How to delete an ImageField image in a Django model

问题

I have a Profile model like so:

class Profile(models.Model):
    photo = models.ImageField(upload_to="img/users/", blank=True)

I want my users to be able to remove their profile pictures so that there's no image in photo i.e blank.

I tried Profile.objects.get(id=1).photo.delete(save=False) which deleted the image but the url was still there so I was getting a 404. How do I clear the image and url?

EDIT: In my template, I'm like:

{% if profile.photo %}
    <img src="{{ MEDIA_URL }}{{ profile.photo }}" />
{% else %}
    <img src="{{ MEDIA_URL }}img/avatar.jpg" />
{% endif %}

Change Profile.objects.get(id=1).photo.delete(save=False) to Profile.objects.get(id=1).photo.delete(save=True)
