制作 LiveCD

参考 ubuntu 官方
推荐一键制作
在 deepin 上操作, 脚本需要更改为: RELEASE=bionic, makecd.sh 代码如下:

其他尝试

创建虚拟盘 c.img 使用 bximage 即可
创建分区 (m: 帮助, n: 创建新分区, a: 添加引导标记, p: 查看, w: 保存)

sudo fdisk c.img

映射到 /dev/mapper

sudo kpartx -av c.img
ls -l /dev/mapper

根据映射 loop 格式化

sudo mkfs.ext4 /dev/mapper/loop0p1

安装 grub

sudo mount /dev/mapper/loop0p1 /mnt
sudo grub-install --boot-directory=/mnt/ /dev/loop0

复制 vmlinz initrd.img

sudo cp /boot/vmlinuz-4.15.0-30deepin-generic /mnt/boot/vmlinuz
sudo cp /boot/initrd.img-4.15.0-30deepin-generic  /mnt/boot/initrd.img

创建配置文件 grub.cfg，复制到 /mnt/boot/grub/ 中

default=0
timeout=10
insmod ext2
set root='hd0,msdos1'
menuentry 'x01.treeos' {
    insmod gzio
	insmod part_msdos
	insmod ext2
	set root='hd0,msdos1'
	linux /boot/vmlinuz ro --set=root --hint-bios=hd0,msdos1 --hint-efi=hd0,msdos1
	initrd /boot/initrd.img

Hello Django

Django for Beginner 学习笔记

安装 django

pip install django

新建目录 hello-django, 终端进入该目录分别运行以下命令

django-admin startproject django_project .
python manage.py migrate
python manage.py startapp pages

在 django_project/settings.py 的 INSTALLED_APPS 中添加 "pages":

INSTALLED_APPS = [
    ...
    "pages",
]

修改 pages/views.py 内容如下:

from django.shortcuts import render
from django.http import HttpResponse

# Create your views here.
def homne_page_view(request):
    return HttpResponse("hello world!")

新增 pages/urls.py 内容如下:

from django.urls import path 
from .views import homne_page_view

urlpatterns = [
    path("", homne_page_view, name="home"),
]

修改 django_project/urls.py 内容如下:

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

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

OK! 运行如下命令后, 可在浏览器中输入地址: http://127.0.0.1:8000 进行浏览.

python manage.py runserver

Pages App

添加 templates/pages/base.html, home.html, about.html

base.html

<header>
    <a href="{% url 'home' %}">Home</a> |
    <a href="{% url 'about' %}">About</a>
</header>

{% block content %} {% endblock content %}

home.html

{% extends "base.html" %}

{% block content %}
<h1>Home Page</h1>
{% endblock content %}

about.html

{% extends "base.html" %}

{% block content %}
<h1>About Page</h1>
{% endblock content %}

修改 django_project/settings.py

TEMPLATES = [
    {
        ...
        "DIRS": [BASE_DIR / "templates/pages"], # new
        ...
    },
]

修改 pages/views.py

from django.views.generic import TemplateView

class HomePageView(TemplateView):
    template_name = "home.html"

class AboutPageView(TemplateView):
    template_name = "about.html"

修改 pages/urls.py

from django.urls import path 
from .views import HomePageView, AboutPageView

urlpatterns = [
    path("", HomePageView.as_view(), name="home"),
    path("about", AboutPageView.as_view(), name="about")
]

OK! python manage.py runserver 运行之.

Posts App

新建应用 python manage.py startapp posts, 修改 django_project/settings.py

INSTALLED_APPS = [
    ...
    "posts",
]

修改 posts/models.py

from django.db import models

class Post(models.Model):
    text = models.TextField()

    def __str__(self) -> str:
        return self.text[:50]

分别运行

python manage.py makemigrations posts
python manage.py migrate
python manage.py createsuperuser

修改 posts/admin.py

from django.contrib import admin
from .models import Post

admin.site.register(Post)

修改 posts/views.py

from django.views.generic import ListView, TemplateView
from .models import Post

class HomePageView(ListView):
    model = Post 
    template_name = "posts/home.html"

class AboutPageView(TemplateView):
    template_name = "posts/about.html"

新建 templates/posts/base.html, home.html, about.html 等模板和URL: posts/urls.py, 修改 django_project/urls.py, 内容参考 Pages App, 不再赘述. OK! 运行无误.

Blog App

参考以上, 运行以下:

python manage.py startapp blog
# 添加 blog 到 settings.py => INSTALLED_APPS 中

blog/models.py

from django.db import models
from django.urls import reverse

class Post(models.Model):
    title = models.CharField(max_length=200)
    author = models.ForeignKey(
        "auth.User",
        on_delete = models.CASCADE,
    )
    body = models.TextField()

    def __str__(self) -> str:
        return self.title

    def get_absolute_url(self):
        return reverse("post_detail", kwargs={'pk': self.pk})

shell

python manage.py makemigrations blog
python manage.py migrate

blog/admin.py

from django.contrib import admin
from .models import Post

admin.site.register(Post)

新增 templates/blog/*, static, 修改 url, view 等

django_project/settings.py

STATIC_URL = "static/"
STATICFILES_DIRS = [BASE_DIR / "static"]

static/css/base.css

body {
    font-family: 'Source Sans Pro', sans-serif;
    font-size: 18px;
}

header {
    border-bottom: 1px solid #999;
    margin-bottom: 2rem;
    display: flex;
}

header h1 a {
    color: red;
    text-decoration: none;
    margin: 10px;
}

.nav-left {
    margin-right: auto;
}

.nav-right {
    display: flex;
    padding-top: 2rem;
}

.post-entry {
    margin-bottom: 2rem;
}

.post-entry h2 {
    margin: 0.5rem 0;
}

.post-entry h2 a,
.post-entry h2 a:visited {
    color: blue;
    text-decoration: none;
}

.post-entry p {
    margin: 0;
    font-weight: 400;
}

django_project/urls.py

urlpatterns = [
    ...
    path("blog/", include('blog.urls')),
]

blog/urls.py

from django.urls import path 
from .views import BlogListView, PostDetailView

urlpatterns = [
    path("", BlogListView.as_view(), name='home'),
    path("post/<int:pk>/", PostDetailView.as_view(), name='post_detail')
]

blog/views.py

from django.views.generic import ListView, DetailView
from .models import Post

class BlogListView(ListView):
    model = Post 
    template_name = "blog/home.html"

class PostDetailView(DetailView):
    model = Post 
    template_name = 'blog/post_detail.html'

Create, Update, Delete 等详见代码, 不过是添加修改模板, view, url 而已. OK!
login, logout, signin

修改 django_project/urls.py

urlpatterns = [
    ...
    path('accounts/', include('django.contrib.auth.urls')), 
]

新建目录: mkdir templates/registration 和文件 login.html

{% extends "blog/base.html" %}
{% block content %}

<h2>Log In</h2>
<form method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">Log In</button>
</form>

{% endblock content %}

blog/views.py 添加 logout

def logout_view(request):
    logout(request=request)
    return render(request=request, template_name='blog/home.html')

运行

删除 db.sqlite3
运行数据迁移 python manage.py migrate
创建超级用户 python manage.py createsuperuser
执行命令 python manage.py runserver
OK! 在浏览器中输入 http://127.0.0.1:8000/blog 即可.
