Problem checking out after recent update

Ahhh. Version updating seems to be a red herring. The real bulk imported list had blank circulation types and I generated these later in circulation types, but each item still had a blank unless edited individually only then did it assumed the first one by default. This caused the unfriendly blank page, an error message would have been nicer.

So how to edit or remove a circulation type name? The only option appears to be changing the duration. I now have a set of unusable types as I misapprehended their use.

You will have to directly hack the database or else delete everything and reload correctly. The type field is important for checkout and hold: it contains the loan and hold period. The *typical* use is to limit DVDs to a 1 week loan period as opposed to books having a 3 week loan period, since one can watch a movie in one evening, but reading a book (eg “War and Peace”) will take alot longer.

I thought that it should have generated an error when uploading with bad type field values. Something I need to look into sometime.

When you say ‘delete everything’ do you mean the whole collection, or remove the plug in or something in between? I tried deleting the collection but the circulation types remained.

I meant clearing out the collection. To clear out the types you will need to directly access the MySQL database. You will need to have a set of types defined before reloading the collection, and the collection needs to have the proper types referenced in order for the hold and checkout periods to work properly. The types provide the loan period, for example “book” might have a 3 week (21 day) loan period and “dvd” might have a 1 week (7 day) loan period.

OK thanks for clarifying.
Actually I have found that if a bulk imported list contains a type not previously defined, that type is automatically created when an item of that type is first checked out, which is kind of useful.
