Question

我正在修改Purchase模块以在采购订单行中添加新字段。我已成功添加代码以创建模型并查看自定义字段。但是无法将自定义字段添加到P.O.的总金额中。线。

class customPo(osv.osv):

    _inherit="purchase.order"
    #_name = 'customPo'

    def _amount_all(self, cr, uid, ids, field_name, arg, context=None):
        res = {}
        cur_obj=self.pool.get('res.currency')
        for order in self.browse(cr, uid, ids, context=context):
            res[order.id] = {
                'amount_untaxed': 0.0,
                'amount_tax': 0.0,
                'amount_total': 0.0,
            }
            val = val1 = 0.0
            cur = order.pricelist_id.currency_id
            for line in order.order_line:
               # val1 += line.price_subtotal
               val1 = val1 + line.data + line.price_subtotal
               for c in self.pool.get('account.tax').compute_all(cr, uid, line.taxes_id, line.price_unit, line.product_qty, line.product_id, order.partner_id)['taxes']:
                    val += c.get('amount', 0.0)
            res[order.id]['amount_tax']=cur_obj.round(cr, uid, cur, 42.0)
            res[order.id]['amount_untaxed']=cur_obj.round(cr, uid, cur, val1)
            res[order.id]['amount_total']=res[order.id]['amount_untaxed'] + res[order.id]['amount_tax']
        return res

        _columns = {
            'order_line': fields.one2many('purchase.order.line', 'order_id', 'Order Lines', states={'approved':[('readonly',True)],'done':[('readonly',True)]}),
            'amount_untaxed': fields.function(_amount_all, digits_compute= dp.get_precision('Account'), string='Untaxed Amount',
                store={
                    'purchase.order.line': (_get_order, None, 10),
                }, multi="sums", help="The amount without tax", track_visibility='always'),
            'amount_tax': fields.function(_amount_all, digits_compute= dp.get_precision('Account'), string='Taxes',
                store={
                    'purchase.order.line': (_get_order, None, 10),
                }, multi="sums", help="The tax amount"),
            'amount_total': fields.function(_amount_all, digits_compute= dp.get_precision('Account'), string='Total',
                store={
                    'purchase.order.line': (_get_order, None, 10),
                }, multi="sums",help="The total amount"),
        }
customPo()

class customPol(osv.osv):
    _inherit = 'purchase.order.line'
    # _name = 'something.notpurchase'
    _columns = {
        'data': fields.float('Unit Price', required=True, digits_compute= dp.get_precision('Product Price')),
    }

customPol()

我保持税收静态为42所以，我可以知道何时调用被覆盖的方法但它永远不会发生。

我的观看文件如下。

<?xml version="1.0" encoding="utf-8"?>
<openerp>
<data>
        <record id="custom_purchse_wa" model="ir.ui.view">
            <field name="name">Custom Field New</field>
            <field name="model">purchase.order</field>
            <field name="inherit_id" ref="purchase.purchase_order_form"/>
            <field name="arch" type="xml">
                <xpath expr="/form/sheet/notebook/page/field[@name='order_line']/tree/field[@name='price_unit']" position="after">
                <field name="data" string="Custom field"/>
                </xpath>
            </field>

Answer 1

您必须覆盖

 _amount_line

在purchase.order.line类中的功能所以你可以计算金额

自定义OpenERP模块无法正常工作
