如何在django的db中保存选定的单选按钮

from django.db import models

class MyModel(models.Model):
    RADIO_CHOICES = (
        ('option1', 'Option 1'),
        ('option2', 'Option 2'),
        ('option3', 'Option 3'),
    )
    radio_field = models.CharField(max_length=10, choices=RADIO_CHOICES)

from django.shortcuts import render
from .models import MyModel

def my_view(request):
    if request.method == 'POST':
        selected_option = request.POST.get('radio_field')
        my_model = MyModel(radio_field=selected_option)
        my_model.save()
        # 其他处理逻辑
    else:
        # 渲染包含单选按钮的表单页面
        return render(request, 'my_template.html')

<form method="post" action="{% url 'my_view' %}">
  {% csrf_token %}
  <input type="radio" name="radio_field" value="option1"> Option 1<br>
  <input type="radio" name="radio_field" value="option2"> Option 2<br>
  <input type="radio" name="radio_field" value="option3"> Option 3<br>
  <input type="submit" value="Submit">
</form>
