Question

我从Odoo Qweb报告开始。我按照本教程创建了第一个自定义报告http://blog.emiprotechnologies.com/create-qweb-report-odoo/

解析器类

import time
from openerp.osv import osv
from openerp.report import report_sxw

class sale_quotation_report(report_sxw.rml_parse):

    def __init__(self, cr, uid, name, context):
        super(sale_quotation_report, self).__init__(cr, uid, name, context=context)
        self.localcontext.update({
                              'time': time,
                              'get_total': self.get_total,
        })

    def get_total(self, lines, field):
        total = 0.0
        for line in lines:
            total += line.product_uom_qty or 0.0
        return total

class report_saleorderqweb(osv.AbstractModel):
    _name = 'sale_report.sale_custom_report_qweb'
    _inherit = 'report.abstract_report'
    _template = 'sale_report.sale_custom_report_qweb'
    _wrapped_report_class = sale_quotation_report

                                             <!--  Print total of product uom qty -->
                                             <strong>
                                                   <span t-esc="get_total(o.order_line)"/>
                                             </strong>

                                 </tr>
                            </tbody>

                  </div>
                </t>
            </t>
        </template>
    </data>
</openerp>

当我打印报告时，它会抛出此错误：

File "/home/user/workspace/lcdv/trunk/server/openerp/tools/safe_eval.py", line 313, in safe_eval
return eval(c, globals_dict, locals_dict)
File "", line 1, in <module>

QWebException: "'NoneType' object is not callable" while evaluating
'get_total(o.order_line)'

Answer 1

我认为你必须把＆＃39; get_total＆＃39;方法进入＆＃39; report_saleorderqweb＆＃39;而不是＆＃39; sale_quotation_report＆＃39;。

Answer 2

检查缩进，因为get_total不属于sale_quotation_report类，如果是，它将抛出以下错误消息：

QWebException: "get_total() takes exactly 3 arguments (2 given)" while evaluating
'get_total(o.order_line)'

您可以在QWEB中计算总数：

<tbody>
    <!-- ** First line ** -->
    <t t-set='total' t-value='0'/>

    <tr t-foreach="o.order_line" t-as="line" style="border-bottom: 1px solid black;">
        <td>
            <span t-field="line.product_id.name"/>
        </td>

        <td>
            <span t-field="line.product_uom_qty"/>
        </td>

        <!-- ** Second line ** -->
        <t t-set='total' t-value='total + line.product_uom_qty'/>

    </tr>

    <tr> 
        <td/>
        <td>
            <!--  Print total of product uom qty -->
            <strong>
                <!-- ** Third line ** -->
                <span t-esc="total"/>
            </strong>
        </td> 
    </tr>
</tbody>

我知道，现在回答已经太迟了，但我希望有人会觉得它有用。

Answer 3

添加此内容

<record id="id_name" 
string="STRING" 
model="model_name" 
name="module_name.template_id"/>

将其添加到xml文件中并调用清单
