Django-simpleUi项目开发流程

1.1首先自己安装把环境安装好，安装python，然后再命令行里输入:

$ pip install Django
$ pip install django-simpleui

1.2 在某个文件夹下，打开命令窗口

python startproject test1

1.3 可以直接运行

.py runserver

1.4 cd test1 创建booktest应用

python manage.py startapp booktest

1.5 创建应用后需要在settings.py 文件中 install_app 添加应用

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'booktest',
    'simpleui'
)

1. 6 写在booktest/model.py文件中，写入

from django.db import models

# Create your models here.
class BookInfo(models.Model):
    title=models.CharField(max_length=20)
    pub_date=models.DateField()

    def __str__(self):
        return self.title.encode('utf-8')

class HeroInfo(models.Model):
    name=models.CharField(max_length=10)
    content=models.CharField(max_length=100)
    gender=models.BooleanField(default=True)
    book=models.ForeignKey(BookInfo)

    def __str__(self):
        return self.name.encode('utf-8')

1. 7 使用sqlsite生成迁移文件

.py makemigrations

1. 8 根据迁移文件去创建数据库表结构

python manage.py migrate

1. 9 此处可以进行数据库操作

python manage.py shell
from booktest.models import BookInfo
    BookInfo.object.all() #查询
    b = BookInfo()
    b.title = '哈哈'
from datetime import date
    b.pub_date=date(2017,1,1)
    b.save()
    
    b=BookInfo.object.get(id=1)
    t.title='hujun'
    b.save()
    b.delete()
    
from booktest.models import HeroInfo
    b=HeroInfo()
    b.name='郭靖'
    b.gender=true
    b.content='降龙'
    b.book=BookInfo.object.get(id=2)
    b.save()

1. 10 后台管理,创建超级管理员

python manage.py createsuperuser

1. 11 在应用booktest的admin.py文件中进行注册

from django.contrib import admin
from .models import *
# Register your models here.

class BookInfoAdmin(admin.ModelAdmin):
    list_display = ['id','title','pub_date']
class HeroInfoAdmin(admin.ModelAdmin):
    list_display = ['id','name','content','gender','book']

admin.site.register(BookInfo,BookInfoAdmin)
admin.site.register(HeroInfo,HeroInfoAdmin)

1. 12 在应用booktest的views.py文件中进行视图编写

#coding=utf-8
from django.shortcuts import render
from django.http import HttpResponse
from .models import *
# Create your views here.
#HttpRequest
def index(request):
    #return HttpResponse('<h1>Hello World</h1>')
    return render(request,'booktest/index.html')

1. 13 在根目录下test1下的urls.py进行配置url ,加一条

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url('^',include('booktest.urls')),
]

1. 14 在应用booktest目录下添加一个urls.py文件

from django.conf.urls import url
from . import views
urlpatterns = [
    url('^$',views.index),
    url('^(\d+)/$',views.detail),
]

1. 15 在跟目录下新建一个template,和manage.py在同一级目录，然后在template目录再新建一个booktest目录，再在booktest目录下新建index.html，即test1/template/booktest/index.html

将views.py文件中的方法进行改写

#coding=utf-8
from django.shortcuts import render
from django.http import HttpResponse
from .models import *
# Create your views here.
#HttpRequest
def index(request):
    #return HttpResponse('<h1>Hello World</h1>')
    return render(request,'booktest/index.html')

1. 16 为了能够找到template文件夹，需要在settings.py文件中进行添加

TEMPLATES=[
    'DIRS':[os.path.join(BASE_DIR, 'templates')],
]

1. 17 在应用booktest的views.py文件中进行视图编写

#coding=utf-8
from django.shortcuts import render
from django.http import HttpResponse
from .models import *
# Create your views here.
#HttpRequest
def index(request):
    #HttpResponse
    # return HttpResponse('<h1>hello world</h1>')
    # context={'title':'django首页','list':range(10)}
    # return render(request,'booktest/index.html',context)
    list=BookInfo.objects.all()
    context={'booklist':list}
    return render(request,'booktest/index2.html',context)

def detail(request,id):
    list=BookInfo.objects.get(id=id).heroinfo_set.all()
    context={'herolist':list}
    return render(request,'booktest/detail.html',context)

1. 18 新建index2.html,在body写入

<ul>
{% for book in booklist%}
<l1><a href="/{{book.id}}"></a>{{book.title}}</l1>
{% endfor%}
</ul>

1. 19 在应用booktest的urls.py文件中添加

from django.conf.urls import url
from . import views
urlpatterns = [
    url('^$',views.index),
    url('^(\d+)/$',views.detail),
]

1. 20 在template/booktest的目录下新建detail.html

<ul>
{% for hero in herolist%}
<l1>{{hero.name}}</l1>
{% endfor%}
</ul>

注意： 改变数据库为mysql后，需要告诉django用pymysql替换它默认的mysql_db模块连接数据库，因为mysql_db现在已经没用了，所以需要替换模块。在项目文件夹下的__init__.py或者是应用文件夹下的__init__.py中加入以下语句。

import pymysql
pymysql.install_as_MySQLdb()
