ImageField validation problem

Reported by: lucalenardi Owned by: jacob
Component: Forms Version: master
Severity: Keywords: 2070-fix
Cc: boobsd@…, justin.driscoll@… Triage Stage: Ready for checkin
Has patch: yes Needs documentation: no
Needs tests: no Patch needs improvement: no
Easy pickings: UI/UX:

Description

form.cleaned_data[image_field].read() seems to be empty when validating with custom validation using newforms.

...
if hasattr(data, 'temporary_file_path'):
    file = data.temporary_file_path()
else:
    if hasattr(data, 'read'):
        file = StringIO(data.read())
    else:
        file = StringIO(data['content'])
...

data.read() in the clean() method of ImageField becomes empty after the first read making the file unreadable in next custom validation.

With custom validation, I mean implementing the clean_fieldname() method in a form using newforms.
