Here's how I implemented it (it's actually quite simple):
In Session.java:
public ERXObjectStoreCoordinator defaultObjectStoreCoordinator() {
return defaultObjectStoreCoordinator;
}
public void setDefaultObjectStoreCoordinator(ERXObjectStoreCoordinator
defaultObjectStoreCoordinator) {

I agree, cross model relationships with different database connections
shouldn't be used in real applications : eof bugs aside, there's one major
problem : it's not transactionnal.
Larry setup is interesting though, looks like the new old wo 4.5.1 :), the
optimistic locking will work for sure !

those are definitely all problems i am currently facing. it's fine if
everything is sequestered off into it own model, but relationships between them
are not going to happen unless you manually manage what relationship's object
gets pulled into what context. it's not manageable for any real-wo
Speaking of which, I wonder what migrations do for cross db fks? Does it blow
up trying to form a constraint? I'll have to look sometime.
Which raises another interesting issue. Do you create cross model relationships
Larry? I could see that causing problems. For example, create an EO in common
Let me be more clear.
It is possible to run migrations automatically but the different databases
(whose connection dictionary is only known inside a session) will not all be
automatically updated.
I have migrations turned on and automatically connecting to (and updating) an
empty database that
it is. this is what i'm basically doing to on a per session basis

Not automatically. Migrations happen during the application startup and at that
point, they have default connection dictionary information. I do use migrations
but that just migrates the common databases and an empty stub database (that
uses the default connection dictionary) on the main db ser
IIRC, it is not handled.

Out of curiosity, do you happen to know if it's possible to run migrations
against multiple data stores like you have Larry?

I do have an app with a different database connection per session. This does
appear to be relatively uncharted territory, but it has been working in
production for a while and it has been working pretty well. This is not a high
volume transactional application.
I use two models in this setup. O
Paul,
Maybe this project can be helpful. I created it following Chuck's advice. It's
very experimental, but works. Sorry for the lack of comments in the source code.

I have never done this, but I think it can be done. You will need to create
new EOModelGroups, load/copy the models from the default group, set the
connection information, and create a new EOObjectStoreCoordinator from that new
model group. You need to be very careful in your code (and in any

Although some of the information there (providing multiple database channels)
is wrong.
databaseContext
yes, look at chuck's book for fiddling with the connection dictionary

Hi List,
is there any way to have different database connections per session? I need
this in an application for giving the user the ability to change between
several different copies of the database to work on.
I always tried to copy EOModels and so on, read some mails from the list but
not re
