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将其移至 stackoverflow），但我在 openerp 或启动板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来执行它时，以下函数会执行它应该做的事情：

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，会更新发票行的价格单位和折扣。

我正在尝试为“python 代码”类型的对象“发票”创建一个服务器操作，该操作在菜单项的所有发票上执行此功能。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： 谁能帮我写一个更新所有发票行的函数，类似于 /account/wizard/account_invoice_state.py 中的那些？

如果我想在屏幕中的选定行上运行一些代码，我使用带有client_action_multi 的向导。这是a wizard I wrote，它只是在选股时设置了一个“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')

我将configure the wizard 与client_action_multi 结合起来，这样就可以对列表中的选定记录执行：

<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。

在服务器操作中，您可以编写简单的 python 代码。您正在尝试使用 self.pool.get()。服务器操作不可能。请具体说明您的要求

我成功地写了我需要的东西，这里是：

class account_invoice_update(osv.osv_memory):

_name = "account.invoice.update"

""" Function to update all lines on selected invoice(s) """
def invoice_update(self, cr, uid, ids, context=None):
    if context is None:
        context = {}

    pool_obj = pooler.get_pool(cr.dbname)
    data_inv = pool_obj.get('account.invoice').read(cr, uid, context['active_ids'], ['state'], context=context)

    for record in data_inv:
        if record['state'] in ('cancel','paid','open'):
            raise osv.except_osv(_('Warning'), _("Selected Invoice(s) cannot be cancelled as they are already in 'Cancelled','Done', or 'Open' state!"))

    inv_obj = self.pool.get('account.invoice')
    inv_line_obj = self.pool.get('account.invoice.line')
    for invoice in inv_obj.browse(cr, uid, context.get('active_ids'), context=context):
        for line in invoice.invoice_line:
            res = inv_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']
            inv_line_obj.write(cr, uid, [line.id], {'price_unit': price_unit})
            inv_line_obj.write(cr, uid, [line.id], {'discount': discount})

    return {'type': 'ir.actions.act_window_close'}

account_invoice_update()
