昨天我想在{{}}中使用nest {{..}}时遇到错误，变量data是一个列表。
“data.append（{'month'：month，'loan_type'：data_type，'channel'：data_channel}）”。 data_type和data_channel是字典。在我的'.tmpl'文件中，我传输了两个变量：data和title_data，title_data也是一个列表，它代表data.data_type和{{的字段名称1}}。
在我的data.data_channel文件中，我希望遍历.tmpl以显示数据。
title_data但它引发了一个错误：
{% for record in data %}
<tr>
<td rowspan="14">record.month</td>
<td rowspan="7">loan_angel</td>
</tr>
<tr>
<td rowspan="7">loan_flow</td>
</tr>
<tr>
<td>loan_angel</td>
{% for title in title_data %}
<td>{{ record.loan_type.loan_merchants_angel.{{ title }} }}</td>
{% endfor %}
</tr>
{% endfor %}
