python - 如何隐藏按钮 "Create invoice"但基于条件？ (奥杜11)

Question

我确实被阻止了，我想隐藏“创建发票”按钮，但基于一个条件，我的条件是如果订单行有服务，则该按钮被隐藏。我创建了一个字段和一个函数，但最终总是出现模型中不存在该字段的错误，这是我的代码:

错误:

Field 'hide_invoice' used in attributes must be present in view but is missing

我的领域和职能(Python):

from odoo import api, fields, models,_


class SaleOrder(models.Model):
    _inherit = 'sale.order'

    hide_invoice = fields.Boolean(compute="_hide_button_invoice", string="",)


    @api.multi
    @api.depends('tasks_count')
    def _hide_button_invoice(self):
        for order in self:
            if order.tasks_count > 0:
                order.hide_invoice = True
            elif order.tasks_count == 0:
                order.hide_invoice = False 

我的 XML(我在表单上看到它有效):

<odoo>
<record id="button_invoice_view_form" model="ir.ui.view">
        <field name="name">sale.order.button.create.form</field>
        <field name="model">sale.order</field>
        <field name="inherit_id" ref="sale.view_order_form"/>
        <field name="arch" type="xml">
            <xpath expr="//field[@name='partner_id']" position="before">
                <field name ="hide_invoice"/>
            </xpath>
        </field>
</record>
</odoo>

然后我想隐藏它的按钮:

<record id="sale_order_view_form" model="ir.ui.view">
    <field name="name">sale.order.form</field>
    <field name="model">sale.order</field>
    <field name="inherit_id" ref="sale.view_order_form"/>
    <field name="arch" type="xml">
        <xpath expr="//group[@name='sale_pay']/field[@name='invoice_status']" position="attributes">
            <attribute name="invisible" eval="False"/>
        </xpath>
        <xpath expr="//button[@name='action_quotation_send']" position="before">
            <button name="%(sale.action_view_sale_advance_payment_inv)d" string="Create Invoice"
                type="action" class="btn-primary"
                attrs="{'invisible': [('invoice_status', '!=', 'to invoice')]}"/>
            <button name="%(sale.action_view_sale_advance_payment_inv)d" string="Create Invoice"
                type="action" context="{'default_advance_payment_method': 'percentage'}"
                attrs="{'invisible': ['|','|',('hide_invoice', '=', True),('invoice_status', '!=', 'no'), ('state', '!=', 'sale')]}"/>
        </xpath>
    </field>
</record>

Answer 1

您必须在标题级别显示字段才能处理这些。

就像在声明按钮之前执行以下代码一样。

<field name='hide_invoice' invisible='1'/>

并将其删除在partner_id字段之前。

您可以尝试使用以下 xml 代码吗:

<record id="sale_order_view_form" model="ir.ui.view">
    <field name="name">sale.order.form</field>
    <field name="model">sale.order</field>
    <field name="inherit_id" ref="sale.view_order_form"/>
    <field name="arch" type="xml">
        <xpath expr="//group[@name='sale_pay']/field[@name='invoice_status']" position="attributes">
            <attribute name="invisible" eval="False"/>
        </xpath>
        <xpath expr="//button[@name='action_quotation_send']" position="before">
            <button name="%(sale.action_view_sale_advance_payment_inv)d" string="Create Invoice"
                type="action" class="btn-primary"
                attrs="{'invisible': [('invoice_status', '!=', 'to invoice')]}"/>
            <field name="hide_invoice" invisible="1"/>
            <button name="%(sale.action_view_sale_advance_payment_inv)d" string="Create Invoice"
                type="action" context="{'default_advance_payment_method': 'percentage'}"
                attrs="{'invisible': ['|','|',('hide_invoice', '=', True),('invoice_status', '!=', 'no'), ('state', '!=', 'sale')]}"/>
        </xpath>
    </field>
</record>
