model文件
~~~
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.db import models
# Create your models here.
class imgs(models.Model):
tetle = models.CharField(max_length=100, verbose_name=u"名称")
img = models.ImageField(upload_to="tt/%Y/%m", verbose_name=u"图片")
url = models.URLField(verbose_name=u"地址")
class Meta:
verbose_name = u"图片测试"
verbose_name_plural = verbose_name
def __str__(self):
return self.tetle
~~~
创建serializers.py 相当于表单
~~~
# _*_ coding=utf-8 _*_
__author__ = 'canmeng'
#相当于表单
from rest_framework import serializers
#from .models import imgs
#第一种形式，自定义属性
class ImgSerializer(serializers.Serializer):
tetle = serializers.CharField(required=True, max_length=100)
url = serializers.CharField(required=True, max_length=200)
img = serializers.CharField(required=True, max_length=200)
#第二种形式，引入model
#
# class ImgSerModel(serializers.ModelSerializer):
# class Meta:
# model = imgs
# fields = "__all__" 调用所有字段
# fields = ('tetle', 'img')
~~~
创建view
~~~
# -*- coding: utf-8 -*-
#api序列化
#from .serializers import ImgSerModel
from .serializers import ImgSerializer
from rest_framework.views import APIView
from rest_framework.response import Response
from .models import imgs
class ImgsList(APIView):
"""
图片列表
"""
def get(self, request, format=None):
ims = imgs.objects.all()
ims_ser = ImgSerializer(ims, many=True)
return Response(ims_ser.data)
~~~
项目URL 配置
~~~
from rest_framework.documentation import include_docs_urls
from imgs.views import ImgsList
urlpatterns = [
url(r'docs/', include_docs_urls(title="b")),
url(r'api-auth/', include('rest_framework.urls')),
url(r'tp/$', ImgsList.as_view(), name="tp")
]
