Django:我如何创建一个动态表单，可以在用户点击时改变？

from django import forms

class MyForm(forms.Form):
    name = forms.CharField(max_length=100)
    email = forms.EmailField()
    country = forms.ChoiceField(choices=[('US', 'United States'), ('CA', 'Canada')])

from django.shortcuts import render

def my_view(request):
    if request.method == 'POST':
        form = MyForm(request.POST)
        if form.is_valid():
            # 处理有效的表单数据
            name = form.cleaned_data['name']
            email = form.cleaned_data['email']
            country = form.cleaned_data['country']
            # 其他处理逻辑
    else:
        form = MyForm()
    
    return render(request, 'my_template.html', {'form': form})

<form method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="提交">
</form>
