Build a Django app from scratch

$django-admin.py startproject web2$cd web2/$python manage.py startapp blog$vim web2

Note settings.py The following two sections, the first to configure the database, followed by the Installed_app to add the new app

DATABASES = {     'default': {        'ENGINE':'Django.db.backends.mysql',#Add ' postgresql_psycopg2 ', ' MySQL ', ' sqlite3 ' o        'NAME':'DJ_DB01',#Or Path to database file if using Sqlite3.        #The following settings is not used with Sqlite3:        'USER':'Root',        'PASSWORD':"',         'HOST':'localhost',#Empty for localhost through domain sockets        'PORT':"',#Set to empty string for default.    }   }

Installed_apps = (    'Django.contrib.auth',    'Django.contrib.contenttypes',    'django.contrib.sessions',    'django.contrib.sites',    'django.contrib.messages',    'Django.contrib.staticfiles',    'Blog',    #uncomment the next line to enable the admin:    'Django.contrib.admin',    #uncomment the next line to enable admin documentation:    'Django.contrib.admindocs',)

Next Edit models.py

$vim blog/models.py

 from Import Models

In MySQL, the corresponding data is created.

Mysql> CREATE DATABASE dj_db01 default CharSet UTF8;

You can now automatically generate various tables.

$ python manage.py syncdb

Now edit the config for the following URL

$vim web1/urls.py

 fromDjango.conf.urlsImportpatterns, include, url#uncomment the next lines to enable the admin:#From django.contrib Import admin#Admin.autodiscover ()Urlpatterns= Patterns ("',    #Examples:    #URL (r ' ^$ ', ' web1.views.home ', name= ' home '),    #URL (r ' ^web1/', include (' Web1.foo.urls ')),    #Uncomment the Admin/doc line below to enable admin documentation:    #URL (r ' ^admin/doc/', include (' Django.contrib.admindocs.urls ')),    #uncomment the next line to enable the admin:    #URL (r ' ^admin/', include (Admin.site.urls)),URL (r'^blog/$','Blog.views.index'),)

$mkdir blog/static/images

and copy it from somewhere else, and here I copy the img2.jpg.

Next Edit the page

$mkdir blog/Templates$vim Blog/templates/index.html

/static/images/img2.jpg'/>

Run for a minute

Python manage.py runserver 3900
