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

1098 I don't know what this does, because I don't understand how reserve
1099 constraints work. I think the idea is that you reserve a particular
1100 biblio, and the constraint allows you to restrict it to a given
1101 biblioitem (e.g., if you want to borrow the audio book edition of "The
1102 Prophet", rather than the first available publication).

1106 fields from the reserves table of the Koha database, plus
