How to use static file in ImageField by default?

Question

Django

If you specify a default file in the field, then when creating new instances of the model - instead of using all instances of one file - many copies of this file are created at the root. How can this be avoided?
...
app/
└── static/
│ └── img.png # instead of using this file

└── models.py

...
class ModelWithDefaultStaticImage(models.Model):
    image_file = models.ImageField(default='img.png')

img_iGJ3tYB.png # a copy is created for each instance of the model
...

Answer 1

Doing on the advice of Dr. Bacon Set
the model to Null

class officeUsers(models.Model):
    ....
    photo = models.ImageField(verbose_name='Фотография',
                              upload_to='photos/%Y/%m/%d',
                              blank=True)
    ....

Checking in the template

<div class="user_img">
      <img src="{% if user.photo %}{{ user.photo.url }}{% else %}{% static 'sysadmins/img/avatar.jpg' %}{% endif %}" alt="">
</div>

Make null, and when output, check and slip the desired one

Answer 3

Did something like this. Implemented something like this:
When creating a user, he is randomly assigned one and a static image, then this image is created with the same name in the / media / folder, if it was not there. Next, just slip the correct path of this picture in / media / into the model
