How to search via Enums Django

I’m trying to a write a search function for table reserving from a restaurant, I have a restaurant model:

class Restaurant(models.Model):
    """
    Table Restaurant
    =======================

    This table represents a restaurant with all necessary information.
    """
    name = models.CharField(max_length=70)
    caterer = models.ForeignKey(Caterer, on_delete=models.CASCADE, null=True)
    address = models.OneToOneField(Address, on_delete=models.CASCADE, null=True)
    kitchen_type = models.IntegerField(choices=KITCHEN_TYPE, null=True)
    opening_hours = models.OneToOneField(OpeningHours, on_delete=models.CASCADE, null=True)
    description = models.CharField(max_length=2000, null=True)
    phone = models.CharField(max_length=15, null=True)
    parking_options = models.BooleanField(default=False)

which has a enum for kitchen_type:

KITCHEN_TYPE = [
    (1, "Turkish"),
    (2, "Italian"),
    (3, "German"),
    (4, "English"),
    (5, "Indian"),
]

And this is the search function in view.py:

def search_result(request):
    if request.method == "POST":
        searched = request.POST['searched']
        result = Restaurant.objects.filter(
            Q(name__icontains=searched) | Q(address__city__icontains=searched))
        return render(request, 'search_result.html', {'searched': searched, 'result': result})
    else:
        return render(request, 'search_result.html', {})

So how am I able to search for kitchen_type in the view?

Answer

Instead of using a list of tuples I would recommend extending the IntegerChoices or TextChoices classes provided by Django. Here’s an example of how you can use IntegerChoices:

>>> class KitchenType(models.IntegerChoices):
...     TURKISH = 1
...     ITALIAN = 2
...     GERMAN = 3
... 
>>> if 1 in KitchenType:
...     print(True)
... 
True
