I would like to store the date of last access to some table entries.
I tried to use the onLoad event to update a lastAccess property. This seemed to work for the view, the lastAccess value was updated. But the changes were never written in the DB.
Every time I accessed the list view, the old value was reloaded from the DB. Can I change properties in the onLoad closure?
I used following domain class:
class Foo {
String name
Date dateCreated; Date lastUpdated; Date lastAccess;
static constraints = { name( nullable:false, unique:true ); lastUpdated(); lastAccess( nullable:true ); }
def beforeInsert = { lastAccess = new Date(); }
def onLoad = { println 'this: ' + this;
def aktDate = new Date(); println 'current time: ' + aktDate; println 'last access time: ' + lastAccess + ' always nearly dateCreated: ' + dateCreated; println 'last upadte: ' + lastUpdated + ' remains unaltered too'; lastAccess = aktDate; println 'new last access: ' + lastAccess; } }
which gave me for the first access by the list view:
this: Foo : 1 current time: Mon Dec 31 02:01:48 CET 2007 last access time: 2007-12-31 02:01:44.878 always nearly dateCreated: 2007-12-31 02:01:44.898 last upadte: 2007-12-31 02:01:44.898 remains unaltered too new last access: Mon Dec 31 02:01:48 CET 2007 2007-12-31 02:01:51.129:/test:INFO: GSP servlet initialized
and for the second access:
this: Foo : 1 current time: Mon Dec 31 02:06:25 CET 2007 last access time: 2007-12-31 02:01:44.878 always nearly dateCreated: 2007-12-31 02:01:44.898 last upadte: 2007-12-31 02:01:44.898 remains unaltered too new last access: Mon Dec 31 02:06:25 CET 2007
and so on:
this: Foo : 1 current time: Mon Dec 31 02:12:37 CET 2007 last access time: 2007-12-31 02:01:44.878 always nearly dateCreated: 2007-12-31 02:01:44.898 last upadte: 2007-12-31 02:01:44.898 remains unaltered too new last access: Mon Dec 31 02:12:37 CET 2007
By the way, there was a similar issue posted some time ago: http://www.nabble.com/Domain-onLoad-event-doesn%27t-appear-to-work-to13714486.html#a13714486 http://www.nabble.com/Domain-onLoad-event-doesn%27t-appear-to-work-to13714486.html#a13714486
