How can I get the description of a table field, or field from
CayenneObject
Hi all, I was quite new with Cayenne, how can I do this :
Book extends _Book
public static final String DESCRIPTION_PROPERTY = "description";
public static final String ID_BOOK_PROPERTY = "idBook";
public static final String LEVEL_PROPERTY = "level";
public static final String PATH_PROPERTY = "path";
public static final String STATUS_PROPERTY = "status";
public static final String TITLE_PROPERTY = "title";
....
How can I get the information of field (title, "title" , String ) which
inside CayenneObject , or I have to write the inspector by my own? ( There
some bean inspector library but I think Cayenne done that already, and other
hack will be ugly )...
-----------------------------
*Further :*
I'm intergrating Jasper with Cayenne and want to provide Jasper Designer
IReport a DataProvider , which in turn list the Field of the Table or Entity
to Roll through the Database ...
I was quite new with Cayenne so I can't find anywhere a way to get the field
description, name, title and so... from a CayenneObject like Book (which
generated by Cayenne Modeler ) , It's not too hard to type the names
manually but I still think there is a way to get this out by Cayenne.
Did anyone walk this line before, really appreciate the helping!

Also in runtime, you have access to ObjEntity object that contains all the entity ORM metadata.
Book myBook = ...
ObjEntity e = context.getEntityResolver().lookupObjEntity(myBook);

You mean the page in the documentation which I linked you to?

I don't understand. The ant task I pointed you at does exactly that.

Thank a lot Aristedes and Andrus
You both point me very good directions which I don't know before. Cheer,
this should really be written somewhere in the documentation!
@Aristedes :
Now assume we can use cgen Template to generate some other Class to suite
our need (Japser intergration), are you and your team do that way or
automaticly sync the two dataProvider and ObjEntity ,
In our case we has a lot (~500 +) of Table , ObjEntity, and Report(s) for
them, so each time we save XML, we want to generate all other things to make
them perfectly match...
Do you have any advice for the case, deeply appriciate that!

There is a little ant task called cgen which creates the getters and setters for you.

Yes. We use JasperReports and wrote our own data provider to do just that. It isn't too hard to glue it all together.
