How do I get the object if it exists, or None if it does not exist?

Question

When I ask the model manager to get an object, it raises DoesNotExist when there is no matching object.

go = Content.objects.get(name=\"baby\")

I was facing with the same problem too. It's hard to write and read try-except for each time when you want to get an element from your model as in @Arthur Debert's answer. So, my solution is to create an Getter class which is inherited by the models:

class Getter:
    @classmethod
    def try_to_get(cls, *args, **kwargs):
        try:
            return cls.objects.get(**kwargs)
        except Exception as e:
            return None

class MyActualModel(models.Model, Getter):
    pk_id = models.AutoField(primary_key=True)
    ...

In this way, I can get the actual element of MyActualModel or None:

MyActualModel.try_to_get(pk_id=1)
