我在django中使用复选框值列表来过滤数据

from django.db import models

class Book(models.Model):
    GENRE_CHOICES = (
        ('F', 'Fiction'),
        ('N', 'Non-fiction'),
        ('M', 'Mystery'),
        # 其他类型...
    )
    title = models.CharField(max_length=100)
    genre = models.CharField(max_length=1, choices=GENRE_CHOICES)
    # 其他字段...

from django import forms

class BookFilterForm(forms.Form):
    GENRE_CHOICES = (
        ('F', 'Fiction'),
        ('N', 'Non-fiction'),
        ('M', 'Mystery'),
        # 其他类型...
    )
    genre = forms.MultipleChoiceField(choices=GENRE_CHOICES, widget=forms.CheckboxSelectMultiple)

from django.views.generic import ListView
from .models import Book

class BookListView(ListView):
    model = Book
    template_name = 'book_list.html'
    context_object_name = 'books'

    def get_queryset(self):
        queryset = super().get_queryset()
        form = BookFilterForm(self.request.GET)
        if form.is_valid():
            genres = form.cleaned_data['genre']
            queryset = queryset.filter(genre__in=genres)
        return queryset

{% for book in books %}
    <h3>{{ book.title }}</h3>
    <p>Genre: {{ book.get_genre_display }}</p>
    <!-- 其他字段... -->
{% empty %}
    <p>No books found.</p>
{% endfor %}
