Docx 文档没有生成 python-docx

Question

最重要的是，html代码中有一个表单询问将从数据库中获取什么时期的记录。 当您单击“生成”按钮时，应该会生成一个 docx 文档。但是由于某种原因没有生成，选择成功，没有报错。 html

<form action="" method="get" class="my-4 ">
    <input type="date" name="date_from" value="{{ date_from }}" id="date_from">
    <input type="date" name="date_until" value="{{ date_until }}" id="date_until">
    <input type="submit" value="Generate" class="btn btn-primary">
</form>

收集了该期间的数据，但由于某种原因根本没有创建报告文件... 在我看来，我错误地引用了“记录”对象，但我不明白如何正确地做到这一点。

模型.py

class OrderStorage(models.Model):
    user = models.ForeignKey(to=User, verbose_name='User', on_delete=models.CASCADE)
    size = models.ForeignKey(verbose_name='Size', to=TireSize, on_delete=models.CASCADE)
    status = models.IntegerField(verbose_name='Status', choices=OrderStatus.choices, default=0)
    created_at = models.DateTimeField(verbose_name='Create at', auto_now_add=True)
    updated_at = models.DateTimeField(verbose_name='Update at', auto_now=True)

点击“生成”后。正在填写 docx 文件
