Subject [jira] [Created] (TORQUE-182) Additional methods for handling associated objects
Date Sat, 25 Feb 2012 14:31:48 GMT
Additional methods for handling associated objects
--------------------------------------------------

                 Key: TORQUE-182
                 URL: https://issues.apache.org/jira/browse/TORQUE-182
             Project: Torque
          Issue Type: New Feature
            Reporter: Thomas Fox
            Assignee: Thomas Fox


Assuming complexObjectModel=true and objectIsCaching=true (the default settings for generation)
Consider a table (book) having a foreign key on another table (author).
Couurently, in the Author object, the method addBook() is implemented, by which a book can
be associated with the author and which adds it to the collection obtained by getBooks().
These books are also saved when the author object is saved.

However, there are no methods by which associations can be removed, an associated book can
be deleted or all associated books can be deleted.
It would be nice if one could do these operations on an object level and these operations
would be written to the database on save().
The first possibility to implement this would be to generate methods removeBook(), deleteBook()
and deleteAllBooks().
The other possibility would be to use a custom list object which intercepts the calls to the
add(), remove() etc methods and translates these operations to database operations (with the
problem that remove() can be interpreted as removing the association as well as deleting the
associated object, my preference being the latter)
