库存明细报表的实现

qdfulee

OE当前的功能里，查询库存要么是所有产品所有库位一张表，要么是一个产品在不同库位的数量分布，无法在一张表上实现多个产品多个库位的明细。
于是就有了如下的代码：

# -*- coding: utf-8 -*-<br />from openerp.osv import osv,fields<br />from lxml import etree<br />from openerp import tools<br /><br /><br />class product_product(osv.osv):<br />&nbsp; &nbsp; _inherit = &quot;product.product&quot;<br /><br />&nbsp; &nbsp; def fields_view_get(self, cr, uid, view_id=None, view_type=&#039;form&#039;, context=None, toolbar=False, submenu=False):<br />&nbsp; &nbsp; &nbsp; &nbsp; res = super(product_product, self).fields_view_get(cr, uid, view_id, view_type, context, toolbar=toolbar, submenu=submenu)<br />&nbsp; &nbsp; &nbsp; &nbsp; if context.get(&#039;inventory_list&#039;) == True and view_type == &#039;tree&#039;:<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; loc_obj = self.pool.get(&#039;stock.location&#039;)<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; locations = loc_obj.browse(cr, uid, loc_obj.search(cr, uid, [(&#039;child_ids&#039;, &#039;=&#039;, False), (&#039;usage&#039;, &#039;=&#039;, &#039;internal&#039;)]))<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; view = etree.fromstring(res&#91;&#039;arch&#039;])<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; fields_list = res&#91;&#039;fields&#039;]<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; for location in locations:<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; fields_list[tools.ustr(location.id)+&#039;-real&#039;] = {&#039;type&#039;: &#039;float&#039;, &#039;string&#039;: location.name+&#039;-实际库存&#039;}<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; fields_list[tools.ustr(location.id)+&#039;-virtual&#039;] = {&#039;type&#039;: &#039;float&#039;, &#039;string&#039;: location.name+&#039;-账面库存&#039;}<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; etree.SubElement(view, &#039;field&#039;, {&#039;name&#039;: tools.ustr(location.id)+&#039;-real&#039;})<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; etree.SubElement(view, &#039;field&#039;, {&#039;name&#039;: tools.ustr(location.id)+&#039;-virtual&#039;})<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; res&#91;&#039;arch&#039;] = etree.tostring(view)<br />&nbsp; &nbsp; &nbsp; &nbsp; return res<br /><br />&nbsp; &nbsp; def read(self, cr, uid, ids, fields=None, context=None, load=&#039;_classic_read&#039;):<br />&nbsp; &nbsp; &nbsp; &nbsp; result = super(product_product, self).read(cr, uid, ids, fields=fields, context=context)<br />&nbsp; &nbsp; &nbsp; &nbsp; if context.get(&#039;inventory_list&#039;) == True:<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; locations = &#91;]<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; for field in fields:<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; s = field.split(&#039;-&#039;)<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if len(s) == 2:<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if s[1] == &#039;real&#039;:<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; locations.append(int(s[0]))<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; i = 0<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; for id in ids:<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; for location in locations:<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; context&#91;&#039;location&#039;] = location<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; val = super(product_product, self).read(cr, uid, id, &#91;&#039;qty_available&#039;, &#039;virtual_available&#039;], context, )<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; result[i][tools.ustr(location)+&#039;-real&#039;] = val&#91;&#039;qty_available&#039;]<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; result[i][tools.ustr(location)+&#039;-virtual&#039;] = val&#91;&#039;virtual_available&#039;]<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; i += 1<br />&nbsp; &nbsp; &nbsp; &nbsp; return result

这个是怎么用啊。。没看懂

能否讲解下怎么用呢

后台代码在附件中。说明下，前台显示的二级表头不是我做的，不能上传，见谅。
目前这个版本的效率不高，希望高手能优化下。

模块设计思路：

1、库存明细表是通过 fields_view_get 动态生成的。
2、不同库位的库存根据系统stock里product.product 中的字段 qty_available，virtual_available 读出。这两个字段的值是依据context里不同库位读出。我是通过这个功能循环产品id和库位id读出的。（这个方法挺笨的）
3、功能入口通过向导进入。向导生成的菜单如下图：
[attachimg=2]

如果安装出错，可能需要把 product.py里 fields_view_get（）中下几句代码：
etree.SubElement(view, 'field', {'name': tools.ustr(location.id)+'-real', 'th_string':location.name, 'colspan':'2'})
etree.SubElement(view, 'field', {'name': tools.ustr(location.id)+'-virtual','colspan':'1'})
etree.SubElement(view, 'field', {'name': 'qty_available', 'string': u'实际库存', 'th_string': u'汇总', 'colspan':'2'})
etree.SubElement(view, 'field', {'name': 'virtual_available', 'string': u'账面库存', 'colspan':'1'})
中的'th_string' 和'colspan' 标签去掉。
