Django一般步骤记录
新建app
python manage.py startapp myapp
新增app路由
myapp下新建urls.py
from django.urls import path,include
from . import views
app_name='blog'
urlpatterns = [
path('', views.index,name='blogindex'),
]
项目下的urls.py
from django.contrib import admin
from django.urls import path,include
urlpatterns = [
path('admin/', admin.site.urls),
path('blog/',include('blog.urls')),
]
数据库模型
myapp下的models.py
from django.db import models
# Create your models here.
class Blog(models.Model):
name=models.CharField(max_length=100)
tagline=models.TextField()
def __str__(self):
return self.name
class Author(models.Model):
name=models.CharField(max_length=200)
email=models.EmailField()
def __str__(self):
return self.name
class Entry(models.Model):
blog=models.ForeignKey(Blog,on_delete=models.CASCADE)
headline=models.CharField(max_length=200)
body_text=models.TextField()
pub_date=models.DateField()
mod_date=models.DateField()
author=models.ManyToManyField(Author)
n_comments=models.IntegerField()
n_pingbacks=models.IntegerField()
rating=models.IntegerField()
def __str__(self):
return self.headline
项目下的settings.py ，将myapp加入Installedapp中
数据库迁移：
python manage.py makemigrations
python manage.py migrate
后台管理
myapp下的admin.py 中将models中的数据库表注册
from django.contrib import admin
from .models import Blog,Author,Entry
# Register your models here.
admin.site.register(Blog)
admin.site.register(Author)
admin.site.register(Entry)
新建管理员用户
python manage.py cteatesuperuser
开启服务器，使用pycharm的启动按钮或python manage.py runserver
此时，访问 http://127.0.0.1:8000/blog/ 和http://127.0.0.1:8000/admin/即可验证
