For example, you have a simple Django model 'Film':

from django.db.models.base import Model
from django.db.models import CharField, ImageField

class Film(Model):
  name = CharField(max_length=255, null=False)
  poster = ImageField()

And you try to show the image field in the django template when it is not set.

<h1>Film info</h4>
<h2>{{ film.poster.url }}</h2>       
<br><img src="{{ film.poster.url }}">

To solve this problem, it is enough to add an if statement:

<h1>Film info</h4>
<h2>{{ film.poster.url }}</h2>
{% if film.poster %}       
<img src="{{ film.poster.url }}">
{% else %}
<img src="url or path to some your default image">
{% endif %}

The situation is similar in python code.

film_info = {
  "poster": film.poster.url


film_info = {
  "poster": film.poster.url if film.poster else "url or path to some your default image"

Don't use hasattr(film.poster, 'url'). The error will be the same.
