Question

所有我知道这需要的不仅仅是时间，但我有太多时间来解决这个问题。

class swiss_customs_invoice_report(report_sxw.rml_parse):

  def __init__(self, cr, uid, name, context):
    super(swiss_customs_invoice_report, self).__init__(cr, uid, name, context)
    self.localcontext.update({

        'get_nw_total':self.get_nw_total,
    })

    self.nw_total=0.0

  def get_nw_total(self):
    return self.nw_total



class swiss_customs_invoice(osv.AbstractModel):
_name = 'report.account_invoice_ept.report_invoice_document_ept_b2c'
_inherit = 'report.abstract_report'
_template = 'account_invoice_ept.report_invoice_document_ept_b2c'
_wrapped_report_class = swiss_customs_invoice_report

这是我的类来描述那个和我的其他XML

    <template id="report_invoice_document_ept_b2c">
        <t t-call="account_invoice_ept.external_layout_ept_b2c">

                            t-field-options='{"widget": "contact", "fields": ["address", "name","phone","mobile"], "no_marker": true}' />
                        <span t-if="o.partner_id.vat">
                            TIN:

                        </span>
                    </div>
                </div>                  

                <div>
                    <div class="col-xs-2">

                    </div>
                </div>
            </div>

            </t>
        </t>
    </template>


    <report id="report_action_invoice_ept_b2c" string="Swiss Customs Invoice"

那么如何解决这个问题和所有时间给我的错误是NoneType＆＃39;对象不可调用＆＃34;同时评估和使用

o.get_nw_total（） docs.get_nw_total（）

堆栈中的其他所有灵魂。

Qweb报告错误无类型＆＃39;对象不可调用＆＃34;在评估时
