Question

制作了一个名为Blog的新应用，现在无法导入。创建了称为产品，页面的基本应用。现在，将另一个名为Blog的应用程序添加到项目中。无法解决迁移问题，终端最终没有名为“博客”的模型导入错误：

这是我的目录结构：

> Dev
    > python3
    > trydjango
        > src
            > blog
                > migrations
                > templates
                HTML FILES
                PYTHON FILE
            > pages
            > products
                > migrations
                > templates
            > templates
            > trydjango
            SETTINGS,URL,WSGI

这是BLOG / models.py文件：

from django.db import models

# Create your models here.


class Article(models.Model):
    title       =   models.CharField(max_length=120)
    abstract    =   models.CharField()
    author      =   models.CharField(max_length=100)
    created_on  =   models.DateTimeField(auto_now_add=True)

这是Blog / view.py文件：

from django.shortcuts import render

from django.views.generic import (
    CreateView,
    DetailView,
    ListView,
    UpdateView,
    ListView,
    DeleteView
)

from .models import Article
# Create your views here.


class ArticleListView(ListView):
    queryset = Article.objects.all()

Answer 1

我知道了。非常令人沮丧，尤其是来自python2。

无论模块是相对的还是绝对的，都必须向模块添加.。

Answer 2

正如Daniel所建议的那样，问题已得到解决，并且没有更多导入错误。谢谢。现在它使我陷入了奇怪的境地，因为我想创建以下两个任务：创建BLOG应用。在BLOG App中创建称为“文章”的模型。有什么好的解释吗？

ModuleNotFoundError：没有名为“博客”的模块
