Add a div element only if there is a background image present

I am facing a situation where I need to display an image as the background of a div only if it is available. If the image is not present, I do not want the div to be visible at all. I am working with django templates and here is my current approach:

{% if post.image %}
    <div class="background"></div>
{% endif %}

Here is the CSS code for the div:

.background{
  position: absolute;
  z-index: -1;
  background-image: url("{{ post.image.url }}");
  width: 100%;
  height: 400px;
}

The images are stored in AWS S3. The issue I am facing is that when there is no image associated with the object, the page fails to load and throws an error stating that the 'image' attribute does not have a file associated with it. How can I resolve this issue?

Answer №1

Make sure to incorporate validation in your CSS code and display the image only if it is available:

.background{
  position: absolute;
  z-index: -1;
  {% if post.image %}background-image: url("{{ post.image.url }}");{% endif %}
  width: 100%;
  height: 400px;
}
