我正在尝试创建自定义报告，我遵循了在Odoo github上找到的一些代码，但是它不起作用。
首先，我正在创建一个具有获取我的数据并将其放入python dict的函数的transiant模型：
// see UserService.java => auto-activate newUser
// mailService.sendActivationEmail(user);
接下来我要在view.xml文件中创建一个报告对象：
from odoo import api, fields, models
import logging
_logger = logging.getLogger(__name__)
class SockValuationReport(models.TransientModel):
_name = 'report.stock_valuation_flora'
_description = 'Sotck valuation report for floravert'
@api.multi
def render_report(self):
products = self.env['product.template'].search([])
data = {}
categ_dict = {}
for product in products:
valuation = 0
if(product.categ_id.name in categ_dict):
valuation = product.standard_price * product.qty_available
categ_dict[product.categ_id.name]['valuation'] = categ_dict[product.categ_id.name]['valuation'] + valuation
else:
categ_dict[product.categ_id.name] = {'categ_name':product.categ_id.name, 'valuation':product.standard_price * product.qty_available}
data['products'] = products
data['categ_value']= categ_dict
_logger.info(data)
return self.env.ref('stock_printer.report_stock_product_valuation').report_action(self,data=data)
然后我要添加视图模板：
<report
id="report_stock_product_valuation"
model="report.stock_valuation_flora"
string="Stock Report"
report_type="qweb-pdf"
name="stock_printer.report_stock_valuation"
file="stock_printer.report_stock_valuation"/>
但是当我尝试打印此报告时，出现此错误：
<template id="report_stock_valuation">
<t t-call="web.html_container">
<t t-call="web.internal_layout">
<div class="page">
<h1>MY REPORT</h1>
<table style="border-spacing:0;margin-bottom:0;" class="table">
<thead>
<tr>
</tr>
</thead>
<tbody>
<t t-foreach="data['products']" t-as="product">
<span t-esc="product.name" />
</t>
</tbody>
</table>
</div>
</t>
</t>
</template>
好像我的数据不会进入我的视图，但是当我在将数据发送到视图之前记录我的数据时，我有一个具有我想要的值的字典：

所以我一直在努力使它工作4个小时，但实际上我有点迷失了，如果有人知道如何解决这个问题，我会很高兴的
谢谢
编辑：
好吧，我终于设法使它生效，我遵循了销售明细报表的方法，并且我已经完成了一个抽象模型，该模型可以获取我的数据并将其提供给我的视图，
我仍然有点迷茫，为什么它以前不起作用，但现在起作用了
