    class Meta:
        model = YourModel
        fields = ['related_field', 'other_field1', 'other_field2']

from .forms import YourModelForm

def your_view(request):
    if request.method == 'POST':
        form = YourModelForm(request.POST)
        if form.is_valid():
            form.save()
            # 处理表单提交成功的逻辑
    else:
        form = YourModelForm()
    
    return render(request, 'your_template.html', {'form': form})
