Those sound like good ideas to me! We could add a system pref for "follow rules from the time of checkout" vs "follow current rules". I think the opaque key isn't a bad idea either. Rules could be set to 'active' or 'inactive' so that previous checkouts could follow these inactive rules but new checkouts would ignore them.

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?
