Hi Joe,
AFAIK, if you just define properties below for each model using the
syntax <modelname>.URL, <modelname>.DBUser, etc., all the models and
their entities will be automatically loaded at startup by Wonder which
checks for such properties at startup.
In your Application constructor, after super(), all the models and
entities will have been loaded by Wonder, so you can iterate thru
models and/or entities and do what you like with them, for
example ......
// Make demography eomodel readonly
boolean demographyIsReadOnly =
ERXProperties
.booleanForKeyWithDefault("demography.isReadOnlyEntities", false);
if (demographyIsReadOnly) {
EOModel demography =
EOModelGroup.defaultGroup().modelNamed("demography");
for (java.util.Enumeration demographyEntityEnumerator =
demography.entities().objectEnumerator(); demographyEntityEnumerator
.hasMoreElements();) {
EOEntity entity = (EOEntity)
demographyEntityEnumerator.nextElement();
entity.setReadOnly(true);
}
}

Hi Joe,
Not sure if this is what you are looking for .... here is an
example of
entries in Properties for access to different databases:
<snip>
#########################################################################
# ERExtensions - ERXModelGroup properties
#########################################################################
er.extensions.ERXModelGroup.prototypeModelNames=WKPrototypes
cheetah.URL = jdbc:mysql://host1/cheetah?capitalizeTypenames=true
cheetah.DBUser = @@cheetah.dbuser@@

cheetah.DBJDBCInfo =
demography.URL = jdbc:mysql://host2/demography?
capitalizeTypenames=true

demography.DBPassword = @@demography.dbpassword@@
demography.DBDriver =

demography.DBJDBCInfo =

IIRC, ERXModelGroup is where a lot of model startup entity loading
munging
happens, so examining the source there can indicate what is
happening, how
it works, and what Properties entries affect what.
I'll look into the code. Never looked inside Wonder source and was
hoping for examples on how to use it. So, there isn't posted anyway
examples on using ERXModelGroup and loading models into an app within
Application? Again, I've been limited to the stuff that WO just gives
you to date, which is all automatic. My understanding currently ends
there.
HTH,
Kieran

That would need to be an ER Model I take it. Again, do you happen to
have a snippet of code taking multiple entity modeler defined
models,
overriding those settings, etc, and then having a joined model
group..
or should this not be in a model group. I'm confused as to how
this is
all done w/ Wonder as I've also been trying to use ModelConnector
and
other PracticalWO Frameworks solutions to the same.

Ok. I've banged my head on this one a lot. ConfigurationManager

dbConnectURLGLOBAL=jdbc:postgresql://localhost/meetings
That can also be set on a per model base.
