Python django如何在name_znat字段中使用下拉元素输入用户选择的文本

from django.db import models

class YourModel(models.Model):
    name_znat = models.CharField(max_length=100)

from django import forms

class YourForm(forms.Form):
    CHOICES = (
        ('option1', 'Option 1'),
        ('option2', 'Option 2'),
        ('option3', 'Option 3'),
    )
    name_znat = forms.ChoiceField(choices=CHOICES)

from django.shortcuts import render
from .forms import YourForm

def your_view(request):
    form = YourForm()
    return render(request, 'your_template.html', {'form': form})

<form method="post">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">Submit</button>
</form>

def your_view(request):
    if request.method == 'POST':
        form = YourForm(request.POST)
        if form.is_valid():
            name_znat = form.cleaned_data['name_znat']
            # 保存到数据库或进行其他操作
    else:
        form = YourForm()
    return render(request, 'your_template.html', {'form': form})
