Django Custom image upload field with dynamic path

Question

I'm trying to create my own field type for uploading images, it won't be used in the django admin panel. I imagine the syntax would probably look something like:

photo = CustomImageField(upload_to='images', width="200", height="200")

I want to be able to set the parameters in the field when I upload and save an image. I've looked through the django documentation but I can't find anything about how to do this. So basically, I want to be able to control where the image is uploaded to and the width and height parameters when the upload form is processed and the object is saved.

I am using Django 1.2

Any help would be greatly appreciated :)

Answer 1

Your can change the storage of a FileField using the location property.

form_name.photo.storage.location = upload_dir_path      

It works for the FileField and maybe it will also work for your custom image field if you inherit the Django's ImageField.
