I have simple model with overrided save() method, I want to save image from given url, every time save mehod is called.
Here is my code:
def save(self, *args, **kwargs):
super().save(*args, **kwargs)
# Creating URL to request
URL = "https://maps.googleapis.com/maps/api/place/photo?maxwidth=400&key=" + settings.KEY
URL += "&photoreference=" + self.reference
result = urllib.request.urlretrieve(URL)
self.image_file.save(
os.path.basename(self.reference),
File(open(result[0]))
)
self.save()
And this throws this error:
Exception in thread django-main-thread:
Traceback (most recent call last):

I found possible solution with addding:
with open(path, 'rb') as f:
contents = f.read()
But, now my question is: How can I use this piece of code to handle saving image in my save() function?
