Rename uploaded files
Hi, I'm uploading images (represented by a FileField) and I need to rename those files when they are uploaded. I want them to be formated like that "%d-%d-%s.%s" % (width, height, md5hash, original_extension) I've read the documentation and I think a need to write my own FileSystemStorage class but how can I get the md5 hash and the image resolution if the file isn't saved yet ? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

How to rename uploaded files in FileField?
I've searched this group and find some related mails, but their solutions seem out of date, for example: http://gulopine.gamemusic.org/2007/nov/07/customizing-filenames-without-patching/ but there is no _save_FIELD_file method there, the underline file storage system had been refactored in 1.0 release. so anyone who know how to do it? thanks very much. -- Chen Yingliu --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: How can I rename uploaded files to a random filename?
If you just want to upload some files you might do something like the
following. The save function uses plain python to save the files to the
FILE_UPLOAD_DIR you defined in your setting file. You can play around with
the file names as much as you want here.
Question: Why a random name?
Vincent
class Application_files(forms.Form):
cv = forms.Field(label = 'CV *', widget = forms.FileInput(),
help_text="pdf or Word document")
paper = forms.Field(label = 'Paper *', widget = forms.FileInput(),
help_text="pdf or Word document")
def save(file,key,user,ext,overwrite=True):
if ext in ['pdf','doc']:
f = open('%s%s_%s.%s' %
(settings.FILE_UPLOAD_DIR,key,user,ext,),'wb')
f.write(file)
f.close()
def apply(request):
if request.POST:
for i in request.FILES.keys():
ext = request.FILES[i]['filename'][-3:].lower()
file = request.FILES[i]['content']
save(file,i,request.user,ext.lower())
else:
form = Application_files()
return render_to_response('apply/apply.html',{'form':form,})

How can I rename uploaded files to a random filename?
We upload all of our images via the Admin app and would like all uploaded images to be renamed to a set of numbers. We can generate the random numbers fine, but is there an easy way to rename the file once it's uploaded in the Admin app?
