python - openerp 服务器操作 - python 代码

Question

我不知道我是否应该在这里问这个问题(我现在想也许版主会把它移到 stackoverflow)，但我在 openerp 或 launchpad 论坛上没有得到答案。
在 OpenERP 6.0.1 中，当在发票表单中放置一个按钮以执行它时，以下函数将执行它应该执行的操作:

class account_invoice(osv.osv):
    _inherit = "account.invoice"

    """ Function to update all lines on invoice """
    def update_invoice(self, cr, uid, ids, context=None):
        if context is None:
            context = {}
        line_obj = self.pool.get('account.invoice.line')
        invoice_ids = self.browse(cr, uid, ids, context)
        for invoice in invoice_ids:
            for line in invoice.invoice_line:
                if line.product_id:
                    res = line_obj.product_id_change(cr, uid, [line.id], (line.product_id and line.product_id.id or False), uom=(line.uos_id and line.uos_id.id or False), qty=(line.quantity or 0),
                name=(line.name or ''), type=(invoice.type or False), partner_id=invoice.partner_id.id, fposition_id=invoice.fiscal_position.id, price_unit=(line.price_unit or 0),
                address_invoice_id=(invoice.address_invoice_id and invoice.address_invoice_id.id or False), currency_id=(invoice.currency_id and invoice.currency_id.id or False), context=context)
                    price_unit = res['value']['price_unit']
                    discount = res['value']['discount']
                    line_obj.write(cr, uid, [line.id], {'price_unit': price_unit})
                    line_obj.write(cr, uid, [line.id], {'discount': discount})
        return True

    account_invoice()

也就是说，当在表单中单击此按钮时，发票行的价格单位和折扣会更新。

我正在尝试为“python 代码”类型的对象“发票”创建服务器操作，该操作对菜单项中的所有发票执行此功能。在 python 代码框中，我写道:

inv = self.pool.get('account.invoice')
line_obj = self.pool.get('account.invoice.line')
for invoice in inv.browse(cr, uid, ids):
    for line in invoice.invoice_line:
        res = line_obj.product_id_change(cr, uid, [line.id], (line.product_id and line.product_id.id or False), uom=(line.uos_id and line.uos_id.id or False), qty=(line.quantity or 0), name=(line.name or ''), type=(invoice.type or False), partner_id=invoice.partner_id.id, fposition_id=invoice.fiscal_position.id, price_unit=(line.price_unit or 0), address_invoice_id=(invoice.address_invoice_id and invoice.address_invoice_id.id or False), currency_id=(invoice.currency_id and invoice.currency_id.id or False), context=context)
    price_unit = res['value']['price_unit']
    discount = res['value']['discount']
    line_obj.write(cr, uid, [line.id], {'price_unit': price_unit})
    line_obj.write(cr, uid, [line.id], {'discount': discount})

但它不起作用。我做错了什么？

编辑:谁能帮我写一个函数来更新所有发票行，类似于/account/wizard/account_invoice_state.py 中的行？

Answer 1

如果我想在屏幕中选定的行上运行一些代码，我使用带有 client_action_multi 的向导。这是 a wizard I wrote这只是在选股上设置了一个“健全性检查”标志:

import wizard
import pooler

def _set_flags(self, cr, uid, data, context):
    stock_picking_obj = pooler.get_pool(cr.dbname).get('stock.picking')

    move_ids = data['ids']
    picking_ids = stock_picking_obj.search(
        cr,
        uid,
        [('move_lines', 'in', move_ids)])
    stock_picking_obj.write(cr, uid, picking_ids, {'sanity_checked': True})
    return {}

class sanity_checked(wizard.interface):
    states = {
        'init': {
            'actions': [_set_flags],
            'result': {'type': 'state', 'state':'end'}
        },
    }
sanity_checked('promise.date.sanity.checked')

我configure the wizard使用 client_action_multi 以便它可以在列表中的选定记录上执行:

<wizard
        id="wiz_sanity_checked"
        model="stock.move"
        string="Sanity Checked"
        name="promise.date.sanity.checked"
        keyword="client_action_multi"/>

要实际运行向导，请单击菜单栏中的“操作”按钮。
