circulation: possibility to check-out in-transit items

[BadrAly]

• FIX Fixes Check-out of an item "in transit" #230: allows checkout of in-transit items.

Signed-off-by: Aly Badr [email protected]

This two scenarios works:

• checkout out an item (having no requests) with loan_status= ITEM_IN_TRANSIT_TO_HOUSE to any patron.

• checkout out an item with loan_status= ITEM_IN_TRANSIT_FOR_PICKUP to any requested patron from any checkout library.

2 problems observed

Use case 1

1. The item of Lib A is requested by Simonetta, with pick-up in Lib B
2. The item is checked-out in Lib C for Simonetta, without action "receive"
3. Check-out is allowed, but the request persist

Problem: the request of Simonetta should be satisfied at the check-out.

Use case 2

1. The item of Lib A is requested by Simonetta, with pick-up in Lib B
2. The item is checked-out in Lib C for Alain, without action "receive"
3. Check-out is allowed

Problem: check-out should be allowed only for the first patron in the request queue (for now). Later, the librarian will have the option to override the limit.

This meen that the second scenario described in this pull request is not correct (not conform to #230):

checkout out an item with loan_status= ITEM_IN_TRANSIT_FOR_PICKUP to any requested patron from any checkout library
