Question

我有一个视图接受来自用户的输入，并且在成功的帖子上，它会重定向到另一个页面。它与教程中的代码完全相同：

def quex(request, id, question_number):

    next_question = int(question_number) + 1
    if request.method == 'POST': # If the form has been submitted...
        form = ContactForm(request.POST) # A form bound to the POST data
        if form.is_valid(): # All validation rules pass
            # Process the data in form.cleaned_data
            # ...
            return HttpResponseRedirect('/quex/' + id + '/' + str(next_question)) 
    else:
        form = QuestionForm() # An unbound form

    return render_to_response('questionnaire.html', {
        'form': form,
        'id' : id,
        'question_number' : question_number},
        RequestContext(request)

urls.py

urlpatterns = patterns('',    
    url(r'^$', 'django.contrib.auth.views.login'),
    url(r'^logout$', 'screening.views.logout_view'),
    url(r'^home/$', 'screening.views.home'),
    url(r'^quex/new/$', 'screening.views.new_quex'),
    # others omitted
    url(r'^quex/(?P<identifier>\w{8})/(?P<question_number>\d+)/', 'screening.views.quex'),
)

代码似乎有效，页面行为正常。

我的问题是客户端中显示的网址无法正确更新。原始页面为http://foo.com/questionnaire/ / 1 /，重定向页面为http://foo.com/questionnaire/ / 2 /。即使在重定向之后，旧URL仍继续显示在浏览器的地址栏中。

服务器状态消息看起来很好：

[19/Aug/2013 19:15:40] "GET /quex/P54C9UCS/1/ HTTP/1.1" 200 3225
[19/Aug/2013 19:15:44] "POST /quex/P54C9UCS/1/ HTTP/1.1" 302 0
[19/Aug/2013 19:15:44] "GET /quex/P54C9UCS/2/ HTTP/1.1" 200 3206

我做错了什么？如何让浏览器显示正确的URL？

编辑：我做了一些测试。 Chrome，Safari（在OS X和iOS上）和Firefox如上所述显示URL。但iOS上的Browser Khmer会将网址显示为http://foo.com/quex/<id>/1/#/quex/<id>/2/。

没有测试，但是：

<强> urls.py

urlpatterns = patterns('',    
    url(r'^$', 'django.contrib.auth.views.login'),
    url(r'^logout$', 'screening.views.logout_view'),
    url(r'^home/$', 'screening.views.home'),
    url(r'^quex/new/$', 'screening.views.new_quex'),
    # others omitted
    url(r'^quex/(?P<identifier>\w{8})/(?P<question_number>\d+)/$', 'screening.views.quex', name='quex-view'),
)

<强> views.py

from django.core.urlresolvers import reverse_lazy


def quex(request, identifier, question_number):

    next_question = int(question_number) + 1
    if request.method == 'POST': # If the form has been submitted...
        form = ContactForm(request.POST) # A form bound to the POST data
        if form.is_valid(): # All validation rules pass

            response_url = reverse_lazy('quex-view', kwargs={'identifier':identifier, 'question_number':next_question})
            return HttpResponseRedirect(reponse_url) 
    else:
        form = QuestionForm() # An unbound form

    return render_to_response('questionnaire.html', {
        'form': form,
        'identifier' : identifier,
        'question_number' : question_number},
        RequestContext(request)

Answer 2

你的最后一个quex正则表达式以/结尾，而不是/ $。先改变一下。你说你已经在视图中切换到反转，这样单个正则表达式更改就可以了。

Answer 3

由于您正在将views方法作为递归调用，因此出现此错误。这里返回HttpResponseRedirect（'/ quex /'+ id +'/'+ str（next_question））再次调用同样的方法，唯一的区别是request.method将从POST更改为GET。第二次作为get方法，这将调用return render_to_response，你会看到页面。我希望你能完成我的工作。

更改您的代码：

def quex(request, id, question_number):
    next_question = int(question_number) + 1
    if request.method == 'POST': # If the form has been submitted...
        form = ContactForm(request.POST) # A form bound to the POST data
        if form.is_valid(): # All validation rules pass
            # Process the data in form.cleaned_data
            # ...
            # Next line I have written, so you will get same value of question_number as you get after returning from HttpResponseRedirect
            question_number =  next_question + 1 
    form = QuestionForm() # An unbound form

    return render_to_response('questionnaire.html', {
        'form': form,
        'id' : id,
        'question_number' : question_number},
        RequestContext(request)

此代码将作为您当前的代码。没有任何错误。希望这对你有所帮助。

Answer 4

浏览器在网址栏中显示的内容取决于您的客户端代码：

简单的HTML表单将正确重定向。
jquery的$.ajax()来电not redirect by default，所以即使代码有效，客户也不会重定向。

Answer 5

def quex(request, identifier, question_number):

    next_question = int(question_number) + 1
    if request.method == 'POST':
        form = ContactForm(request.POST)
        if form.is_valid():
            return HttpResponseRedirect('/quex/' + identifier + '/' + str(next_question)) 
    else:
        form = QuestionForm() # An unbound form

    return render_to_response('questionnaire.html', {
        'form': form,
        'id' : identifier,
        'question_number' : question_number})

您的render_to_response()缺少尾随)
render_to_response()的第三个参数是可选的。我通常会把它关掉。但是，根据文档，我会将其作为命名参数传递。 enter link description here
终于：您的def quex(request, id, question_number):应为def quex(request, identifier, question_number):，以便与网址格式相匹配。同时将quex主体中的id引用更改为标识符（我在示例代码中包含）

使用HttpResponseRedirect，但浏览器未显示正确的URL
