django初始创建核心流程

1. 创建虚拟环境

   pip install virtualenv
   
   virtualenv venv1
   
   #激活虚拟环境
   .\venv1\Scripts\activate
   

2. 安装django

   pip install django
   

3. 进入虚拟环境，创建django的项目

   django-admin startproject myblog
   

4. 启动测试服务器

   python manage.py runserver
   

5. 创建单个应用

   python manage.py startapp blog
   

6. 注册app

   # 在settings.py中
   INSTALLED_APPS = [
       'django.contrib.admin',
       'django.contrib.auth',
       'django.contrib.contenttypes',
       'django.contrib.sessions',
       'django.contrib.messages',
       'django.contrib.staticfiles',
       'blog', # 注册app
   ]
   

7. 将小应用的路由添加到项目的路由中去

   # myblog/urls.py
   from django.contrib import admin
   from django.urls import path, include
   
   urlpatterns = [
       path('admin/', admin.site.urls),
       path('', include('blog.urls')) # 加入app对应urls
   ]
   

8. 编写小应用的视图函数

   #blog/views.py
   from django.http import HttpResponse
   
   def index(request):
       return HttpResponse("请求路径:{}" .format(request.path))
   

9. 编写小应用的url

   # blog/urls.pyfrom django.urls import pathfrom . import viewsapp_name = "demo"urlpatterns = [    path('index/', views.index, name='index'),]
   

10. 创建模型

    # blog/models.py# 以下的代码只是样例，没有配置相关的urls.py和view.py    from django.db import modelsclass Status(models.TextChoices):	UNSTARTED = 'u', "Not started yet"    ONGOING = 'o', "Ongoing"    FINISHED = 'f', "Finished"        # Task模型class Task(models.Model):        name = models.CharField(verbose_name="Task name", max_length=65, unique=True)        status = models.CharField(verbose_name="Task status", max_length=1, choices=Status.choices)          def __str__(self):          return self.name
    

    有修改数据库就得执行以下语句

    python manage.py makemigrationspython manage.py migrate
    

11. 创建超级管理员

    python manage.py createsuperuser

个人感觉重点在于: 1.views.py 2.models.py
