Django 增加admin site

Django1.4，在admin已经打开的前提下，新建立的模块希望自动加入到后台管理当中：

1.在app下新建admin.py,假设app名为jobs，内部新建了两个表Locaion, Job，内容如下:

from django.db import models
# Create your models here.
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)
    
    class Admin:
        list_display = ("city", "state", "country")     
        
    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)

则admin.py的内容为：

from jobs.models import Job
from jobs.models import Location

admin.site.register(Location)
admin.site.register(Job)

2.urls.py中需要打开admin自动扫描模式admin.autodiscover()，然后重新更新下数据库，重启即好。
