Hi,

I use this code in my views for uploading file with a model form. It works correctly But I would like to know how to rename and decrease size file (if file is greater than 200 Ko) before uploading.

I need your help.

Django can’t do anything like this because Django doesn’t have the file until after it’s uploaded.

It _might_ be possible to find some JavaScript that _may_ be able to do this in the browser - but from what I know of the upload process, I kind of doubt it. (In either case, this isn’t a Django issue.)
