Question

问题似乎出在“ if request.method =='POST'：”这一行。任何帮助表示赞赏。

Answer 1

1. if instance.user == request.user:
2.    form = TestimonyForm(request.POST or None, request.FILES or None, instance=instance)
3.     print('a')
4.     return render(request, 'variablized_form.html', {"form": form})
5.     if request.method=='POST':
6.         form = TestimonyForm(request.POST or None, request.FILES or None, instance=instance)

查看此代码块。在第1行中，它检查instance.user == request.user是否为 True ，然后转到第2行 然后在控制台/终端机中的第3行中打印其a。然后转到第4行并返回模板。因此，无论如何都无法转到第5行。

因此，如果要到达第5行，则需要删除第4行，然后找到任何错误来解决此问题。

更新：

print('a')
# here you remove previous line
if request.method=='POST':
        form = TestimonyForm(request.POST or None, request.FILES or None, instance=instance)
        if form.is_valid():
            print('3')
            instance=form.save(commit=False)
            instance.save()
            print('2')
            context={
                "testimony":testimony
            }

            return render(request, 'testimony_post.html', context)
return render(request, 'variablized_form.html', {"form": form})

Editpost功能不起作用。 “ if request.method =='POST'：”问题
