uploads_in_blob in MongoDBAdapter doesn't let upload file to folder

[Francisco Costa]

Why is MongoDBAdapter with uploads_in_blob = True?

By default I can't upload a file using

import os
db.define_table(
    'data_file',
    Field('title'),
    Field('file', 'upload', uploadfield=True, uploadfolder=os.path.join(request.folder, 'uploads/'))
)

I get this error:

1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20.

If I turn uploads_in_blob = False in DAL (line 5255) the file is created on the uploads directory.

Could we make uploads_in_blob an adapter_args?

Something like this:

    db = DAL('mongodb://localhost/%s' % request.application,
            pool_size=10,
            adapter_args={'safe': False, 'uploads_in_blob': False},
        )
