Django template compare two variables not working

Question

I am building a pagination with Django and Bootstrap. There is this variable pageNum which is passed from my views.py and indicates the current page. I use a for loop to generate the pagination. The pagination itself is fine but when I compare forloop.counter to pageNum to add the class="active" to the current li its not working. But when I actually print the values of pageNum and forloop.counter they are identical. Here is the code:

 <ul class="pagination">
 {% for pagination in paginationInfo %}
      <li {% if forloop.counter == pageNum %} class="active" {%endif%} ><a href="{{pagination}}">{{forloop.counter}}</a></li>
 {% endfor %}
 </ul>

Answer 1

You are probably passing the pageNum as string into the template. To compare it, you need to cast it into an int in your view or use the add filter:

<ul class="pagination">
 {% for pagination in paginationInfo %}
    <li {% if forloop.counter == pageNum|add:"0" %} class="active" {%endif%} ><a href="{{pagination}}">{{forloop.counter}}</a></li>
 {% endfor %}
</ul>
