How to display child element in Django MPTT? - django

Question

I am trying to call parent and child element of a model, I have gone through the MPTT model documentation. I did as mentioned on the documentation, but my template is failing to print children
What can be the possible cause of this problem?
Here is my Views:
def category_view(request):
category = Categories.objects.all()
brands = Brands.objects.all()
context ={
'category':category,
'brands':brands,
}
return render(request,'./ecommerce/categories.html', context)
and Here is my template HTML:
{% load mptt_tags %}
{% recursetree category%}
<div class="category-wrap mb-4">
<div class="category category-group-image br-sm">
<div class="category-content">
<h4 class="category-name">{{ node.name }}
</h4>
<ul class="category-list">
{% if not node.is_leaf_node %}
<li>{{children}}</li>
{% endif %}
</ul>
</div>
</div>
</div>
<!-- End of Category Wrap -->
{% endrecursetree %}
Parent element is printed but children element is not being printed

Doing a lot of hit and trial, generic approach solved my problem. Others having similar problem could be benefited from my answer, hence posting the solution.
Views:
category = Categories.objects.filter(parent=None)
Template:
{% for category in categories %}
<div class="category-wrap mb-4">
<div class="category category-group-image br-sm">
<div class="category-content">
<h4 class="category-name">{{ category.name }}
</h4>
<ul class="category-list">
{% for cat in category.get_children %}
<li>{{ cat.name }} </li>
{% endfor %}
</ul>
</div>
</div>
</div>
<!-- End of Category Wrap -->
{% endfor %}
