play framework: 1.2.3

Hi,

I am trying to purge my database by using play’s fixtures. However, I run into some problems trying that.

First, Fixtures.deleteDatabase() deletes the whole database and play does not recreate it on another test (also I haven’t found nothing to do so.

Second, trying to deleteAllModules() I get an exception for any model play is trying to delete:

java.sql.SQLException: Lock wait timeout exceeded; try restarting

These models have been created during the test using the normal Model.save(). I suppose that – once again – transactions come into my way somehow. However, looking at the database, all models get persisted.

@After
public void tearDown() throws InterruptedException, ExecutionException {
    new Job() {
        @Override
        public void doJob() throws Exception {
            Logger.debug("[SetupUtils.createClearDBJob().new Job() {...}] Deleting database");
            Fixtures.deleteAllModels();
            //              Fixtures.delete()
            //              Fixtures.deleteDatabase();
        }
    }.now().get();
}

    You can try to set the create/delete operaton in the Bootstrap, and to check if Play! is running in test mode or production mode.

    @OnApplicationStart
public class Bootstrap extends Job {

  public void doJob() {
    if (Play.mode == Play.Mode.DEV) {
        DropboxFolder.deleteAll(); // delete 
        Fixtures.load("samples_data.yml"); // recreate 
    }
  }
}
