Hi to all,
I'm evaluation Apache Chayenne in order to insert it into some existing applications.
I'd like to ask a suggestion if the use of Chayenne that I'm intending could be correct.
In this example I'd like to integrate Cayenne for manage user of a Java application.
At the moment, in this application, when I'd like to insert a new user, I run a simple code like:
private myUserClass user = new myUserClass ();
user.setName("Name");
user.setSurname("Surname");
After that I compute same operation on this user, for example:
if testUserValidation(user)
{
user.insertToDB()
}
else
{
// Nothing to do user it’s not inserted into DB.
}
So the user is inserted into DB, if and only if it pass the validation.
Now I'd like to introduce Cayenne so I’ve create my User class and mapped it to a DB using CayenneModeler and all seems to work, my question is how can I complete the task above, in particular how to initializate an empty object without inserting it into DB. In getting started guide I found only this example:
Artist picasso = context.newObject(Artist.class);
This create a persist object, I'd like to initialize a non persisting object and make it persisting only after some validation or similar conditions.
Could you give me some suggestion about?
Than you very much!
Regard
Maurizio
