Odoo 条码扫码功能

采购订单、销售订单通过扫码增加明细

        很多人都说从9.0 之后,很多社区版功能被阉割了,比如大家常说的仓库条码扫码模块就没有了。 但是却为我们留下了bcarcode模块,方便我们进行扩展。
        由于有需求,需要为采购模块增加条码扫码功能,代码如下:
        1.需要在purchase.order.line 增加product_barcode字段,关联自产品资料的bcarcode:
        class PurchaseOrderLine(models.Model):
        _inherit = 'purchase.order.line'

        product_barcode = fields.Char(related='product_id.barcode')
        2.在purchase.order.line 增加一个方法on_barcode_scanned,获取扫描枪获取的条码,同时继承扩展barcodes.barcode_events_mixin,代码如下:
        class PurchaseOrder(models.Model):
        _name = 'purchase.order'
        _inherit = ['purchase.order', 'barcodes.barcode_events_mixin']

        def _add_product(self, product, qty=1.0):
        order_line = self.order_line.filtered(lambda r: r.product_id.id == product.id)
        if order_line:
        order_line.product_qty = qty
        else:
        product_lang = product.with_context({
        'lang': self.partner_id.lang,
        'partner_id': self.partner_id.id,
        })
        name = product_lang.display_name
        if product_lang.description_purchase:
        name += '\n' + product_lang.description_purchase

        vals = {
        'product_id': product.id,
        'name': name,
        'date_planned': fields.Datetime.now(),
        'product_uom': product.uom_po_id.id,
        'product_qty': 1,
        'price_unit': product.standard_price,
        'state': 'draft',
        }

        self.order_line += self.order_line.new(vals)

        def on_barcode_scanned(self, barcode):
        product = self.env['product.product'].search([('barcode', '=', barcode)])
        if product:
        self._add_product(product)
        3.增加js代码,使得前端获取条码:
        odoo.define('purchase_barcode.PurchaseOrderBarcodeHandler', function (require) {
        "use strict";

        var field_registry = require('web.field_registry');
        var AbstractField = require('web.AbstractField');
        var FormController = require('web.FormController');

        FormController.include({
        _barcodePurchaseAddRecordId: function (barcode, activeBarcode) {
        if (!activeBarcode.handle) {
        return $.Deferred().reject();
        }
        var record = this.model.get(activeBarcode.handle);
        if (record.data.state != 'draft') {
        this.do_warn("采购订单", '只能对草稿状态的单据增加明细');
        return $.Deferred().reject();
        }
        return this._barcodeAddX2MQuantity(barcode, activeBarcode);
        }
        })

        var PurchaseOrderBarcodeHandler = AbstractField.extend({
        init: function () {
        this._super.apply(this, arguments);

        this.trigger_up('activeBarcode', {
        name: this.name,
        fieldName: 'order_line',
        quantity: 'product_qty',
        setQuantityWithKeypress: true,
        commands: {
        // 'O-CMD.MAIN-MENU': _.bind(this.do_action, this, 'stock_barcode.stock_barcode_action_main_menu', {clear_breadcrumbs: true}),
        barcode: '_barcodePurchaseAddRecordId',
        }
        });
        },
        });

        field_registry.add('purchaseorder_barcode_handler', PurchaseOrderBarcodeHandler);

        });
        4.扩展purchase order view 部分,
        <record id="view_purchase_order_barcode_inherit_form" model="ir.ui.view">
        <field name="name">purchase.order.form</field>
        <field name="model">purchase.order</field>
        <field name="inherit_id" ref="purchase.purchase_order_form"/>
        <field name="priority" eval="8"/>
        <field name="arch" type="xml">
        <form position="inside">
        <field name="_barcode_scanned" widget="purchaseorder_barcode_handler"/>
        </form>

        <xpath expr="//field[@name='order_line']/tree" position="inside">
        <field name="product_barcode" invisible="1"/>
        </xpath>
        <xpath expr="//field[@name='order_line']/kanban" position="inside">
        <field name="product_barcode" invisible="1"/>
        </xpath>
        <xpath expr="//field[@name='order_line']//field[@name='product_qty']" position="attributes">
        <attribute name="options">{'barcode_events': True}</attribute>
        <attribute name="widget">field_float_scannable</attribute>
        </xpath>
        <xpath expr="//button[@name='button_confirm']" position="attributes">
        <attribute name="barcode_trigger">validate</attribute>
        </xpath>
        </field>
        </record>

        这样,就可以在界面上直接用扫描枪扫码增加订单明细了。
