Manish Bohra · Accepted Answer

Hello @rumaan Try This:
from odoo.exceptions import UserError
import mimetypes
from odoo.tools.mimetypes import guess_mimetype
file_name = fields.Char('File Name')
mimetype = None
if mimetype is None and self.file_name:
mimetype = mimetypes.guess_type(res.file_name)[ 0 ]
if not mimetype == 'pdf' :
raise UserError( 'Allowed Format Pdf' )

I can't answer directly to Jaiswal Shivam, but their answer is dangerous from a security standpoint. The attacker controls the file name and thus the validation can be bypassed by setting the expected extension (malicious_content.xlsx) but the content can be anything (e.g. php script).
The accepted answer using mimetype guessing is much better from a security standpoint.

Or you can also try this code::

# create a char field
file_data = fields.Binary('File')
file_name = fields.Char('File Name')
# Go to xml and
def check_file_type(self):
​if not self.file_name.endswith [1] ('.xlsx'): //Here you can define your file format like .pdf, .word etc.//
​ 	 ​​raise UserError('Please insert a valid file')

Thanks!!

[1] https://self%5C.file_name%5C.endswith
