我无法从HTML表单中获取数据并将其保存到django中的数据库中

# forms.py
from django import forms

class MyForm(forms.Form):
    name = forms.CharField(max_length=100)
    email = forms.EmailField()
    message = forms.CharField(widget=forms.Textarea)

# views.py
from django.shortcuts import render
from .forms import MyForm
from .models import MyModel

def my_view(request):
    if request.method == 'POST':
        form = MyForm(request.POST)
        if form.is_valid():
            name = form.cleaned_data['name']
            email = form.cleaned_data['email']
            message = form.cleaned_data['message']
            
            # 保存数据到数据库
            MyModel.objects.create(name=name, email=email, message=message)
            
            # 可以根据需要进行其他操作，如重定向到成功页面等
            return render(request, 'success.html')
    else:
        form = MyForm()
    
    return render(request, 'my_form.html', {'form': form})
