Python Django——在一种观点中，我该如何做；返回render/Httpresponse/etc“；换个角度看？

比如说我有一个叫做addPost的视图（就像一个墙柱）。这是一个post对象的模型表单页面。有两种情况，request.method是post，或者不是。如果是POST方法，我希望在提交POST后返回到profile页面

我有过几次这样的问题，它通常以NoReverseMatch错误的形式出现

如何将render/Httpresponse/etc“返回”到另一个视图？在Django？我觉得我以前使用过的任何解决方案都是非常粗糙的，我想知道实现这种特性的正确方法

我想指出的是，我在myapp/profile.html上遇到了这个错误

{% if user == currUser %}

                  <a href="
      {% url 'addpost' %}
      " class = "btn btn-info"> <span class="glyphicon glyphicon-plus"></span></a>


 {% endif %}

这是我的追踪记录：

它出现在html中的这一行代码中，该按钮链接到add_post视图

profile.html

{% if user == currUser %}

                  <a href="
      {% url 'addpost' %}
      " class = "btn btn-info"> <span class="glyphicon glyphicon-plus"></span></a>


 {% endif %}

这是两个视图，profile和add_post

@login_required
def profile(request, id):
    context = RequestContext(request)
    currUser = User.objects.get(pk = id)
    profile = UserProfile.objects.filter(user = currUser)
    return render_to_response('myapp/profile.html', {'currUser': currUser}, context)

@login_required
@login_required
def add_post(request):
    context = RequestContext(request)
    if request.method == 'POST':
    #     #create a form instance and populate it with data from the request
        form = PostForm(request.POST)
        if form.is_valid():
             #process data in form.clean_data
            post = Post(user = request.user, title =form.cleaned_data['title'], body=form.cleaned_data['body'])
            post.save()
            return redirect(reverse('myapp/profile', args=[request.user.pk]))


    else:
        form=PostForm()

    return render_to_response('myapp/addpost.html', {'form': form}, context )

url.py

urlpatterns = patterns(
    '',
    ...
    url(r'^profile/(?P<id>\d+)/$', views.profile, name='profile'),
    url(r'^addpost/$', views.add_post, name='add_post'),

)

urlpatterns=patterns(
'',
...
url（r“^profile/（？P\d+/$”，views.profile，name='profile'），
url（r“^addpost/$”，views.add_post，name='add_post'），
)

只需重定向，无需执行

呈现到\u响应

from django.shortcuts import redirect
from django.core.urlresolvers import reverse

@login_required
def add_post(request):
    ....
    if form.is_valid():
        ....
        return redirect(reverse('profile', args=[request.user.pk]))

---

你把问题误诊了。这与重定向无关；它发生在模板本身中，因为您使用了

{%url'addpost%%}

而不是

{%url'add_post%%}

在发布成功后重定向到新视图。只需在发布成功后重定向（reverse（'profile'，args=[request.user.pk]）。它仍然不起作用。为了获得更多信息，我编辑并更新了上面的帖子。我得到了同样的反向错误。好的，我去掉了这个错误。我不得不把{%url'myapp:add_post%}放进去。这是一个愚蠢的错误。
