ormsettings.eventHandler
Bernhard Döbler
I'd like to have a CFC handling ORM events setting updated-timestamps
on update and the like.
I keep getting the error:
ormcfcs.ormeventhandler is not a valid ORM event handler.
It must implement interface cfide.orm.IEventHandler
in my Application.cfc I defined
<cfset this.ormsettings.eventHandling = true>
<cfset this.ormsettings.eventHandler="ormcfcs.ormeventhandler">
<cfset this.ormsettings.cfclocation = "/ormcfcs/">
and put the following ormeventhandler.cfc in the ormcfcs folder
<cfcomponent implements="CFIDE.orm.IEventHandler">
<cffunction name="preInsert" access="public" returntype="void"
output="false" hint="I run before this entity is inserted.">
<cfargument name="entity" type="any" />
<!---
Set the date/time properties. This way, we can
keep track of the time at which this object was
created / inserted.
--->
<cfset this.setangelegt_datum( Now() ) />
<cfset this.setgeaendert_datum( Now() ) />
<!--- Return out. --->
<cfreturn />
</cffunction>
<cffunction name="postLoad" access="public" returntype="void"
output="false" hint="I run after this entity is loaded.">
<cfargument name="entity" type="any" />
<!--- Return out. --->
<cfreturn />
</cffunction>
<cffunction name="postDelete" access="public" returntype="void"
output="false" hint="I run after this entity is deleted.">
<cfargument name="entity" type="any" />
<!--- Return out. --->
<cfreturn />
</cffunction>
<cffunction name="preLoad" access="public" returntype="void"
output="false" hint="I run before this entity is loaded.">
<cfargument name="entity" type="any" />
<!--- Return out. --->
<cfreturn />
</cffunction>
<cffunction name="preDelete" access="public" returntype="void"
output="false" hint="I run before this entity is deleted.">
<cfargument name="entity" type="any" />
<!--- Return out. --->
<cfreturn />
</cffunction>
<cffunction name="preUpdate" access="public" returntype="void"
output="false" hint="I run before this entity is updated.">
<cfargument name="entity" type="any" />
<!--- Define the arguments. --->
<cfargument name="oldData" type="struct" required="true" hint="I am
the collection of data held over from the load time." />
<!---
Set the date/time properties. This way, we can
keep track of the most recent time at which this
object was updated.
--->
<cfset this.setgeaendert_datum( Now() ) />
<!---
Return out. NOTE: If this method return TRUE, then
the update is cancelled.
--->
<cfreturn />
</cffunction>
<cffunction name="postUpdate" access="public" returntype="void"
output="false" hint="I run after this entity is updated.">
<cfargument name="entity" type="any" />
<!--- Return out. --->
<cfreturn />
</cffunction>
<cffunction name="postInsert" access="public" returntype="void"
output="false" hint="I run before this entity is inserted.">
<cfargument name="entity" type="any" />
<!--- Return out. --->
<cfreturn />
</cffunction>
</cfcomponent>
It works, when I use the following cfc in script-notation.
component implements="CFIDE.orm.IEventHandler" {
public void function preInsert(any entity){
arguments.entity.setangelegt_datum(now());
arguments.entity.setgeaendert_datum(now());
}
public void function postLoad( any entity){
arguments.entity.setgeaendert_datum(now());
}
public void function postDelete(any entity){
}
public void function preLoad( any entity){
}
public void function preDelete( any entity) {
}
public void function preUpdate( any entity, Struct oldData){
}
public void function postUpdate( any entity){
}
public void function postInsert( any entity){
}
}
Are you using ORM events to modify data preUpdate? Have you used
mappedSuperClass to define event handlers?
Best,
Bernhard

the tag-based version of preUpdate().
