I am working on a project and jhave a slight confusion.

The Djago Template index.html has following code:

  <div class="carousel-item active">
      {% for i in products|slice:"0:"%}
        <div class="col-xs-3 col-sm-3 col-md-3">
          <div class="card" style="width: 17rem;">
              <div class="card-body">
              {% for img in i.images.all %}
                  {% if forloop.counter == 1 %}
                  <img src={{img.img_url}} class="card-img-top" alt="...">
                  {% endif %}
               {% endfor %}

                <h6 class="card-title">{{i}}</h6>
                   {% for skus in i.skus.all %}
                                        {% if forloop.counter == 1 %}
                  <h6 class="card-price">{{skus.price}} {{skus.currency}}</h6>
                                        {% endif %}
               {% endfor %}
                <a href="#" class="btn btn-primary">Add to Cart </a>
            </div>
          </div>
        </div>
        {% endfor %}
      </div>

In this code , Is there a way to eliminate the {% for skus in i.skus.all %}

The all tag is getting all objects but I am restricting the loop to run only one time through if condition so that I can only get the first item.

Is there a way to eliminate the loops that have .all in them and restrict the statement to run only one time though any other way.

You can achieve by using either with tag to set a variable or direclty us as:

{% with skus=i.skus.first %}
    <h6 class="card-price">{{skus.price}} {{skus.currency}}</h6
{% endwith %}

or

<h6 class="card-price">{{i.skus.first.price}} {{i.skus.first.currency}}</h6

Are you looking for the first queryset method ?

<div class="card-body">
  <img src={{i.images.first().img_url}} class="card-img-top" alt="...">
</div>
