尝试在 Odoo 中运行 mako 模板时出现 Jinja 错误

Question

当我尝试运行这个用 mako 模板编写的报告时出现此错误：

Encountered unknown tag 'total_price'. Jinja was looking for the following tags: 'endfor' or 'else'. The innermost block that needs to be closed is 'for'.

<class 'jinja2.exceptions.TemplateSyntaxError'>,Encountered unknown tag 'total_price'. Jinja was looking for the following tags: 'endfor' or 'else'. The innermost block that needs to be closed is 'for'.,<traceback object at 0x02F2F490>

在 openerp 7 中运行良好，但在 odoo 8 中无法运行。

                <% total_price = 0.0 %>
                %for line_container_ids in shipping.container_line_ids:
                    <%
                        total_price = line_container_ids.product_qty * line_container_ids.net_price
                        curr = line_container_ids.currency_id.name
                    %>
                % endfor

Answer 1

从 Odoo V8 开始，您需要更改使用的语法，而使用 jinja2 似乎很难做到这一点。下面是在 Odoo V9 中使用销售订单测试的示例：

% set total_price = []
% for line in object.order_line:
    % if total_price.append(line.price_subtotal)
    % endif
% endfor
${sum(total_price)}
