Question

在我的Bartertown函数中由于某种原因它完全跳过if循环。我打印出每个变量，以便在日志中显示第一个变量"Paste"应该使用domain/Thunderdome/Bartertown在thunderdome/paste_form呈现新页面，当它实际忽略循环并直接进入{ {1}}

thunderdome /浏览次数

return HttpResponse

^^^跳过class SquirrelView(View): def post (self, request): form = request.POST.get("thundersubmit", "") if form == '1': request.session["_thundersubmit"] = 'Pool' return HttpResponseRedirect('Bartertown') if form == '2': request.session["_thundersubmit"] = 'Paste' return HttpResponseRedirect('Bartertown') if form == '3': request.session["_thundersubmit"] = 'Upload' return HttpResponseRedirect('Bartertown') return HttpResponseRedirect('home') def Bartertown(request): statusly = request.session.get('_thundersubmit') print statusly if statusly == 'Paste': render(request, 'thunderdome/paste_form.html') return HttpResponse(statusly)语句，如错误日志中所示，If应该有＆＃34;命中＆＃34;该循环和渲染的paste_form.html，当真正发生的事情是它跳过循环并直接转到'Paste'。

网址

return HttpResponse(statusly)

thunderdome / test_forms.html

    url(r'^Thunderdome/squirrel', SquirrelView.as_view()),

为什么会这样？我遗漏了基于函数的视图与基于类的视图的内容吗？

您实际上并未在if块内返回HttpResponse语句生成的render。尝试更改：

if statusly == 'Paste':
    render(request, 'thunderdome/paste_form.html')

为：

if statusly == 'Paste':
    return render(request, 'thunderdome/paste_form.html')

正如您在the documentation中看到的那样，render方法返回HttpResponse个对象。您正在放弃该响应并进入return HttpResponse(statusly)声明。

Django功能视图跳过循环？
