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:

?

1 2 3 4

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:

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

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：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41

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,

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

<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。
