有三张表，其中表customerGroup跟表discount是一对一关系，跟表product是多对多关系。

models.py

class customerGroup(models.Model):    name = models.CharField(max_length=100)    discount = models.ForeignKey("discount")    products = models.ManyToManyField("product",blank=True)        def __unicode__(self):        return self.name    class product(models.Model):    name = models.CharField(max_length=100)            def __unicode__(self):        return self.nameclass discount(models.Model):    name=models.CharField(max_length=30)    discountValue = models.DecimalField(max_digits=3,decimal_places=2)        def __unicode__(self):        return self.name

定义list_display的显示内容：

models.py中添加如下代码：

from django.contrib import adminclass customerGroupAdmin(admin.ModelAdmin):    list_display=('name','discountValue','product_list','comment')    filter_horizontal = ('products',)        def discountValue(self,obj):        return obj.discount.discountValue        def product_list(self,obj):        products=""        for product in obj.products.all():            products=product.name+","+products            return products    admin.site.register(customerGroup,customerGroupAdmin)

页面显示如下图：
