I don't exactly want to save the full path of the image in the database, just the image extension. I am trying to convert the current implementation of a PHP web page to Django. Here's how the table looks like, I'll be more explicit with the img ext this time:
id name img_ext ----------------------------- 1 Pluto jpg 2 Scooby gif I know in advance that all my pet images will be stored at the location /usr/django/images/. So, I can locate the Pluto image with its unique id. Pluto: /usr/django/images/1.jpg Scooby: /usr/django/images/2.gif I was thinking the best way to do the above is by overriding the save method. What I have in mind is: - Upload the image using ImageField - Update the column img_ext to the image extension of the above image The original image upload mechanism might look strange to some but that's how it is and I am just doing a simple conversion to Django.
