Question

我正在尝试制作允许用户更改密码的表单和方法。当用户将其密码键入两个输入而不是表单时，将检查它们是否相同并更新db。但是我得到了这个错误，我无法解决它。

错误消息

<html>

    <body onload="brython()">

            from browser import document, alert

            def echo(ev):
                alert(document["zone"].value)

            document['mybutton'].bind('click', echo)

urls.py

NoReverseMatch at /blog/password_change/blue/
Reverse for 'profile' with arguments '()' and keyword arguments '{}' not found. 1 pattern(s) tried: [u'blog/profile/(?P<username>[-\\w.]+)/$']

views.py

url(r'^password_change/(?P<username>[-\w.]+)/$', views.password_change, name='password_change'),
url(r'^profile/(?P<username>[-\w.]+)/$', views.profile, name='profile'),

profile.html。这是模板。

def password_change(request, username):
if request.method == 'POST':
    form = PasswordChangeForm(data=request.POST, user=request.user)

    if form.is_valid():
        form.save()
        update_session_auth_hash(request, form.user)
        return redirect(reverse('blog:profile'))
    else:
        return redirect(reverse('blog:profile'))
else:
    form = PasswordChangeForm(user=request.user)

    return HttpResponseRedirect('/blog/')

views.py

 <form class="form-horizontal" role="form" action="{% url'blog:password_change' user.username %}" method="post" enctype="multipart/form-data">
{% csrf_token %}
<label for="password1">new password</label>
 <div class="row">
    <input type="password" name="password1" id="password1"/></div>
<div class="row">
<label for="password2">password check</label></div>
 <div class="row">
    <input type="password" name="password2" id="password2"/></div>
 <div class="row">  
      <button type="submit" class="button-primary">change password</button></div>

这是forms.py

def password_change(request, username):
if request.method == 'POST':
    form = PasswordChangeForm(data=request.POST, user=request.user)

    if form.is_valid():
        form.save()
        update_session_auth_hash(request, form.user)
        return redirect(reverse('blog:profile'))
    else:
        return redirect(reverse('blog:profile'))
else:
    form = PasswordChangeForm(user=request.user)

    return HttpResponseRedirect('/blog/')

Answer 1

正如您的错误所述，您需要在个人资料网址中提供您的用户名参数，而您根本不提供该参数。

例如：

 return redirect(reverse('blog:profile'))

应该是

 return redirect(reverse('blog:profile', args=[form.user.get_username()]))

Answer 2

您必须将用户名传递给reverse（）。

username = form.user.get_username（）

reverse（'blog：profile'，kwargs = {'username'：username}）
