Django 練習 #001

建立專案
django-admin.py startproject Play

開啟 DOS
cd C:\Users\Mortiz\Documents\Django\Play

資料庫連線設定
Play\Settings.py →


DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'Play', #Schema(Table)
        'USER': 'Moz',
        'PASSWORD': 'moz123',
        'HOST': '',
        'PORT': ''
    }

同步資料庫 & model
python manage.py syncdb
建立程式
python manage.py startapp First

model
First\model.py →


from django.db import models

class User(models.Model):
    Account = models.CharField(max_length=12)
    PW      = models.CharField(max_length=12)
    Name    = models.CharField(max_length=50)
    def __unicode__(self):
        return self.Name

view(controller)
First\views.py →


from django.shortcuts import render_to_response
from models import User

def getUserList(request):
    user_lsit = User.objects.order_by('-Name')
    return render_to_response('First/List.html'
                              , {'data_list':user_lsit}
           )

templates(view)
Firts\List.html →

<html><body> It is now  {{ data_list }}.</body></html>

將 model User添加到 INSTALLED_APPS
Play\Settings.py →


INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    # New
    'First', # folder name, not class name

model內不可建 id column, django會自動建立做為 primary key

from django.conf.urls import patterns, include, url

urlpatterns = patterns('',
                       url('^First/$'
                         , 'First.views.getUserList'
                         , name='hello'),
)

設定 templates(view)位址
Play\settings.py →


TEMPLATE_DIRS = (
    "C:\Users\Mortiz\Documents\Django\Play",
)
