save thumbnail image path django python - django

Question

i am generating thumbnail and i want to save image path to database when i upload from admin and api:
class Image(models.Model):
license_type = (
('Royalty-Free','Royalty-Free'),
('Rights-Managed','Rights-Managed')
)
image_number = models.CharField(default=random_image_number,max_length=12,unique=True)
title = models.CharField(default=random_image_number,max_length = 100)
image = models.ImageField(upload_to = 'image' , default = 'demo/demo.png')
thumbnail = models.ImageField(upload_to='thumbs')
category = models.ForeignKey('Category', null=True, blank=True, on_delete=models.CASCADE)
shoot = models.ForeignKey(ImageShoot, on_delete=models.CASCADE, related_name='Image', null=True,blank=True)
image_keyword = models.TextField(max_length=1000)
credit = models.CharField(max_length=150, null=True)
location = models.CharField(max_length=100, null=True)
license_type = models.CharField(max_length=20,choices=license_type, default='')
uploaded_at = models.TimeField(auto_now_add=True)
def __str__(self):
return self.title
def save(self, *args, **kwargs):
super(Image, self).save(*args, **kwargs)
if not self.make_thumbnail():
raise Exception('Could not create thumbnail - is the file type valid?')
def make_thumbnail(self):
fh = storage.open(self.image.path)
image = PILImage.open(fh)
image.thumbnail((400,400),PILImage.ANTIALIAS)
fh.close()
thumb_name, thumb_extension = os.path.splitext(self.image.path)
thumb_extension = thumb_extension.lower()
thumb_filename = thumb_name + '_thumb' + thumb_extension
temp_thumb = BytesIO()
image.save(temp_thumb, FTYPE)
temp_thumb.seek(0)
self.thumbnail.save(thumb_filename, ContentFile(temp_thumb.read()), save=True)
temp_thumb.close()
return True
this if we upload image from admin
admin.py:
#admin.register(Image)
class ImageAdmin(admin.ModelAdmin):
readonly_fields=['image_number','uploaded_at']
fields = ['title','image_number','shoot','category',
'image','image_keyword','thumbnail','credit','license_type','location','uploaded_at']
this is my views for api currently just uploading bulk image with out thumbnail how can i create thumbnail from this :
views.py:
class EventImageUploadView(APIView):
def post(self, request,category):
#title = forms.CharField(max_length = 100)
file = request.data['file']
data={
'image':file,
'category_id':category
}
EventsImage.objects.create(**data)
return JsonResponse(json.dumps({'message': "Uploaded"}), status=200, safe=False)
i get this error and its generating multiple images i dont know what causing recursion:
