Odoo如何为“创建发票”按钮设置用户访问权限组？

Question

I try to assign user access group on Create Invoice Button. However it doesn't work and show these following error msg.

ParseError: "Error while validating constraint

Element '<xpath expr="//button[@name='239'][0]">' cannot be located in parent view

Error context:
View `sale.order.invoice`
[view_id: 547, xml_id: n/a, model: sale.order, parent_id: 509]
None" while parsing /mnt/extra-addons/self-addons/wongnai_flow/views/invoices/create_invoice.xml:3, near
<record model="ir.ui.view">
  <field name="name">sale.order.invoice</field>
  <field name="model">sale.order</field>
  <field name="inherit_id" ref="sale.view_order_form"/>
  <field name="arch" type="xml">
    <xpath expr="//button[@name='%(sale.action_view_sale_advance_payment_inv)d'][0]" position="replace">
      <button name="%(sale.action_view_sale_advance_payment_inv)d" string="Create Invoice" type="action" class="btn-primary" attrs="{'invisible': [('invoice_status', '!=', 'to invoice')]}" groups="wongnai_flow.group_lead"/>
    </xpath>
  </field>
</record>

I don't know what happen. I think my code is already correct.

Do you have any suggestion??

<record model="ir.ui.view">
  <field name="name">sale.order.invoice</field>
  <field name="model">sale.order</field>
  <field name="inherit_id" ref="sale.view_order_form"/>

                    type="action" class="btn-primary"
                    attrs="{'invisible': [('invoice_status', '!=', 'to invoice')]}"
                    groups="wongnai_flow.group_lead"/>

                    attrs="{'invisible': ['|',('invoice_status', '!=', 'no'), ('state', '!=', 'sale')]}"

Answer 1

Your Xpath is not seem be to correct. Please try the following

<xpath expr="//button[@name='%(action_view_sale_advance_payment_inv)d']" position="attributes">
    <attribute name="groups">wongnai_flow.group_lead</attribute>
</xpath>
