如何使用模型对象作为django-filter MultipleChoiceFilter的选择

pip install django-filter

from django.db import models

class Category(models.Model):
    name = models.CharField(max_length=100)

import django_filters
from .models import Category

class CategoryFilter(django_filters.FilterSet):
    category = django_filters.ModelChoiceFilter(queryset=Category.objects.all())

    class Meta:
        model = Category
        fields = ['category']

from django.shortcuts import render
from .models import Product
from .filters import CategoryFilter

def product_list(request):
    queryset = Product.objects.all()
    filter = CategoryFilter(request.GET, queryset=queryset)
    filtered_queryset = filter.qs

    return render(request, 'product_list.html', {'filter': filter, 'products': filtered_queryset})

<form method="get">
    {{ filter.form.as_p }}
    <button type="submit">Filter</button>
</form>

{% for product in products %}
    <p>{{ product.name }}</p>
{% empty %}
    <p>No products found.</p>
{% endfor %}
