我正在尝试创建QWeb报告。我有一个产品清单,我想在同一页上打印每个礼仪。这是我的代码:

<?xml version="1.0" encoding="utf-8"?>
<openerp>
    <data>
        <!-- Déclaration des rapports -->
            <report 
                id="etiquette_produit"
                model="product.template"
                string="Etiquette Produit"
                report_type="qweb-pdf"
                file="Product_Etiquette_QWeb.produit_etiquette"
                name="Product_Etiquette_QWeb.produit_etiquette"
            />

        <template id="produit_etiquette">
            <t t-call="report.external_layout">
                <t t-foreach="docs" t-as="o">
                    <div class="page">
                        <table class="table table-striped">
                            <tr>
                                <td class="col-xs-1"><span t-field="o.default_code"/></td>
                                <td class="col-xs-5 text-center"><span t-field="o.name"/></td>
                                <td class="col-xs-1"><span t-field="o.default_code"/></td>
                                <td class="col-xs-5 text-center"><span t-field="o.name"/></td>
                            </tr>
                            <tr>
                                <td colspan="2" class="text-center">* M E 2 1 5 9 *</td>
                                <td colspan="2" class="text-center">* M E 2 0 1 7 *</td>
                            </tr>
                        </table>
                    </div>
                </t>
            </t>
        </template>
    </data>
</openerp>

问题:当我选择要打印的所有产品时,我有一个错误(见下文)。但是当我只选择一种产品时,我可以打印报告。

Odoo Server Error

有什么想法吗?

答案 0 :(得分:9)

问题与报表引擎期望每页有1个页眉和页脚的事实有关。您正在为1个页眉+页脚创建N页。

调用<t t-call="report.external_layout">必须放在for循环中。如果您在同一页面中需要多个项目,请不要使用page类作为包装器,因为这是引擎用于获取报告页面的内容。您可以查看source code
