How to add a class to the active menu item in django mtpp?

Question

Django

My menu code

<ul class="header_ul navbar-nav mt-2 mt-lg-0 margin-auto">
                    {% recursetree menu_top %}
                    <li class="nav-item{% if not node.is_leaf_node %}dropdown{% endif %}">
                        <a {% if node.slug in request.path %} class="current" {% endif %} {% if not node.is_leaf_node %}class="dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"{% else %} href="/{{node.slug}}"{% endif %}>{% if node.icon %}<i class="fa {{node.icon}}"></i> {% else %}{% endif %}{{node.title}}</a>
                        {% if not node.is_leaf_node %}
                        <ul class="dropdown-menu" aria-labelledby="navbarDropdown">
                          {{children}}
                        </ul>
                        {% endif %}
                    </li>
                    {% endrecursetree %}
                  </ul>

This code works, but there are requests in the filter such that the request.path includes the slug of some items, and, in fact, they become active. For example, such a request /handbooks/viewofcargo/passazhirskie/ includes two menu items (cargo and handbook) and there are many such requests. How to exclude such moments?

Answer 1

As an option, write a template filter that will wrap node.slug with slashes

@register.filter
def to_path(value):
    return '/' + value + '/'
