首先在settings.py中引入

INSTALLED_APPS = [     ......     'rest_framework',     ...... ]

相关模型结构如下：

class custume(models.Model):     '''服装护具类'''     interno = models.CharField(max_length=50, verbose_name='内部商品编号', help_text='可以是数字或字母组合')     name = models.CharField(max_length=32, verbose_name='品名')     sort = models.ForeignKey(bm.custume_sort, verbose_name='衣着分类',on_delete=models.CASCADE,default=1)     supplier = models.ForeignKey(bm.supplier, verbose_name='供应商', on_delete=models.CASCADE, default=1)     brief = models.TextField(max_length=255,verbose_name='商品简述')     perunit = models.ForeignKey(bm.perunit,on_delete=models.CASCADE,verbose_name='计价单位',default=1)     reference_price = models.SmallIntegerField(verbose_name='参考价', help_text='随着价格变动，可能略有涨幅，以大佬定价为主',default=0)     class Meta:         db_table = 'custume'     def __str__(self):         return self.name

class supplier(models.Model):     '''供货商 '''     name = models.CharField(verbose_name='供货商名称', max_length=32)     contact = models.CharField(verbose_name='联系人', max_length=32)     sex = models.ForeignKey(gender,verbose_name='性别',on_delete=models.CASCADE,default=1)     def __str__(self):         return self.name     class Meta:         db_table = 'supplier' 在模块内新建site-package： serializer.py中定义相关模型serializer

class soxserializer(serializers.Serializer):     name = serializers.CharField()     interno = serializers.CharField()     supplier = serializers.CharField(source = "supplier.name")#外键字段

在views.py中定义相关表的接口类

class soxer(ModelViewSet):        queryset = sm.custume.objects.all()        serializer_class = soxserializer

在urls.py中定义相关表的url类 引入相关支持模块

from django.conf.urls import url, include from rest_framework import routers from shoppingcenter import views as sv router = routers.DefaultRouter() router.register(r'saiwa',sv.soxer)

urlpatterns = [    ......     url(r'^',include(router.urls)), 　　...... ]
