Misleading FileField.save documentation, no reference to django.core.files.File

[Ethan Jucovy]

The documentation for FileField.save (​http://docs.djangoproject.com/en/dev/ref/models/fields/#django.db.models.FieldFile.save) claims:

Takes two required arguments: name which is the name of the file, and content which is a file-like object containing the file's contents.

This is incorrect; content is *not* a "file-like object" -- it's a django.core.files.File-like object.

Attempting to do field.save(name, open(my_file)) results in an AttributeError: 'file' object has no attribute 'chunks'. The correct spelling is instead field.save(name, django.core.files.File(open(my_file))).

I've attached a patch to the docs which makes this clear, and also refers the reader to the documentation about Django File objects.

These other tickets are related to FileField's documentation, but they don't describe this specific problem: #9535 (very broad), #15588 (already RFC), and #15646.

file_objects.diff fails to apply cleanly on to trunk

[Ethan Jucovy]

Original patch was generated from within the docs/ directory. New patch file_objects.2.diff should apply cleanly from the root of the checkout.
