单击链接时，Django 未显示正确的路径答案

【问题标题】：Django is not showing the right path when clicking on a link单击链接时，Django 未显示正确的路径

【问题描述】：

这是点击链接时显示的内容

找不到页面 (404)

请求方法：GET 请求 URL： http://localhost:8000/jobapplication/new/1

使用 careal.urls 中定义的 URLconf，Django 尝试了这些 URL 模式，按以下顺序：

^$ [name='landing-index']

^管理员/

^帐户/

^任务管理器/

^login/$ [name='login']

问题是我不知道为什么它以http://localhost:8000/jobapplication/new/1打开链接，什么时候应该是http://localhost:8000/taskmanager/jobapplication/new/1

这就是我在 urls.py 中的内容

from django.conf.urls import include, url
    from django.contrib import admin
    from django.conf import settings
    from django.contrib.auth import views as auth_views
    from landingpage import views as landingpage_views

urlpatterns = [
        url(r'^$', landingpage_views.index, name='landing-index'),
        url(r'^admin/', admin.site.urls),
        url(r'^accounts/', include('allauth.urls')),
        url(r'^taskmanager/', include('taskmanager.urls')),
        url(r'^login/$', auth_views.login, name='login'),
]

这是在应用任务管理器的 urls.py 中

from django.conf.urls import url
from . import views
from taskmanager.views import *

app_name = 'taskmanager'
urlpatterns = [
 # Task manager urls
   url(r'^$', JobApplicationIndex.as_view(), name='index'),
   url(r'jobapplication/add/(?P<jobpost_id>[0-9]+)/$', JobApplicationCreate.as_view(), name='jobapplication-add'),
   url(r'jobapplication/new/(?P<jobpost_id>[0-9]+)/$', views.JobApplicationAdd, name='jobapplication-new'),
   url(r'jobapplication/edit/(?P<jobpost_id>[0-9]+)/$', views.JobApplicationEdit, name='jobapplication-edit'),
  url(r'jobapplication/edit/(?P<pk>[0-9]+)/$', JobApplicationUpdate.as_view(), name='jobapplication-edit'),
  url(r'^jobapplication/(?P<pk>[0-9]+)/$', JobApplicationDetails.as_view(), name='jobapplication-detail'),

# Company urls
url(r'company/$', CompanyIndex.as_view(), name='company-index'),
url(r'company/add/$', CompanyCreate.as_view(), name='company-add'),
url(r'^company/(?P<pk>[0-9]+)/$', CompanyDetails.as_view(), name='company-detail'),

# Job Post urls
url(r'jobpost/$', JobPostIndex.as_view(), name='jobpost-index'),
url(r'^jobpost/(?P<pk>[0-9]+)/$', JobPostDetails.as_view(), name='jobpost-detail'),

# Statistics urls
url(r'^kpi/$', views.kpi, name='kpi'),
]

这就是我在taskmanager中views.py中的内容，与jobapplication相关

# Job Application views
class JobApplicationIndex(generic.ListView):
template_name = 'taskmanager/jobapplication_index.html'

def get_queryset(self):
    if self.request.user.is_authenticated:
        return   JobApplication.objects.filter(user=self.request.user.id).order_by('-created_at')


class JobApplicationCreate(CreateView):
model = JobApplication
fields = ['jobpost', 'sent_date', 'deadline', 'success_rate']

def get_initial(self):
    jobpost = get_object_or_404(JobPost,  id=self.kwargs.get('jobpost_id'))
    return {
        'jobpost':jobpost,
    }

def form_valid(self, form):
    form.instance.user = self.request.user
    return super(JobApplicationCreate, self).form_valid(form)

class JobApplicationDetails(generic.DetailView):
model = JobApplication

class JobApplicationEdit(UpdateView):
model = JobApplication
#fields = ['jobpostid', 'is_favorite']
#p = JobApplication.objects.get(id=jobpostid)
#p.is_favorite = is_favorite
#p.save()


class JobApplicationUpdate(UpdateView):
model = JobApplication
fields = ['sent_date', 'deadline', 'success_rate']
template_name_suffix = '_update_form'


def JobApplicationAdd(request, jobpost_id):
 if request.method == 'GET' and request.user.is_authenticated:
    # If job app for this id exists, redirect to that job app page with a message
    if JobApplication.objects.filter(jobpost_id=int(jobpost_id)).exists():
        existing = JobApplication.objects.get(jobpost_id=int(jobpost_id))
        messages.add_message(request, messages.INFO, 'An application for this opening already exists.')
        return HttpResponseRedirect(reverse('taskmanager:jobapplication-detail', args=[existing.id]))

    jobapp = JobApplication(user=request.user, jobpost_id=int(jobpost_id), success_rate=50)
    jobapp.save()

return HttpResponseRedirect(reverse('taskmanager:index'))

---问题是taskmanager中的所有其他链接都在工作，当您单击它们时，会打开正确的路径例如：-

  - http://localhost:8000/taskmanager/jobpost/
  - http://localhost:8000/taskmanager/jobpost/2/
  - http://localhost:8000/taskmanager/company/2/
  - http://localhost:8000/taskmanager/kpi/

【解决方案1】：

尝试在正则表达式模式前添加一个上升趋势，就像你为那些正在工作的模式所做的那样。

from django.conf.urls import url
from . import views
from taskmanager.views import *

app_name = 'taskmanager'
urlpatterns = [
    # Task manager urls
    url(r'^$', JobApplicationIndex.as_view(), name='index'),
    url(r'^jobapplication/add/(?P<jobpost_id>[0-9]+)/$', JobApplicationCreate.as_view(), name='jobapplication-add'),
    url(r'^jobapplication/new/(?P<jobpost_id>[0-9]+)/$', views.JobApplicationAdd, name='jobapplication-new'),
    url(r'^jobapplication/edit/(?P<jobpost_id>[0-9]+)/$', views.JobApplicationEdit, name='jobapplication-edit'),
    url(r'^jobapplication/edit/(?P<pk>[0-9]+)/$', JobApplicationUpdate.as_view(), name='jobapplication-edit'),
    url(r'^jobapplication/(?P<pk>[0-9]+)/$', JobApplicationDetails.as_view(), name='jobapplication-detail'),

    # Company urls
    url(r'^company/$', CompanyIndex.as_view(), name='company-index'),
    url(r'^company/add/$', CompanyCreate.as_view(), name='company-add'),
    url(r'^company/(?P<pk>[0-9]+)/$', CompanyDetails.as_view(), name='company-detail'),

    # Job Post urls
    url(r'^jobpost/$', JobPostIndex.as_view(), name='jobpost-index'),
    url(r'^jobpost/(?P<pk>[0-9]+)/$', JobPostDetails.as_view(), name='jobpost-detail'),

    # Statistics urls
    url(r'^kpi/$', views.kpi, name='kpi'),
]

谢谢，我之前已经尝试过了，但结果还是一样。
