openerp服務器動作 - 蟒蛇代碼

Question

我不知道我是否應該問這裏（即時通訊現在想也許一個版主會將它移動到stackoverflow），但即時通訊沒有得到在openerp或launchpad論壇上的答案。
在OpenERP的6.0.1，下面的函數做什麼它應該做的，當一個按鈕被放置在發票的形式來執行它：

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() 

這是說，發票行價格單位和折扣在表單中單擊此按鈕時更新。

即時嘗試創建一個類型爲「python代碼」的對象「發票」的服務器操作，該操作在菜單項的所有發票上執行此功能。在Python代碼框中，我寫道：

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。我究竟做錯了什麼？

編輯： 誰能幫我寫一個更新功能的所有發票行類似於/account/wizard/account_invoice_state.py？

我設法成功地寫什麼我需要的，那就是：

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()

在服務器操作中，您可以編寫簡單的Python代碼..您正試圖使用​​self.pool.get（）。它不可能從服務器action.And請具體說明您的要求

Answer 3

如果我想在屏幕上選定的行上運行一些代碼，我使用嚮導client_action_multi。下面是a wizard I wrote，只是設置一個「健全檢查」標誌股票採摘：

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與client_action_multi，因此它可以對選定的記錄顯示在列表中執行：

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

要實際運行嚮導中，單擊菜單欄中的「操作」按鈕。
