python - Django 在错误的应用程序中搜索 URL

Question

我的应用程序当前正在使用外部应用程序提供的 URLs 。我决定覆盖他们的一些观点，但这导致了 django 在错误目录中搜索 URL 的问题。

下面是我的一些代码来解释这个问题:

url.py(不是根配置，但它在我的主应用程序中)

urlpatterns = [
path('pipeline/<process_pk>/documents/<task_pk>/assign/',    #<---- this is the URL and view that i overrode
    OverrideTaskView.as_view(),
    {'flow_class': Pipeline,
    'flow_task': Pipeline.documents},
    name="pipeline:{}__assign".format(Pipeline.documents.name)),
path('pipeline/', include((pipeline_urls,'pipeline'))),   #<--- this is the app-supplied URLs

View .py

class OverrideTaskView(CoreAssignTaskView,FormView):  #<--- im inheritting the view from the third party app
form_class=AssignForm
action_name = 'assign'

def post(self, request, *args, **kwargs):
    if '_assign' or '_continue' in request.POST:
        self.activation.assign(self.request.user)
        return HttpResponseRedirect(self.get_success_url())  #<---- this is where it calls the faulty code
    else:
        return self.get(request, *args, **kwargs)

def get_success_url(self):                                   #<--- in this get success url the  self.request.resolver is returning the wrong value
    """Continue on task or redirect back to task list."""
    url = self.activation.flow_task.get_task_url(
        self.activation.task, url_type='guess', user=self.request.user,
        namespace=self.request.resolver_match.namespace + ':' + 'pipeline')

    back = self.request.GET.get('back', None)
    if back and not is_safe_url(url=back, allowed_hosts={self.request.get_host()}):
        back = '/'

    if '_continue' in self.request.POST and back:
        url = "{}?back={}".format(url, urlquote(back))
    elif back:
        url = back

    return url

这段代码:

url = self.activation.flow_task.get_task_url(
    self.activation.task, url_type='guess', user=self.request.user,
    namespace=self.request.resolver_match.namespace + ':' + 'pipeline')

正在返回错误的值:

cash

这是主应用程序的命名空间，但它应该返回:

cash:pipeline

有没有办法解决这个问题？

编辑

这是我覆盖的完整类，它属于一个名为 viewflow 的包

class AssignTaskView(MessageUserMixin, generic.TemplateView):
    """
    Default assign view for flow task.
    Get confirmation from user, assigns task and redirects to task pages

    if self.template_name is None:
        flow_task = self.activation.flow_task
        opts = self.activation.flow_class._meta

        return (
            '{}/{}/{}_assign.html'.format(opts.app_label, opts.flow_label, flow_task.name),

该应用程序基于它附带的 flow.py 抽象生成 URL，如果我没有错，这里是它的生成位置:

class FlowViewSet(object):
    """
    Shortcut for a flow urls routing.
    Usage::
        urlpatterns = [
            url(r'/helloworld/', include(FlowViewSet(HelloWorldFlow).urls))
        ]
    """
process_list_view = [
    r'^$',
    ProcessListView.as_view(),
    'index'
]

detail_process_view = [
    r'^(?P<process_pk>\d+)/$',
    DetailProcessView.as_view(),
    'detail'
]

cancel_process_view = [
    r'^action/cancel/(?P<process_pk>\d+)/$',
    CancelProcessView.as_view(),
    'action_cancel'
]

queue_list_view = [
    '^queue/$',
    QueueListView.as_view(),
    'queue',
]

archive_list_view = [
    '^archive/$',
    ArchiveListView.as_view(),
    'archive',
]

inbox_list_view = [
    '^tasks/$',
    TaskListView.as_view(),
    'tasks'
]

def __init__(self, flow_class):  # noqa D102
    self.flow_class = flow_class

def _create_url_entry(self, url_entry):
    regexp, view, name = url_entry
    return url(regexp, view, name=name)

def get_list_urls(self):
    """Collect urls from viewset class."""
    attrs = (getattr(self, attr) for attr in dir(self) if attr.endswith('_view'))
    return [
        self._create_url_entry(value)
        for value in attrs if isinstance(value, (list, tuple))
    ]

@property
def urls(self):
    """Collect the viewset and flow urls."""
    return [
        url('', include(self.get_list_urls()), {'flow_class': self.flow_class}),
        self.flow_class.instance.urls
    ]

这就是我生成的方式，我称之为 URL 生成器可以这么说:

pipeline_urls = FlowViewSet(Pipeline).urls

Answer 1

我正在回答我自己的问题，因为我发现了上述错误的问题。

通过改变

path('pipeline/', include((pipeline_urls,'pipeline')))

到

 path('pipeline/', include(pipeline_urls)),

问题解决了。
