1] about the notion of storing whether an loan is hourly or not in the loan record itself. I'd like to expand this discussion to include the notion of storing a copy of all relevant circ policy in the loan. In particular, I'm thinking of - fine - finedays - chargeperiod - issuelength - lengthunit - renewalsallowed - renewalperiod - overduefinescap Doing this would help solve the immediate problem for bug 10120 of allowing us to (cheaply) determine if a loan is hourly and therefore should always have its fines recalculated upon checkin, but it would have some other advantages: - it would make it easier to decide if a given due date display should include the due time or not - it allows staff to change circ policies (and in particular, fine policies) without having to worry about affecting current loans. On the other hand, perhaps there are times when some libraries *do* want to make a policy change affect current loans -- I'd appreciate hearing about real life examples if this is the case. Another possibility would be simply storing a reference to the applicable policy. If we do it that way, we could give issuingrules an opaque primary key, but I think we'd then also have to have to teach that table how to keep track of old policy rows as well. Thoughts?
