django - 在我的 View 中使用多个提交按钮时，属性错误 'WSGIRequest' 对象没有属性 'Post'

Question

我正在制作一个博客应用程序，我需要在提交他的博客时为用户提供多个按钮。我正在检查设置了哪个按钮并尝试相应地执行操作，但它无法正常工作。

这是我的 View 部分，我正在检查 POST 数据中设置了哪个按钮，但是当我单击发布时它工作正常，但是如果我单击保存或发布，则会出现错误
属性错误 'WSGIRequest' 对象没有属性 'Post'

@login_required
def blog_form(request,author_id=None,slug=None):

    context_instance=RequestContext(request)

    # This view will have a valid creator_id and slug field if the
    # blog is being edited and in this case the creator and user should be same
    if ( author_id and slug):
        author = User.objects.get(pk=author_id)
        blog = get_object_or_404(Entry, creator = author, slug = slug)
        if blog.creator != request.user:
            raise HttpResponseForbidden()

    # We set the user and created date and make a new object
    else:
        blog = Entry(creator=request.user,created_date=datetime.datetime.now() )

    if request.method == 'POST':

        #if the blog is not published
        if 'save' in request.POST:
            form = EntryForm(request.Post, instance = blog)
            if form.is_valid():
                form.save()

        elif 'publish' in request.POST:
            blog.pub_date = datetime.datetime.now()
            blog.status = 1
            form = EntryForm(request.POST, instance = blog)
            if form.is_valid():
                form.save()
                return render_to_response('blog/blog_view.html', {'blog': blog,},context_instance=RequestContext(request))

        elif 'preview' in request.POST: 
            form = EntryForm(request.Post, instance = blog)
            if form.is_valid():
                form.save()
                return render_to_response('blog/blog_view.html', {'blog': blog,},context_instance=RequestContext(request))

    else:
        form = EntryForm(instance = blog)

    return render_to_response('blog/blog.html', {'form':form}, context_instance)

异常(exception)是告诉您您需要知道的一切 - 请求时没有“发布”属性。但是，有 request.POST
