我对hr.employee.public型号有问题.如果我try 添加新字段Char、Buttons、Many 2one等，我没有任何问题.
然而，如果我try 插入这样的二进制字段employee_signature = fields.Binary(string='Employee signature', attachment=True, store=True)，我总是会得到以下错误:
psycopg2.errors.UndefinedColumn: column emp.employee_signature does not exist
LINE 3: ...l,emp.priv_email,emp.employee_file_name_signature,emp.employ...
我哪里错了？可能是什么问题？
如果您继承hr.employee.public来添加stored field(而不是x2many个字段)，您应该会看到相同的错误消息，因为init function试图从hr.employee获取字段
您不需要将store属性设置为True，因为这是默认值(如果将store设置为False，则可能无法保存附件).
当attachment属性设置为True(默认值)时，Odoo会设置column type of the field to None和ignore updating the database schema
要解决此问题，您可以使用与扩展Binary字段image_1920字段相同的逻辑

class HrEmployee(models.Model):
_inherit = 'hr.employee'
employee_signature = fields.Binary(string='Employee signaturez', attachment=False)
class HREmployeePublic(models.Model):
_inherit = "hr.employee.public"
employee_signature = fields.Binary(compute="_compute_employee_signature", compute_sudo=True)
def _compute_employee_signature(self):
for employee in self:
employee_id = self.sudo().env['hr.employee'].browse(employee.id)
employee.employee_signature = employee_id.employee_signature
