I usually use template inheritance in my navigation, in a similar way to the answer alecxe linked to. However, it is possible to compare the use the current URL in an if tag, as you are trying to do.

The url tag allows you to save the result to a variable. You can then use that variable in your if tag.

{% url 'home' as home_url %}
<a href="{{ home_url }}" {% if request.get_full_path == home_url %}class="active"{% endif %}>Home</a>

Very old thread! My answer might help future readers.
I did that this way (just compare request URL name with your pathname)

<a class="nav-link {% if request.resolver_match.url_name == 'index' %}active{% endif %}" href="#">Home</a>

if your app has a namespace (let say blog) then:

<li class="nav-item">
  <a
    class="nav-link{% if request.resolver_match.namespace == 'blog' and request.resolver_match.url_name == 'post_list' %} active{% endif %}" 
    href="{% url 'blog:post_list' %}">
    Blog
  </a>
</li>

remember to define app_name in blog/urls.py:

app_name = 'blog'
urlpatterns = [
    path('', views.post_list, name='post_list'),
    # ...
]

The templatetags are very useful for this kind of need. Moreover, the templatetag can access the context and the request. Use the following as an idea to tailor up based on your needs.

# yourapp/templatetags/utils.py

from django import template
from django.urls import reverse

register = template.Library()


@register.simple_tag(takes_context=True)
def get_active_class(context, url_to_check: str) -> str:
    request = context['request']
    if request.get_full_path() == reverse(url_to_check):
        # this could be in the settings or in the app config
        return "is-active"
    return ""

In your sidebar you can now create a link easily

# your sidebar.html somewhere in your code

{% load utils %}

 <ul class="menu-list">
    <li>
      <a 
         href="{% url 'home' %}"
         class="{% get_active_class 'home' %}">Home
     </a>
    </li>

    <li>
      <a 
         href="{% url 'settings' %}"
         class="{% get_active_class 'settings' %}">Home
     </a>
    </li>
 </ul>
