Prototypes also make the process of modeling 10x faster, btw ... Even if you don't switch databases at all, I recommend switching entirely to them. The workflow in Entity Modeler is optimized for using prototypes.

We had this in Wonder for ages now... for us the lookup is:

EOJDBCPostgresqlPrototypes
EOJDBCPrototypes
EOPrototypes

At startup we combine a prototype entity with all the attributes, first write wins, so you can keep common ones in EOPrototypes and only refine in EOJDBCPostgresqlPrototypes. Then all prototypes are applied to the model. With 5.4 I have no idea. I assume it's similar.

Cheers, Anjo

Hello;

I see the following which looks good, but doesn't really explain the mechanics -- does anybody know how this has changed?

Radar #5084084
Enhance EOF prototyping support

Description:
Enhance EOModel prototyping support to make it recognize the Database Management System used just like it does with the plugin support.


Workaround:
This has been fixed in WebObjects 5.4.


I presume it is a bit more clever than just looking for an entity called EOJDBCAdaptorPrototypes and will somehow look for an entity with the JDBC plugin's name in it or something?


cheers
