TemplateSyntaxError: Variable 'user.profile.photo' is an invalid source - python-3.x

Question

I have problem with accessing by the link. I am using easy-thumbnail framework, and I created simple view for user list to list all existing users.
Error message:
django.template.exceptions.TemplateSyntaxError: Variable
'user.profile.photo' is an invalid source.
Django Traceback throws me to this view.
views.py file:
#login_required
def user_list(request):
users = User.objects.filter(is_active=True)
return render(request,
'account/user/list.html',
{'section': 'people',
'users': users})
urls.py file:
path('users/', views.user_list, name='user_list'),
template list.html:
{% extends "base.html" %}
{% load thumbnail %}
{% block title %}People{% endblock %}
{% block content %}
<h1>People</h1>
<div id="people-list">
{% for user in users %}
<div class="user">
<a href="{{ user.get_absolute_url }}">
<img src="{% thumbnail user.profile.photo 180x180 %}">
</a>
<div class="info">
<a href="{{ user.get_absolute_url }}" class="title">
{{ user.get_full_name }}
</a>
</div>
</div>
{% endfor %}
</div>
{% endblock %}
sample code from base.html:
<li {% if section == "people" %}class="selected"{% endif %}>
People
</li>
models.py:
class Profile(models.Model):
user = models.OneToOneField(settings.AUTH_USER_MODEL,
on_delete=models.CASCADE)
date_of_birth = models.DateField(blank=True, null=True)
photo = models.ImageField(upload_to='users/%Y/%m/%d/',
blank=True)
def __str__(self):
return f'Profile for user {self.user.username}'
Thank you for the helping in advance.

Answer 1

Reviewed the documentation https://easy-thumbnails.readthedocs.io/en/latest/usage/#templates. Creates a thumbnail from an object (usually a file field). I tried it and it helped solve my problem:
<img src="{{ user.profile.photo.url }}">

Answer 2

I had this problem too. You can solve the problem with the following solution:
Instead of users = User.objects.filter(is_active=True), use profiles = Profile.objects.all()
Change as follows: return render(request,'account/user/list.html',{'section': 'people', 'profiles': profiles}).
In the list.html file, change as follows:
{% extends 'base.html' %}
{% load thumbnail %}
{% block title %}People{% endblock %}
{% block content %}
<h1>People</h1>
<div id="people-list">
{% for profile in profiles %}
<div class="user">
<a href="{{ profile.user.get_absolute_url }}">
<img src="{% thumbnail profile.photo 180x180 %}" alt="{{ profile.user.last_name }}">
</a>
<div class="info">
<a href="{{ profile.user.get_absolute_url }}" class="title">
{{ profile.user.get_full_name }}
</a>
</div>
</div>
{% endfor %}
</div>
{% endblock %}
