Django2:在表单提交后，有没有更好的方法来“擦除”帖子以阻止重新提交

from django.shortcuts import render, redirect
from .forms import PostForm

def create_post(request):
    if request.method == 'POST':
        form = PostForm(request.POST)
        if form.is_valid():
            # 处理有效的表单数据
            post = form.save()
            return redirect('post_detail', pk=post.pk)
    else:
        form = PostForm()
    return render(request, 'create_post.html', {'form': form})
