|
|
|
use C4::Suggestions;
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
=over 4
|
|
|
|
The functions in this module deal with the suggestions in OPAC and in librarian interface
|
|
|
|
A suggestion is done in the OPAC. It has the status "ASKED"
|
|
|
|
When a librarian manages the suggestion, he can set the status to "REJECTED" or "ACCEPTED".
|
|
|
|
When the book is ordered, the suggestion status becomes "ORDERED"
|
|
|
|
When a book is ordered and arrived in the library, the status becomes "AVAILABLE"
|
|
|
|
All suggestions of a borrower can be seen by the borrower itself.
|
|
Suggestions done by other borrowers can be seen when not "AVAILABLE"
