python-3.x - 配置不当：循环导入以及项目的 url 中确实有模式

Question

我的项目网址

from django.contrib import admin
from django.urls import path,include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('',include('learn.urls')),
]

我的应用程序的网址

from django.urls import path
from .import views


urlpatterns = [
    path('',views.home,name='home'),
    path('notes',views.notes,name='notes'),
    path('delete_note/<int:pk>',views.delete_note,name='delete_notes'),
    path('detail/<int:pk>',views.detail.as_view(),name='detail'),
    path('homework',views.work,name='homework'),
    path('delete_hw/<int:pk>',views.delete_hw,name='delete_hw'),
    path('update/<int:pk>',views.update,name='update'),
    path('todo',views.todo,name=todo),
]

我的看法

from django.shortcuts import render,redirect
from .forms import *
from .models import *
from django.contrib import messages

from django.views.generic.detail import DetailView
def home(request):
    return render(request,'website/home.html')
def notes(request):
    if request.method == 'POST':
        form= notesform(request.POST)
        if form.is_valid():
            notes = Notes(user=request.user,title=request.POST['title'],description=request.POST['description'])
            notes.save()
        messages.success(request,f"Notes of {request.user.username} is added successfully")

    form = notesform()
    notes= Notes.objects.filter(user=request.user)
    context= {'notes':notes,'form':form}
    return render(request,'website/notes.html',context)

def delete_note(request,pk=None):
    Notes.objects.get(id=pk).delete()
    return redirect('notes')


def work(request):
    if request.method == 'POST':
        form = homeworkform(request.POST)
        if form.is_valid():
            try:
                finished = request.POST['is_finish']
                if finished == 'on':
                    finished = True
                else:
                    finished = False
            except:
                finished = False
            homeworks= homework(
                user= request.user,
                subject = request.POST['subject'],
                title = request.POST['title'],
                description=request.POST['description'],
                due= request.POST['due'],
                is_finish = finished
            )
            homeworks.save()
    else:
       form = homeworkform()
    Homework= homework.objects.filter(user=request.user)
    context = {'Homework':Homework,'form':form}
    return render(request,'website/hw.html',context)

def delete_hw(request,pk=None):
    homework.objects.get(id=pk).delete()
    return redirect('homework')

def update(request,pk=None):
    Homework = homework.objects.get(id=pk)
    if Homework.is_finish == True:
        Homework.is_finish = False
    else:
        Homework.is_finish = True
    Homework.save()
class detail(DetailView):
    model = Notes
    template_name = 'website/notes_detail'
    redirect('notes')

def todo (request):
    return render(request,'website/todo.html')

我的模型

from django.db import models
from django.contrib.auth.models import User
# Create your models here.

class Notes(models.Model):
    user= models.ForeignKey(User,on_delete=models.CASCADE)
    title=models.CharField(max_length=200)
    description=models.TextField()

    def __str__(self):
        return self.title

class homework(models.Model):
    user = models.ForeignKey(User,on_delete=models.CASCADE)
    subject = models.CharField(max_length=100)
    title = models.CharField(max_length=100)
    description = models.TextField()
    due = models.DateTimeField()
    is_finish = models.BooleanField(default=False)

    def __str__(self):
        return self.title
class Todo(models.Model):
    user = models.ForeignKey(User,on_delete=models.CASCADE)
    title = models.CharField(max_length=100)
    is_finish = models.BooleanField(default=False)

这是我的代码，我不知道发生在哪里以及为什么会这样

raise ImproperlyConfigured(msg.format(name=self.urlconf_name)) from e django.core.exceptions.ImproperlyConfigured：包含的 URLconf 'studyportal.urls' 似乎没有任何模式。如果您在文件中看到有效模式，则问题可能是由循环导入引起的。
