Whether stored as bytestrings or images, it is a bad practice to store
images in the database.
I believe from the problem description that what you are trying to
acomplish is store images which you receive in the form of a bytestring.
Have you considered converting the bytestring to an image and storing the
image in file system using normal imageField:
It would be something like this:
import base64
def _construct_image(bytestring):
img = open("imageToSave.png", "wb")
img.write(str.decode('base64'))
img.close()
In your django models, you use this function to convert the bytestring to an
image and store where upload_to
wants to store it.
Suppose you choose to overide the save method to handle the handle the
conversion, that will be something like:
def save(self, *args, **kwargs):
....
image = _construct_image(self.image)
....
return Super(YourModel, self).save(*args, **kwargs)
Check if it works.
