43 C4::Reserves - Koha functions for dealing with reservation.
51 this modules provides somes functions to deal with reservations.
53 Reserves are stored in reserves table.
54 The following columns contains important values :
55 - priority >0 : then the reserve is at 1st stage, and not yet affected to any item.
56 =0 : then the reserve is being dealed
57 - found : NULL : means the patron requested the 1st available, and we haven't choosen the item
58 W(aiting) : the reserve has an itemnumber affected, and is on the way
59 F(inished) : the reserve has been completed, and is done
60 - itemnumber : empty : the reserve is still unaffected to an item
61 filled: the reserve is attached to an item
62 The complete workflow is :
63 ==== 1st use case ====
64 patron request a document, 1st available : P >0, F=NULL, I=NULL
65 a library having it run "transfertodo", and clic on the list
66 if there is no transfer to do, the reserve waiting
67 patron can pick it up P =0, F=W, I=filled
68 if there is a transfer to do, write in branchtransfer P =0, F=NULL, I=filled
69 The pickup library recieve the book, it check in P =0, F=W, I=filled
70 The patron borrow the book P =0, F=F, I=filled
72 ==== 2nd use case ====
73 patron requests a document, a given item,
74 If pickup is holding branch P =0, F=W, I=filled
75 If transfer needed, write in branchtransfer P =0, F=NULL, I=filled
76 The pickup library recieve the book, it checks it in P =0, F=W, I=filled
77 The patron borrow the book P =0, F=F, I=filled

999 Now just gets an array of reserves in the rank order and updates them with
1000 the array index (+1 as array starts from 0)
1001 and if $rank is supplied will splice item from the array and splice it back in again

1091 I don't know what this does, because I don't understand how reserve
1092 constraints work. I think the idea is that you reserve a particular
1093 biblio, and the constraint allows you to restrict it to a given
1094 biblioitem (e.g., if you want to borrow the audio book edition of "The
1095 Prophet", rather than the first available publication).

1098 C<@results> is an array of references-to-hash whose keys are mostly
1099 fields from the reserves table of the Koha database, plus
1100 C<biblioitemnumber>.
