我再編寫獲取文章列表路基的時候，訪問介面地址報錯（127.0.0.1:8000/v1/topics/qq66907360）

經排查發現問題出在了這裡：
def make_topics_res(self,author,author_topics): res = {'code':200,'data':{}} topics_res = [] #遍歷出每一篇文章 for topic in author_topics: #組織資料 #{‘id’:1, ‘title’:’A’, ‘category’:’python’, ‘created_time’:’2021-12-15 21:07:20’, ‘introduce’:’AAA’, ‘author’:’qq66907360’} d={} d['id'] = topic.id d['title'] = topic.title d['category'] = topic.category d['create_time'] = topic.create_time.strftime("%Y-%m-%d %H:%M:%S") d['introduce'] = topic.introduce d['author'] = topic.author #author是文章模型類裡的一個外來鍵，是物件，這裡直接這樣寫是獲取不到作者名的，應該寫成:d['author'] = topic.author.username
