我当前的表单提交正确，但是在每次提交表单后在django管理员中添加其他列表。我上了一堂 SELECT attach_id,post_msg_id
FROM
(SELECT Distinct phpbb_attachments.attach_id,
FROM phpbb_attachments
INNER JOIN phpbb_topics
ON phpbb_attachments.topic_id = phpbb_topics.topic_id
INNER JOIN phpbb_forums ON phpbb_topics.forum_id = phpbb_forums.forum_id
WHERE phpbb_attachments.is_orphan = 0
AND phpbb_attachments.thumbnail = 1
AND (phpbb_attachments.extension = 'jpg'
OR phpbb_attachments.extension = 'png'
OR phpbb_attachments.extension = 'gif')
AND phpbb_forums.forum_id BETWEEN 668 AND 679
ORDER BY phpbb_attachments.attach_id DESC
LIMIT 50) as firstDistinct
LEFT JOIN
(SELECT phpbb_attachments.attach_id, phpbb_attachments.post_msg_id
FROM phpbb_attachments
INNER JOIN phpbb_topics
ON phpbb_attachments.topic_id = phpbb_topics.topic_id
INNER JOIN phpbb_forums ON phpbb_topics.forum_id = phpbb_forums.forum_id
WHERE phpbb_attachments.is_orphan = 0
AND phpbb_attachments.thumbnail = 1
AND (phpbb_attachments.extension = 'jpg'
OR phpbb_attachments.extension = 'png'
OR phpbb_attachments.extension = 'gif')
AND phpbb_forums.forum_id BETWEEN 668 AND 679
ORDER BY phpbb_attachments.attach_id DESC
LIMIT 50) as secondNotDistinct
On firstDistinct.attach_id = secondNotDistinct.attach_id
类，以为这可以解决问题，而且没有运气。
由于我是Django的新手，所以我想念一些东西。
我只需要使用此表单即可根据当前用户更新django管理员中的值，而无需重复创建其他列表。
用当前代码执行此操作的最佳方法是什么？
我很感激任何帮助，干杯
