| Thanks Chuck, Paul and Mike for your help
The principal problem was that Migrations functionality is called automatically after my own code that loads some info from de data base, so if the migration has changes in a table that is considered in my code the app crashes before the migration occurs.
The solution is to add the Chuck's code before everything else in the constructor of my Application class.
if (ERXMigrator.shouldMigrateAtStartup()) { try { migrator().migrateToLatest(); } catch (ERXMigrationFailedException e) { // It might be a missing plugin problem new ERXJDBCConnectionAnalyzer(databaseConnectionDictionary()); throw e; } }

It should have a row in there with your EOModel name in it; set the version back to null.

For some reason the code inside the upgrade class is never called.
I think I should mistyped something. I am checking now.

You will need to call the external sql script from inside of your Migration.java file.
@Override public void upgrade(EOEditingContext editingContext, ERXMigrationDatabase database) throws Throwable { ERXJDBCUtilities.executeUpdateScriptFromResourceNamed(database.adaptorChannel(), "DInAdminEOModel1_Postgresql_Upgrade.migration", "DIModelFramework"); }
Something like that?

I am trying to implement Migrations in an existing Application.
I followed the instructions in this page:
and this one
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: > Apr 06 11:38:11 dinadmin[55559] DEBUG NSLog - === Rollback Internal Transaction ERROR: column t0.modulo_cfdivault_habilitado does not existat org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:1608) at org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:1343) at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:194) at org.postgresql.jdbc2.AbstractJdbc2Statement.execute(AbstractJdbc2Statement.java:451) 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.
