Question

对不起，我的英语。

Dgango中的渲染模板存在一些问题。网址正确，但是模板返回错误。

所以URL是正确的，但是它返回了TASK-LIST，我期望TASK-DETAIL。我一个人找不到问题。

VIEWS.PY

from django.shortcuts import render
from .models import Task
from django.views import generic

# Create your views here.

def index(request):
    num_tasks = Task.objects.all().count()
    num_workers = Task.objects.all().filter(status='N').count()
    return render(request, 'index.html', context={'num_tasks':num_tasks,'num_workers':num_workers},)


class TaskListView(generic.ListView):
    model = Task
    paginate_by = 2

    def get_context_data(self, **kwargs):
        context = super(TaskListView, self).get_context_data(**kwargs)
        context['some_data'] = 'This is just some data'
        return context


class TaskDetailView(generic.ListView):
    model = Task

MODELS.PY

from django.db import models
from django.utils import timezone
from django.urls import reverse #Used to generate URLs by reversing the URL patterns


# Create your models here.
class Task(models.Model):
    STATUS_CHOICES = (
    ('A', 'Active'),
    ('R', 'Ready'),
    ('H', 'Hold'),
    ('N', 'Dont start')
    )
    task_name = models.CharField(max_length = 200, help_text = 'Укажите наименование задачи')
    date_start = models.DateTimeField(default=timezone.now)
    date_end = models.DateTimeField(default=timezone.now)
    worker = models.CharField(max_length = 200, help_text = 'Укажите сотрудника, которому назначена задача')
    status = models.CharField(max_length = 10, choices = STATUS_CHOICES, default = 'N')

    class Meta():
        ordering = ('date_start',)

    def __str__(self):
        return self.task_name

    def get_absolute_url(self):
        return reverse('task-detail', args=[str(self.id)])

应用程序路径中的URLS.PY：

from django.urls import path
from . import views
from django.conf.urls import url

urlpatterns = [
    path('', views.index, name='index'),
    path('tasks/', views.TaskListView.as_view(), name = 'tasks'),
    path('task/<int:pk>', views.TaskDetailView.as_view(), name = 'task-detail'),
]

PROJECT APP中的URLS.PY

from django.contrib import admin
from django.urls import path, include
from FirstPart import views
from django.views.generic import RedirectView

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('FirstPart.urls')),
    path('FirstPart/', include('FirstPart.urls')),
    path('', RedirectView.as_view(url='/FirstPart/', permanent=True)),
]

class TaskDetailView(generic.DetailView):
