在 Django 中编辑搜索视图

你好，我正在 django 工作，如何使用 Django 文档站点的搜索表单。以下是一些信息。现在，有没有办法可以生成标题的部分搜索？例如，如果我想搜索一本名为“Apress”的书，但我没有输入整个单词，而是输入“ap”来获取 Apress。有没有办法实现这个解决方案？

    from django.db.models import Q
    from django.shortcuts import render_to_response
    from models import Book

    #views.py
    def search(request):
        query = request.GET.get('q', '')
        if query:
            qset = (
                Q(title__icontains=query) |
                Q(authors__first_name__icontains=query) |
                Q(authors__last_name__icontains=query)
            )
            results = Book.objects.filter(qset).distinct()
        else:
            results = []
        return render_to_response("books/search.html", {
            "results": results,
            "query": query
        })

    #search html

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN">
    <html lang="en">
    <head>
        <title>Search{% if query %} Results{% endif %}</title>
    </head>
    <body>
      <h1>Search</h1>
      <form action="." method="GET">
        <label for="q">Search: </label>
        <input type="text" name="q" value="{{ query|escape }}">
        <input type="submit" value="Search">
      </form>

      {% if query %}
        <h2>Results for "{{ query|escape }}":</h2>

        {% if results %}
          <ul>
          {% for book in results %}
            <li>{{ book|escape }}</l1>
          {% endfor %}
          </ul>
        {% else %}
          <p>No books found</p>
        {% endif %}
      {% endif %}
    </body>
    </html>

Hello I am working in django how to use a search form from Django documents site. Here are some information below.
Now, is there a way I can produce a part search for title? For example if I wanted to search for a book called "Apress", But instead of typing the whole word I just wrote "ap" to get Apress. Is there a way how to achieve this solution?

    from django.db.models import Q
    from django.shortcuts import render_to_response
    from models import Book

    #views.py
    def search(request):
        query = request.GET.get('q', '')
        if query:
            qset = (
                Q(title__icontains=query) |
                Q(authors__first_name__icontains=query) |
                Q(authors__last_name__icontains=query)
            )
            results = Book.objects.filter(qset).distinct()
        else:
            results = []
        return render_to_response("books/search.html", {
            "results": results,
            "query": query
        })

    #search html

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN">
    <html lang="en">
    <head>
        <title>Search{% if query %} Results{% endif %}</title>
    </head>
    <body>
      <h1>Search</h1>
      <form action="." method="GET">
        <label for="q">Search: </label>
        <input type="text" name="q" value="{{ query|escape }}">
        <input type="submit" value="Search">
      </form>

      {% if query %}
        <h2>Results for "{{ query|escape }}":</h2>

        {% if results %}
          <ul>
          {% for book in results %}
            <li>{{ book|escape }}</l1>
          {% endfor %}
          </ul>
        {% else %}
          <p>No books found</p>
        {% endif %}
      {% endif %}
    </body>
    </html>

如果您想在字段的开头进行匹配，则可以使用 startswith 或 istartswith （如果您希望区分大小写）。您现在使用的 icontains 即使在字符串内也允许匹配，即。 “arry”将匹配“Harry”。虽然 startswith 将允许 'Har' 匹配 'Harry'，但不允许 'ArHarHar'
