Django Image upload issue Cloundinary

Question

I'm learning Django at present and just about getting to the deployment stage at hit a problem serving static/media with Cloudinary, following guides how to do this, it seems straight forward enough. I've checked the Cloudinary support but I can't find anything to help, just wondering if anyone has any input.

The problem I have is that I am using Exiffield (to get image info) and ImageSpecField from ImageKit to resize the images for thumbnails and I think this is giving me problems with Cloudinary.

Firstly I can't upload images from Admin, I get an error:

Exception Value:Empty file

Secondly I get another error:

400 Client Error: Bad Request for url: https://res.cloudinary.com/ path to file

when trying to open my site (which is being served locally and in development

This is using ImageField as upload. I would change it to CloudinaryField but my model heavily relies on ExifField which wont read from it.

Model below.

class Photo(models.Model):
image = models.ImageField(upload_to='images')
mid_thumbnail = ImageSpecField(source='image',
                                  processors=[ResizeToFit(220, 150)],
                                  format='JPEG',
                                  options={'quality': 100})
gallery_thumbnail = ImageSpecField(source='image',
                               processors=[ResizeToFit(300, 250)],
                               format='JPEG',
                               options={'quality': 100})
gallery_detail = ImageSpecField(source='image',
                                   processors=[ResizeToFit(1000, 850)],
                                   format='JPEG',
                                   options={'quality': 100})
title = models.CharField(max_length=100)
albums = models.ManyToManyField(Album, blank=True, related_name='photos')
feature_image = models.BooleanField(default=False)
description = models.CharField(editable=False, max_length=150, blank=True)
posts = models.ManyToManyField(Post, blank=True, related_name='pictures')

lens = models.TextField(editable=False, max_length=100, default='Lens Data')
caption = models.CharField(editable=False, max_length=1000, default='Caption info')
file_size = models.CharField(editable=False, max_length=20, default='File_size')
width = models.IntegerField(blank=True, null=True, editable=False)
height = models.IntegerField(blank=True, null=True, editable=False)
categories = models.ForeignKey(Category, on_delete=models.CASCADE, null=True, blank=True)
objects = models.Manager
info = models.TextField(default='**info empty**', blank=True, help_text="editable caption info no reversable")
exif = ExifField(source='image', denormalized_fields={'lens': exifgetter('LensID'),
                                                      'caption': exifgetter('Description'),
                                                      'file_size': exifgetter('FileSize'),
                                                      'description': exifgetter('Headline')

                                                      })


def save(self, *args, **kwargs):
    super(Photo, self).save(*args, **kwargs)
    """Get EXIF"""
    im = Image.open(self.image.path)
    try:
        info = im.getexif()[0x010e]
        self.info = info
    except KeyError:
        pass
    """Save image dimensions."""
    im = Image.open(pjoin(MEDIA_ROOT, self.image.name))
    self.width, self.height = im.size
    im.save(self.image.path)
    super(Photo, self).save(*args, **kwargs)

def __str__(self):
    return self.title

def albums_(self):
    lst = [x[1] for x in self.albums.values_list()]
    return ",".join(lst)

def size(self):
     return "%s x %s" % (self.width, self.height)```

Answer 1

Thanks for that info Much appreciated. But I actually swapped to S3, which gave me same problems but with more complete error messages so i could solve the problem.

self.image.path in the model save method was the issue. I just changed it to self.image and it worked. The problem was using absolute path to the object which is not supported by S3 or I assume Cloudinary.
