Windows下Python的Django框架环境部署及应用编写入门

from django.db import models 
 
class Location(models.Model): 
  city = models.CharField(max_length=50) 
  state = models.CharField(max_length=50, null=True, blank=True) 
  country = models.CharField(max_length=50) 
  def __str__(self): 
    if self.state: 
      return "%s, %s, %s" % (self.city, self.state, self.country) 
    else: 
      return "%s, %s" % (self.city, self.country) 
 
class Job(models.Model): 
  pub_date = models.DateField() 
  job_title = models.CharField(max_length=50) 
  job_description = models.TextField() 
  location = models.ForeignKey(Location) 
  def __str__(self): 
    return "%s (%s)" % (self.job_title, self.location) 

2、让模式生效：
在模式设计好了后就可以使用它，让它帮你干活啦，查看模式创建的表是否正确的命令为：manage.py sql app_dir， 这样可以查看表结构的原型了。在检查完表结构原型后就应用之，命令为：manage.py syncdb， 这个其实就是真正的在数据库中建表。

3、如何应用模式：
模式依然生效后就是如何去应用它，也就是获取其中的数据为我们服务；在views.py文件中包括如下代码即可调用具体的数据表；

from django.template import Context, loader 
from django.http import HttpResponse 
from myapp.models import Job 
 
 
def home(request): 
  object_list = Job.objects.order_by('-pub_date')[:10] 
  str_count = "The Count of job table is %s"%Job.objects.count() 
  str_job_desc = "<br>".str(join(Job.objects.all())) 
 
  return HttpResponse(str_count + "<br>" + str_job_desc) 

from django.contrib import admin 
from mydjango.myapp import models 
 
class DocumentAdmin(admin.ModelAdmin): 
  pass 
 
class CommentAdmin(admin.ModelAdmin): 
  pass 
 
admin.site.register(models.Location, DocumentAdmin) 
admin.site.register(models.Job, CommentAdmin) 

TEMPLATE_DIRS = ( 
  "C:/Users/xiaowu/workspace/mydjango/templates", ##注意斜线的格式，是/而不是\，即使在windows下 
)
