Python ModuleNotFoundError:没有名为'；posts.url'；

我从Django开始看教程，当我开始编辑URL.py时，我开始给出以下错误：

帖子的URL.py（文件夹）：

观点：

from django.shortcuts import render

def lista_post(request):
    return render(request,"Lista_post.html")

def post_singolo():
    return render(request,"post_singolo.html")

def contatti():
    return render(request,"Contatti.html")

请帮忙！ 我把url.py放在post文件夹的迁移文件夹中

第一个URL.py： C:\Users\Salva\mydjangoblog\mydjangoblog\mydjangoblog

第二个URL.py： C:\Users\Salva\mydjangoblog\mydjangoblog\posts\migrations

我正在使用Django 3.0.4

urls.py不应该在迁移文件夹中，而是在

你的应用程序/urls.py上

迁移文件夹包含创建数据库架构（创建和修改）所需的所有必要文件

使用

你的应用程序

我指的是你的应用程序名。我编辑了我的答案，添加了更多细节。谢谢，我修正了它。但现在我有另一个问题。请参阅我的下一篇文章。您是否在django安装的应用程序中安装了posts应用程序？注意，您的post.url已断开：urlpatterns列表中没有逗号。为什么要将此文件放入

migrations

文件夹？这地方不对。

from django.urls import path
from my_app import views as post_views

urlpatterns = [
    path(r'^',posts_views.lista_post, name="lista")
    path(r'^',posts_views.post_singolo, name="singolo")
    path(r'^',posts_views.contatti, name="contatti")
]

from django.shortcuts import render

def lista_post(request):
    return render(request,"Lista_post.html")

def post_singolo():
    return render(request,"post_singolo.html")

def contatti():
    return render(request,"Contatti.html")
