一、django 的跨app引用文件是通过import 来实现的，但是import 的路径查找和标准的import 不太一样，django里面更加方便了

二、例子

1、project 结构说明

[jianglexing@workstudio fd]$ ll

total

drwxrwxr-x  jianglexing jianglexing   May  : fd

drwxrwxr-x  jianglexing jianglexing  May  : jiang

drwxrwxr-x  jianglexing jianglexing  May  : le

-rwxr-xr-x  jianglexing jianglexing  May  : manage.py

# fd      ---- project name

# jiang  ---- app name

# le      ---- app name

2、jiang/models.py

# jiang/models.py

from django.db import models

# Create your models here.

class classJiang(models.Model):

    name=models.CharField(max_length=8)

3、le/models.py 它会去引用jiang/models.py 文件中定义的classJiang

# le/models.py

from django.db import models

from jiang.models import classJiang #看到了吧、跨app引用、也好自然

# Create your models here.

class ClassLe(models.Model):

    name=models.CharField(max_length=8)

def testCrossFile():

    return str(classJiang)
