How to save a user's photo and change it?

Question

Django

For some reason I can't figure out how to save user files/photos to a folder and change them.
You can give an example of an ImageField to anyone who is not difficult - models.py, views.py, html on DJANGO.

Answer 1

models.py

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

Here is from the template

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