AttributeError: 'QuerySet' object has no attribute 'tags' when trying to save quotes and tags with ClusterableModel and ClusterTaggableManager
AttributeError: 'QuerySet' object has no attribute 'tags' when trying to save quotes and tags with ClusterableModel and ClusterTaggableManager
我正在尝试使用 python manage.py shell 将 csv 文件中的一些引号保存到我的 django 模型中，因为我无法使用 django-import-export 来执行此操作。我在 Tags imported but relationship not imported with django-import-export 上询问过，但没有人回答，谷歌搜索后我找不到更多可以尝试的东西。
在阅读了此处关于 Django 查询集和标记的文档和之前的回答后，我设法保存了每个引用的大部分内容，但没有保存标记。查询集没有returntags字段，导致AttributeError。请参阅下面的 shell 输出 q: <QuerySet...
我的标签模型遵循 https://docs.wagtail.io/en/stable/reference/pages/model_recipes.html#custom-tag-models。
在 django-admin 中，关系正在发挥作用。 所以拼图的缺失部分是保存标签。
我应该使用什么查询来定位标签字段或者我应该使用什么方法来保存标签？

使用 Quote.objects.get(text__exact=row["text"].strip('"')) 有效。我预计 Quote.objects.filter(text__exact=row["text"].strip('"')) 到 return 1 个结果并认为它应该有效但我错了。
我在 python manage.py shell 中对此进行了测试并且有效。

q.tags.add(each)
q.save()
在q.tags.add(each)中，q是对象列表，所以不能直接使用tag。
遍历每个引用对象：
for q in Quote.objects.filter(text__exact=row["text"].strip('"')):
q.tags.add(each)
或通过get获得一个对象：
q = Quote.objects.get(text__exact=row["text"].strip('"'))
q.tags.add(each)
或过滤 return 个对象，例如使用 first:
q = Quote.objects.filter(text__exact=row["text"].strip('"')).first()
q.tags.add(each)
