using config.groovy in gwt for user preference - grails

Question

I have a gwt and grails legacy app that I'm upgrading and modifying.. Its a reservation calendar basically with different "views".. the problem I'm having is I want the user to be able to choose a default view for themselves upon logging in..I've done this with a grails only application before but gwt is much different..how can I pass something from config.groovy to the gwt part that select which view to show..and this view isn't a view like a grails view..think of it like restaurants..and a user may only want to see the reservations for a particular restaurant instead of the default of all restaurants

Answer 1

Maybe not a direct answer to your question but you can just make a ordinary GWT remote service UserPreferencesService which will store user preferences
public interface UserPreferencesService extends RemoteService {
List<Restaurant> getRestaurants(Account user);
void setRestaurants(Account user, List<Restaurant> restaurants);
}
In your entry point you can then make a decision on what kind of view you'll show to user
public final class Application implements EntryPoint {
private AuthServiceAsync authService =
GWT.create(AuthService.class);
private UserPreferencesAsync preferencesService =
GWT.create(UserPreferencesService.class);
#Override
public void onModuleLoad() {
// handle login
authService.getAccount(new Callback<Account>() {
#Override
public void onSuccess(final Account account) {
// check if user have a preferred restourants
preferencesService.getRestaurants(account,
new Callback<Account>() {
#Override
public void onSuccess(final List<Restaurant> restaurants) {
// user did not select any restaurants yet.
// Show a selection widget
if (restaurants.isEmpty) {
RestaurantSelectorWidget widget =
new RestaurantSelectorWidget();
// your custom handler here
widget.addHandler(new Handler() {
#Override
public void onSelected(/*...*/) {
// save user preferences
// and switch to normal view
}
})
RootPanel.get("container")
.add(widget);
} else {
// show normal view
}
}
}
}
}
}
}
}
Also you may take look to this plugin which is adds GWT support to grails.
