app的创建和注册

APP是用来存放代码的

创建APP

命令行创建,切换到项目目录下

python manage.py startapp appo1 #app01为项目名,创建完刷新即可

目录结构

把函数放到views后,别忘了要在urls.py中导入views

from django.conf.urls import url
from django.contrib import admin
from appo1 import views
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^log/', views.log),
    url(r'^index/',views.index)
]

pycharm创建

输入命令创建

manage.py@logserver > startapp app02

修改配置,使django能够识别新建的app,修改settings中的INSTALLED_APPS

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'appo1.apps.Appo1Config' #加上这句话
]

创建项目时创建app,创建后无需其他配置,pycharm已经帮我们配置好了
