App has Game model and Player model.

I want to get a list of the Game objects in which the logged in user has a Player. This is to show that user’s Game history in a dashboard so they can see past games.

This code gets all the Game objects. So it shows the history of every user.

class DashboardListView(generic.ListView):
    model = Game
    template_name = 'dashboard.html'
    context_object_name = 'tournament_list'

    def get_queryset(self):
        return Game.objects.filter()

I can narrow down to completed games for every player like this:

class DashboardListView(generic.ListView):
    model = Game
    template_name = 'dashboard.html'
    context_object_name = 'tournament_list'

    def get_queryset(self):
        return Game.objects.filter(completed=True)

I tried this to get to narrow down to only games of the specific user:

def get_queryset(self):
        if Player.objects.filter(owner=self.request.user).exists():
            mine = Player.objects.filter(owner=self.request.user).get()
            return Game.objects.filter(
            Q(player1=mine) | Q(player2=mine) | Q(player3=mine) & Q(completed=True))
        

But because there are multiple Player objects it throws this error:

get() returned more than one Player -- it returned 12!

What I want are the 12 Games in which the user has those 12 Player objects.

How can I get those Game objects in which the user has a Player object?
