Hello, well after doing the tutorial I will try to do simple
things, like log into a system, and depending if the user is Client
or Admin it will show diferents webpages, Im planing this to start
having a better understanding of the "how does it work".
SO lets say I have a DB with users and privileges, so at the login
page will log on as client or admin,
I was reading how to schive this simple thing, but hadn't been able
to figure it out. As far as I understadn I must delegate this to
the EOF with some especial class and special operation, just I
can't find it.
or.. if there is other easier way to do it with WO/EO, then can I
get some help, even don;t telling me the "how" otherwise it will
take the "magic" away, but the "where" can i find info.
Here is something to get you thinking:
String userID; // From your login page
String password; // From your login page
Session session = (Session)session();
// You need to write session.setUser() and
User.authenticatedUserFromCredentials()
session
.setUser
(User
.authenticatedUserFromCredentials(session.defaultEditingContext(),
userID, password);
if (person == null) {
// Handle failure to log in, then
return context().page();
}
// You need to define ADMIN_PRIVILEGE_KEY and write
Privilege.privilegeWithKey()
Privilege adminPrivilege =
Privilege.privilegeWithKey(session.defaultEditingContext(,
Privilege.ADMIN_PRIVILEGE_KEY);
if (session.user().privileges().containsObject(adminPrivilege)) {
return pageWithName(AdminHomePage.class.getName());
}
return pageWithName(HomePage.class.getName());
If you are having a problem actually figuring out how to fetch and
authenticate the User, I enhanced the wiki with some simple examples
of the different ways to qualify and create a fetch in EOF:
