python - Odoo Onchange 方法不更新选择字段

Question

我在员工和部门表单中有两个选择框字段。我想根据员工的department_id选择员工时自动选择部门。

这是我的 .py 代码 (Odoo 11)

class HrExpenseExpense(models.Model):
_inherit = "hr.expense"

department_expense_group = fields.Selection(
    string='Department Expense Group',
    related='department_id.expense_group',
    readonly=True,
)
department_id = fields.Many2one('hr.department', string='Department',
                                states={'post': [('readonly', True)], 'done': [('readonly', True)]})

@api.onchange('employee_id')
def onchange_employee_id(self):
    department_id = [x.id for x in self.employee_id.department_id]
    return {'domain': {'department_id': [('id', 'in', department_id)]}}

和xml View 文件:

 <xpath expr="//field[@name='employee_id']" position="after">
   <field name="department_expense_group" invisible="1" />
   <field name="department_id" invisible="0"/>
 </xpath>

它可以工作，但问题是这样的；当我选择员工时，部门选择框自动更新，它会触发但不会自动选择。单击后，选择框的列表将被填充。必须根据员工的选择自动选择。

您只需更改字段 department_id 的过滤器，并且必须自行设置它以满足您的要求。并且您正在循环单个记录字段(employee_id.department_id)，这在这里有点夸张。

@api.onchange('employee_id')
def onchange_employee_id(self):
    if self.employee_id:
        department = self.employee_id.department_id
        # set department
        self.department_id = department
        # don't allow other departments
        return {'domain': {'department_id': [('id', '=', department.id)]}}
    else:
        # empty department
        self.department_id = False
        # allow other departments
        return {'domain': {'department_id': [('id', '!=', False)]}}
