Apple

@Override

public void upgrade(EOEditingContext editingContext, ERXMigrationDatabase database) throws Throwable {

ERXJDBCUtilities.executeUpdateScriptFromResourceNamed(database.adaptorChannel(), "DInAdminEOModel1_Postgresql_Upgrade.migration", "DIModelFramework");

}

Something like that?

Is this a "full" Wonder app, extending ERXApplication? If not, you need to initiate the migration:

if (ERXMigrator.shouldMigrateAtStartup())
{
try
{
migrator().migrateToLatest();
}
catch (ERXMigrationFailedException e)
{
// It might be a missing plugin problem
new ERXJDBCConnectionAnalyzer(databaseConnectionDictionary());
throw e;
}
}

Hi all,

I am trying to implement Migrations in an existing Application.

I followed the instructions in this page:

http://webobjects.mdimension.com/hudson/job/Wonder/javadoc/er/extensions/migration/package-summary.html

and this one

http://webobjects.mdimension.com/hudson/job/Wonder/javadoc/er/extensions/migration/ERXMigration.html

I think the steps are:

1. Modify properties file:

# Migrations
er.migration.migrateAtStartup=true
er.migration.createTablesIfNecessary=true
er.migration.modelNames=DInAdminEOModel
er.extensions.migration.ERXMigration.useDatabaseSpecificMigrations=true

DInAdminEOModel.InitialMigrationVersion=1
DInAdminEOModel.MigrationClassPrefix=com.toracom.app.migration.DInAdminEOModel

2. Create class com.toracom.app.migration.DInAdminEOModel1.java

/////// BEGIN CLASS
package com.toracom.app.migration;

import com.webobjects.eoaccess.EOAdaptorChannel;
import com.webobjects.eoaccess.EOModel;
import com.webobjects.eocontrol.EOEditingContext;
import com.webobjects.foundation.NSArray;

import er.extensions.migration.ERXMigration;
import er.extensions.migration.ERXModelVersion;

public class DInAdminEOModel1 extends ERXMigration {
public NSArray<ERXModelVersion> modelDependencies() {
return null;
}

@Override
public void upgrade(EOEditingContext editingContext, EOAdaptorChannel channel, EOModel model) throws Throwable {

}

@Override
public void downgrade(EOEditingContext editingContext, EOAdaptorChannel channel, EOModel model) throws Throwable {
// TODO Auto-generated method stub

}
}

////// END CLASS

3. Create DInAdminEOModel1_Postgresql_Upgrade.migration file

ALTER TABLE parametros ADD COLUMN modulo_cfdivault_habilitado varchar(5);
UDPATE parametros SET modulo_cfdivault_habilitado = 'false';
ALTER TABLE parametros ALTER COLUMN modulo_cfdivault_habilitado SET NOT NULL;

When I run my application never get the SQL code executed. In the Application class I load a Parametros entity but I get the following error

Apr 06 11:38:11 dinadmin[55559] DEBUG NSLog - evaluateExpression: <com.webobjects.jdbcadaptor.PostgresqlExpression: "SELECT DISTINCT t0.directorio_raiz_procesamiento_cfd, t0.email_formato, t0.encoding_archivo_fuente, t0.encoding_escritura_cfd, t0.encoding_escritura_div_sol, t0.encoding_escritura_xml_co, t0.encoding_escritura_xml_impresion, t0.encoding_lectura_jaxb, t0.encoding_obtencion_co, t0.encoding_trans_co, t0.fh, t0.fhc, t0.formato_fecha_dhtmlxgrid, t0.formato_numero_registro_bd, t0.formato_numero_registro_bd_corto, t0.fsh, t0.fshnm, t0.iva, t0.logs_debug, t0.logs_path, t0.logs_stdout, t0.metodo_impresion, t0.modulo_cfdivault_habilitado, t0.moneda_id, t0.nd, t0.ne, t0.nm, t0.nombre_aplicacion, t0.np, t0.ntc, t0.parametros_id, t0.retraso_daemon, t0.rfc_fisica, t0.rfc_moral, t0.sistema_inicializado, t0.url_birt_viewer, t0.version_comprobante FROM parametros t0" withBindings: >

at org.postgresql.jdbc2.AbstractJdbc2Statement.executeWithFlags(AbstractJdbc2Statement.java:336)

Because the modulo_cfdivault_habilitado column does not exist, so the migration's file is never executed.

Am I missing something, maybe a missing Framework?

Thanks in advance.
