How to save uploaded image url in database from Django?

[PrateekG]

Hi All,

I have implemented a functionality-upload image to S3 from Django2.0.6+Python3.6+MySql.
And this functionality is working fine.
Now I want to save the uploaded image url to 'image_url' field of a table- Brand in database.
My image uploading code (models.py) is as below-

class Brand(models.Model):
    name = models.CharField(max_length=60)
    description = models.TextField(blank=True, null=True)
    created_at = models.DateTimeField(auto_now_add=True, editable=False)
    updated_at = models.DateTimeField(auto_now=True)

    @property
    def logo(self):
        return get_logo(self.name, 'brand')

    class Meta:
        managed = False
        db_table = 'brand'

    def __str__(self):
        return self.name

def get_logo(logo_name, folder):
    logo_name_with_ext = '{}{}'.format(logo_name, '.png')
    logo_url = '{}/{}'.format(IMAGE_PATH, os.path.join(folder, logo_name_with_ext))
    return mark_safe('<img src="{}" height="20" />'.format(logo_url))

Can anyone please suggest me what changes should I make here?
