目前在 Django 中工作并尝试做一个关于表单的简单教程，但是在提交表单时收到错误消息。

这是我的 urls.py：

from .views import*
urlpatterns = [
url(r'^name/', get_name, name='TheName'),
url(r'^name/present/', present, name='Present'),
]

以下是观点：

def get_name(request):
   if request.method == 'POST':
    form = NameForm(request.POST)
    if form.is_valid():
        return HttpResponseRedirect
   else:
    form = NameForm()

   return render(request, 'home/name.html', {'form': form})


def present(request):
   return render(request, 'home/present.html')

这是表格：

class NameForm(forms.Form):
    your_name = forms.CharField(label='Your name', max_length=100)

这里是name.html：

<form action="present/" method="post">
   {% csrf_token %}
   {{ form }}
   <input type="submit" value="Submit" />
</form>

这是我的present.html：

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>{{ your_name }}</title>
</head>
<body>

</body>
</html>

点击提交后，回溯错误信息：

Environment:

Request Method: POST
Request URL: http://localhost:8000/name/present/

任何帮助将不胜感激！

【解决方案1】：

您需要告诉表单提交成功后重定向到哪里。你只是在做return HttpResponseRedirect 这是无效的，应该是：

return HttpResponseRedirect(the_path_to_redirect_to)

请阅读有关 HttpResponseRedirect 的文档。
