Injecting properties using CRUD framework

[pdhaigh]

Hi,

I am working with the CRUD framework, with everything configured in components.xml.

What I'm trying to add is the concept of last_updated_by - this is just a string that will be equal to #{identity.username}

I can do this fine for a new object:

 <factory name="vacancy" value="#{vacancyDAO.instance}" />
 <fwk:entity-home name="vacancyDAO"
 entity-class="com.example.model.Vacancy"
 new-instance="#{newVacancy}"/>

 <component name="newVacancy" class="com.example.model.Vacancy">
 <property name="last_updated_by">#{identity.username}</property>
 <property name="created_by">#{identity.username}</property>
 </component>

However, without extending entity-home and making a real class for the component, I'm at a bit of a loss of how to insert that #{identity.username} property to an existing object when calling vacancy.update.

Is there a way to do this? (I don't believe you can inject a property direct to a POJO Entity?)

cheers

... you can use Inheritance Aproach, extending EntityHome and overriding update method.

... documentation states:

We can define a personHome component either via configuration:

<framework:entity-home name="personHome" entity-class="eg.Person" />

Or via extension:

@Name("personHome")
public class PersonHome extends EntityHome<Person> {}

there you can

@Override
public String update() {
 setId() ;
 setLastUpdatedBy( someone ) ;
 return super.update() ;
}

Hi,

Thanks for the reply. I knew it was possible extending entityhome, but I was wondering if there was a way to do it via xml configuration?

... then you would be programming in xml instead of java, wrong choice I would say ;)
