Question

尝试从数据库检索数据并在网页上显示时出现模板语法错误。不明白为什么，因为所有Jinja语法检查出来。

这是html / jinja

def check(i, templates_dict=None, **kwargs):
    return len(templates_dict["data_list"].split(",")) > i

dag = DAG(
    dag_name,
    default_args=default_args,
    schedule_interval=None
)

load = CustomOperator(
    task_id="load_op",
    bash_command=' '.join([
        './command.sh'
        '--data-list {{ dag_run.conf["data_list"]|join(",") }}'
    ]),
    dag=dag
)

for i in range(0, 5):
    condition = SkipOperator(
        task_id=f"{dag_name}_condition_{i}",
        python_callable=partial(check, i),
        provide_context=True,
        templates_dict={"data_list": '{{ dag_run.conf["data_list"]|join(",") }}'},
        dag=dag
    )
    gs_filename = 'prefix_{{ dag_run.conf["data_list"][%d] }}.json' % i

    load_to_gcs = CustomFileToGoogleCloudStorageOperator(
        task_id=f"{dag_name}_to_gs_{i}",
        src='/tmp/{{ run_id }}_%d.{{ dag_run.conf["file_extension"] }}' % i,
        bucket=gs_bucket,
        dst=gs_filename,
        mime_type='application/json',
        google_cloud_storage_conn_id=connection_id,
        dag=dag
    )
    load_to_bq = GoogleCloudStorageToBigQueryOperator(
        task_id=f"{dag_name}_to_bq_{i}",
        bucket=gs_bucket,
        source_objects=[gs_filename, ],
        source_format='NEWLINE_DELIMITED_JSON',
        destination_project_dataset_table='myproject.temp_{{ dag_run.conf["data_list"][%d] }}' % i,
        bigquery_conn_id=connection_id,
        schema_fields={},
        google_cloud_storage_conn_id=connection_id,
        write_disposition='WRITE_TRUNCATE',
        dag=dag
    )

    condition.set_upstream(load)
    load_to_gcs.set_upstream(condition)
    load_to_bq.set_upstream(load_to_gcs)

以下是错误说法：

<table>
{% for row in search %}
        <tr>
        <th> ID </th>
                <td> {{row['hostname'] }}</td>
        <th> hostName </th>
                <td> {{ row['ID'] }}</td>
        <th> reportName </th>
                <td>{{ row['reportName'] }} </td>
        </tr>
{% endfor %}
</table>
</body>
</html>

这是我查询数据库以检索这些项目的地方：

 File "/home/ttataryn/FlaskApp/templates/result.html", line 631, in template
    {% endfor %}
TemplateSyntaxError: Unexpected end of template. Jinja was looking for the following tags: 'endfor' or 'else'. The innermost block that needs to be closed is 'for'.

Jinja 2模板语法错误 - jinja2.exceptions.TemplateSyntaxError
