如何在Django中编辑表单时将其保存到数据库中？

# models.py
from django.db import models

class MyForm(models.Model):
    name = models.CharField(max_length=100)
    email = models.EmailField()
    message = models.TextField()

# forms.py
from django import forms
from .models import MyForm

class MyFormForm(forms.ModelForm):
    class Meta:
        model = MyForm
        fields = ['name', 'email', 'message']

# views.py
from django.shortcuts import render, redirect
from .forms import MyFormForm

def edit_form(request):
    if request.method == 'POST':
        form = MyFormForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect('success')  # 重定向到成功页面
    else:
        form = MyFormForm()
    return render(request, 'edit_form.html', {'form': form})

# edit_form.html
<form method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">保存</button>
</form>
