Answer 1

I solved the issue by installing "Document Management System" module and attaching the files to "ir.attachment" instead of storing them as a binary field.Now you can download the document from the attachments.

code :

filename="/home/cryosave_qrcodes/xyz.pdf"
files = open(filename,'rb').read().encode('base64')
ir_values={
            'name':image_name,
            'datas_fname': image_name,
            'type':'binary',
            'datas':files,
            'create_uid':uid,
            'partner_id':ids[0],
            'res_model':'res.partner',
            'res_id':ids[0],
        }
 self.pool.get('ir.attachment').create(cr,uid,ir_values,context=context)

Fetch what file you want use read and write function in python.

import os
path = os.path.join(os.path.expanduser(),('~'), 'documents', 'python', 'file.txt')
fh = open(path,"w")
fh.write("Hello World")
fh.close()
