如何在模型表单中使用自动完成选择小部件

# models.py
from django.db import models

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

class Product(models.Model):
    name = models.CharField(max_length=100)
    category = models.ForeignKey(Category, on_delete=models.CASCADE)

# forms.py
from django import forms
from .models import Product

class ProductForm(forms.ModelForm):
    class Meta:
        model = Product
        fields = ['name', 'category']
        widgets = {
            'category': forms.TextInput(attrs={'data-autocomplete-url': '/autocomplete/category'}),
        }

# views.py
from django.http import JsonResponse
from django.views.decorators.http import require_GET
from .models import Category

@require_GET
def autocomplete_category(request):
    term = request.GET.get('term', '')
    categories = Category.objects.filter(name__icontains=term)
    results = [category.name for category in categories]
    return JsonResponse(results, safe=False)

# template.html
<form method="post" action="{% url 'product_create' %}">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">Submit</button>
</form>

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script>
  $(document).ready(function() {
    $('[data-autocomplete-url]').each(function() {
      $(this).autocomplete({
        source: $(this).data('autocomplete-url')
      });
    });
  });
</script>
