Django - RecursionError: maximum recursion depth exceeded while calling a Python object

Question

I came across an error that was poorly explained when I wanted to customize the magic str function of my "ApiCall" model.

My Model :

FOO = 1
FOO2 = 2
FOO3 = 3
ROUTES = (
    (FOO, "foo"),
    (FOO2, "foo 2"),
    (FOO3, "foo 3"),
)


class ApiCall(TimeStampedModel):
    user = models.ForeignKey(MobileUser, on_delete=models.CASCADE)
    route = models.PositiveSmallIntegerField('foo', choices=ROUTES)

    def __str__(self):
        return f"... {self.get_route_display}"

Error :

RecursionError: maximum recursion depth exceeded while calling a Python object

The problem is very simple but I find it badly explained, you just have to add parenthesis when you call the get_route_display function. like this :

def __str__(self):
  return f"... {self.get_route_display()} ..."

PS: This function is automatically created from the "route" field in the model
