How to rename an image with FileField type. Please tell me how to do it in
*views* while uploading an image to S3.
import osfrom uuid import uuid4
def path_and_rename(path):
def wrapper(instance, filename):
ext = filename.split('.')[-1]
# get filename
if instance.pk:
filename = '{}.{}'.format(instance.pk, ext)
else:
# set filename as random string
filename = '{}.{}'.format(uuid4().hex, ext)
# return the whole path to the file
return os.path.join(path, filename)
return wrapper
FileField(upload_to=path_and_rename('upload/here/'), ...)
*The above code works well in models.py file but throws back error during
migration process. Please help me how can i solve this issue in views.py file
because once i place the above code in models.py it works very well but if
there is any change in model and i do a migration then it throws back an error.*
