Cuba Platform - Copy Action - cuba-platform

Question

I'm new to Cuba Platform and I'm trying to add functionality to copy a record in a table. Essentially the same functionality as found in the Administration -> Users -> Copy User screen.
The button action for this is usersTable.copy
Adding a similar action for example booksTable.copy doesn't seem to work natively. What method do I need to add or anything else to get this to work?
I've gone through the documentation and there's only an example using usersTable.
Many thanks in advance

The users copy action is not something that is generally available (like the create action). But you can look at the implementation from the copy action of the users browser.
Basically it just copies the data from the old user (roles, security group etc.) and prefills the data and then just opens the normal editor of the user like this:
public void copy() {
// fetches the selected user
Set<User> selected = usersTable.getSelected();
User selectedUser = selected.iterator().next();
selectedUser = dataSupplier.reload(selectedUser, "user.edit");
// creates a new user
User newUser = metadata.create(User.class);
// copies the roles and other stuff
if (selectedUser.getUserRoles() != null) {
List<UserRole> userRoles = new ArrayList<>();
for (UserRole oldUserRole : selectedUser.getUserRoles()) {
//...
userRoles.add(role);
}
newUser.setUserRoles(userRoles);
}
newUser.setGroup(selectedUser.getGroup());
// opens the editor with the pre filled data from the other user
AbstractEditor editor = openEditor("sec$User.edit", newUser //...
}

My solution with Cuba-Platform Tools:
public void copy() {
Books selected = booksDs.getItem();
CommitContext context = new CommitContext();
Books copy = metadata.getTools().deepCopy(selected);
copy.setId(uuidSource.createUuid());
copy.setBookName("(COPY) " + booksDs.getItem().getBookName());
context.addInstanceToCommit(copy);
dataManager.commit(copy);
booksDs.refresh();
}
