一、新建项目mysite以及在项目中新建应用blog

二、修改应用blog中的admin.py和models.py文件，如下

admin.py文件

from django.db import models
    from django.contrib.auth.models import User
    
    class BlogType(models.Model):
        type_name = models.CharField(max_length=15)
    
        def __str__(self):
            return self.type_name
    
    class Blog(models.Model):
        title = models.CharField(max_length=50)
        blog_type = models.ForeignKey(BlogType, on_delete=models.DO_NOTHING)
        content = models.TextField()
        author = models.ForeignKey(User, on_delete=models.DO_NOTHING)
        created_time = models.DateTimeField(auto_now_add=True)
        last_updated_time = models.DateTimeField(auto_now=True)
    
        def __str__(self):
            return "<Blog: %s>" % self.title

models.py文件

from django.contrib import admin
    from .models import BlogType, Blog
    
    @admin.register(BlogType)
    class BlogTypeAdmin(admin.ModelAdmin):
        list_display = ('id', 'type_name')
    
    @admin.register(Blog)
    class BlogAdmin(admin.ModelAdmin):
        list_display = ('title', 'blog_type', 'author', 'created_time', 'last_updated_time')

三、运行以下命令使Django项目运行并使数据库数据进行迁移

python manage.py runserver
    python manage.py makemigrations
    python manage.py migrate

然后进行使用   python manage.py createsuperuser   命令创建超级管理员，

python manage.py createsuperuser

四、接下来大功告成了，可以进入   [http://127.0.0.1:8000/admin/][http_127.0.0.1_8000_admin]   看到后台页面

五、接下来分别点击BLOG目录栏的Blog types和Blogs的增加按钮，进行博客和博文增加，如下图所示
