python - 如何在django中实现基本搜索？

Question

搜索框获取数据但不显示任何结果。这是我到目前为止的代码:

views.py

def search(request):
if 'q' in request.GET and request.GET['q']:
    q = request.GET['q']
    books = Advent.objects.filter(title__icontains=q)
    return render(request, 'search_results.html', {'books': books, 'query': q})
else:
    return HttpResponse('Please submit a search term.')

urls.py

    url(r'^your_url/?$', 'myblog.views.search', name='your_url_name'),

search_results.html

<p>You searched for: <strong>{{ query }}</strong></p>

{% if books %}
<p>Found {{ books|length }} book{{ books|pluralize }}.</p>
<ul>
    {% for book in books %}
    <li>{{ book.title }}</li>
    {% endfor %}
</ul>
{% else %}
<p>No books matched your search criteria.</p>
{% endif %}

index.html

<form type="get" action=".">
<input type="search" id="q" name="q" placeholder="Search..."/>
</form>

如果我正确理解您的问题，请在不正确的地址上发送请求，更改操作属性:

<form type="get" action="{% url 'your_url_name' %}">

然后表单会将请求发送到正确的地址，而不是在index.html上
