如何让用户能够过滤模型中的某个字段(Django)

from django.db import models

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

from django.shortcuts import render
from .models import Book

def filter_books(request):
    genre = request.GET.get('genre')  # 获取用户传递的过滤条件

    # 使用filter()方法过滤模型中的字段
    filtered_books = Book.objects.filter(genre=genre)

    return render(request, 'books.html', {'books': filtered_books})

{% for book in books %}
    <p>Title: {{ book.title }}</p>
    <p>Author: {{ book.author }}</p>
    <p>Genre: {{ book.genre }}</p>
{% endfor %}

from django.urls import path
from .views import filter_books

urlpatterns = [
    path('filter/', filter_books, name='filter_books'),
]
