You can do
fruit = get_object_or_404(Fruit, name=fruit_name)
but i wont recommend doing this with field that is not unique because it
basically resolves to Fruit.objects.get(name=fruit_name) which will raise
error if there are two objects with the same name... Furthermore you have
choices.. which means you have limited values to choose from.. Either
change your field to unique=True and remove choices or don't use this
method to get objects..
Hope I helped..
