Hi,

I've seen this topic and I find it cool:
http://drc.ideablade.com/xwiki/bin/view/Documentation/many-models-per-manager

Example, I have two Models:

Model A
Customer

Model B
Employee

Then using the approach given on the post, I'll use EntityManager to query:

so.. 

EntityManager context = new EntityManager();
var query1 = context.GetQuery<Customer>().Execute();
var query2 = context.GetQuery<Employee>().Execute();

the question would be, how about if Model A connects to DB A and Model B connects to DB B, how do we handle that?

Thanks,
Von

Von,
 
There's no special handling if you want one EntityManager with multiple models from different datasources.
 
You simply create your models pointing to their respective datasources and in the model properties assign the mutual EntityManager name:
 
 
The only restriction is that you would not be able to have entities from different models, but with the same names. (i.e. Employee and Employee)
 
I'm attaching a simple solution showing one EM with multiple models from different datasources: uploads/892/T11806.zip
 
Regards,
   Silvio.

Hi Silvio,

How about the IDataSourceKeyResolver, is it still possible here in different models?

Thanks,
Von
