OpenERP v7 报告错误

Question

我添加了一个关于stock 模块的新报告（到 OpenERP v7 中），但是 rml 文件的路径对我来说似乎是正确的，当单击“打印”按钮时它显示：

RML is not available at specified location or not enough data to print!

(None, None, None)

应该是我在 .py 文件上指定的路径有错误，但我检查了又重新检查，似乎是正确的。

这是我的代码：

import time
from openerp.report import report_sxw

class reporte_locacion(report_sxw.rml_parse):
    def __init__(self, cr, uid, name, context):
        super(reporte_locacion, self).__init__(cr, uid, name, context=context)
        self.localcontext.update({
             'time': time,
             'qty_total':self._qty_total
        })

def _qty_total(self, objects):
    total = 0.0
    uom = objects[0].product_uom.name
    for obj in objects:
        total += obj.product_qty
    return {'quantity':total,'uom':uom}

report_sxw.report_sxw(
    'report.reporte.locacion',
    'product.product',
    'addons/stock/report/reporte_locacion.rml',
    parser=reporte_locacion,
    header='internal'
)

我已经在那个位置有它，它可以是stock_report.xml 文件吗？

我是这样声明报告的：

<?xml version="1.0" encoding="utf-8"?>
<openerp>
    <data>
        <report auto="False" id="reporte_locacion" model="product.product" name="reporte.locacion" string="Productos en almacen"/>
        <report auto="False" id="report_product_history" model="product.product" name="stock.product.history" string="Stock Level Forecast"/>
        <report id="report_picking_list" model="stock.picking" name="stock.picking.list" string="Picking Slip" rml="stock/report/picking.rml"/>
        <report id="report_picking_list_in" model="stock.picking.in" name="stock.picking.list.in" string="Receipt Slip" rml="stock/report/picking.rml"/>
        <report id="report_picking_list_out" model="stock.picking.out" name="stock.picking.list.out" string="Delivery Slip" rml="stock/report/picking.rml"/>
        <report id="report_move_labels" model="stock.move" name="stock.move.label" string="Item Labels" xml="stock/report/lot_move_label.xml" xsl="stock/report/lot_move_label.xsl"/>
        <report auto="False"  id="report_location_overview" model="stock.location" name="lot.stock.overview" string="Location Inventory Overview" rml="stock/report/lot_overview.rml"/>
        <report id="report_location_overview_all" model="stock.location" name="lot.stock.overview_all" string="Location Content" rml="stock/report/lot_overview_all.rml"/>
        <report id="report_stock_inventory_move" model="stock.inventory" name="stock.inventory.move" string="Stock Inventory" rml="stock/report/stock_inventory_move.rml"/>
    </data>
</openerp>

关于它的第一个报告是有错误的，我错过了什么吗？

应该没问题，因为它的声明类型与其他报告几乎相同，但它们都可以正常工作。

有什么想法吗？

提前致谢！

声明应该是这样的

<report id="reporte_locacion" 
        model="product.product" 
        name="reporte.locacion" 
        string="Productos en almacen" 
        rml="addons/stock/report/reporte_locacion.rml"/>
