I want to create a "Signup/Login Form" by odoo 10.0.
My code python :
class SinhVien(models.Model):   
     _name = "studentmanagement.sinhvien"
     Ten = fields.Char()
     GioiTinh = fields.Char()
     NgaySinh = fields.Char()
     LienLac = fields.Char()
     MatKhau = fields.Char()
     DiaChi = fields.Char()
     DangKyHocPhan = fields.Many2many('studentmanagement.khoahoc', 'Dang_Ky_Hoc_Phan', 'studentmanagement.sinhvien_id', 'studentmanagement.khoahoc_id', string ="dang ky hoc phan")
     _sql_constraints = [ ('LienLac', 'unique(LienLac)', 'Two student with the same user!') ]
     def Log_In(self, Account, Password):
         if Account is not None & Password is not None:
            test_prod_ids = self.search([('LienLac','=',Account),   ('MatKhau','=',Password)], limit=1, context=None)
            return {
              'name': ('My Profile'),
              'view_type': 'form',
              'view_mode': 'form',
              'res_model': 'studentmanagement.sinhvien',
              'view_id': False,
              'type': 'ir.actions.act_window',
            }
        else :
            return None
 class KhoaHoc(models.Model):
       _name = "studentmanagement.khoahoc"
       MonHoc = fields.Char()
       TinChi = fields.Integer()
       PhongHoc = fields.Char()
       GiaoVien = fields.Char()
