Python 如何搜索数据库并打印结果？

我想做的是让它成为我可以直接搜索数据库的地方，而不必在搜索页面上看到整个数据库。搜索页面应为空。您进行搜索，它会直接进入db条目的详细信息页面，该页面符合您的搜索条件。如果没有匹配项，则显示“未找到匹配项”。我该怎么做

这就是我目前所拥有的。这将在与“我的搜索”框相同的页面上打印/列出数据库中的每个条目，搜索完成后，列表将缩减到与搜索条件匹配的条目数。每个数据库条目都有一个链接，您可以单击该链接，它将带您进入一个详细页面，该页面将调出该条目的信息

我正在使用Django 2.0

Manage.py Views.py 远程列表视图的HTML

{对象_列表%中的对象为%j}
{%if obj.image%}
{%endif%}
{%if obj.user.get_full_name%}
作者：{{obj.user.get_full_name}

{%endif%}
{{obj.orig|truncatechars:120}
{%endfor%}

详细信息视图的HTML

{%if instance.image%}
{%endif%}
{{instance.brand}{{model}}
{%if instance.user.get_full_name%}
作者：{{instance.user.get_full_name}

{%endif%}
最初随提供：{{instance.orig}
{%if instance.comp%}
兼容：{{instance.comp}
{%endif%}

您需要在qs中添加一些代码，但现在一切正常

您需要了解有关筛选查询并将其传递到视图的更多信息。如果您的模型包含标题字段，您可以在模板中{{your_data.title}}使用您的{u data.title}执行筛选后传递的查询

谢谢。我在youtube上浏览了一些教程。最接近我的教程是“CodingTrepreners”的“try django 1.9”，它有38个视频。由于我对这一点是如此陌生，我本应该遵循导师的建议，并遵循django 1.9，但我使用了2.0，这使遵循这一建议成为了一场噩梦。我的网站目前看起来像本教程，并具有相同的功能。
