如何在Django中实现可访问完整数据库的搜索

from django.db import models

class Book(models.Model):
    title = models.CharField(max_length=100)
    author = models.CharField(max_length=100)
    publication_date = models.DateField()

python manage.py makemigrations
python manage.py migrate

from django.shortcuts import render
from .models import Book

def search(request):
    query = request.GET.get('q')
    results = Book.objects.filter(title__icontains=query)
    return render(request, 'search.html', {'results': results, 'query': query})

<form method="GET" action="{% url 'search' %}">
    <input type="text" name="q" placeholder="Search books">
    <button type="submit">Search</button>
</form>

{% if results %}
    <h2>Search results for "{{ query }}"</h2>
    <ul>
        {% for book in results %}
            <li>{{ book.title }} by {{ book.author }}</li>
        {% endfor %}
    </ul>
{% else %}
    <p>No results found for "{{ query }}"</p>
{% endif %}

from django.urls import path
from .views import search

urlpatterns = [
    path('search/', search, name='search'),
    # ...
]
