Custom configuration class ignored in 3.0 snapshot
I've been using a custom subclass of DefaultConfiguration to customize my database connection.
This works great with 3.0M3. However, today I upgraded to the snapshot build and it seems to be
ignoring the custom configuration class I pass into the
Configuration.initializeSharedConfiguration method. Has the way custom configurations work
changed?
Thanks in advance!

Thanks for the link. I'll use the snapshots provided there from now on.
I just downloaded and tried the latest snapshot from there and I still have the same behavior.

BTW, there is some ambiguity as to the snapshot versions (we
occasionally post to the snapshot Maven repo; and there is also an
independent CI server doing builds on code changes), I recommend using
the jars built by the CI server (choose "Cayenne Aggregated Server
Jar") :

Andrus,
That fixed it. Thanks for the quick response!

I was looking for any clues in the code, nothing concrete... And I
found it. The recent fix to CAY-785 deprecated and stopped calling
"Configuration.getDataSourceFactory()" replacing it with
"Configuration.getDataSourceFactory(String)". So you need to override
the new method. Also I checked in a fix that restores backwards
compatibility. It should be available from the Hudson CI server soon
(build #109 or newer).

Andrus,
I'm not sure exactly how you want the code sample. If you need me to provide a self contained app
I can do that. For now I'll just copy the code from my app so you can take a look at it. I have a
static method that configures my custom DataSourceFactory. The call to DbUtils.openDb succeeds,
but the getDataSourceFactory method in CompanyConfiguration is never called.
public class DbUtils {
private static DataContext globalContext;
private static DataContext estimateContext;
private static DataContext roomContext;
private static DataContext assemblyContext;
private static DataContext partsContext;
public static void openDb(String pathToDb) throws Exception {
try {
CompanyDataSourceFactory.setDbPath(pathToDb);
Configuration.initializeSharedConfiguration(CompanyConfiguration.class);
Configuration config = Configuration.getSharedConfiguration();
DataDomain domain = config.getDomain();
globalContext = DataContext.createDataContext(domain.getName());
estimateContext = DataContext.createDataContext(domain.getName());
roomContext = DataContext.createDataContext(domain.getName());
assemblyContext = DataContext.createDataContext(domain.getName());
partsContext = DataContext.createDataContext(domain.getName());
} catch (Exception e) {
throw new Exception("Unable to initialize database!", e);
}
}
}
public class CompanyConfiguration extends DefaultConfiguration {
private static CompanyDataSourceFactory factory = new CompanyDataSourceFactory();
@Override
public DataSourceFactory getDataSourceFactory() {
return factory;
}
}
public class CompanyDataSourceFactory implements DataSourceFactory {
private static DataSource ds = null;
private static String dbPath = "Companies/db";
public static void setDbPath(String val) {
dbPath = val;
}
@Override
public DataSource getDataSource(String arg0) throws Exception {
if(dbPath.startsWith("server")) {
// server:host
ClientDataSource40 tmpDS = new ClientDataSource40();
String[] sArray = dbPath.split(":");
tmpDS.setServerName(sArray[1]);
tmpDS.setDatabaseName("db");
tmpDS.setUser("user");
tmpDS.setPassword("pass");
ds = tmpDS;
} else {
EmbeddedDataSource40 tmpDS = new EmbeddedDataSource40();
tmpDS.setDatabaseName(dbPath);
tmpDS.setUser("user");
tmpDS.setPassword("db");
ds = tmpDS;
}
return ds;
}
@Override
public void initializeWithParentConfiguration(Configuration arg0) {
}
}
Hopefully that's enough. If not let me know what I should provide.
Thanks for your help!

Strange. That should still work the same. The only change to
Configuration since M3 was related to the DataSourceFactory handling
(CAY-785)... Do you have a code example that demonstrates the problem?
Thanks,

Datamodel advice
Posted by Fredrik Liden <fl...@translate.com>.
Hi, I'm wondering what is the best way to implement this structure in
Cayenne:
Let's say there is a list of users assigned to a client:
m:n between USER (userid) and CLIENT (clientid) and between CLIENT_USER
(userid,clientid) is the flattened table.
Now from that list of users in CLIENT_USER I want to one and assign to
say a certain languages. I believe the correct datamodel would be:
m:n between CLIENT_USER (userid,clientid) and LANGUAGE (languageid)
where ASSIGNMENT (userid,clientid,languageid) would be the between
(flattened) table.
Is it possible to have a flattened table (ASSIGNMENT) based on another
flattened table (CLIENT_USER)? Or should I unflatten CLIENT_USER and add
a cayenne generated id so it would be
CLIENT_USER(client_userid,userid,clientid) and ASSIGNEMENT
(client_userid,languaged) would be flattened.
I find that I'm often coming back to this situation so just wondering if
anyone has any suggestions.
Thanks,
Fredrik
