我被这个问题缠住了,不知道出了什么问题
我尝试过的
感谢您的帮助。提前谢谢你 在您的
博客/edit_post.html
中使用post.id
<form action="{% url 'edit_post' post.id %}" method='post'>
...
</form>
def edit_post(request, post_id):
post = BlogPost.objects.get(id=post_id)

if request.method != 'POST':
form = BlogForm(instance=post)
else:
form = BlogForm(instance=post, data=request.POST)
if form.is_valid():
form.save()
return HttpResponseRedirect(reverse('index'))
context = {'title': title, 'text': text, 'form': form}
return render(request, 'blog/edit_post.html', context)
