Hi!
I have a method like the one below, where I want to send in a model
with a different connection dictionary and execute a fetch using
the alternate model database. I'm running the below, setting the
new default group, then setting it back, however the results always
appear to come from the regular default model group, not the new
model group I'm setting below. Does anyone see something I'm missing?
Thanks,
Scott
public static NSArray
executeSQLForModelWithResults(EOEditingContext ec, String sql,
EOModel model) {
// Save defaultGroup
EOModelGroup defaultGroup = EOModelGroup.defaultGroup();
defaultGroup.models().containsObject(model) == false, right? But it
contains a different instance of EOModel that has the same entities?
defaultGroup contains model with same name, but not the same
connection dictionary.
// Create new group
EOModelGroup newGroup = new EOModelGroup();
newGroup.addModel(model);
EOModelGroup.setDefaultGroup(newGroup);
Probably not a good idea to mess with this... Things run deeper here.
Hmm
// perform fetch
NSArray results = EOUtilities.rawRowsForSQL(ec, "modelname", sql,
null);
ec's are model group / EOF stack specific. You can not pass in an
EC like that. You need a whole new EOF stack with a new database,
database context, and object store co-ordinator.
What is a safe way to create a new EOF stack?
Chuck
// reset group to default
EOModelGroup.setDefaultGroup(defaultGroup);
return results;
}
