How do I get metadata ( width and height) of a cloudinary resource in Django

jikdo Member Posts: 4

I'm using cloudinaryfield to upload images and videos in my app. I need a way to get the width abd height of the images abd videos uploaded. I can't find any attribute on CloudinaryResource class that can help. And calling the api for the metadata makes my server slow and I get rate limited. Does cloudinaryfield store the metadata of width and height after upload and where can I find it?

    Hi there,

    A couple of options come to mind.

    • On upload, the height and width are returned as part of the response. Sample response:
      "asset_id": "b5e6d2b39ba3e0869d67141ba7dba6cf",
      "public_id": "eneivicys42bq5f2jpn2",
      "api_key": "312924996162147",
      "version": 1570979139,
      "version_id": "98f52566f43d8e516a486958a45c1eb9",
      "signature": "abcdefghijklmnopqrstuvwxyz12345",
      "width": 1000,
      "height": 672,
      "format": "jpg",
      "resource_type": "image",
      "created_at": "2017-08-11T12:24:32Z",
      "tags": [],
      "pages": 1,
      "bytes": 350749,
      "type": "upload",
      "etag": "5297bd123ad4ddad723483c176e35f6e",
      "placeholder": false,
      "url": "",
      "secure_url": "",
      "access_mode": "public",
      "original_filename": "sample",
      "eager": [
        { "transformation": "c_pad,h_300,w_400",
          "width": 400,
          "height": 300,
          "url": ",h_300,w_400/v1570979139/eneivicys42bq5f2jpn2.jpg",
          "secure_url": ",h_300,w_400/v1570979139/eneivicys42bq5f2jpn2.jpg" },
        { "transformation": "c_crop,g_north,h_200,w_260",
          "width": 260,
          "height": 200,
          "url": ",g_north,h_200,w_260/v1570979139/eneivicys42bq5f2jpn2.jpg",
          "secure_url": ",g_north,h_200,w_260/v1570979139/eneivicys42bq5f2jpn2.jpg" }],
      "media_metadata": {
        "PerspectiveHorizontal": "0",
        "RedHue": "0",
        "Exposure": "0.0",
        "ExposureTime": "1/320" 

    • Alternatively, you can make an Admin API call to get the details of a single resource. In the response will be the height and width. The response is similar to what you would get after uploading. Covered in the docs here:

    Hi @jikdo ,

    You can integrate Cloudinary's uploading capabilities into your forms and models using Cloudinary's helper classes. For example, you can define a model class with a CloudinaryField for image uploads. When a file is uploaded via this field, you can catch the upload response in your view or form handling the upload.

    Here's a sample Django model with a CloudinaryField:

    from cloudinary.models import CloudinaryField
    class MyModel(models.Model):
        image = CloudinaryField('image')

    In your view handling the form submission, you can catch the upload response like this:

    def upload(request):
        if request.method == 'POST':
            form = MyForm(request.POST, request.FILES)
            if form.is_valid():
                instance =
                # The upload response is now in instance.image

    Please refer to the Cloudinary Django documentation for more details.

    Best Regards,

    I'm using Django Rest, so I'm dealing with serializers and not forms. Can I get an example for using a Django Rest Serializer? or returns the model object instance, accessing the image attribute returns CloudinaryResource

    I try to access the metadata attribute it always returns None

    This function that adds the metadata when creating a new CloudinaryResource in CloudinaryField,

    function is from_db_value it calls parse_cloudinary_resource , which gets it's information from the url, since the url doesn't have the metadata information , it never returns it.

    Hi @jikdo ,

    Thanks for waiting.

    Can you please try this:

    i.e. when initializing CloudinaryField you can specify the names of width_field and height_field that will keep corresponding values.

    Hope this helps.
