Django get parameter from url in Template to set CSS-CodePudding

I have a dynamic category menu list in my template that I would like to highlight (set active) when the url parameter matches the menu item. Therefore when the page equals the menu item the category will be highlighted.

URL examples:

https://[domainname]/training/?category=1

https://[domainname]/training/?category=2

https://[domainname]/training/?category=3

{% for categories in category_list %}
    <a href="{% url 'training' %}?category={{categories.Category_id}}" >
{% endfor%}

CodePudding user response：

You should move your if block before displaying the a tag, add active class only when your if condition is fulfilled, like that:

{% for categories in category_list %}
 
   {% if request.GET.category == 'categories.Category_id' %}
<a href="{% url 'training' %}?category={{categories.Category_id}}" >
  
  {% else %}
  <a href="{% url 'training' %}?category={{categories.Category_id}}" >
 {% endif %}

{% endfor%}

Just verify the condition if it's really select the case you want or not.
