Saving file uploaded via ajax to Django model ImageField

Question

The file is available as raw data in the request. How am I supposed to transform it to be saved on the disk represented by the ImageField inside a model.

Tried stuff:

file_ = File(request)
modelinstance.picture.save(filename, file_, save=False)
modelinstance.save()

and some variants of the above. An example on how to do this inside the django view would help.

Thanks!

If you used a ModelForm, you wouldn't have anything special to do. ModelForm handles FileField/ImageField automatically.

If you really want to do it manually, django has docs

That's only part of the question. The actual question is that my file is not in request.FILES since it is a ajax XHR request. So how do I read it from there and assign to my ImageField – Pratik Mandrekar Oct 22 '12 at 16:32
You mean you have the file base64-encoded or something similar, inside the XHR request? That's interesting. Check what the file-field wants. A file object? Does it need to be already saved on disk? – Lars Wikman Oct 22 '12 at 19:55
It is very complex to upload a file via ajax, this plugin makes it easy http://www.malsup.com/jquery/form/ Also you should improve your question, how is it that "your file is not in request.FILES" in a comment and not in the question ? humhum ... – jpic Oct 23 '12 at 08:36

Solved it like this

filename = request.GET[ 'yourfilename' ]

from django.core.files.uploadedfile import SimpleUploadedFile
file_contents = SimpleUploadedFile("%s" %(filename), request.raw_post_data)

modelinstance.picture.save(filename, file_contents, True)
