Django -如何重定向回搜索页面并包含查询词？

我的页面/视图结构如下：

index.html => search_results.html => object_details.html,
in which user can make a POST request in object_details.html.

我尝试在POST请求后重定向回search_results.html，但同时保留两个查询字符串。
搜索结果的网址如下所示，可以进行一次或两次查询：

www.example.com/search-results/?search_post=xxxxx&search_author=xxxxx

我能得到我想要的最接近的方法是使用：

return redirect(reverse('search-results') + '?' + 'search_post={{search_post}}'+'&'+'search_author={{search_author}}')

然而，这实际上将在search_results.html中的搜索表单的2个字段中的每一个中显示“{{search_post}}”和“{{search_author}}”，并且将返回URL：

**一个

另外，我的search_results视图包含以下内容：

search_post = request.GET.get('search_post')

search_author = request.GET.get('search_author')

我该怎么做？尝试使用类似问题的答案，但尚未弄清楚。谢谢

你只是在引号上犯了一个错误。你不能使用与django模板相同的语法。尝试使用f字符串：

return redirect(reverse('search-results') + f"?search_post={search_post}&search_author={search_author}")

关于字符串的文档：https://peps.python.org/pep-0498/
好的，在你回答之后，我对你的视图做了一个重构。你可以在你的表单处理的每一步重用results来进行下一步的过滤。而且你的，我认为，你的elif链接不好，出错了。

def search_results(request, *args, **kwargs):

    search_post = request.GET.get('search_post', '')
    search_author = request.GET.get('search_author', '')

    results = Post.objects.all()
    if search_author != '':
        results = results.filter(city__icontains=search_author.strip())
    
    if search_post != '':
        results = results.filter(post__icontains=search_post.strip())

    context = {
        'results': results,
        'search_post': search_post,
        'search_author': search_author,
    }

    return render(request, 'search_results.html', context)
