Django BooleanField if statement doesnt return content - django

Question

For some reason when checking to see if BooleanField post.featured is true I get no output. If I remove that it works fine but not as I intend.
<div class="carousel-inner">
{% for post in object_list%}
{% if post.featured is True %}<!-- This post.featured is BooleanField -->
{% if forloop.first %}
<div class="carousel-item active">
{% else %}
<div class="carousel-item">
{% endif %}
<div class="col-md-6 px-0">
<h1 class="display-4 font-italic">{{ post.title }}</h1>
<p class="lead my-3">{{ post.hook }}</p>
<p class="lead mb-0">
<a href="{% url 'article-details' post.pk %}" class="text-white fw-bold">
Continue reading...
</a>
</p>
</div>
</div>
{% endif %}<!-- and this -->
{% endfor %}
</div>
Heres how it looks like when not checking if post.featured == true:
However, content doesnt render with {% if post.featured is True %} or {% if post.featured %}
Can someone please explain what im doing wrong
EDIT:
Submiting my view:
class Home(ListView):
model = Post
template_name = 'home.html'

You should not filter in the template. This is not only inefficient, but a template is not meant to implement business logic, only rendering logic: a template should not be concerned with what it renders, it should only be concerned with rendering the data in a pleasant way.
You should filter in the ListView:
class Home(ListView):
model = Post
template_name = 'home.html'
queryset = Post.objects.filter(featured=True)
This will filter at the database side.
If you need both the featured items, and the ones that are not featured, you can make two queries:
class Home(ListView):
model = Post
template_name = 'home.html'
queryset = Post.objects.filter(featured=True)
def non_featured(self):
return Post.objects.filter(featured=False)
then you can render the non-featured items with:
{% for post in view.non_featured %}
…
{% endfor %}
