Câu hỏi của tôi là, làm cách nào tôi có thể tìm thấy phần mở rộng tệp từ chuỗi nhị phân này?

câu trả lời hay nhất

Cuối cùng đã tìm ra giải pháp:

*.py

file = field.Binary('File')
file_fname = field.Char(string='Tên tệp')

*.xml

Tên tập tin sẽ được lưu trong tên_tệptrong lĩnh vực này.

并使用 chia nhỏPhương thức trích xuất phần mở rộng từ tên tệp.

@api.onchange('file')
@api.depends('file','file_fname')
def check_file_type(tự):
    nếu self.file:
        tên tệp,filetype = os.path.splitext(self.file_fname)
        nếu loại tệp không có trong ['.xls','.csv']:
            raise UserError(_('Loại tệp không hợp lệ!!!\n Chọn định dạng tệp excel hoặc csv.'))

Về python - nhận loại tệp/phần mở rộng từ dữ liệu nhị phân, chúng tôi đã tìm thấy một câu hỏi tương tự trên Stack Overflow: https://stackoverflow.com/questions/45136896/
