在Django中提交表单时找不到页面(404) [英] Page not found (404) when submitting a form in Django
问题描述
我正在研究《 Tango With Django》教程.我正在尝试允许用户向该应用程序注册.但是，当用户按下提交"按钮时，出现以下错误消息:
I am working through the Tango With Django tutorial. I am trying to allow the user to register with the app. However, when the user presses the submit button, I get this error message:
Page not found (404)
Request Method: POST
Request URL: http://127.0.0.1:8000/rango/register/rango/register/
Using the URLconf defined in tango_with_django_project.urls, Django tried these URL patterns, in this order:
^admin/
^rango/ ^$ [name='index']
^rango/ ^about$ [name='about']
^rango/ ^add_category/$ [name='add_category']
^rango/ ^category/(?P<category_name_url>\w+)/$ [name='category']
^rango/ ^category/(?P<category_name_url>\w+)/add_page/$ [name='add_page']
^rango/ ^register/$ [name='register']
media/(?P<path>.*)
The current URL, rango/register/rango/register/, didn't match any of these.
我不确定该如何构建怪异的路径.这是注册模板:
I'm not sure how that weird path is being built. Here is registration template:
<!DOCTYPE html>
<html>
<head>
<title>Rango</title>
</head>
<body>
<h1>Register with Rango</h1>
{% if registered %}
Rango says: <strong>thank you for registering!</strong>
<a href="/rango/">Return to the homepage.</a><br />
{% else %}
Rango says: <strong>register here!</strong><br />
<form id="user_form" method="post" action="rango/register/"
enctype="multipart/form-data">
{% csrf_token %}
{{ user_form.as_p }}
{{ profile_form.as_p }}
<input type="submit" name="submit" value="Register" />
</form>
{% endif %}
</body>
</html>
为了进入注册模板，您需要在索引模板中单击以下链接:
In order to get to the registration template, you need to click this link in the index template:
<a href="/rango/register">Register Here</a>
这是rango/views.py中的注册功能:
Here is the register function in rango/views.py:
def register(request):
registered = False
if request.method == 'POST':
user_form = UserForm(data=request.POST)
profile_form = UserProfileForm(data=request.POST)
if user_form.is_valid() and profile_form.is_valid():
user = user_form.save()
user.set_password(user.password)
user.save()
profile = profile_form.save(commit=False)
profile.user = user
if 'picture' in request.FILES:
profile.picture = request.FILES['picture']
profile.save()
registered = True
else:
print user_form.errors, profile_form.errors
else:
user_form = UserForm()
profile_form = UserProfileForm()
return render(request,
'rango/register.html',
{'user_form': user_form, 'profile_form': profile_form, 'registered': registered})
我确定我缺少一些小东西！
I am sure I am missing something small!
推荐答案
当前，您的浏览器将"rango/register/" 添加到当前URL的末尾.如果将其更改为"./" 或"/rango/register/" ，它会指向自身，但这并不是最佳实践.
Currently you browser adds "rango/register/" to the end of the current URL.
If you changed it to "./" or "/rango/register/" it would point to itself, however these are not best practise.
为获得最佳实践，请使用 {％url"register"％} ，那样，当您更改url.py时，它将自动更改.
For best practise use {% url "register" %} instead, that way it will automatically change is you change your url.py
例如:
<form id="user_form" method="post" action="{% url "register" %}"
enctype="multipart/form-data">
