在Django使用窗体 - 获得（）失踪1个人需要的位置参数：“头”

问题描述：

目前在Django工作，努力做一个形式简单的教程，但表单提交时我收到一个错误。在Django使用窗体 - 获得（）失踪1个人需要的位置参数：“头”

这里是我的urls.py：

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

这里有意见：

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')

这里是形式：

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>

这里是我的present.html：

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

</body> 
</html>

后提交被点击，和错误消息回溯：

Environment: 

Request Method: POST

任何帮助，将不胜感激！

答

你需要告诉那里成功的表单提交后重定向。你只是做return HttpResponseRedirect这是无效的，相反，它应该是：

return HttpResponseRedirect(the_path_to_redirect_to)

请阅读文档中关于HttpResponseRedirect。

我现在意识到我的错误！谢谢你！ – SkillaPop
