AttributeError：'ManyRelatedManager'对象没有属性'add'？ 我喜欢在Django的网站，但得到了这个错误

for item in data: category_id = item['category_id'] del item['category_id'] category = Category.objects.get(pk=category_id) code = item['code'] try: article = Article.objects.get(pk=code) except: article = Article(**item) article.save() # at this point I have the article & category, but the next # statement throws me an error: category.articles.add(article) category.save() 错误是： AttributeError: 'ManyRelatedManager' object has no attribute 'add'
