Much easier to use:
<something> => extraRestrictingQualifier = {
"band" = "session.user.band";
} [ERDDelayedExtraQualifierAssignment]
QueryPage:
public EODataSource queryDataSource() {
EODataSource ds = null;
if(ds == null) {
ds = super.queryDataSource();
}
if (ds != null && (ds instanceof EODatabaseDataSource)) {
EOFetchSpecification fs =
((EODatabaseDataSource)ds).fetchSpecification();
EOQualifier q = fs.qualifier();
EOQualifier extraQualifier =
(EOQualifier)d2wContext().valueForKey("extraRestrictingQualifier");
if(q != null && extraQualifier != null) {
q = new EOAndQualifier(new NSArray(new Object[] {q,
extraQualifier}));
} else if(extraQualifier != null) {
q = extraQualifier;
}
fs.setQualifier(q);
fs.setUsesDistinct(true);
}
return ds;
}
