Django 程序结构

每个项目开始的时候，都要建立一个矿架。要建立statics，templates，并且在settings.py更改。 在statics下建立js，css，image等文件夹，并在settings.py配置。在templates下建立app_1,app_2。在settings.py中INSTALLED_APPS配置apis， app_1，app_2等等。

setting.py

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [
            os.path.join(BASE_DIR,'templates'),
        ],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

    'apis',

    'app_1',

    'app_2',
]

STATIC_URL = '/static/'

STATIC_ROOT = os.path.join(BASE_DIR, 'static')

STATICFILES_DIRS = (
    ('css', os.path.join(STATIC_ROOT, 'css').replace('\\', '/')),
    ('js', os.path.join(STATIC_ROOT, 'js').replace('\\', '/')),
    ('image', os.path.join(STATIC_ROOT, 'image').replace('\\', '/')),
)

在“工程”文件夹下建立views.py，存放主页的view。（只是为了整齐）。
在“工程”文件夹的urls.py加入include。导入apis，app_1，app_2等等的urls。

# project/urls.py
from django.conf.urls import url, include
from django.contrib import admin

import views

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^apis/', include('apis.urls')),
    url(r'^app-2/', include('app_2.urls')),
    url(r'^app-1/', include('app_1.urls')),
]

在templates下建立app_1,app_2。

templates
     |___app_1
     |___app_2
     |___app_3

在每个app文件夹下建立urls.py

from django.conf.urls import url

from . import views

app_name = "app_1"
urlpatterns = [

    url(r'^/xxx-1/(?P[0-9]+)/$', views.xxx_1, name='xxx_1'),
    
    url(r'^/xxx-2/$', views.xxx_2, name='xxx_2'),
]

每个app文件夹下建立views.py

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.contrib.auth.decorators import login_required
from django.http import HttpResponse
from django.shortcuts import render, redirect
from django.core import serializers
from django.views.decorators.csrf import csrf_exempt
from django.contrib.auth.decorators import login_required


# Create your views here.
from app_2.models import SomeModel

@login_required
def xxx_1(request, xxx_1_id):
    return HttpResponse("UNDER CONSTRUCTION!")

def xxx_2(request):
    return HttpResponse("UNDER CONSTRUCTION!")

def xxx_3(request):
        ...
        ...
    return render(request, "app_1/xxx_3.html", {"some_key_1":some_value_1, "some_key_2":some_value_2})

def xxx_4(request):
    return render(request, "app_1/xxx_4.html")

启动开发服务器

python manage.py runserver 8000

刷新数据库结构

python manage.py makemigrations

同步数据库

python manage.py migrate
