ODOO 11技术问询：订单行含任务/服务时隐藏Invoice Order按钮

Hey there! Absolutely, you can pull this off in Odoo 11 using either Python (for custom, flexible logic) or XML (direct view-based conditional visibility). Let's break both approaches down for you:

Method 1: Python + XML (Recommended for Most Cases) #

This approach uses a computed field to check if any order line has a service or task, then ties that field to the button's visibility in the view.

Step 1: Add the Computed Field in Python #

In your custom module's models folder, create or update the sale order inheritance file:

from odoo import models, fields, api

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

    has_service_task = fields.Boolean(
        string="Has Service/Task Line",
        compute='_compute_has_service_task',
        store=False,  # No need to store since it's dynamic
        readonly=True
    )

    @api.depends('order_line')
    def _compute_has_service_task(self):
        for order in self:
            # Adjust this condition to match your exact business rule
            # Example 1: Check if any line has a service-type product
            # has_service = any(line.product_id.type == 'service' for line in order.order_line)
            # Example 2: Check if any line is linked to a task (e.g., via task_id)
            # has_task = any(line.task_id for line in order.order_line)
            # Combine both if needed:
            order.has_service_task = any(
                line.product_id.type == 'service' or line.task_id
                for line in order.order_line
            )

Step 2: Update the View to Hide the Button #

In your custom module's views folder, add an inheritance view for the sale order form:

<odoo>
    <record id="sale_order_form_inherit_hide_invoice_button" model="ir.ui.view">
        <field name="name">sale.order.form.inherit.hide.invoice.button</field>
        <field name="model">sale.order</field>
        <field name="inherit_id" ref="sale.view_order_form"/>
        <field name="arch" type="xml">
            <!-- Target the "Invoice Order" button by its action name -->
            <xpath expr="//button[@name='action_invoice_create']" position="attributes">
                <!-- Hide the button when has_service_task is True -->
                <attribute name="attrs">{'invisible': [('has_service_task', '=', True)]}</attribute>
            </xpath>
        </field>
    </record>
</odoo>

Method 2: Pure XML (Simpler for Basic Conditions) #

If your condition is straightforward (like checking for service-type products), you can skip the Python field and directly use a domain in the view's attrs:

<odoo>
    <record id="sale_order_form_inherit_hide_invoice_button_xml" model="ir.ui.view">
        <field name="name">sale.order.form.inherit.hide.invoice.button.xml</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='action_invoice_create']" position="attributes">
                <!-- Hide if any order line has a service product -->
                <attribute name="attrs">
                    {'invisible': [('order_line', '!=', False), ('order_line.product_id.type', '=', 'service')]}
                </attribute>
            </xpath>
        </field>
    </record>
</odoo>

Note: This method works for simple one-line conditions but is less flexible for complex logic (like combining multiple checks for tasks and services).

Quick Tips #

• Double-check the button's name attribute in your Odoo 11 instance (it's action_invoice_create for the default "Invoice Order" button)
• Adjust the condition logic to match your exact definition of "has task/service" (e.g., if tasks are linked via a custom field instead of task_id, update that part)
• Remember to update your module's __manifest__.py to include the new model and view files, then upgrade the module to apply changes.

Let me know if you need help tweaking the logic to fit your specific workflow!
