Django如何在选择输入中显示选择

GENDER_CHOICES = (
    ('M', 'Male'),
    ('F', 'Female'),
    ('O', 'Other'),
)

from django import forms

class GenderForm(forms.Form):
    gender = forms.ChoiceField(choices=GENDER_CHOICES)

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

from django.shortcuts import render

def gender_view(request):
    if request.method == 'POST':
        form = GenderForm(request.POST)
        if form.is_valid():
            selected_gender = form.cleaned_data['gender']
            # 处理选择的性别
            return render(request, 'success.html', {'gender': selected_gender})
    else:
        form = GenderForm()
    return render(request, 'gender.html', {'form': form})
