I'm trying to add a bunch of files from disk into my django database.
Here's the helper function I've written so far:
def django_file(path, field_name, content_type):
# adapted from here:
http://groups.google.com/group/django-users/browse_thread/thread/834f988876ff3c45/
from django.core.files.uploadedfile import InMemoryUploadedFile
f = open(path)
return InMemoryUploadedFile(
file=f,
field_name=field_name,
name=file.name,
content_type=content_type,
size=os.path.getsize(path),
charset=None)
I'm calling it like so:
django_file("path-to-jpg-file", field_name="image",
content_type="image/jpeg")
Here's the error I'm getting:
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/home/amarder/Documents/nmis/odk_dropbox/views.py", line 49,
in import_instances_folder
f = django_file(xml_files[0], field_name="xml_file",
content_type="text/xml")

content_type, size, charset)

packages/django/core/files/uploadedfile.py", line 46, in _set_name
name = os.path.basename(name)
File "/home/amarder/Documents/environments/nmis/lib/python2.6/
posixpath.py", line 111, in basename
i = p.rfind('/') + 1
AttributeError: 'member_descriptor' object has no attribute 'rfind'
Any suggestions?
