这里简单的演示完成一个 django 大概流程，后面会有详细解释
以下使用的是 ubuntu 系统
在生产环境中，有的时候，我们开发的项目可能用的是几个不同的 环境，所以通常我们会创建虚拟环境，在虚拟环境中安装我们需要的 配置，这里从配置虚拟环境开始
pip list pip freeze
pip install django==1.8.2
import django django.get_version()
表格需求：略
python manage.py startapp booktest
from django.db import models class BookInfo(models.Model): btitle = models.CharField(max_length=20) bpub_date = models.DateTimeField() def _ _str_ _(self): return "%d" % self.pk class HeroInfo(models.Model): hname = models.CharField(max_length=20) hgender = models.BooleanField() hcontent = models.CharField(max_length=100) hBook = models.ForeignKey(‘BookInfo‘)
# 上面创建了管理，外键 默认为对方的 主键 def _ _str_ _(self): return "%d" % self.pk # 这里创建了两个类，分别继承了 django.db 中的 models.Model 类，表示需要生成表头 # 定义 str 方法，表示默认输出
python manage.py makemigrations # 表的字段(表头)无论是增加删除还是类型改变后，都应该重新迁移
python manage.py migrate
from booktest.models import BookInfo,HeroInfo from django.utils import timezone from datetime import *
BookInfo.objects.all()
b = BookInfo() b.btitle="射雕英雄传" b.bpub_date=datetime(year=1990,month=1,day=10) b.save()
# 其它方式后面介绍
b=BookInfo.objects.get(pk=1) # pk 代表的是 主键 的意思，这里代指 id
b.btitle=u"天龙八部" b.save()
b.delete()
h=HeroInfo() h.htitle=u‘郭靖‘ h.hgender=True h.hcontent=u‘降龙十八掌‘ h.hBook=b h.save()
python manage.py runserver ip:port
python manage.py runserver 8080
python manage.py createsuperuser，按提示输入用户名、邮箱、密码
LANGUAGE_CODE = ‘zh-Hans‘ TIME_ZONE = ‘Asia/Shanghai‘
from django.contrib import admin from models import BookInfo admin.site.register(BookInfo)
class QuestionAdmin(admin.ModelAdmin):
...
admin.site.register(Question, QuestionAdmin)
list_display = [‘pk‘, ‘btitle‘, ‘bpub_date‘]
list_filter = [‘btitle‘]
search_fields = [‘btitle‘]
list_per_page = 10
fields = [‘bpub_date‘, ‘btitle‘]
fieldsets = [
(‘basic‘,{‘fields‘: [‘btitle‘]}),
(‘more‘, {‘fields‘: [‘bpub_date‘]}),
]
对于HeroInfo模型类，有两种注册方式
按照BookInfor的注册方式完成HeroInfo的注册
from django.contrib import admin
from models import BookInfo,HeroInfo
class HeroInfoInline(admin.StackedInline):
model = HeroInfo
extra = 2
class BookInfoAdmin(admin.ModelAdmin):
inlines = [HeroInfoInline]
admin.site.register(BookInfo, BookInfoAdmin)
class HeroInfoInline(admin.TabularInline)
def gender(self):
if self.hgender:
return ‘男‘
else:
return ‘女‘
gender.short_description = ‘性别‘
class HeroInfoAdmin(admin.ModelAdmin):
list_display = [‘id‘, ‘hname‘, ‘gender‘, ‘hcontent‘]
#coding:utf-8
from django.http import HttpResponse
def index(request):
return HttpResponse("index")
def detail(request,id):
return HttpResponse("detail %s" % id)
url(r‘^‘, include(‘booktest.urls‘)),
from django.conf.urls import url
from . import views
urlpatterns = [
url(r‘^$‘, views.index),
url(r‘^([0-9]+)/$‘, views.detail),
]
‘DIRS‘: [os.path.join(BASE_DIR, ‘templates‘)],
{{输出值，可以是变量，也可以是对象.属性}}
