[baseten-users] BaseTen 1.6.1 just released

[Jianhua Meng]

Thanks Tuukka for the update!

I'm seeing an error on my console when my app launches. It made a  
connection with the database, the app appears stuck after running the  
following code:
- (void)primeEntities
{
	NSError *error = nil;
	NSDictionary *allEntities = [[self databaseContext]  
entitiesBySchemaAndName:NO error:&error];
	if (error == nil) {
		NSDictionary *entities = [allEntities objectForKey:[QCXManagedObject  
schemaName]];
		NSArray *entityNames = [entities allKeys];
		for (NSString *entityName in entityNames) {
			BXEntityDescription *entityDesc = [entities objectForKey:entityName];
			Class entityClass = NSClassFromString([NSString  
stringWithFormat:@"QCX%@", entityName]);
			[entityDesc setDatabaseObjectClass:entityClass];
		}
	}
}

This code has worked fine on my own machine and won't work on other  
machines I tried. The difference between mine and others is that the I  
have the latest schema whereas the other machines don't have the  
latest schema. Would the difference explain for this particular error?

What does "doesn't have relationship capability" mean? What would be  
likely cause?



Another question: suppose I have two database contexts, contextA and  
contextB and the both contain the same underlying Person object.  
Suppose I changed the Person object via contextB. What's the best way  
to refresh the same object in contextA? In general what is the  
mechanism in baseten to refresh the contents of contextA? Is the  
synchronization automatic?  At some point, I'll need to use multiple  
database contexts to manage complex operations. Having a good  
understanding of how multiple contexts work will help my design.

Thanks for your tips in advance.

I have question which you could answer, I hope.
