问题描述
当前在Django中工作，并尝试在表单上做一个简单的教程，但是提交表单时出现错误.
currently working in Django and trying to do a simple tutorial on forms, but I am receiving an error when the form is submitted.
这是我的urls.py:
Here is my urls.py:
from .views import*
urlpatterns = [
url(r'^name/', get_name, name='TheName'),
url(r'^name/present/', present, name='Present'),
]
以下是视图:
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:
Here is name.html:
<form action="present/" method="post">
{% csrf_token %}
{{ form }}
<input type="submit" value="Submit" />
</form>
这是我的present.html:
Here is my present.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>{{ your_name }}</title>
</head>
<body>
</body>
</html>
单击提交后，并显示带有追溯的错误消息:
After submit is clicked, and error message with the traceback:

任何帮助将不胜感激！
推荐答案
成功提交表单后，您需要告诉重定向到何处.您只在执行 return HttpResponseRedirect 这是无效的，而应该是:
You need to tell where to redirect after successful form submission. You are only doing return HttpResponseRedirect which is not valid, instead it should be:
return HttpResponseRedirect(the_path_to_redirect_to)
请阅读有关 HttpResponseRedirect 的文档
