Preview the photo after selecting the file in Django

Question

I can not find information on this topic. How to easily create a preview of the photo in Django after selecting it (before saving the form). As on the video below:

Is there any simple plugin that will enable this? I think that sending photos in this mode is very popular (that is, a thumbnail of the photo, before saving the whole model).

Answer 1

In your django template you can write a small script to display the preview of the image selected by the user. In template:

<!-- To display image -->
<img id="myimage" src="xyz" > </div>

<!-- To upload new image -->
<input name="images" onchange="readURL(this);" type="file" accept="image/*"/>

In the same template:

<script>
function readURL(input) {
    if (input.files && input.files[0]) {
        var reader = new FileReader();

        reader.onload = function (e) {
            $('#myimage').attr('src', e.target.result);
        };

        reader.readAsDataURL(input.files[0]);
    }
}

</script>
