以继承形式Odoo向按钮添加属性

Question

我想查看基于布尔字段（基于功能）的按钮（从继承的表单），以使员工经理能够批准或拒绝员工的请假请求

views.xml

<record id="manager_approve_refuse_his_employees_leaves" model="ir.ui.view">
  <field name="name">Manager Approve Refuse His Employees Leaves</field>
  <field name="model">hr.holidays</field>
  <field name="inherit_id" ref="hr_holidays.edit_holiday_new"/>
  <field name="arch" type="xml">
    <xpath expr="//field[@name='state']" position="before">
      <field name="view_leaves" invisible="0"/>
    </xpath>
    <xpath expr="//button[@name='action_approve']" position="attributes">
      <attribute name="attrs">{'invisible': [('view_leaves' ,'=', False)]}</attribute>
    </xpath>
  </field>
</record>

models.py

class InheritHrHolidays(models.Model):
    _inherit = 'hr.holidays'

    view_leaves = fields.Boolean(compute="view_leaves_for_manager", store=False)
    @api.multi
    def view_leaves_for_manager(self):
        if self.env.uid == self.employee_id.parent_id.user_id.id:
            self.view_leaves = True

这是原始按钮

<button string="Approve" name="action_approve" states="confirm" type="object" groups="hr_holidays.group_hr_holidays_user" class="oe_highlight"/>

但是按钮尚未出现..有什么问题

Answer 1

在这种情况下，您首先要从按钮中删除“状态”属性，然后添加“属性”属性。例如：

<xpath expr="//button[@name='action_approve']" position="attributes">
    <attribute name="states"/>
    <attribute name="groups"/>
    <attribute name="attrs">{'invisible': [('view_leaves' ,'=', False)]}</attribute>
</xpath>

之后，重新启动服务器和升级模块。
