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

1101 I don't know what this does, because I don't understand how reserve
1102 constraints work. I think the idea is that you reserve a particular
1103 biblio, and the constraint allows you to restrict it to a given
1104 biblioitem (e.g., if you want to borrow the audio book edition of "The
1105 Prophet", rather than the first available publication).

1108 C<@results> is an array of references-to-hash whose keys are mostly
1109 fields from the reserves table of the Koha database, plus
