Django中各文件常用参数详解

1.Django常用命令

#新建Django项目django-admin startproject mysite（项目名）#新建一个APPcd my-sitepython manager.py startapp app01(app名)#同步数据库python manage.py makemigrationspython manage.py migrate#使用开发服务器python manage.py runserver 0.0.0.0:8000#清空数据库python manage.py flush#创建超级管理员python manage.py createsuperuser# 修改用户密码可以用：python manage.py changepassword username#更多命令python manage.py #可以看到详细的列表

2.settings.py文件

AUTH_USER_MODEL = 'users.UserProfile'#设置覆盖默认的User模型，其值引用一个自定义的模型。INSTALLED_APPS = ( #添加新建的app名到下面    ... ...    'app01',)TEMPLATES = [{    ... ...    'DIRS': [os.path.join(BASE_DIR, 'templates')], #添加模板文件路径，多个路径用逗号分隔    ... ...]DATABASES = {    'default': {        'ENGINE': 'django.db.backends.mysql', #使用MySQL引擎        'HOST':'127.0.0.1', #MySQL服务器ip        'PORT':3306, #MySQL端口号        'NAME':'djangotest', #MySQL数据库名        'USER': 'root', #MySQL用户名        'PASSWORD':'123456', ##MySQL用户密码    }}#STATIC_ROOT = os.path.join(BASE_DIR,'static') #定义静态文件根目录STATIC_URL = '/static/' #静态文件访问urlSTATICFILES_DIRS = [ #定义静态文件路径，多个路径用逗号隔开。---注意，该配置不与STATIC_ROOT同时使用    os.path.join(BASE_DIR,'static')]#session超时设置SESSION_EXPIRE_AT_BROWSER_CLOSE = True #在浏览器关闭时session超时SESSION_COOKIE_AGE = 60*30 #设置session超时时间，单位是秒        mysite/mysite/settings.py

3.项目的urls.py文件

#!/usr/bin/env python# -*- encoding: utf-8 -*-from django.conf.urls import include, urlfrom django.contrib import adminurlpatterns = [    url(r'^admin/', include(admin.site.urls)), #默认添加的后台管理功能    url(r'^app01/', include('app01.urls')), #将所有访问app01的utl都重定向到app01的urls.py文件]mysite/mysite/urls.py

4.APP的urls.py文件

#!/usr/bin/env python# -*- encoding: utf-8 -*-from django.conf.urls import include, urlurlpatterns = [    url(r'^login/', 'app01.views.login'), #url为login，调用app01的views.py文件下的login函数来实现    url(r'^index/', 'app01.views.index'),    url(r'^user/', 'app01.views.user'),    url(r'^usergroup/', 'app01.views.usergroup'),    url(r'^host/', 'app01.views.host'),]mysite/app01/urls.py

5.APP的models.py文件

from django.db import models# Create your models here.class server_fun_categ(models.Model): #创建名为server_fun_categ的表    id = models.IntegerField(primary_key=True, db_column='ID') #定义表字段id：整型、主键、列名为ID    server_categ_name = models.CharField(max_length=20) #定义表字段server_categ_name：char类型、最大长度为20        #Django特有方法，输出对象（models.table.object.all()获取的是一个对象）的某个值    #注意：该方法返回一个unicode对象，如果不是，比如数字，则返回一个TypeError    def __unicode__(self):         return self.server_categ_nameclass server_app_categ(models.Model):    id = models.IntegerField(primary_key=True, db_column='ID')    server_categ_id = models.ForeignKey(server_fun_categ)    app_categ_name = models.CharField(max_length=30)    def __unicode__(self):        return self.app_categ_nameclass server_list(models.Model):    server_name = models.CharField(max_length=13)    server_wip = models.GenericIPAddressField()    server_lip = models.GenericIPAddressField(unique=True)    server_op = models.CharField(max_length=10)    server_app_id = models.ForeignKey(server_app_categ)    def __unicode__(self):        return self.server_nameclass module_list(models.Model):    id = models.IntegerField(primary_key=True, db_column='ID')    module_name = models.CharField(max_length=20)    module_caption = models.CharField(max_length=255)    module_extend = models.CharField(max_length=2000)    def __unicode__(self):        return self.module_namemysite/app01/models.py

6.APP的admin.py文件.py文件)

#!/usr/bin/env python# -*- encoding: utf-8 -*-from django.contrib import adminfrom autoadmin import models# Register your models here.class ServerlistAdmin(admin.ModelAdmin):    list_display = ('server_name','server_wip','server_lip','server_op','server_app_id') #admin中列表显示项    search_fields = ('server_name','server_wip','server_lip','server_op','server_app_id') #添加搜索功能    list_filter = ('server_name','server_wip','server_lip','server_op','server_app_id') #添加快速过滤功能class ServerappAdmin(admin.ModelAdmin):    list_display = ('server_categ_id','app_categ_name')    search_fields = ('server_categ_id','app_categ_name')    list_filter = ('server_categ_id','app_categ_name')class ServerfunAdmin(admin.ModelAdmin):    list_display = ('server_categ_name',)    search_fields = ('server_categ_name',)    list_filter = ('server_categ_name',)class ModulelistAdmin(admin.ModelAdmin):    list_display = ('module_name','module_caption','module_extend')    search_fields = ('module_name','module_caption','module_extend')    list_filter = ('module_name','module_caption','module_extend') admin.site.register(models.server_list,ServerlistAdmin) #将模块添加到admin后台，进行可视化管理admin.site.register(models.server_app_categ,ServerappAdmin)admin.site.register(models.server_fun_categ,ServerfunAdmin)admin.site.register(models.module_list,ModulelistAdmin)mysite/app01/admin.py
