------------------------------------
Summary: cgen: Generate properties for PK
Key: CAY-2478
URL: https://issues.apache.org/jira/browse/CAY-2478
Project: Cayenne
Issue Type: Improvement
Components: Modeler, Non-GUI Tools
Reporter: Nikita Timofeev
Fix For: 4.1.M3
To use PK in query (in where or order by clause) you need to write custom
expressions and that is most likely ugly (something like
{{ExpressionFactory.matchDbExp("db:" + Artist.ARTIST_ID_PK_COLUMN, 1)}})
So we may just use Cayenne Property API and generate these properties in cgen
tools.
A few things to keep in mind:
* PK can be compound, in that case there should be several properties
* PK can be already mapped on ObjAttribute, in that case we shouldn't generate
anything
* PK property naming shouldn't clash with other properties
* this feature should be optional (or not?)
