Estos días he estado trasteando con vufind ([1] y [2]).
Mostrar el enlace hacia Holds
En algunas bibliotecas que también tienen vufind y su catálogo es Innovative Millenium había visto que mostraban la posibilidad de colocar un enlace para reservar ejemplares directamente. Sin embargo en mi instalación de vufind no parecía funcionar.
Investigando un poco en la wiki de vufind descubrí que el fichero que me estaba “fastidiando” era el view-holdings.tpl y más en concreto estas líneas:
{foreach from=$holding item=row} {if $row.barcode != ""} |
Mis registros no tenían un valor de barcode asignado, por lo cual esa parte del código no se ejecutaba.
¿Cómo lo averigué? Colocando un print_r de la variable $row en smarty (cómo hacer print_r de arrays en smarty templates). Mi código de view-holdings.tpl ha quedado ahora asi:
{foreach from=$holding item=row} <em> Edit view-holdings.tpl by MiguelMartin</em><br /> {$row|@print_r} <!-- comento esta linea y añado la siguiente --> <!--if $row.barcode != ""--> {if $row.id != ""} |
Como todos mis registros sí tienen ID, el código se ejecuta y se muestra el link.
Que viva el open source! 
(Para saber cómo configurar la conexión entre vufind y tu software de catálogo puedes consultar éste link)
Hacer que funcione el enlace a Holds usando Innovative
El link que se genera con lo anterior es del tipo
http://yourvufindserver.com/vufind/Record/.b10002030/Hold
Si usamos el driver de Innovative que viene por defecto (la pareja de archivos Innovative.ini y Innovative.php) obtendremos un error de PEAR que dice algo asi:
Cannot Process Place Hold - ILS Not Supported |
Este error viene de $VUFIND_HOME/web/services/Record/Hold.php.
Para solucionarlo cambiad vuestro Innovative.ini por algo del tipo (ojo, cambiad la ‘url’ de la sección [Catalog] y de [PATRONAPI] para que apunte a la url de vuestro catálogo):
[Catalog] url = http://iii.server.org ; The following is a set of fields to look up for ; Change them to match your HTML [OPAC] location_column = "Location" call_no_column = "Call No" status_column = "Status" reserves_column = "Location" reserves_key_name = "res" status_avail = "AVAILABLE" status_due = "DUE " [CONFIG] ; "bib" or "item" level holds holdtype = "bib" [PATRONAPI] ; Enable III Patron API usage for patron authentication ; and profile information. enabled = "true" url = http://iii.server.org:4500/PATRONAPI/ |
Y vuestro Innovative.php por:
