Basically, in the view you should just create a list of registered game names:
#login_required(login_url='/signin')
def home(request):
current_user = request.user
registered = GameControl.objects.filter(user=current_user)
unregistered = Game.objects.all()
return render(request, "games/home.html", {'unregistered': unregistered ,'registered_names': [reg.game_name for reg in registered] })
And then the template:
{% for un in unregistered %}
{% if un.game_name in registered_names %}
<button type="button" class="btn">{{un.game_name}}
<i class="material-icons" style="float:
right;">close</i></span></button>
<br>
{% else %}
<button type="button" class="btn">{{un.game_name}}
<i class="material-icons" style="float:
right;">arrow_forward</i></span></button>
<br>
{% endif %}
{% endfor %}
