Problem pagination for category posts in Django - django

Question

I used the following code for pagination and got the error I left here. please help.
Note that for categories whose number of posts is less than 2 (_paginator), there is no problem, but the same posts are more than two and pagination is done.
urls.py:
from django.urls import path
from . views import home, detail_article, category_list
app_name = "blog"
urlpatterns = [
path('', home, name="home"),
path('page/<int:page>', home, name="home"),
path('post/<slug:slug>', detail_article, name="detail_article"),
path('category/<slug:slug>', category_list, name="category_list"),
path('category/<slug:slug>/page/<int:page>', category_list, name="category_list")
]
views.py:
def category_list(request, slug, page=1):
category = get_object_or_404(Category, slug=slug, status=True)
article_list = category.articles.published()
_paginator = Paginator(article_list, 2)
articles = _paginator.get_page(page)
context = {
'category':category,
'articles':articles
}
return render(request, 'blog/category.html', context)
template.html:
<!-- Paginator -->
{% if articles.has_other_pages %}
<div class="col-12 pagging">
<ul>
{% if articles.has_previous %}
<li>
<a href="{% url 'blog:category_list' category.slug articles.previous_page_number %}">
<i class="fa fa-arrow-right" aria-hidden="true"></i></a>
</li>
{% else %}
<li><i class="fa fa-arrow-right a-active" aria-hidden="true"></i></li>
{% endif %}
<!-- {% for i in articles.paginator.page_range %} {% if articles.number == i %}
<li><span class="a-active">{{ i }}</span></li>
{% else %}
<li>{{ i }}</li>
{% endif %} {% endfor %} -->
{% if articles.has_next %}
<li>
<a href="{% url 'blog:category_list' category.slug articles.next_page_number %}">
<i class="fa fa-arrow-left" aria-hidden="true"></i>
</a>
</li>
{% else %}
<li><i class="fa fa-arrow-left a-active" aria-hidden="true"></i></li>
{% endif %}
</ul>
</div>
{% endif %}
<!-- end paginator -->
and error! :(

Answer 1

The HTML in comment is still rendered by the template engine. So you should remove the {% url 'blog:category' %} parts. If you want to put comment in a Django template, you do that between {# … #}, or you can use a {% comment %} … {% endcomment %} template block [Django-doc].
For example:
{% if articles.has_previous %}
<li>
<a href="{% url 'blog:category_list' category.slug articles.previous_page_number %}">
<i class="fa fa-arrow-right" aria-hidden="true"></i></a>
</li>
{% else %}
<li><i class="fa fa-arrow-right a-active" aria-hidden="true"></i></li>
{% endif %}
{% comment %}
<!-- {% for i in articles.paginator.page_range %} {% if articles.number == i %}
<li><span class="a-active">{{ i }}</span></li>
{% else %}
<li>{{ i }}</li>
{% endif %} {% endfor %} -->
{% endcomment %}
{% if articles.has_next %}
<li>
<a href="{% url 'blog:category_list' category.slug articles.next_page_number %}">
<i class="fa fa-arrow-left" aria-hidden="true"></i>
</a>
</li>
{% else %}
<li><i class="fa fa-arrow-left a-active" aria-hidden="true"></i></li>
{% endif %}

{% for i in articles.paginator.page_range %}
{% if articles.number == i %}
<li><span class="a-active">{{ i }}</span></li>
