[Sculpture 3] Model transformation

[Alessio D'Innocenti]

Hi all, 

I'm not sure I'm in the right place for that, but I would like to know if there is a way to customize model transformation in a way similar to template overriding (@ChainOverride).

I need to remove unuseful (for my project) stuff from DomainEvent and CommandEvent such as "occurred" and "recorded" properties (maybe overriding modifyDomainEvent and modifyCommandEvent). I tried throght AOP too, but unsuccessfully.

Thank for your work and for your help

You need separate project (let's call it YOUR-GEN-PROJECT) - if you need I can send you 'template'.

Than in src/main/java/generator/SpecialCases.xtend you can have for example something like this:

It's using simple naming convention - name have to be "OriginalTmpl" + "Override" and you need @ChainOverride annotation.

___________________________________________________________________

package generator

import org.sculptor.generator.util.CamelCaseConverter

import org.sculptor.generator.chain.ChainOverride

import org.sculptor.generator.template.jpa.JPATmpl

import org.sculptor.generator.template.service.ServiceTmpl

import sculptormetamodel.Application

import sculptormetamodel.Service

@ChainOverride

class JPATmplOverride extends JPATmpl {

override String persistenceUnitAnnotatedClasses(Application it, String unitName) {

next.persistenceUnitAnnotatedClasses(it, unitName) + '''

<!-- smartclient classes -->

<class>sk.f4s.albiq.process.domain.AlbiqProcess</class>

<class>sk.f4s.albiq.service.domain.Users</class>

'''

}

}

@ChainOverride

class ServiceTmplOverride extends ServiceTmpl {

  override String springServiceAnnotation(Service service) {

'''@org.springframework.security.access.annotation.Secured("ROLE_�CamelCaseConverter::camelCaseToUnderscore(service.name).toUpperCase()�")

'''

+ next.springServiceAnnotation(service)

}

}

And in service project you need to setup generator plugin like:

<plugin>

<groupId>org.sculptorgenerator</groupId>

<artifactId>sculptor-maven-plugin</artifactId>

<version>${sculptor.version}</version>

<executions>

<execution>

<id>cleanup</id>

<goals>

<goal>clean</goal>

</goals>

</execution>

<execution>

<id>code-generation</id>

<goals><goal>generate</goal></goals>

</execution>

</executions>

<configuration>

<verbose>true</verbose>

</configuration>

<dependencies>

<dependency>

<groupId>COM.YOUR.COMPANY</groupId>

<artifactId>YOUR-GEN-PROJECT</artifactId>

<version>1.0.0-SNAPSHOT</version>

</dependency>

</dependencies>

</plugin>

Thank you for you quick replay and for your time, of course.
That's ok. I already saw how to do this in mongo-db example from github repository.
No problem in overriding templates, I tested following the example and it works pretty well.

However I need to do something like this:

import sculptor
metamodel; around transformation::Transformation::modifyDomainEvent(DomainEvent event)  :
    null;

My purpose is to add no other property other than provided ones on domain event (and command event as well).

Thanks

Transformation is not @ChainOverridable. I will check tomorrow why. This mean for now it's not possible.

Thanks

[Alessio D'Innocenti]

Thank you again.

Is there a workaround to achieve the same result at moment?

[Pavel Tavoda]

Sorry I was busy last days. Only option is to download and compile yourself with @ChainOverridable, or wait some days. I will do it today.

It's ok.Thank you for the reply.

I think I'll wait for that :)

I tried it but to no avail :-(
