如何在django中获取所选单选按钮的pk

# views.py

from django.shortcuts import render

def my_view(request):
    if request.method == 'POST':
        selected_option = int(request.POST.get('my_radio_button'))
        # 根据pk值查询数据库获取对象
        # ...
        return render(request, 'result.html', {'selected_option': selected_option})
    else:
        return render(request, 'form.html')

<!-- form.html -->

<form method="post" action="{% url 'my_view' %}">
  {% csrf_token %}
  <input type="radio" name="my_radio_button" value="1">
  <label>选项1</label><br>
  <input type="radio" name="my_radio_button" value="2">
  <label>选项2</label><br>
  <input type="submit" value="提交">
</form>

<!-- result.html -->

<p>您选择了选项 {{ selected_option }}</p>
