extract pdf file contents in a binary filed

Question

The scenario is this,
I have a class with binary field,
*file_to_import = fields.Binary('File')*
*file_to_import_fname = fields.Char('Filename')*
The file to be submitted to this field is in predefine format and if of type PDF.*
*
I have a button next to the binary field in view*, Import. *The related action uses tabula, parse through file and retrieve table contents in it and create records.*
*
*How do I pass the base64 encoded string to Tabula. The line to read PDF contents in tabula is,
*
*df

I can read the contents of the file with this technique.
pdf_file = open('/tmp/pdffile.pdf','w')
pdf_file.write((base64.b64decode(obj.file_to_import)))
pdf_file.close()
df = tabula.read_pdf("/tmp/pdffile.pdf", output_format="json", pages="all")
