Question

我正在使用python 3.4和Django 1.8.2

我正在使用一些断言执行一些关于Artist对象的测试用例：

我希望该页面在我的/artist/<id>测试中返回（存储在res变量中）并返回200状态代码，即O.K.在http协议中

另外，我希望在内容中检查带有艺术家姓名的单词

from django.test import TestCase
from .models import Artists

class TestArtist(TestCase):
    def setUp(self):
        self.artist = Artists.objects.create(first_name = 'Ricky', 
        last_name ='Martin')

    def test_existe_vista(self):
        #print (self.client.get('/artists/%d' % self.artist.id))
        res = self.client.get('/artists/%d' % self.artist.id)
        self.assertEqual(res.status_code, 200)
        self.assertTrue('Ricky' in res.content)

输出结果为：

我的assertTrue断言中的TypeError: Type str doesn't support the buffer API是什么意思？

关于主题我还想要评论当我执行第一个测试或第一行（断言之前）我打印艺术家对象时，这个对象以这种方式打印：

如何打印人类可读的对象？

str 方法在我的admin.py文件中的测试用例中对我不起作用

关于SQLite警告我想我应该探索:) 谢谢

Answer 1

在这里完成同样的事情。尝试self.assertTrue('Ricky' in str(res.content))

TypeError：类型str不支持testcase中assertTrue中的缓冲区API
